DELLA expression is differentially localized in tissues of pistils and fruits.
DELLA expression was analyzed using transcriptional fusion lines pGAI:GUS, pRGA:GUS, and pRGL1:GUS (see Experimental procedures), and mutant line rgl2-5 for RGL2.
(a) DELLA expression in whole pistils at anthesis. Scale bar represents 500 μm.
(b) Expression in cross-sections of pistils and ovules at anthesis (left and middle panels), and seeds at 1 or 2 dpa (right panels). o, ovule; r, replum; s, septum-transmitting track; v, valve, en, endocarp; mi, micropyle; es, embryo sac; cha, chalaza. Scale bar represents 50 μm.
