Homoeologous exchange-associated ABA catabolism rewiring contributes to salinity tolerance in a synthetic tetraploid rice

Whole-genome duplication reshapes gene-miRNA regulatory networks underlying improved salt stress tolerance in Medicago sativa.

CHH demethylation of the BcMAM1 promoter contributes to cold tolerance in autotetraploid wucai (Brassica campestris L.).

Polyploidization has long been recognized as a driving force in plant adaptation to adverse environments. Chilling injury poses a major challenge to global crop production, and the regulatory hierarchies that govern cold adaptation in polyploid crops are unexplored. Here, we show that tetraploid wucai (Brassica campest...

The R2R3-MYB transcription factor ScMYB20 negatively regulates drought and salt tolerance through a dual-repression of ScCHALCONE SYNTHASE-1 (ScCHS1)-mediated flavonoid biosynthesis in the desert moss Syntrichia caninervis.

A dual-repression module is defined (ScMYB20-ScTTG1-ScCHS1) that fine-tunes flavonoid flux under abiotic stress, and provide evolutionary and mechanistic insights into how R2R3-MYB repressors evolved to balance metabolic investment and stress survival in land plants.

Genome-Wide Characterization of the Wheat Pum Gene Family and Heterologous Functional Analysis of TaPum-III-5b in Arabidopsis Under Salt Stress

Results support a proposed regulatory framework in which TaPum-III-5b may contribute to salt-stress responses through as-yet-unidentified downstream RNA targets through as-yet-unidentified downstream RNA targets.

Genomic and Transcriptomic Analysis of Nine Resurrection Plant Species: Conserved Regulation Versus Structural Paralog Capacity in Desiccation Tolerance

Background/Objectives: Vegetative desiccation tolerance (VDT) has arisen independently in numerous angiosperm lineages, yet it remains unclear which of its molecular features are genuinely conserved beyond individual lineages. Methods: We compiled and compared available genome assemblies and de novo transcriptomes for...

Transcriptomics and resequencing reveal dual evolutionary strategies for salt tolerance in foxtail millet (Setaria italica (L.))

A dual-layered mechanism for foxtail millet salt tolerance is suggested, likely coordinated by localized adaptive selection at core genomic nodes and dynamic plasticity within transcriptional networks and dynamic plasticity within transcriptional networks.
