According to the analysis and identification of differential displayed proteome , two key enzymes , adp - l - glycerol - d - mannoheptose - 6 - epimerase and mannosyltransferase , were induced in different salt stress and salt shock for rt19 , which commonly participate in the biosynthesis of l - glycerol - d - manno - heptose , a major component of lipopolysaccharide 通过对rt19的盐激和盐胁迫诱导蛋白的比较分析，发现：其中12个蛋白在两种不同的胁迫条件下都可被诱导表达。进一步证实： rt19应答不同盐胁迫刺激采取了不同的反应机制，但这些机制存在共性，交织成复杂的调控网络。
