| 1 | Effects of N Forms and Rates on Vegetable Growth and Nitrate Accumulation显示文摘Experiments were carried out on a vegetable field with Peking cabbage (Brassica pekinensis (Lour.)Rupr.), cabbage (Brassica chinensis var. Oleifera Makino and nemoto), green cabbage (Brassica chinensis L.), spinach (Spinacia oleracea L.) and rape (Brassica campestris L.) to study the effects of N forms and N rates on their growth and nitrate accumulation. The results indicated that application of ammonium chloride,ammonium nitrate, sodium nitrate and urea significantly increased the yields and nitrate concentrations of Peking cabbage and spinach. Although no significant difference was found in the yields after application of the 4 N forms, nitrate N increased nitrate accumulation in vegetables much more than ammonium N. The vegetable yields were not increased continuously with N rate increase, and oversupply of N reduced the plant growth, leading to a yield decline. This trend was also true for nitrate concentrations in some vegetables and at some sampling times. However, as a whole, the nitrate concentrations in vegetables were positively correlated with N rates. Thus, addition of N fertilizer to soil was the major cause for increases in nitrate concentrations in vegetables. Nitrate concentrations were much higher in roots, stems and petioles than in blades at any N rate. | WANG Zhao-Hui and LI Sheng-XiuCollege of Resources and Environmental Sciences, Northwestern Science and Technology University of Agriculture and Forestry, Yangling 712100 (China).

| 2 | Carbon isotope ratios of C_(4) plants in loess areas of North China显示文摘Carbon isotope ratios (δ 13C) of 89 C4 plant samples were determined from the loess area in North China. δ 13C values vary between –10.5‰ and –14.6‰ with a mean of –12.6‰. Along a pre-cipitation gradient from the semi-moist area to the semiarid area, then to the arid area, the δ 13C val-ues of C4 plants show a slight decreasing trend. The δ 13C values of C4 plants in the dry season are found lower than those in the wet season. These trends are opposite to those observed for C3 spe-cies. | WANG Guoan1,2,3, HAN Jiamao 2, ZHOU Liping3, XIONG Xiaogang4, TAN Ming2, WU Zhenhai5 & PENG Jun6 1.

| 3 | Study on Wheat Cold Source and Its Characters显示文摘On the basis of tests and studies for many years, wheat cold source has been discovered in natural world. It is a donor material supplying a low temperature and causing stronger cooling effect, that is,the canopy temperature of its progeny can be descended universally and some non-cold type acceptor wheat can turn into cold type wheat having good metabolic functions under the condition of that acceptor wheat accepts the gamete of donor wheat supplying a low temperature. Contrast between wheat cold source and general wheat having no the ability of supplying a low temperature shows that second heat source temperature and plant temperature of wheat cold source not only are lower than those of general wheat but its root vigor, rate of awn etiolation, functional duration of leaf, chlorophyll content, soluble protein content, SOD activity, net photosynthetic rate, etc, are also more excellent than those of general wheat, and these all provide certain ecological and physiological bases for the distinction and selection of wheat cold source. | ZHANG Song-wu and WANG Chang-fa(Northwest Science and Technology University of Agriculture and Forestry, Yangling 712100) | 2002 | Agricultural Sciences in China2002，1，2： | 8 |

| 5 | The EST Analysis of A Suppressive Subtraction cDNA Library of Chinese Wild Vitis pseudoreticulata Inoculated with Uncinula necator显示文摘Uncinula necator is a worldwide serious fungus disease causing annual heavy lost on grapevine production. In order to get more informations on defense related EST sequences and help breeding program, we constructed and characterized a suppression subtractive hybridization cDNA library with artificially inoculated leaves and control Chinese wild Vitis pseudoreticulata clone Baihe-35-1, which is highly resistant to powdery mildew. In the library, the length of 58 EST fragments known as putative functions varied from 130 to 800 bp, and 60% of the ESTs exhibited high similarity to known sequences in database of GenBank with BLASTX analysis. These genes were involved in stress/defense response, detoxification, signal transduction, disease defense, and etc., and 14 ESTs remained unknown or hypothetical proteins, which may be new genes. The experiment provided an important basis for studying the disease-resistance mechanism and obtaining the genes for the aim of improving grapevine powdery mildew resistance. | SHI Jiang-li, WANG Yue-jin, ZHU Zi-guo and ZHANG Chao-hong Key Laboratory of Horticultural Plant Germplasm Utilization in Northwest China, Ministry of Agriculture/Shaanxi Key Laboratory of Molecular Biology for Agriculture/College of Horticulture, Northwest A&F University, Yangling 712100, P.R.China | 2010 | Agricultural Sciences in China2010，9，2： | 5 |

