    There is a significant genetic diversity and distinct phylogenetic clusters in the matK gene among African yam bean and legumes.– Edu et al. 2025

    The study delves into the genetic diversity and evolutionary relationships of the matK gene in Sphenostylis stenocarpa (African yam bean) and its related legume species. The matK gene, a chloroplast marker with a high substitution rate, is widely used in studying genetic diversity and species evolution. The authors retrieved nucleotide sequences for several leguminous species, including S. stenocarpa, Sphenostylis angustifolia, Vigna aconitifolia, Vigna angularis, Vigna umbellata, Vigna mungo, Cajanus cajan, Phaseolus vulgaris, and Glycine max from the NCBI database. The authors used MEGA 6 software with Clustal W alignments and 1000 bootstrap resampling to assess phylogenetic relationships. The secondary and tertiary structures of proteins of the matK gene were predicted using the GORIV and Phyre2 tools. The phylogenetic analysis revealed two primary clusters: one containing exclusively P. vulgaris with high bootstrap support and another encompassing the remaining legumes, further divided into sub-clusters with C. cajan distinct from Vigna species. Structural analysis showed that S. stenocarpa exhibited the highest percentage of alpha helix (36.54%), while C. cajan displayed the lowest alpha helix and highest random coil.
