摘要: |
以金鱼草和拟南芥菜为例,介绍近年高等植物花发育的研究进展。TFL和CEN基因具有维持花序分生组织特性的功能;DCLV1基因在营养型分生组织向生殖型分生组织转化中起调节作用; LEY、AP1、CAL和FLO控制花分生组织形态特征;AP1/SQUA、AP2作用于A功能区,控制萼片和花瓣的发育;AP3/DEF、PI/GLO执行B功能控制花瓣和雄蕊的发育;AG/PLE对应于C功能区控制雄蕊和心皮的发育;A、B、C三个功能区共同作用控制整个花器官的结构。 |

Progress of Flower Development in Higher Plants |

Abstract: |
The article reviews the recent progress of flower development in Antirrhinum and Arabidopsis.TFL gene and CEN gene have the similar roles in controlling of
inflorescence architecture. LFY, FLO,API and CAL are members of a general class of
genes needed to confer floral identity.Wild type flower contains three genetic functions
in whorl 1-4 in combination A,AB,BC, and C conferring identities speal, petal, stamen,
carpel respectively.Each genetic function comprises different homeotic genes. |
