Expression of GRXS17 in Arabidopsis plants. A and B, Western analysis of GRXS17 abundance. A, Western-blot analysis in flowers from wild-type and grxS17 plants and organs of wild-type plants grown under standard conditions (20 µg per lane). The Rubisco Large Subunit (LSU) appears as a light-gray background band in the grxS17 lane. B, Floral bud; F, flower; ML, mature leaf; OL, old leaf; R, root from adult plant; S, stem from bolting plant; WT, wild type; YL, young leaf. B, Loading controls: Coomassie Blue-stained gels (50-kD region). C to F, RNA in situ hybridization. Longitudinal sections of wild-type meristem inflorescences (C and D) and flower buds (E and F). Hybridizations were performed with antisense (C and E) or sense (D and F) GRXS17 cDNA probes.
