DNA methylation plays an important role in gene expression regulation during biological development in plants. To explore the mechanism of chemically induced male sterility (CIMS) in wheat, using cDNA-amplified fragment length polymorphism (cDNA-AFLP) and methylation-sensitive amplification polymorphism (MSAP) approaches, 6.66 and 3.42 % of the sequences showed changes in gene expression and DNA methylation in 1376-CIMS as compared to its fertility line 1376. We sequenced 54 fragments that differed in cDNA-AFLP and 26 DNA fragments which differentially displayed in MSAP comparisons of CIMS and 1376. Our results provided evidences for genome-wide changes in gene expression and DNA methylation occurring in the development of the 1376-CIMS system induced by chemical hybridizing agent SQ-1, and its counterpart fertility line 1376. Moreover, this study contributed to the elucidation of CIMS effects on responses of transcriptome and methylome in the development of the anther.
