Allelic tuning of PtoRLK609 kinase activity shapes adaptive xylem remodeling in Populus tomentosa
Abstract Climate change poses unprecedented challenges to perennial trees. However, the molecular mechanisms by which trees achieve long-term adaptive xylem remodeling remain poorly understood. Here, using transcriptomics and population genomics in 302 Populus tomentosa accessions sampled from three climatically distinct subpopulations, we identified receptor-like kinases (RLKs) associated with…
