Loss of Function of Ferredoxin2 Can Promote Flowering in Arabidopsis thaliana
摘要
Abstract
In Arabidopsis thaliana, the red and far-red light photoreceptors phytochromes (PHYs) act to involve in regulating flowering.Phytochromobilin synthase (HY2) synthesizes the open chain tetrapyrrole chromophore which is essential to the light-sensing function of phytochromes , and it is a member of the ferredoxin-dependent bilin reductases (FDBRs).Here, we found a Ds-T-DNA insertion line of Arabidop-sis thaliana for the gene encoding the most major ferredoxin (Fd2, At1g60950), which can promote flowering in the process of growth both under long-day and short-day conditions.In this report we show that loss of AtFd2c an promote flowering, AtFd2 interacts with AtHY2 in the chloroplast, and Fd2-KO mutants are impaired in the responses mediated by phytochromes .Together, these results implicate that loss of AtFd2 may promote flowering by impairing the physiology function of phytochromes .关键词
