Effects of drought stress on endosperm development at proteomic level. A transcriptional regulatory network in the endosperm development shown (modified from Dai et al. 2021). The Log2 (fold change) was calculated for WW conditions relative to WS. SE: starchy endosperm, AL: aleurone, BETL: basal endosperm transfer layer, ESR: embryo-surrounding region, EAS: endosperm adjacent to scutellum. WW: well-watered; WS: water-stressed. Asterisks designate statistical (using Student’s t-test) significance P < 0.01
