| 1 | The nodulation and nyctinastic leaf movement is orchestrated by clock gene LHY in Medicago truncatula显示文摘As sessile organisms,plants perceive,respond,and adapt to the environmental changes for optimal growth and survival.The plant growth and fitness are enhanced by circadian clocks through coordination of numerous biological events.In legume species,nitrogen-fixing root nodules were developed as the plant organs specialized for symbiotic transfer of ni-trogen between microsymbiont and host.Here,we report that the endogenous circadian rhythm in nodules is regulated by MtLHY in legume species Medicago truncatula.Loss of function of MtLHY leads to a reduction in the number of nodules formed,resulting in a diminished ability to assimilate nitrogen.The operation of the 24-h rhythm in shoot is further influenced by the availability of nitrogen produced by the nodules,leading to the irregulated nyctinastic leaf movement and reduced biomass in mtlhy mutants.These data shed new light on the roles of MtLHY in the orchestration of circadian oscillator in nodules and shoots,which provides a mechanistic link between nodulation,nitrogen assimilation,and clock function. | Yiming Kong Lu Han Xiu Liu Hongfeng Wang Lizhu Wen Xiaolin Yu Xiaodong Xu Fanjiang Kong Chunxiang Fu Kirankumar S.Mysore Jiangqi Wen Chuanen Zhou | 2020 | Journal of Integrative Plant Biology2020，62，12： | 4 |
| 2 | AGAMOUS AND TERMINAL FLOWER controls floral organ identity and inflorescence development in Medicago truncatula显示文摘Angiosperms integrate a multitude of endogenous and environmental signals to control floral development,thereby ensuring reproductive success.Here,we report the identification of AGAMOUS AND TERMINAL FLOWER(AGTFL),a novel regulator of floral development in Medicago truncatula.Mutation of AGTFL led to the transformation of carpels and stamens into numerous sepals and petals and altered primary inflorescence identity.AGTFL encodes a nucleus-localized proteincontaining a putative Myb/SANT-like DNA-binding domain and a PKc kinase domain.Molecular and genetic analyses revealed that AGTFL regulates the transcription of MtAGs and MtTFL1 to control floral organ identity and inflorescence development. | Butuo Zhu Hui Li Yifeng Hou Pengcheng Zhang Xiuzhi Xia Na Wang Hui Wang Kirankumar S.Mysore Jiangqi Wen Yanxi Pei Lifang Niu Hao Lin | 2019 | Journal of Integrative Plant Biology2019，61，8： | 2 |

| 6 | From model to alfalfa:Gene editing to obtain semidwarf and prostrate growth habits显示文摘Alfalfa(Medicago sativa L.)is a nutritious forage crop with wide ecological adaptability.The molecular breeding of alfalfa is restricted by its heterozygous tetraploid genome and the difficult genetic manipulation process.Under time and resource constraints,we applied a more convenient approach.We investigated two MtGA3ox genes,MtGA3ox1 and MtGA3ox2,of Medicago truncatula,a diploid legume model species,finding that MtGA3ox1 plays a major role in GA-regulated plant architecture.Mutation of neither gene affected nitrogenase activity.These results suggest that MtGA3ox1 can be used in semidwarf and prostrate alfalfa breeding.Based on the M.truncatula MtGA3ox1 sequence,MsGA3ox1 was cloned from alfalfa,and two knockout targets were designed.An efficient CRISPR/Cas9-based genome editing protocol was used to generate msga3ox1 mutants in alfalfa.We obtained three lines that carried mutations in all four alleles in the T0 generation.Fifteen clonal plants were vegetatively propagated from each transgenic line using shoot cuttings.The plant height and internode length of msga3ox1 null mutants were significantly decreased.The number of total lateral branches,leaf/stem ratio and crude protein content of aerial plant parts of msga3ox1 mutants were significantly increased.Thus,we obtained semi-dwarf and prostrate alfalfa by gene editing. | Lihua Zheng Jiangqi Wen Jinling Liu Xiangzhao Meng Peng Liu Na Cao Jiangli Dong Tao Wang | 2022 | The Crop Journal2022，10，4： | 0 |
| 7 | Medicago truncatula resources to study legume biology and symbiotic nitrogen fixation显示文摘Medicago truncatula is a chosen model for legumes towards deciphering fundamental legume biology,especially symbiotic nitrogen fixation.Current genomic resources for M.truncatula include a completed whole genome sequence information for R108 and Jemalong A17 accessions along with the sparse draft genome sequences for other 226 M.truncatula accessions.These genomic resources are complemented by the availability of mutant resources such as retrotransposon(Tnt1)insertion mutants in R108 and fast neutron bombardment(FNB)mutants in A17.In addition,several M.truncatula databases such as small secreted peptides(SSPs)database,transporter protein database,gene expression atlas,proteomic atlas,and metabolite atlas are available to the research community.This review describes these resources and provide information regarding how to access these resources. | Raja Sekhar Nandety Jiangqi Wen Kirankumar S.Mysore | 2023 | Fundamental Research2023，3，2： | 0 |
