Spatial and developmental analysis of reporter gene expression KDSA2::GUS in Arabidopsis thaliana plants. GUS staining was performed using the AtkdsA2-V mutant plants (KDSA2-V::GUS), transformants with a T-DNA harbouring the cloned KDSA2 promoter upstream of the uidA coding region (KDSA2::GUS) to confirm the specificity expression and transformants harbouring 35S::GUS as a control of GUS staining. (a) Four-leaf plantlets; (b) young leaves; (c) hydathodes of young leaves; (d) fully developed flowers; (e) dissected siliques.
