2个枇杷品种果皮日灼伤害差异蛋白质组分析

摘要

以日灼抗性不同的2个枇杷品种为材料,对短期日灼诱导处理下果皮蛋白质组的变化进行分析.结果显示,‘红猴本,果皮日灼处理下共有32个差异表达蛋白点,其中上调表达的有17个,下调表达的有15个；‘金钟,有52个差异点,上调表达的有38个,下调表达的有14个.2个品种果皮在相同日灼处理下差异表达蛋白数量明显不同,预示这2个品种对日灼的敏感性不同.%Two-dimensional gel electrophoresis was employed to analyze the proteome of loquat peel in two varieties which have different resistance to high temperature stress under short-term sunburn. The results showed that the honghouben' had 32 differentially expressed proteins point, including 17 up-regulated, 15 down-regulated, and the jinzhong' had 52 differentially expressed proteins point, including 38 up-regulated, 14 down-regulated under short-term sunburn. The quantity of differentially expressed proteins of loquat peel in two varieties was different. It implicated that two varieties had different sensitivity to sunburn.