| 8 | Comparative transcriptome analyses reveal that the MsNST1 gene affects lignin synthesis in alfalfa(Medicago sativa L.)显示文摘As the second most abundant natural polymer,accounting for approximately 30%of the organic carbon in the biosphere,lignin plays an essential role in plant development.However,a high lignin content affects the nutritional quality of alfalfa(Medicago sativa L.),the most widely cultivated perennial legume forage crop.Histological analysis indicated that G-lignin and S-lignin were present in the stem,leaf,and petiole of alfalfa,and the deposition of lignin increased gradually in descending internodes.Neutral detergent fiber(NDF),acid detergent fiber(ADF),and acid detergent lignin(ADL)contents continually increased from the top to the bottom of the stem,and ADL content showed a similar trend in leaves.Alfalfa leaves and stems from five different nodes(1,2,4,6,and 8)were used as materials to investigate molecular regulatory mechanisms in lignin synthesis by RNA sequencing.Respectively 8074 and 7752 differentially expressed genes(DEGs)were identified in leaves and stems,and 1694 DEGs were common to the two tissues.‘‘Phenylpropanoid biosynthesis”was the most enriched pathway in both leaves and stems,and 134 key regulatory genes in lignin synthesis were identified by a weighted gene co-expression network analysis.The NAC family transcription factor MsNST1 gene was highly expressed in old leaf and stem tissues.The deposition pattern of G-and S-lignin differed among M.truncatula wild-type,nst1 mutants,and overexpression lines,and the transcription levels of lignin synthesis genes such as HCT,F5H,and COMT in these three materials also differed.These results suggest that MsNST1 affects lignin synthesis in alfalfa.These findings provide a genetic basis and abundant gene resources for further study of the molecular mechanisms of lignin synthesis,laying a foundation for low-lignin alfalfa breeding research. | Qiang Zhou Pei Mao Dong Luo Xutian Chai Hao Deng Qiangen Fang Longfa Fang Zhibiao Nan Jiangqi Wen Zhipeng Liu | 2022 | The Crop Journal2022，10，4： | 0 |
| 9 | The role of Class Ⅱ KNOX family in controlling compound leaf patterning in Medicago truncatula显示文摘Compound leaf development requires the coordination of genetic factors, hormones, and other signals. In this study, we explored the functions of Class Ⅱ KNOTTED-like homeobox(KNOXII)genes in the model leguminous plant Medicago truncatula. Phenotypic and genetic analyses suggest that Mt KNOX4, 5 are able to repress leafet formation, while Mt KNOX3, 9, 10 are not involved in this developmental process. Further investigations have shown that Mt KNOX4 represses the CK signal transduction, which is downstream of Mt KNOXⅠ-mediated CK biosynthesis. Additionally,two boundary genes, FUSED COMPOUND LEAF1(orthologue of Arabidopsis Class M KNOX) and NO APICAL MERISTEM(orthologue of Arabidopsis CUP-SHAPED COTYLEDON), are necessary for Mt KNOX4-mediated compound leaf formation.These findings suggest, that among the members of Mt KNOXⅡ, Mt KNOX4 plays a crucial role in integrating the CK pathway and boundary regulators,providing new insights into the roles of Mt KNOXⅡ in regulating the elaboration of compound leaves in M. truncatula. | Xiao Wang Juanjuan Zhang Maofeng Chai Lu Han Xiaohua Cao Jing Zhang Yiming Kong Chunxiang Fu Zeng‐Yu Wang Kirankumar SMysore Jiangqi Wen Chuanen Zhou | 2023 | Journal of Integrative Plant Biology2023，65，10： | 0 |
| 10 | HCN evolution and changes of activity of P-cyanoalanine synthase in potato tubers显示文摘DORMANCY-BREAKING potato tubers will germinate at suitable temperatures. It is a commonknowledge that germinating potato tubers are toxic. It has also been known that the seriouslytoxic compound named solanine, which exists abundantly in the green-turning parts of thepotato tubers, is the main cause of this toxicity. But it is still unknown what causes food poi-soning after eating the parts of dormancy-breaking potato tubers that have not turned green.In a previous report we have shown that the operation of the cyanide-resistant respiration path-way during aging process of the slices from dormancy-breaking potato tubers is stronger | WEN Jiangqi, LIANG Wusheng and LIANG Houguo1 Laboratory of Plant Physiology, Lanzhou University, Lanzhou 730000, China 2.
