Abstract

Plant morphogenesis largely depends on the orientation and rate of cell division and elongation, and their coordination at all levels of organization. Despite recent progresses in the comprehension of pathways controlling division plane determination in plant cells, many pieces are missing to the puzzle. For example, we have a partial comprehension of formation, function and evolutionary significance of the preprophase band, a plant-specific cytoskeletal array involved in premitotic setup of the division plane, as well as the role of the nucleus and its connection to the preprophase band of microtubules. Likewise, several modeling studies point to a strong relationship between cell shape and division geometry, but the emergence of such geometric rules from the molecular and cellular pathways at play are still obscure. Yet, recent imaging technologies and genetic tools hold a lot of promise to tackle these challenges and to revisit old questions with unprecedented resolution in space and time.

植物细胞分裂的时空调控
植物形态发生在很大程度上取决于细胞分裂和伸长的方向和速度,以及它们在各级组织中的协调。尽管最近在理解控制植物细胞分裂平面决定的途径方面取得了进展,但仍有许多谜题尚未解开。例如,我们已经部分了解了分裂前带的形成、功能和进化意义,分裂前带是植物特有的细胞骨架阵列,参与分裂平面的有丝分裂前设置,我们还了解了细胞核的作用及其与微管分裂前带的连接。同样,一些建模研究指出,细胞形状与分裂几何形状之间存在密切关系,但这些几何规则是如何从分子和细胞途径中产生的,目前仍不清楚。然而,最新的成像技术和基因工具有望解决这些难题,并以前所未有的空间和时间分辨率重新审视老问题。
