    植物维管组织形态建成的分子调控机制

    Molecular regulation mechanism of vascular pattern formation in plant

    • 摘要: 在植物个体发育过程中,维管组织形态建成受多种外源及內源因子的共同影响。研究表明:植物激素、CLE 短肽信号分子、多种转录因子、热精胺、NO 等均在维管组织形态建成中发挥重要调控作用。AUX、CTK、ET、BRs、 GA 等共同参与调节原形成层与形成层细胞的增殖和分化;CLE 短肽信号分子可促进(原)形成层细胞增殖并抑制 木质部分化;HD-ZIP Ⅲ基因家族,KAN、NAC、MYB 转录因子及木质形成素与木质部、韧皮部的布局排列及发育相 关;热精胺与NO 影响着木质部细胞的分化。多种调节因子相互关联构建形成复杂的调控网络,作用于植物维管组 织的形态建成过程。

       

      Abstract: Vascular tissue morphogenesis is influenced by many kinds of exogenous and endogenous factors jointly during plant ontogeny. It was found that plant hormones, CLE peptide signaling molecules, different transcription factors,thermospermine and NO played important regulating roles in vascular tissue morphogenesis. AUX, CTK, ET, BRs, GA, and other plant hormones jointly regulated proliferation and differentiation process of the procambium and cambium cell; CLE peptides signaling molecules promoted (pro-) cambium cell proliferation and inhibited xylem differentiation; HD-ZIP Ⅲgene families, KAN, NAC, MYB transcription factors, and xylogen were greatly associated with both the arrangement and development of xylem and phloem; thermospermine and NO affected the xylem cells' differentiation. A complex regulating network consisting of various regulatory factors played a key role in the process of plant vascular tissue morphogenesis.
