【摘要】 干旱胁迫可能改变蛋白质的数量和质量。通过对喜钙植物——云贵鹅耳枥在干旱胁迫下总的可溶性蛋白质含量的变化和Ca2+对可溶性蛋白质数量和质量影响的调查分析。结果显示:在20%PEG-6000溶液胁迫下,叶片中总的可溶性蛋白质含量变化不显著,而在30%PEG-6000溶液胁迫下,叶片中总的可溶性蛋白质含量下降。同时,总的可溶性蛋白质含量的下降受到Ca2+的抑制。更多还原

【Abstract】 Drought stress may alter protein quantities and qualities.The objectives of this study were to investigate total protein content changes in response to drought stress and effect of Ca2+ on soluble protein quantities and qualities in the Carpinus pubescens,a calcicole.The results showed that total protein content from leaves had not a remarkable change under drought stress with 20% PEG-6000 solution and decreased with 30% PEG6000 solution.The decrease of total protein content was inhibited in the treated condition,in which Ca2+ was used under drought stress with 30% PEG-6000 solution.更多还原