| 9 | Erosion environment in the sediment-rich area on the Loess Plateau显示文摘Based on the investigation and analysis of characteristics of precipitation, natural environment, socio-economic factors and soil erosion, this paper indicates that the precipitation is the main driving force for the soil erosion in the sediment-rich area, its variability determines the characteristics of soil and water loss; the natural conditions such as the drainage systems, geological and topographic features, the composition of soil and land surface materials, vegetation and climate determine the seriousness of soil and water loss; irrational socio-economic activities of human beings usually accelerated soil and water loss; meanwhile, the low preservation rate and inferiority of soil and water conservation measures made it impossible to make rapid progress on soil and water loss control. Furthermore, the characteristics of erosion environment endowed this area with more sediment that is the main reason for the flooding disasters by the Yellow River. Therefore, more emphasis should be placed on the enhancement of soil and water conservation. The soil loss prediction models will provide scientific basis for the planning of soil and water conservation, the designing of soil and water conservation measures and the valuation of effects of soil and water loss control. According to the analysis of the previous studies on soil loss prediction, and the water-sediment variation features, it is thought that study on soil loss prediction under various rainfall conditions and soil-water conservation measures should be carried out. | JIAO Ju-ying, LI Jing, WANG Wan-zhong (Institute of Soil and Water Conservation, CAS and Ministry of Water Resources Northwest Sci-techonology University of Agriculture and Forestry, Yangling 712100, China) | 2002 | Journal of Geographical Sciences2002，12，1： | 3 |
| 10 | Histology and Ultrastructure of Incompatible Combination Between Puccinia striiformis and Wheat Cultivars with Low Reaction Type Resistance显示文摘The incompatible combinations between races of Puccinia striiformis and wheat cultivars with low reaction type resistance were examined by means of fluorescent microscopy, differential interference contrast microscopy and electron microscopy. The incompatible combinations consisted of wheat cultivar Niuzhute plus CY28, Hybrid46 plus CY29 and Tianxuan882 plus CY29, while the compatible combination was wheat cultivar Huixianhong plus CY28. The observation revealed a striking difference in the fungal development and the host responses between susceptible and resistant wheat cultivars following infection by the pathogen. The main histological manifestation of the pathogen development in the resistant wheat cultivars include inhibition of hyphal growth, delay of hyphal branching and colony formation, decrease of formation of haustorial mother cells and haustoria, and occurrence of host cell necrosis. The observation by electron microscopy demonstrated that a series of abnormal changes occurred in intercellular hyphae, haustorial mother cells and haustoria during pathogen development in the resistant wheat cultivars. The cytoplasm became more electron-dense and vacuoles in the cytoplasm increased in number and size. The cell walls of hyphae, haustorial mother cells were thickened irregularly. The organelles were disorderly distributed in the cytoplasm and the haustorial mother cells and haustoria lost their physiological function. In the final stage of the pathogen development, the intercellular hyphae, haustorial mother cells and haustoria became necrotic and collapsed. The structural defense reactions such as formation of cell wall apposition, collar and encasement of haustorium were essentially more pronounced in the infected wheat leaves of the resistant cultivars than in the susceptible one. In addition, the relationship between the host resistance expression and the histological and cytological features occurred in the incompatible combination was discussed in this paper. | KANG Zhen-sheng, WANG Yao, HUANG Li-li, WEI Guo-rong and ZHAO Jie (Shaanxi Provincial Key Lab of Molecular Biology for Agriculture/Plant Protection College, Northwest Sci-Tech University of Agriculture and Forestry, Yangling 712100, P.R.China) | 2003 | Agricultural Sciences in China2003，2，10： | 3 |
| 11 | Origin and evolution of new exons in the rodent zinc fingerprotein 39 gene显示文摘The origin of new structures and functions is an important process in evolution. In the past decades, we have obtained some preliminary knowledge of the origin and evo- lution of new genes. However, as the basic unit of genes, the origin and evolution of exons remain unclear. Because young exons retain the footprints of origination, they can be good materials for studying origin and evolution of new exons. In this paper, we report two young exons in a zinc finger protein gene of rodents. Since they are unique sequences in mouse and rat genome and no homologous sequences were found in the orthologous genes of human and pig, the young exons might originate after the divergence of primates and rodents through exonization of intronic sequences. Strong positive selection was detected in the new exons between mouse and rat, suggesting that these exons have undergone significant functional divergence after the separation of the two species. On the other hand, population genetics data of mouse dem- onstrate that the new exons have been subject to functional constraint, indicating an important function of the new exons in mouse. Functional analyses suggest that these new exons encode a nuclear localization signal peptide, which may me- diate new ways of nuclear protein transport. To our knowl- edge, this is the first example of the origin and evolution of young exons. | PENG Lixin1,2*, ZHENG Hongkun3*, LI Xin1,2, YANG Shuang2,4, CHEN Hong1,5 & WANG Wen2 1.

