Genomic and Cis ‐Regulatory Basis of a Plastic C 3 ‐C 4 Photosynthesis in Eleocharis Baldwinii (Adv. Sci. 32/2025)

Le résumé fourni par la source

C4-C3 Photosynthetic Plasticity in Eleocharis baldwinii The cover art depicts anatomical adaptations of Eleocharis baldwinii, an amphibious sedge exhibiting rare C4-C3 photosynthetic plasticity. The upper section shows submerged C3-like culms with reduced vascularization, contrasting with the lower section's terrestrial C4-like forms featuring distinct Kranz anatomy. A central transition motif illustrates culm morphism from submerged (right) to terrestrial (left) forms. This spotlight on this lesser-known species accompanies work by Xin Liu, Yongjun Lin, Xiang Li, and co-workers (article number 2415681), revealing genomic basis and cis-regulatory rewiring driving photosynthetic plasticity between environments by employing an integrated genomics and single-cell multi-omics approach on its C3-like and C4-like culms. The results highlight a genomic divergence of convergent C4 traits in monocots.
