Title : Cell cycle regulation of the initial division events during de novo root organogenesis in arabidopsis

Abstract:

Unlike animals, plants have remarkable abilities to regenerate and form an entire plant body from various tissues or organs, or even from a single somatic cell. Among the different types of plant regeneration, de novo organogenesis, in which adventitious roots and shoots form from wounded or detached plant tissues or organs, is frequently used in basic research. Previous researches have revealed some basic mechanisms underlying de novo root organogenesis in arabidopsis, among which the dispensable cell fate transition events can be represented by the expression of WOX11, WOX5 and LBD16. However, previous theories cannot illustrate how the initial cell division events are regulated. As is known, proper pattern of the very first division is absolutely important for the regeneration of adventitious roots, and our work fucusing on cell cycle regulation during de novo root organogenesis may give some new insights into the molecular basic of de novo root organogenesis in arabidopsis. Here, we will make a brief introduction of the mechanism underlying the initial cell division events from three aspects as follows: First is about the pattern and progress of the initial cell division of ‘competent cells’. Secondly, we will discuss about the relationship between cell fate transition and cell cycle regulation during the initial cell division events. At last, we will make a summary of the already known data underlying regulation of the initial cell division events and get a preliminary conclusion. This presentation will provide new insights into plant regeneration benefits related research; Our improved molecular model underlying de novo root organogenesis may better guide agricultural industry.