| 12 | Effects of Microtubule Polymerization Inhibitor on the Hypersensitive Response of Wheat Induced by the Non-Host Pathogen Sphaerotheca fuliginea显示文摘The plant cytoskeleton is a highly dynamic and versatile intracellular scaffold composed of microtubules and microfilaments, serving a multiplicity of functions in plant cells. To reveal the relationship between the cytoskeleton in wheat (Triticum aestivum L.) cv. Suwon 11 attacked by the non-host pathogen Sphaerotheca fuliginea and the initiation of the hypersensitive response, the microtubule inhibitor oryzalin was injected into the wheat leaves immediately prior to inoculation. The incidence of hypersensitive cell death was significantly lower than that in water-treated control. In addition, the occurrence of hypersensitive cell death was also delayed and S. fuliginea was able to penetrate and form haustoria in epidermal tissues of wheat. All the results above indicated that hypersensitive cell death was associated with depolymerisation of microtubules, suggesting that microtubules might play an important role in the expression of non-host resistance of wheat. | LI Hong-li, WANG Hai-yan, HAO Xin-yuan, SONG Xiao-he and MA Qing College of Plant Protection and Shaanxi Key Laboratory of Molecular Biology for Agriculture, Northwest A&F University/Key Laboratory of Plant Protection Resources and Pest Management, Ministry of Education, Yangling 712100, P.R.China | 2010 | Agricultural Sciences in China2010，9，3： | 3 |
| 13 | NH3 Volatilization from Aboveground Plants of Winter Wheat During Late Growing Stages显示文摘Ammonia volatilized from aboveground parts of winter wheat was collected with an enclosuregrowth chamber and measured from jointing to maturing stage. The results showed that ammonia releasedfrom unfertilized plants grown in high and low fertility soils remained at low rates of 2.3 and 0.9 μg NH3 40plant-1 h-1 respectively at late filling stage. However, fertilized plants rapidly increased the rates to 43.4 and52.2 μg NH3 40 plant-1 h-1 in the high and low fertility soils, respectively, at the same period. The released a-mount was different in different parts of plants. At filling stage, lower senescing stems and leaves volatilizedmore ammonia than upper parts, i.e. , ears and flag leaves that grew normally, with an average of 1.4 and0.7 μg NH3 20 plant-1 h-1 respectively, strongly suggesting that it was the senile organs that released largeamounts of ammonia. At the grain filling stage, shortage of water supply (drought stress) reduced ammoniavolatilization. The average rate of ammonia released under water stress was 0.9 μg NH3 40 plant-1 h-1 , but 1.2μg NH3 40 plant-1 h-1 with moderate water supply. Application of N together with P fertilizer resulted in ahigher ammonia volatilization than N fertilization alone at the maturing stage. The average rate released was135.3 μg NH3 40 plant-1 h-1 when 0.4 g N and 0.13 g P had been added to per kg soil, while 33.7 μg when0.4 g N added alone. Ammonia volatilization from plants was closely related with plant biomass and N up-take; P fertilization increased plant biomass and N uptake and therefore increased its release. | WANG Zhao-hui and LI Sheng-xiuCollege of Resources and Environmental Sciences, Northwestern Science and Technology University of Agricultureand Forestry, Yangling 712100, P.

