In different tissues and at different fruit development stages, the FtMADS genes obtained by real-time quantitative PCR (RT-qPCR) showed obvious expression patterns. The results showed that the FtMADS genes belonged to related sister pairs and the chromosomal map showed that the replication of FtMADSs was related to the replication of chromosome blocks. According to the phylogenetic relationship of MADS genes, the transcription factor family was divided into two subfamilies, the M subfamily (28 genes) and the MIKC subfamily (37 genes).
Here, we provide a complete overview of the gene structure, gene expression, genomic mapping, protein motif organization, and phylogenetic relationships of each member of the gene family. In this study, 65 MADS genes of tartary buckwheat were identified and renamed according to the chromosomal distribution of the FtMADS genes.
The recently published whole genome sequence of tartary buckwheat allows us to study the tissue and expression profiles of the MADS gene in tartary buckwheat at a genome-wide level. However, there has been little research on the MADS genes of tartary buckwheat ( Fagopyrum tataricum), which is an important edible and medicinal crop. The MADS gene in plants controls all aspects of tissue and organ growth and reproduction and can be used to regulate plant seed cracking. The MADS transcription factor is a key regulatory factor in the development of most plants. Genome-wide identification, expression analysis and potential functional characterization of previously uncharacterized MADS family of tartary buckwheat, emphasized the importance of this gene family in plant growth and development.
