| 1 | Responses of wheat seedlings to cadmium,mercury and trichlorobenzene stresses显示文摘The molecular response of wheat(Triticum aestivum L.,cv.Yangmai 13) seedlings to heavy metal(Cd,Hg) and 1,2,4-trichlorobenzene(TCB) stresses were examined by two-dimensional gel electrophoresis,image analysis,and peptide mass fingerprinting.The results showed inhibitions of root and shoot growth by Cd,Hg,and TCB.These stresses led to water deficit and lipid phosphorylation in the seedling which also promoted protein phophorylation in the leaves.Hg stress inhibited protein synthesis while Cd and TCB stresses induced or up-regulated more proteins in the leaves.Most of these induced proteins played important roles in the biochemical reactions involved in tolerance of wheat to Cd and TCB stresses.The primary functions of Cd-and TCB-induced proteins included methionine metabolism,Rubisco modification,protein phosphorylation regulation,protein configuration protection,H+ transmembrane transportation and also the synthesis of ethylene,defense substances and cell wall compounds. | GE Cailin DING Yan WANG Zegang WAN Dingzhen WANG Yulong SHANG Qi LUO Shishi | 2009 | Journal of Environmental Sciences2009，21，6： | 12 |
| 2 | Do anogenital gland secretionsof giant panda code for their sexual ability?显示文摘To test the hypothesis of whether ano- genital gland secretions (AGS) of giant panda code for their sexual ability, we collected AGS samples of 11 male (5 adult and 6 subadult) and 14 female (7 adult and 7 subadult) captive giant pandas (Ailuro- poda melanoleuca) from China Research and Con- servation Center for the Giant Panda at Wolong, Si- chuan, China from 1994 to 2002. The samples were analyzed by GC and GC-MS. The GC results showed that male and female pandas shared 20 constituents with equal capacity factors in the AGS. Further GC-MS analyses showed that there were a total of 95 compounds in the AGS. Nine constituents for the males and three for the females differed significantly in relative abundances between sexually active and inactive individuals, but no clear division between sexually active and inactive pandas by hierarchical cluster analyses on the relative abundances of a subset of 56 compounds. However, we were able to separate different age groups of male pandas by the constituents of AGS. 14 compounds were found sig- nificantly and negatively, and 8 compounds positively, correlated with pandas’ age by year. Our results suggest that the information contained in the AGS of panda might not code for pandas’ sexual ability but might for their age. These results will be valuable for captive breeding and conservation in the wild. | LIU Dingzhen YUAN Hong TIAN Hong WEI Rongping ZHANG Guiquan SUN Lixing WANG Liwen SUN Ruyong | 2006 | Chinese Science Bulletin2006，51，16： | 7 |

| 4 | Seasonal and reproductive variation in chemical constituents of scent signals in wild giant pandas显示文摘Seasonally reproducing animals show many behavioral and physiological changes during the mating period, including increased signaling for intrasexual competition and mate attraction. We collected 102 anogenital gland secretions(AGS) from marking trees in Foping Nature Reserve, and used gas chromatography mass spectrometry to analyze these chemical composition. Of these marks, all but one were from males, confirmed with DNA analysis. We found that several chemical constituents, especially volatile compounds, were present only during the mating season and that the relative abundance of many compounds changed as a function of breeding season, whereas nonvolatile compounds were lower in the mating season. This seasonal variation in chemical composition of AGS most likely plays an important role in governing giant panda reproduction, including mate location, attraction, and male-male competition. The chemical properties of many of these putative chemosignals—such as volatility and longevity—are suggestive of these roles, and undoubtedly contribute to successful reproduction for this species with a characteristically sophisticated chemical communication system. We also found a number of important differences between the chemical constituents of AGS from wild pandas and those found in previous studies with captive pandas, suggesting that inappropriate chemosignal composition may contribute to poor reproductive success in captive breeding programs. | Wenliang Zhou Yonggang Nie Yibo Hu Ronald R.Swaisgood Yaohua Zhang Dingzhen Liu Fuwen Wei | 2019 | Science China(Life Sciences)2019，62，5： | 6 |
