Research identifies protein that signals flowering in squash plants

[B]This research provides some of the most solid evidence to date that FT protein acts as a florigenic signal[/B]
The length of the day relative to night, or photoperiod, is a strong determining factor for the induction of flowering in many plant species. Short day (SD) plants require a short day length (or more precisely, a long night) in order to flower. These are plants that flower as the days grow shorter, such as in the fall in temperate regions. Long day (LD) plants will flower when nights are short (and days are long), and typically flower in late spring or early summer. SD crops include rice and maize, and LD crops include wheat, barley, oats and peas. Day-neutral plants will flower under either long or short days. In addition to its fundamental importance in basic plant biology, understanding and manipulating the photoperiodic control of flowering time is an important objective in crop breeding and development programs, because it can aid in optimizing crop yields and other traits for local environmental conditions.
