Climate change is intensifying the co‐occurrence of salinity and waterlogging, exposing plants to a compound stress that is difficult to predict from single‐stressor responses. Here, we synthesized evidence from 109 studies encompassing 4597 observations to quantify how plant growth and key physiological modules respond to salinity, waterlogging, and their combination across major ecological groups and crops. Across moderate s...

Understanding the genetic, and transcriptomic changes that drive the phenotypic plasticity of fitness traits is a central question in evolutionary biology. In this study, we utilised 152 natural Swedish Arabidopsis thaliana accessions with re‐sequenced genomes, transcriptomes and methylomes and measured flowering times (FTs) under two temperature conditions (10°C and 16°C) to address this question. We revealed that the norther...
