Fig. 6From: Salicylic Acid Acts Upstream of Auxin and Nitric Oxide (NO) in Cell Wall Phosphorus Remobilization in Phosphorus Deficient RiceSA enhances the NO production in response to P deficiency in rice. Root endogenous NO staining (A) indicated by green fluorescence and NO production (B) described as relative fluorescence intensity (% of minimal production) under respective conditions were displayed. Root and shoot SA content (C) in P-limited condition with or without SNP supply were measured. Data are means ± SD (n = 4 for SA content measurement, n = 8 for root NO detection). Different letters represent significant differences by Duncan’s multiple range test at the P < 0.05. Scale bar = 1 mmBack to article page
