Flowers into shoots: Photo and hormonal control of a meristem identity switch in Arabidopsis

摘要

Little is known about the signals that govern the network of meristem and organ identity genes that control flower development. In Arabidopsis, we can induce a hetero- chronic switch from flower to shoot development, a process known as floral meristem reversion, by manipulating photo- period in the floral homeotic mutant agamous and in plants heterozygous for the meristem identity gene leafy.
