Expression of HvSPL genes during growth phase transition in barley. (A) Transcript abundance of HvSPL13 and (B) HvSPL6 at vegetative (10 days) and reproductive (75 days) phases. (C) Spike architecture of barley mir172 mutant and wild type GP. A single 3.6 kb Ds insertion in mir172 mutant was previously identified by Brown and Bregitzer, 2011. This mutant possesses abnormal spike at both apical region (glumes were changed to florets) and basal region (abnormal branched phenotype). (D–H) Expression of HvSPL3, 13, 15, 23 and AP2 genes in the spike of barley mir172 mutant and wild type GP. Transcript abundance was measured by qRT-PCR.
