植物微管(MTs)在整个细胞周期中形成高度动态和独特的阵列,是细胞和器官形态发生所必需的。大量的微管相关蛋白(MAPs),包括保守的和植物特异性的,确保了mt对内部和外部信号的动态响应。MAP215家族MT聚合酶/成核因子和MT切断酶katanin是真核生物中最保守的map。最近的研究揭示了微管组织1 (MOR1), MAP215的拟南芥同源物,和KATANIN 1 (KTN1), KATANIN的催化亚基之间意想不到的功能和物理相互作用。在这篇综述中,我们简要介绍了MOR1和katanin在细胞形态发生和植物生长发育中的功能和调控。
ABSTRACT Plant microtubules (MTs) form highly dynamic and distinct arrays throughout the cell cycle and are essential for cell and organ morphogenesis. A plethora of microtubule associated-proteins (MAPs), both conserved and plant-specific, ensure the dynamic response of MTs to internal and external cues. The MAP215 family MT polymerase/nucleation factor and the MT severing enzyme katanin are among the most conserved MAPs in eukaryotes. Recent studies have revealed unexpected functional and physical interactions between MICROTUBULE ORGANIZATION 1 (MOR1), the Arabidopsis homolog of MAP215, and KATANIN 1 (KTN1), the catalytic subunit of katanin. In this minireview, we provide a short overview on current understanding of the functions and regulations of MOR1 and katanin in cell morphogenesis and plant growth and development.
