'Florigen' enters the molecular age: long-distance signals that cause plants to flower

Trends Biochem Sci. 2000 May;25(5):236-40. doi: 10.1016/s0968-0004(00)01542-5.


The transition from vegetative to reproductive growth is a critical event in the life cycle of plants. Previous physiological studies have deduced that hormone-like substances mediate this important transition but the biochemical nature of the putative signaling molecules has remained elusive. Recent molecular and genetic studies of key flowering-time genes offer new approaches to understanding the mechanisms underlying the initiation of flowering.
