Fig. 2From: Three members of Medicago truncatula ST family are ubiquitous during development and modulated by nutritional status (MtST1) and dehydration (MtST2 and MtST3)Activity of Medicago truncatula pST1, pST2 and pST3 in Arabidopsis thaliana seedlings. Histochemical GUS staining in transgenic pST::GUS seedlings at 3- (a, b) and 10-d-old (c, d) grown in darkness (a, c) or light (b, d). Numbers refer to the corresponding ST gene. c, cotyledon; h, hypocotyl; l, leaf; r, root; ra, root apex. The blue colour and the arrows indicate the zones with GUS activity driven by pST Back to article page
