The paper examines how phenotypic plasticity in Populus species affects fitness under climate warming, finding that higher plasticity is maladaptive in warmer environments.

The paper predicts geographic shifts in hybrid Populus zones based on temperature response variation in admixed genotypes.

This study examines how climate and hybridization influence stomatal trait evolution in Populus by analyzing genetic and environmental factors across hybrid zones.

The paper examines cytonuclear interactions in Populus hybrids, finding that chloroplast and nuclear-chloroplast gene co-introgression is limited but influenced by local environments, affecting physiological performance.

This study observes rapid genetic adaptation and population dynamics in Arabidopsis thaliana across diverse climates over 5 years, showing predictable adaptation trends linked to survival and extinction risks.

This study identifies the hybrid origin of Populus tomentosa through genome sequencing and phylogenomic analysis, revealing it resulted from hybridization between Populus adenopoda and Populus alba var. pyramidalis around 3.93 Mya.
