摘　　要：拟南芥是最重要的模式植物之一.近期,拟南芥主茎与花柄之间水平连接的特殊器官——Cantil(中文命名为:花梗臂)被再次报道.该研究对花梗臂的形态、结构进行详细介绍,并利用拟南芥不同生态型以及突变体对花梗臂的产生条件、发育调控机制做了深入的研究.结果表明,MYB13、RTFL/DVL家族成员、ERECTA、染色体非整倍性以及短日照均能促进花梗臂的形成;而FT、异源三聚体G蛋白复合体、长日照等因素都会抑制花梗臂的形成.需要强调的是,花梗臂的形成又与植物健康状态密切相关,作为一个略显神秘的新器官,花梗臂的发生、发育的机制还亟待深入研究.Arabidopsis thaliana is one of the most important model plants.Recently,cantil,a special organ of Arabidopsis for the horizontal connection between the main stem and petiole has been rediscovered and deeply reported.In this review,the morphology and structure of cantil were introduced in detail,and the production conditions and development regulation mechanism of cantil were discussed by using different ecotypes and mutants of Arabidopsis.The results showed that MYB13,RTFL/DVLfamily members,ERECTA,aneuploidy,and short-day could promote the formation of cantil.However,FT,heterotrimeric G protein complex,long-day could inhibit the formation of cantil.It should be emphasized that the formation of the cantil was highly related to plant health.As a mysterious new organ,the mechanism of the occurrence and development of the cantil still needs to be further studied.
