Overexpression of the GmGAL2 Gene Accelerates Flowering in Arabidopsis

A soybean MADS box gene GmGAL2 (Glycine max AGAMOUS Like 2), a homolog of AGL11/STK, was investigated in transgenic Arabidopsis lines. Ectopic expression of GmGAL2 in Arabidopsis enhanced flowering, under both long-day and short-day conditions, by promoting expression of key flowering genes, CONSTAN...

Descripción
Sumario:A soybean MADS box gene GmGAL2 (Glycine max AGAMOUS Like 2), a homolog of AGL11/STK, was investigated in transgenic Arabidopsis lines. Ectopic expression of GmGAL2 in Arabidopsis enhanced flowering, under both long-day and short-day conditions, by promoting expression of key flowering genes, CONSTANS (CO) and FLOWERING LOCUS T (FT), and lowering expression of floral inhibiter FLOWERING LOCUS C (FLC). Moreover, frequency of silique pod set was also lower in transgenic compared to control Arabidopsis plants. RT-PCR results revealed that GmGAL2 was primarily expressed in the flowers and pods of soybean plants, GmGAL2 expressed higher in SD than LD in soybean.