| 14 | Using soil surface gray level to determine surface soil water content显示文摘How to determine surface soil water content(SWC) quickly and accurately is fundamental in studying eco-hydrological processes and their modeling.Here we use laboratory experiments to determine surface SWC using soil surface gray level(SGL) values.A negatively exponential relationship exists between SGL and SWC,i.e.,SGL increases with the decrease of SWC.SGL can be estimated based on initial SGL value(surface gray level when SWC=0),SWC,and a surface roughness coefficient characterized by mean soil particle size.The variation range of SGL was larger than that of SWC,indicating that changes in SWC were enhanced in SGL,and that SGL would thus be sensitive to changes in soil water.At the 95% confidence level,SWC can be determined by using the relationship between SWC and SGL established by the experiments.The determination of SWC has a high precision when SWC was between dry and saturated. | ZHU YuanJun1,2,WANG YunQiang1,2 & SHAO MingAn1,2 1 State Key Laboratory of Soil Erosion and Dryland Farming on Loess Plateau,Institute of Soil and Water Conservation,Northwest A & F University,Yangling 712100,China 2 Institute of Soil and Water Conservation,Chinese Academy of Sciences & Ministry of Water Resources,Yangling 712100,China | 2010 | Science China Earth Sciences2010，53，10： | 2 |
| 15 | MODELING OF INTERRILL EROSION INTHE LOESS PLATEAU OF CHINA显示文摘Based on the field plots data from simulated rainfall experiments, a theoretical model for calculating the kinetic energy of a single raindrop was developed in the Loess Plateau of China Formulae for both single raindrops and rainfall events are presented in this paper.Analysis shows that overland flow and the area producing runoff on the land surface increase with the duration of rainfall, while the effects of raindrop impact on the surface of the hillslope decrease. The rate of interrill erosion decreases gradually with the rainfall duration. A physically-based formula to calculating the area of runoff production is also given in this paper The overland flow and canopy affect jointly the interrill erosion processes. The paper presents an equation to quantitatively evaluate the effect. It is concluded thats (1) the peak rate of interrill erosion is related to rainfall intensity, rainfall kinetic energy, and slope; and (2) the average rate of interrill erosion during an individual time period for variable rainfall intensity varies with the rainfall intensity, rainfall duration and runoff producing area. | Zhanbin LI Mingan SHAO & Zhanli WANG Bing SHEA (Institute of Soil and Water Conservation, Chinese Academy of Sciences and Ministry of Water resources.

| 16 | Cytomorphology and Cytochemical Localization of K-type and T-type Cytoplasmic Male Sterile Pollens in Wheat显示文摘By using the technology of microscopy,electron microscopy and enzyme cytochemical localization, comparison was made of the cytomorphology, ATPase and cytochrome oxidase activity in pollens during microspore formation and pollen development, for K-type cytoplasmic male sterile (CMS) lines, T-type CMS lines and their maintainer lines on wheat. The results indicated that pollen abortion of the T-type CMS lines mainly occurred at the later mononucleate pollen stage, and cytomorphological changes of the abortive pollen began with a vacuolar membrane, and pollen aborting was related to a lack of ATPase activity in the nucleus and nucleolus during the mononucleate pollen stage. Pollen abortion of the K-type CMS lines took place mainly during the later binucleate and trinucleate stages, and cytomorphological changes of the abortion first began with mitochondria. The abortion was related to intine disruption. | YAO Ya-qin, ZHANG Gai-sheng, LIU Hong-wei and WANG Jun-wei(Northwest Sci-Tech University of Agriculture and Forestry , Yangling 712100 , P. R.

| 20 | Large-scale information entropy analysis of important sites in mature and precursor miRNA sequences显示文摘In order to find evidence of consistent sequence conservation or the base correlation degree in miRNA,some important sites in the sequences of reported miRNA and their precursors(pre-miRNA) were investigated via information entropy analysis.Twelve different groups of sites were obtained from special locations(head,tail) in miRNAs of different sources according to taxonomy(animal,plant and virus) and then analyzed by measuring the single base information redundancy(D1(L)) and the adjacent base related information redundancy(D2(L)).The results showed that D2(L) has more information than D1(L),though D1(L) changes roughly consistently with D2(L) in each group.Viral pre-miRNAs are more conservative than those belonging to animals or plants.In addition,U is dominant in most sites compared with other nucleotides.It was also found that in the middle of several groups,there were sites where miRNAs were cut down from pre-miRNAs by Enzyme Dicer which were significantly conservative.This phenomenon shows that the conservatism is an aspect of the of miRNA and may be involved in the recognition and cutting by the Dicer.Those results provided another perspective for understanding more about the primary structure of pre-miRNA. | DU JiangFeng1,2,WU YongJun2,ZHANG YinXia3,WU Lei1,2,WANG XiaoLong3,TAO ShiHeng1,2 1 Bioinformatics Center,Northwest Science and Technology University of Agriculture,Yangling 712100,China 2 College of Life Sciences,Northwest Science and Technology University,Yangling 712100,China 3 College of Science,Northwest Science and Technology University,Yangling 712100,China | 2009 | Science China(Life Sciences)2009，52，8： | 1 |
