Abstrakt

Understanding how plants navigate environmental adversity requires peering into the molecular choreography of stress adaptation, a view now achievable through mass spectrometry-based omics. By integrating proteomics, lipidomics, and metabolomics as complementary molecular lenses, we unveiled the hidden architecture of cold acclimation and drought resilience in Arabidopsis thaliana. Thousands of responsive proteins emerged from the data, revealing development-dependent survival strategies in which tissue age plays a decisive role in shaping stress mitigation and resilience. Young and aging leaves express distinct molecular dialects under stress, suggesting an intergenerational compromise within the plant body. In total, 2,064 early-response proteins were identified during cold treatment, reflecting extensive proteome reprogramming that underpins acclimation. Under drought conditions, genotypes with contrasting resilience revealed age-dependent molecular mechanisms that bolster plant survival, identifying several hundred candidate targets for enhancing drought tolerance. This omics-driven narrative reframes plant stress biology—from static gene inventories to dynamic molecular ecosystems—charting pathways toward crops engineered not merely to survive, but to thrive under environmental duress.
