Abstract:Proteomatic analysis is a new powerful tool for revealing the changes in protein level. Two-dimensional polyacrylamide gel electrophoresis （2DE） and computer image analyses were employed to compare the global protein patterns between normal and aborted embryo of litchi （Litchi chinensis Sonn.）. Totally, 129 and 130 protein spots were obtained from normal and aborted embryos, respectively, of which 24 spots in both kind of embryos showed no significant difference, but 35 spots exhibited obvious differences in quantity, Furthermore, some spots were missing and some new spots emerged in aborted embryo compared with normal embryo. The differences in expressing the proteins between normal and aborted embryos of litchi are useful for regulating and controlling the embryo abortion.
