| 1 | 植物TCP转录因子的作用机理及其应用研究进展显示文摘TCP转录因子是一类植物特有蛋白,含有保守的TCP domain,其中由60个氨基酸组成的b HLH结构是结合DNA和蛋白互作所必需的。TCP转录因子由于其广泛参与调控植物的生长发育过程(如分枝、株高、叶型、花型等)而备受关注。最近有报道显示,TCP转录因子在植物逆境胁迫应答中(如低温和高盐)同样发挥重要作用。TCP蛋白参与多种信号转导途径(如油菜素内酯、茉莉酸、赤霉素、细胞分裂素等),可能是连接生长发育和介导胁迫响应的一个交叉点。本文从分子生物学角度,系统综述了植物TCP转录因子的作用机理及其在激素应答、发育调控及环境胁迫响应等过程中的功能,以期为基因工程方法改良作物生长模式和抗性提供参考。 | 冯志娟 徐盛春 刘娜 张古文 胡齐赞 龚亚明 | 2018 | 植物遗传资源学报2018，19，1： | 13 |

| 3 | Functional Diversity of CYCLOIDEA-like TCP Genes in the Control of Zygomorphic Flower Development in Lotus japonicus显示文摘CYCLOIDEA (CYC)-like TCP genes play key roles in dorsoventral differentiation of zygomorphic flowers in Papilionoideae legumes. In this study, we analyzed the kew mutants whose flowers lost lateral identity, and investigated the diverse functions of three LjCYC genes during zygomorphic flower development in the model legume Lotus japonicus. We showed that kew1 and kew3 are allelic mutants of LjCYC3, a CYC-like TCP gene. Through transgenic experiments, it was shown that LjCYC1 possesses dorsal activity similar to LjCYC2, and that LjCYC3 alone is sufficient to confer lateral activity, and an epistatic effect between dorsal and lateral activities was identified. Sequence analysis revealed a striking alteration at the 3 end of the LjCYC3 open reading frame (ORF) in comparison with those of LjCYC1 and LjCYC2 ORFs. Furthermore, it was found that LjCYC proteins could interact with each other and possess different activities by means of a transcriptional activity assay. Our data demonstrate that the sequence variation and the subsequent alteration of protein property play important roles in the functional diversity of different LjCYC genes in controlling zygomorphic flower development in Lotus japonicus. | Shilei Xu Yonghai Luo Zhigang Cai Xiangling Cao Xiaohe Hu Jun Yang Da Luo | 2013 | Journal of Integrative Plant Biology2013，55，3： | 6 |
| 4 | Roles of miR319-regulated TCPs in plant development and response to abiotic stress显示文摘Elaborate regulation of gene expression is required for plants to maintain normal growth,development,and reproduction.MicroRNAs(miRNAs)and transcription factors are key players that control gene expression in plant regulatory networks.The TEOSINTE BRANCHED1/CYCLOIDEA/PROLIFERATING CELL FACTOR(TCP)family comprises plantspecific transcription factors that contain a conserved TCP domain of 59 amino acids.Some members of this family are targeted by miR319,one of the most ancient and evolutionarily conserved miRNAs in plants.Accumulating evidence has revealed that miR319-regulated TCP(MRTCP)genes participate extensively in plant development and responses to environmental stress.In this review,the structural characteristics and classifications of TCP transcription factors and the regulatory relationships between TCP transcription factors and miRNAs are introduced.Current knowledge of the regulatory functions of MRTCP genes in multiple biological pathways including leaf development,vascular formation,flowering,hormone signaling,and response to environmental stresses such as cold,salt,and drought is summarized.This review will be beneficial for understanding the roles of the MRTCP-mediated regulatory network and its molecular mechanisms in plant development and stress response,and provides a theoretical basis for plant genetic improvement. | Yujie Fang Yuqian Zheng Wei Lu Jian Li Yujing Duan Shuai Zhang Youping Wang | 2021 | The Crop Journal2021，9，1： | 4 |

| 6 | 牡丹TCP家族基因的鉴定与生物信息学分析显示文摘TCP(Teosinte branched1/Cincinnata/proliferating cell factor)家族基因是植物特有的一类转录因子,在植物生长发育的过程中具有重要的调控作用。本研究从牡丹转录组数据中鉴定出18个TCP基因,分子量在18978.32~51789.56 Da之间,等电点在5.81~9.45之间,TCP家族成员亚细胞定位预测均在细胞核中。牡丹TCP结构域中保守氨基酸的分类与拟南芥相似,系统发育分析结果表明,牡丹TCP蛋白分为两大类,ClassⅠ包含10个TCP成员,ClassⅡ包含8个TCP成员。MEME分析结果显示,在牡丹TCP蛋白中发现了15个保守结构域,其中motif 1为TCP结构域,在所有TCP成员中都存在。同时,对牡丹TCP基因在芽、叶、花瓣、花斑、雄蕊、雌蕊和种子7个组织中的转录水平进行了分析。本研究对牡丹TCP家族基因进行了系统的分析,为进一步开展牡丹功能基因研究及分子育种提供了科学依据。 | 张延召 罗新 李会云 段旭佳 张妍 | 2022 | 分子植物育种2022，20，1： | 2 |
| 7 | Petal Development in Lotus japonicus显示文摘Previous studies have demonstrated that petal shape and size in legume flowers are determined by two separate mechanisms,dorsoventral (DV) and organ internal (IN) asymmetric mechanisms,respectively.However,little is known about the molecular mechanisms controlling petal development in legumes.To address this question,we investigated petal development along the floral DV axis in Lotus japonicus with respect to cell and developmental biology by comparing wild-type legumes to mutants.Based on morphological markers,the entire course of petal development,from initiation to maturity,was grouped to define 3 phases or 13 stages.In terms of epidermal micromorphology from adaxial surface,mature petals were divided into several distinct domains,and characteristic epidermal cells of each petal differentiated at stage 9,while epidermal cells of all domains were observed until stage 12.TCP and MIXTA-like genes were found to be differentially expressed in various domains of petals at stages 9 and 12.Our results suggest that DV and IN mechanisms interplay at different stages of petal development,and their interaction at the cellular and molecular level guides the elaboration of domains within petals to achieve their ideal shape,and further suggest that TCP genes determine petal identity along the DV axis by regulating MIXTA-like gene expression. | Lin Weng Zhaoxia Tian Xianzhong Feng Xin Li Shilei Xu Xiaohe Hu Da Luo Jun Yang | 2011 | Journal of Integrative Plant Biology2011，53，10： | 1 |
