Ectopic expression of a WRKY homolog from Glycine soja alters flowering time in Arabidopsis.

Flowering is a critical event in the life cycle of plants; the WRKY-type transcription factors are reported to be involved in many developmental processes sunch as trichome development and epicuticular wax loading, but whether they are involved in flowering time regulation is still unknown. Within t...
