Fig. 3From: 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 vegetative organs of Arabidopsis thaliana plants. Histochemical GUS staining in vegetative organs (a, roots; b-d, aerial parts) of 10- to 24-d-old pST::GUS transgenic plants. Numbers refer to the corresponding ST gene. c, cotyledon; er, emerging root; fs, floral stem; h, hypocotyl; l, leaf; r, root; ra, root apex; s, stoma. The blue colour and the arrows indicate the zones with GUS activity driven by pST Back to article page
