Firstly,a differential TDF(Transcript Derived Fragments)EST54-1 from the RNA of bud aborting of male sterile Chinese cabbage by cDNA-AFLP analysis was used as a querying probe to blast homologous ESTs sequences in the GenBank database,we spliced the homologous EST sequences assembled from GenBank,and gained an virtual sequence of 1 574 bp length.

For studies of differential gene expression, cDNA-AFLP was analyzed in tea plant at the stage of bud flower development.

Aborted bud of Chinese cabbage and radish is a disadvantageous phenomenon in breeding practise.

Comparison of male gametophyte development and pollen sterility of Jingbaili and Yali pear cultivars;

The pollen sterility had nothing to do with tepetum in pollen sac wall.

Investigation and Analysis on the reasons of the low fruit set rate of wild watermelon introduced and cultivated from the Jianghan Plain,the results showed that the main reasons of low fruit set rate are the excessive growth of the plant,the high rate of Pollen sterility,the less amount of female flower,the high death rate of female bud and the fruit aborting etc.

Cytological studies on pollen abortion of male sterile lines with Aegilops bicornis cytoplasm in wheat;

Studies on the Relation between Pollen Abortion and Apoptosis of Young Spike and Anther in Rice;

The results showed that no self-incompatibility appeared in artificial self pollination of Torenia fournieri plants,but pollen abortion had occurred in its transgenic plants.
