木质纤维素合成与调控机制:从模式植物到油菜

Lignocellulose synthesis and regulatory mechanisms:from model plants to rapeseed

木质纤维素由木质素、纤维素和半纤维素三者组成,是植物细胞的重要组成成分,能增强植物细胞和组织的机械强度,对于保障植物营养物质运输、茎秆支撑等具有重要意义。而油菜是我国和世界范围内重要的油料作物,具有油用、饲用、菜用、蜜用、观光等多种用途,其木质纤维素也可有效保障植物细胞和组织的机械强度,提高植株的抗倒伏、抗病虫等能力。本文综述了模式植物拟南芥和油菜中木质纤维素合成与调控机制的研究进展,希望模式植物木质纤维素的研究能促进油菜相关研究的深入开展,并对木质纤维素相关研究在油菜中的潜在应用进行了讨论。

Lignocellulose,composing of lignin,cellulose and hemicellulose,is an important component of plant cells.It can enhance the mechanical strength of plant cells and tissues,and is of great significance for ensuring the transport of plant nutrients and stem support.Rapeseed is one of the most significan oil crop in China and the world.It can be used for oil,feeding,vegetables,honey and sightseeing.Lignocellulose can also effectively guarantee the mechanical strength of plant cells and tissues,and improve the resistance to lodging,diseases and insects.The research progress of lignocellulosic synthesis and the regulation mechanism in Arabidopsis thaliana and rapeseed is reviewed.The research of lignocellulosic in Arabidopsis thaliana is expected to promote the further research of rapeseed,and the potential application of the lignocellulosic research in rapeseed is discussed.
