Fig. 1. Identification and characterization of tgw1.

a Representative images of main tiller spikes from WT or tgw1. Scale bar = 1 cm. b Average length of main spikes from WT and tgw1. n = 11. c–d Comparison of width and length of mature grains from WT or tgw1. Scale bar = 1 cm. e Average grain weight in WT and tgw1. n = 80. f Representative images of grain endodermal cells in WT and tgw1. Scale bar = 100 μm. g Average width of grain endodermal cell in WT (n = 17) and tgw1 (n = 11). h The average area of flag leaves in WT and tgw1 mutant. n = 10. i Leaf epidermal cells in WT or tgw1 mutant. Scale bar = 100 μm. j Average chlorophyll units in flag leaves from WT and tgw1 mutant. n = 10. Data in e are represented as boxplots. The boxplots indicate median (middle line), 25^th, 75^th percentile (box), and 5^th and 95^th percentile (whiskers) as well as outliers (single points). Data in b, e, g, h, and j are represented as mean ± SEM, and p values are indicated by two-tailed unpaired t test. Results in f and i are representative of three independent samples. Source data are provided as a Source Data file.
