TL;DR
Key transcriptomic mechanisms underlying Trichoderma responses to single and combined abiotic stresses are elucidated and provide a theoretical foundation for the targeted improvement of stress-tolerant strains to enhance their agricultural and industrial utility.
New insights are provided into the coordinated regulatory network of cool-season turfgrass in response to multiple abiotic stresses and it offers potential targets for genetic improvement and functional utilization of stress-tolerance genes.

Combined stress more strongly inhibited plant height, stem diameter, fresh weight, net photosynthetic rate, and transpiration rate than single stresses, and insights into alfalfa adaptation to multiple abiotic stresses are provided.

Drought stress driven by global climate change critically restricts mulberry growth. The identification of drought-responsive genes in the Yunnan-adapted Yunsang cultivar is essential for mitigating environmental constraints on sericulture. In this study, seedlings of the mulberry cultivar Yunsang-2 were subjected to drought stress under greenhouse conditions. Leaf samples were collected for physiological analysis (proline content and CAT and POD activities) and transcriptome profiling via RNA-Seq. The results revealed that compared with the plants in the CK group, the drought-stressed plants had significantly increased CAT and POD activities by 7 days post-stress (DPS) and accumulated markedly greater amounts of proline at 9 and 12 DPS. Transcriptomic analysis revealed that drought resistance involves key genes enriched in the abscisic acid (ABA), gibberellin (GA), and brassinosteroid (BR) signaling pathways, such as PYR, ABF, PIF3, and BSK. Furthermore, we identified 156 TFs as potential regulatory hubs. Among these genes, MnERF21 was tentatively identified as a candidate positive regulator of drought resistance. Our findings systematically elucidate the molecular mechanisms underlying drought tolerance in mulberry and provide novel insights into the drought resistance strategies of Yunnan-adapted germplasms.

Drought inhibits grass development and survival. However, molecular-based studies on drought tolerance mechanisms in bermudagrass (Cynodon dactylon) remain scarce. Therefore, a drought-resistant bermudagrass (Tianshui) and a drought-sensitive (Zhengzhou) genotype were selected and subjected to 28 days of 50% drought stress. Leaves were sampled for RNA sequencing. Under drought stress, 2410 differentially expressed genes (DEGs) were discovered in which 1214 were upregulated (tolerant vs. sensitive) and 1196 downregulated. Kyoto Encyclopedia of Genes and Genomes (KEGG) indicated that these specific DEGs are notably present in hormonal signal transduction pathways, flavonoids biogenesis, carbohydrate metabolic processes, abscisic acid-mediated pathways, MAPK signaling, and gluconeogenesis. Additionally, the plant hormone signal transduction pathway is predominantly linked to abscisic acid signal transduction, and many other plant hormones were also drought-responsive. The study specifically targeted genes associated with the antioxidant enzyme system, with a particular emphasis on responsive TFs such as MYB, bHLH, bZIP, GRAS, and WRKY. This study establishes the theoretical framework and identifies gene sources for the genetic enhancement and breeding of bermudagrass in the future.

FaNAC6 was selected for its strong induction in leaves and roots in response to drought and salinity, as well as under oxidative stress and ABA, and was associated with the upregulation of genes involved in photosystems, electron transport and carbon fixation.
