Fig. 4From: 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 reproductive organs of Arabidopsis thaliana. Histochemical GUS staining during reproductive development of arabidopsis pST::GUS plants (a to g sorted according to developmental stage). Numbers refer to the corresponding ST gene. a, anther; e, embryo; f, filament; fb, floral bud; fl, flower; o, ovary; p, pollen; s, seed; sg, stigma; si, silique; st, style.
