Proteomic analysis of heterosis during maize seed germination

摘要：

　　Heterosis is observed for most phenotypic traits and developmental stages in many plants.In this study,the embryos,from germinating seeds after 24 h of soaking,for five elite maize hybrids and their parents were selected to unravel the genetic basis of heterosis using 2 - D proteomic method.In total,257 (80.06%),363 (58.74%),351 (79.95%),242 (54.50%),and 244 (46.30%) nonadditively expressed proteins were identified in hybrids Zhengdan 958,Nongda 108,Yuyu 22,Xundan 20,and Xundan 18,respectively.
