摘要/Abstract

摘要：

缺钙花生（Arachis hypogaea L.）严重空荚（胚胎败育）导致减产降质长期困扰南方花生生产。以大田足（施足钙）、缺（缺钙地大田本底）钙条件下花生的种植与观察为基础，利用改良的传统双向电泳、MALDI-TOF质谱和蛋白质数据库等手段，得到了7个与受钙影响花生早期胚胎败育/发育有关的差异表达蛋白。4^#差异蛋白是与菠菜（Spinacia oleracea）的70 kD的叶绿体被膜休克相关蛋白高度相似的缺钙组表达上调的特异蛋白; 6^#差异蛋白与三叶胶（Hevea brasiliensis）的线粒体前体中的ATP合酶的β链高度相似,该蛋白在缺钙幼胚缺失; 7^#差异蛋白在低钙组缺失,其与马铃薯（Solanum tuberosum）的肌动蛋白97或100类似,等等。研究结果提示，受钙胁迫花生幼胚败育可能与早期幼胚内能量转化、氧化还原系统、细胞内膜以及细胞骨架功能维持相关的功能基因的表达异常有关。初步揭示了受钙影响花生胚胎败育的分子机理。

Abstract:

Empty pods and ill-filled pods leading to low yield in peanut production resulted from deficient calcium has long been an existing problem in the red and yellow soil regions in the south China. Based on the measurements and comparisons in field experiments with different levels of calcium, the seven differentially expressed proteins which related to the development /abortion embryos of peanut were got by 2-D electrophoresis, MALDI-TOF-MS and protein databases. The results searched from the protein databases were as follows: 4^# protein, which up-regulated in embryos from deficient calcium group, showed high homology with the 70 kD protein from the chloroplast envelope membrane of Spinacia oleracea L; 6^# protein disappeared in embryos from deficient calcium group showed high homology with the β-chain of the (ATPB) ATP synthase from Hevea brasiliensis L; and 7^# protein also disappeared in embryos from deficient calcium group was considered similar to the Actin 97&100 from Solanum tuberosum,etc. All the results indicated that the molecular mechanism of embryo abortion mediated by calcium may be relevant to some genes controlling energy transferring（ATP synthesis）, oxidoreduction system, endo-membrane system and cytoskeleton structure system which are transcripted or expressed unnomally.
