Schematic representations of the chromosomal distribution of the 26 TCPs in Tartary buckwheat. The position of the gene on the chromosome and the corresponding base pair position are marked on the left and right sides. The chromosome number and chromosome full-length base pair are labeled above and below each chromosome. The upward red arrow indicates that the gene has a reverse chain on the chromosome, and the downward red arrow indicates that the gene has a forward chain on the chromosome
