Despite numerous studies aimed at unraveling the genetic background of barley's response to abiotic stress, modulation transcriptome induced by combinatorial drought and increased temperature remains largely unrecognized. Very limited were done, especially on flag leaf, which plays an important role in grain filling cereals. In present study, profiles, along with chlorophyll fluorescence parameters yield components, compared between barley genotypes different leaf sizes under single combined heat stress. High-throughput mRNA sequencing revealed 2,457 differentially expressed genes, functionally interpreted using Gene Ontology term enrichment analysis. The transcriptomic signature double stress was more similar effects caused than elevated temperature; it also manifested phenotypic levels. Both common stress-specific changes transcript abundance identified. Genes regulated commonly across treatments, determining universal responses, associated, among others, responses drought, heat, oxidative addition, specific size blade found. Our study allowed us identify sets genes assigned various processes underlying including photosynthesis, abscisic acid pathway, lipid transport. encoding LEA proteins, dehydrins shock treatments. Some association composition confirmed. However, there no general coincidence SNP polymorphism differential expression factors. This research provided novel insight into molecular mechanisms that determine response, as well their co-occurrence.

Response of plant life forms and soil physical properties to near-natural restoration measures in alpine grassland, Tibetan plateau

Frontiers in Plant Science, Journal Year: 2025, Volume and Issue: 15

Introduction Near-natural restoration measures enhance the stability of plant life forms in degraded grasslands, facilitating natural succession communities. Methods In this study, we investigated effects three on alpine meadows northeastern Tibetan Plateau: banned grazing (BG), rest (RG), traditional (TG), and continuous (CG). We utilized redundancy analysis (RDA), variation partitioning(VP), hierarchical partitioning (HP), partial least squares pathway modeling (PLS-PM) to dissect quantitative relationships between distribution soil physical properties under these measures. Results discussion The results indicated following: 1) Under each measure, form plants were predominantly characterized by highest number hemicryptophytes, followed geophytes, with therophytes. found that BG treatment had hemicryptophyte height, coverage, aboveground biomass, importance value, while CG lowest. 2) After near-natural restoration, bulk density (BD) was decreased. moisture characteristics (MC) increased including saturated water content(SSWC), capillary holding capacity (CWHC), field (FWC). And porosity (CP) non-capillary (NP) increased. 3) VP revealed MC, BD, CP together explained 57.4% 4) hemicryptophytes benefited from CP. contrast, decrease BD negatively affected geophytes. summary, reduce enhancing MC increasing CP, which affects forms. This finding reveals important role survival strategies during meadow restoration.