| 5 | Male panda (Ailuropoda melanoleuca) urine contains kinship information显示文摘Chemical communication plays an important role in kin selection and mate choice in mammals. The covariance of odor-genes of rodents has been documented and kinship odor has been proposed and termed, yet little is known of the relationship between genetic relatedness and chemical composition of kinship odors. Giant pandas (Ailuropoda melanoleuca) rely substantially on chemical communication to mediate their social interactions. To examine the relationship between genetic relatedness and compounds in the urine/anogenital gland secretions, we compared the similarities between genetic relatedness and the chemical profiles of anogenital gland secretions and urine via lineage construction and GC-MS (gas chromatography and mass spectrometry). We found that information about kinship odors was present only in the urine of male adults in the mating season but absent in the non-mating season. Adult females and all sub-adults did not have such kinship odors in either mating or non-mating season. Therefore, kinship odor in the panda was contingent on age, sex, and season. This is the first report about the condition-dependent expression of kinship odor, which may have a sig- nificant implication in the practice of panda conservation in relation to chemical communication and sexual selection. | LIU DingZhen WEI RongPing ZHANG GuiQuan YUAN Hong WANG ZhiPeng SUN Lixing ZHANG Jianxu ZHANG HeMin | 2008 | Chinese Science Bulletin2008，53，18： | 6 |

| 19 | Vomeronasal organ lesion disrupts social odor recognition, behaviors and fitness in golden hamsters显示文摘Most studies support the viewpoint that the vomeronasal organ has a profound effect on conspecific odor recognition,scent marking and mating behavior in the golden hamster(Mesocricetus auratus).However,the role of the vomeronasal organ in social odor recognition,social interaction and fitness is not well understood.Therefore,we conducted a series of behavioral and physiological tests to examine the referred points in golden hamster.We found that male hamsters with vomeronasal organ lesion showed no preference between a predator odor(the anal gland secretion of the Siberian weasels(Mustela sibirica)and putative female pheromone components(myristic acid and palmitic acid),but were still able to discriminate between these 2 kinds of odors.In behavioral tests of anxiety,we found that vomeronasal organ removal causes female hamsters to spend much less time in center grids and to cross fewer center grids and males to make fewer crossings between light and dark boxes than sham-operated controls.This indicates that a chronic vomeronasal organ lesion induced anxious responses in females.In aggressive behavioral tests,we found that a chronic vomeronasal organ lesion decreased agonistic behavior in female hamsters but not in males.The pup growth and litter size show no differences between the 2 groups.All together,our data suggested that vomeronasal organ ablation disrupted the olfactory recognition of social chemosignals in males,and induced anxiety-like and aggressive behavior changes in females.However,a vomeronasal organ lesion did not affect the reproductive capacity and fitness of hamsters.Our studies may have important implications concerning the role of the vomeronasal organ in golden hamsters and also in rodents. | Yingjuan LIU Jinhua ZHANG Dingzhen LIU Jianxu ZHANG | 2014 | Integrative Zoology2014，9，3： | 0 |
| 20 | Kinship alters the effects of forced cohabitation on body weight,mate choice and fitness in the rat-like hamster Tscheskia triton显示文摘It has been documented that social isolation imparts deleterious effects on gregarious rodents species,but caging in group imparts such effects on solitary rodents. This study was attempted at examining how kinship to affect body weight,behavioral interaction,mate choice and fitness when we caged male and female rat-like hamsters Tscheskia triton in pair,a solitary species. We found that females paired with nonsibling males became heavier than the females paired with sibling males,but both agonistic and amicable behavior between paired males and females did not differ between sibling and nonsibling groups. This indicated that kinship might reduce females' obesity in response to forced cohabitation,and dissociation might exist between physiological and behavioral responses. Furthermore,binary choice tests revealed that social familiarity between either siblings or nonsiblings decreased their investigating time spent in opposite sex conspecific of cage mates and/or their scents as compared with those of non-mates,suggesting effects of social association on mate and kin selection of the hamsters. On the other side,both females and males caged in pair with siblings show a preference between unfamiliar siblings or their scents and the counterparts of nonsiblings after two month separation,indicating that the kin recognition of the hamsters might also rely on phenotype matching. In addition,cohabitation (or permanent presence of fathers) elicited a lower survival of pups in nonsibling pairs than sibling pairs,but did not affect litter size,suggesting that kinship affects fitness when housing male and female ratlike hamsters together. Therefore,inbreeding might be adapted for rare and endangered | Xiaoping RAO Jian-Xu ZHANG Dingzhen LIU Lin CONG | 2009 | Current Zoology2009，55，1： | 0 |
