Genomic Variation Underpins Genetic Divergence and Differing Salt Resilience in Sesbania bispinosa.

ABSTRACT: Halophytes possess inherent stress resilience and diverse adaptations, making them valuable genetic reservoirs for crop breeding. The leguminous halophyte Sesbania bispinosa is a valuable forage crop that thrives in saline soils. To explore its salt tolerance, high-quality genome assemblies is generated for the salt-tolerant S. bispinosa accession SbTA02 and the salt-sensitive accession SbSA44. Genomic analysis revealed that the genomic divergence between the two accessions primarily originates from their pericentromeric and centromeric regions, which contain the two largest inversions: a >27-Mb inversion on chromosome 5 and a ≈49-Mb inversion on chromosome 6. Population-level analysis revealed that the 27-Mb inversion is widespread in S. bispinosa, dividing the tested populations into inl
