查询词典 simultaneous differential equations

The results showed that about610 protein spots could be visualized on the two dimensional electrophoresis map bycoomassie brilliant blue staining within Mr 9.0～100.0kD and pH 4～7,and about 94 spotswere differential expressed between male-sterile line and its maintainer line by PDQuestsoftware.Among those differential proteins,about 49 spots and 40 spots were differentialexpressed between uninucleate anther stage and binucleate stage respectively;Meanwhilecomparing with the 2-DE maps of the total proteins from the binucleate anther stage anduninucleate stage,15 differential spots were detectable at male-sterile line;and 16 differentialspots were detectable at its maintainer line.
