Effect of NO on hypocotyl elongation and DELLA content under red light. A and C, Hypocotyl length of wild-type Ler, rga-24gai-t6, and quadruple (4della) and quintuple (5della) DELLA mutants was measured after growing seedlings in the indicated SNP concentrations for 3 d. Values of hypocotyl length are means ± se of three independent experiments (at least 20 seedlings per experiment were measured). Asterisks represent statistically significant differential values with at least P < 0.05 when comparing hypocotyls of treated versus untreated wild-type seedlings (A) or mutant versus wild-type hypocotyls from different genotypes under the same treatment conditions (C). B, TAP-DELLA accumulation under the SNP concentrations shown in A was detected with anti-MYC antibodies, and the loading controls of tubulin (TUB) are included.
