Fig 2. top1α-10 and upf1-1 exhibit a parent-of-origin effect on diploidy crosses.
(A) Representative seeds from reciprocal crosses between WT and top1α-10. Scale bars, 0.5 mm. (B) Representative seeds from reciprocal crosses between WT and upf1-1. Scale bars, 0.5 mm. (C, D) Parent-of-origin effect of top1α-10 (C) and upf1-1 (D) pertaining to seed size. (E) Histograms of the size distributions of seeds produced by top1α-10-related testcrosses (left panels) and upf1-1-related testcrosses (left panels). The distribution curves were determined by kernel-density estimation. The data underlying this figure are included in S1 Data. WT, wild-type plants.
