外源 NO 对低温胁迫下小麦幼苗果聚糖合成及 FBEs 表达的影响
Effects of Exogenous Nitric Oxide on Fructan Anabolism and FBEs Expression in Wheat under Chilling Stress
摘要
Abstract
The effects of exogenous NO on wheat (Triticum aestivum L.) growth,solubility sugar,fructan bio-synthesis metabolism etc.under 4 ℃chilling stress were investigated in seedlings ,subjected to different concentra-tions of sodium nitroprussiate(SNP,as nitric oxide donor) for 0,24,48,96 h.The results showed that,under chilling stress,exogenous NO could induce wheat weight ,fructose,glucose,low DP fructan,total soluble sugar content and fructan:fructan 1-fructosyltransferase(FFT) activity.Moreover,NO could regulate the gene expression at this level in following ways:sucrose:sucrose 1-fructosyltransferase (1-SST) and sucrose:fructan 6-fructosyltransferase (6-SFT) gene expression were inhibited by high concentration of SNP while 1-FFT was induced.Our report owing that exogenous NO alleviated the negative effects of non-freezing low temperatures by regulating FEBs and accumulating fructans.关键词
