Overexpression of a soybean YABBY gene, GmFILa, causes leaf curling in Arabidopsis thaliana.

ABSTRACT:

Background

YABBY genes play important roles in the growth and polar establishment of lateral organs such as leaves and floral organs in angiosperms. However, the functions of YABBY homologous genes are largely unknown in soybean.

Results

In this study, we identified GmFILa encoding a YABBY transcription factor belonging to FIL subfamily. In situ mRNA hybridization analysis indicated that GmFILa had specific expression patterns in leaf as well as in flower bud primordia. Ectopic expression of GmFILa in Arabidopsis thaliana altered the partial abaxialization of the adaxial epidermises of leaves. Besides, GmFILa transgenic plants also exhibited longer flowering period and inhibition of shoot apical meristem (SAM) development compared to the wild type plants. Digital expression
