Abstract

Data from cDNA-AFLP analysis based on the genome-wide transcriptional profiling on the flower buds of the male meiotic cytokinesis (mmc) mutant and its wild-type of Brassica campestris L. ssp. chinensis Makino, syn. B. rapa L. ssp. chinensis, indicated that mutation of the MMC gene resulted in changes in expression of a variety of genes. A transcript-derived fragment specifically accumulated in the wild-type flower buds was isolated, and the corresponding full-length cDNA and DNA was subsequently amplified. Bioinformatical analyses of this gene named BcMF15 (GenBank accession number EF600901) showed that it encoded a protein with 103 amino acids. The BcMF15 had a 88% nucleotide similarity to a lipid transfer protein-like gene. Moreover, sequence prediction indicated that BcMF15 might encode a membrane protein with a signal peptide at the N-terminus. Meanwhile, six domains were predicted in the deduced BcMF15 protein, such as the AAI domain existing in some crucial proteins of pollen development-preferential, signal peptide, transmembrane domain, vWF domain, ZnF_C4 domain, and Tryp_alpha_amyl domain. Spatial and temporal expression patterns analysis by RT-PCR indicated that BcMF15 was exclusively expressed in the fertile line, which indicated this gene is male sterile related. Phylogenetic analysis in Cruciferae revealed that the BcMF15 was relative conservative in evolution. We suppose BcMF15 may be a critical molecule in the transmembrane transportation and signal transduction during microspore development.
