Critical plant gene takes unexpected detour that could boost biofuel yields
Blog, The Plant Cell, The Plant Cell: News
OAK RIDGE, Tenn., June 15, 2018 - For decades, biologists have believed a key enzyme in plants had one function--produce amino acids, which are vital to plant survival and also essential to human diets.
But for Wellington Muchero, Meng Xie and their colleagues, this enzyme does more than advertised.…
