Abstract

Soybean [Glycine max (L.) Merr.] is an important crop used for human consumption, animal feed and biodiesel fuel. Wering time and maturity significantly affect soybean grain yield. In Arabidopsis thaliana, miR156 has been proposed to regulate the transition from the juvenile to the adult phase of shoot development, which is accompanied by changes in vegetative morphology and an increase in reproductive potential. However, the molecular mechanisms underlying miR156 function in soybean flowering remain unknown. Here, we report that the overexpression of GmmiR156b delays flowering time in soybean. GmmiR156b may target SPL orthologs and negatively regulate GmSPLs, thereby delaying flowering in soybean under LD and natural conditions. GmmiR156b down-regulates several known flowering time regulators in soybean, such as GmAP1 (a, b, c), GmLFY2, GmLFY2, GmFULs, GmSOC1s, GmFT5a, and GmmiR172. These data show that a similar miR156-SPL regulatory module was conserved in the soybean flowering pathway. However, GmFULs, GmSOC1a and GmSOC1b were significantly suppressed under LD conditions but not under SD conditions, which is different in Arabidopsis that these genes were down-regulated irrespective of photoperiod. In addition, GmmiR156b was...Continue Reading
