两个膨胀素基因在矮化黄瓜D0462组织中的表达

摘要

为研究膨胀素基因表达与矮化之间的关系，以膨胀素基因Cs-EXPA1和Cs-EXPA2为研究对象，通过分析2个膨胀素基因之间的联系与相互作用发现，2个基因的表达都具有组织特异性，其中Cs-EXPA1与下胚轴伸长的关系更紧密，而Cs-EXPA2的表达很像对Cs-EXPA1的补充。%In order to explore the relationship between expansin gene expression and dwarf,taking two expansin genes Cs-EXPA1 and Cs-EXPA2 as the research objects,after analyzing the correlation and interaction of the two expansin genes,the authors found that both of the two genes had tissue specificity, of which Cs-EXPA1 was more close to hypocotyledonary axis extension,and the expression of Cs-EXPA2 was the supplement to Cs-EXPA1 .
