TaABCC13 silencing affects grain filling and spike characteristics. (A) Representative images of the developing wheat caryopsis at the onset of flowering for C306 (control) and representative TaABCC13:RNAi lines. (B) Decreased length of spikes upon maturation for control (C306) and RNAi lines. (C) Detailed grain filling at the spike head on control (C306) and RNAi lines. (D) Representative images of seeds collected from C306 (control) and RNAi lines. (E) Total spikelet counts from RNAi lines as compared to C306. (F) Seed count from the primary spikes of the C306 and RNAi lines. Observations presented here were collected from T₄ progenies that were consistent with the non-segregating lines of the T₃ generation. The data in (E) and (F) are means ±SD. Ten spikes from each TaABCC13:RNAi line (only from the primary tiller) and the respective controls were considered for above observations. ** indicates significant differences at P<0.05 (t-test).
