GmFT2a polymorphism and maturity diversity in soybeans.

ABSTRACT:

Background

Soybean is a short-day crop of agricultural, ecological, and economic importance. The sensitive photoperiod responses significantly limit its breeding and adaptation. GmFT2a, a putative florigen gene with different transcription profiles in two cultivars (late-maturing Zigongdongdou and early-maturing Heihe 27) with different maturity profiles, is key to flowering and maturation. However, up to now, its role in the diverse patterns of maturation in soybeans has been poorly understood.

Methods

Eighty varieties, including 19 wild accessions, covering 11 of all 13 maturity groups, were collected. They were planted in pots and maintained under different photoperiodicity conditions (SD, short day; LD, long day; and ND, natural day). The day to first flowering was recor
