title: [Proteome analysis of potato drought resistance variety in Ninglang 182 leaves under drough stress].
abstract: It is utmost important to cultivate potato variety with drought resistance to reduce arid loss by research progress on potato drought resistance molecular mechanism. A comparative study with differences in protein group analysis of potato drought resistance variety in Ninglang 182 leaves was carried out by using two-dimensional gel electrophoresis during drought and normal processing conditions.There were 12 differentially expressed protein spots identified by Electro-phoresis and MALDI-TOF-TOF/MS analysis. The function classification of these proteins results that the potato varieties to drought tolerance could be improved through the protection of photosynthesis and mitochondria, regulation of the signal transduction induced under environmental stress and regulation of plant tissue N and C transport system, these proteins expression were increased under drought.The results showed that these proteins are the drought resistance associated proteins of potato variety in Ninglang 182.This study provided a theoretical basis of the molecular mechanism of improving drought tolerance in order to expound the potato drought resistance variety through multiple paths and the level regulation.
