Fig. 1: Nitrogen contents of the leaves and stems of five wild and seven domesticated rice accessions.

Asterisks indicate the leaves’ nitrogen content and stems’ nitrogen content significant differences between wild and domesticated rice based on a two-sided Welch’s t-test, p = 4.28E-08 for roots’ nitrogen content, p = 2.75E-09 for leaves’ nitrogen content, p = 1.59E-08 for steams’ nitrogen content, p = 1.49E-07 for total nitrogen content (n = 3 biological replicates). Data were presented as mean values ± SD. Source data are provided as a Source Data file.
