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.

The array consisted of 8 piezoelectric crystal sensors, each coated with an adsorptive material with unselective, but different response characteristics. The frequency shift data obtained from the array as the response to mixed vapour of common organic solvents of small molecular size were treated by using stepwise discrimination analysis, and five coatings that provided the maximum level of analyte discriminating ability were selected. The array constructed from these solvents was applied to recognizing alcoholic hydroxyl, carbonyl from other organic functional groups. The principal component analysis was applied to the original and autoscalled data. The two-dimensional display of the data showed well-defined clusters for solvents containing different functional groups separated from each other. The array was applied to identifying spirits and beverages.
