Fig. 2From: Molecular structures and functional exploration of NDA family genes respond tolerant to alkaline stress in Gossypium hirsutum L.Phylogenetic trees of NDA genes in four Gossypium species and other eight species using MEGA 7 by the Neighbor-Joining (NJ) method. A Phylogenetic relationship of the 153 identified NDA genes from four Gossypium species, B Phylogenetic relationship of the 247 identified NDA genes from four Gossypium species and other eight species. The 8 major phylogenetic subgroups, designated as a to g, are marked with different colored backgroundsBack to article page
