Enhancing seed yield and nitrogen use efficiency of Brassica napus L.under low nitrogen by overexpression of G-proteins from Arabidopisis

[Objective]Heterotrimeric G-proteins,composed of Gα,Gβ,and Gγ subunits,are involved in the regulation of a variety of signaling pathways in plants.Osdep1(Gγ subunit-encoded protein)of rice and TaNBP1(Gβ subunit-encoded protein)of wheat are homologs of Arabidopsis AGG3 and AGB1,respectively,which are regulators of grain size and also involved in nitrogen responses.However,the function of Arabidopsis G-proteins in nitrogen utilization under different nitrogen …查看全部>>
