| Research Abstract |
Germination of Arabidopsis seeds is regulated by light through the photoreceptor phytochrome. Previous studies have shown that PIL5, a phytochrome-interacting protein, plays a role in modulating the levels of plant hormones, such as gibberellin and abscisic acid, in imbibed seeds. To better understand the molecular mechanisms for light-dependent seed germination, we have identified target genes of PIL5 and characterized new gibberellin-related genes.
