Abstract excerpt
Wild perennial sister species Medicago archiducis-nicolai (rhizomatous/alpine) and M. ruthenica (non-rhizomatous/xeric) constitute vital genetic resources for forage improvement. To decode the genomic basis of their contrasting trait and habitat adaptation, we generated chromosome-scale genome assemblies, resequenced 128 individuals, profiled transcriptomes under cold/heat stress, and functionally validated...
