The genome of Eleocharis vivipara elucidates the genetics of C₃-C₄ photosynthetic plasticity and karyotype evolution in the Cyperaceae.

ABSTRACT: Eleocharis vivipara, an amphibious sedge in the Cyperaceae family, has several remarkable properties, most notably its alternate use of C₃ photosynthesis underwater and C₄ photosynthesis on land. However, the absence of genomic data has hindered its utility for evolutionary and genetic research. Here, we present a high-quality genome for E. vivipara, representing the first chromosome-level genome for the Eleocharis genus, with an approximate size of 965.22 Mb mainly distributed across 10 chromosomes. Its Hi-C pattern, chromosome clustering results, and one-to-one genome synteny across two subgroups indicates a tetraploid structure with chromosome count 2n = 4x = 20. Phylogenetic analysis suggests that E. vivipara diverged from Cyperus esculentus approximately 32.96 mi
