Genome-Wide Analysis of the Rab Gene Family in Melilotus albus Reveals Their Role in Salt Tolerance

ABSTRACT: Melilotus albus is a high-quality forage, due to its high protein content, and aboveground biomass and salt tolerance. Rab (Ras-related protein in the brain) proteins are the largest GTPase family which play a key role in intracellular membrane transport, and many Rab genes have been identified in eukaryotes. The growth and distribution of M. albus are severely hampered by soil salinization. However, little is known about candidate genes for salt tolerance in M. albus. In this study, 27 Rab family genes were identified for the first time from M. albus, and divided into eight groups (Groups A-H). The number of introns in MaRabs ranged from one to seven, with most genes containing one intron. In addition, most MaRab proteins showed similarities in motif composition. Phylogenetic analysis and
