Fig. 4.

Root, etiolated hypocotyl, and root hair phenotyping in the wild type, knock-out, and overexpression lines of AtPRPL1. (a) Root length, (b) etiolated hypocotyl length, and (c) root hair length of wild type, knock-out, and overexpression plants. Asterisks refer to significant changes compared with the corresponding wild types (the wild type and lines that are statistically compared with it are presented in the same greyscale). Data shown are the average of three representative biological replicates having at least 15 seedlings; error bars represent the SE. Student’s t-test, P<0.05.
