The barley (Hordeum vulgare) gene Hv.AGP.S.1 produces two different transcripts encoding small subunits (SSUs) of ADP-glucose pyrophosphorylase (AGPase). It was shown previously that one of these transcripts, Hv.1a, encodes the cytosolic SSU in the endosperm. It is shown here that the other transcript produced from Hv.AGP.S.1, Hv.1b, encodes a plastidial SSU that is required for >90% of the AGPase activity in the leaves. Thus, both of the alternative transcripts encoded by Hv.AGP.S.1 are… CONTINUE READING
