The study used transcriptomic and lipidomic profiling to investigate how chia (Salvia hispanica) leaves respond to short‑term (3 h) and prolonged (27 h) heat stress at 38 °C, revealing rapid activation of calcium‑signaling and heat‑shock pathways and reversible changes in triacylglycerol levels. Nearly all heat‑responsive genes returned to baseline expression after 24 h recovery, highlighting robust thermotolerance mechanisms that could inform improvement of other oilseed crops.

Prosopis cineraria plants were exposed to two heat stress regimes (45 °C and 55 °C) and subjected to transcriptome sequencing, revealing 1,151 and 1,562 differentially expressed genes respectively, with the higher temperature eliciting a stronger response. Bioinformatic analysis highlighted multiple gene families associated with thermotolerance, and the expression of selected heat‑responsive genes was confirmed by real‑time qPCR, providing candidate loci for crop improvement.

The study demonstrates that N6‑methyladenosine (m6A) RNA methylation acts as a negative regulator of thermotolerance in Arabidopsis thaliana, with loss of m6A increasing heat‑responsive gene expression and mRNA stability. Heat shock triggers a transient reduction of m6A levels, which is linked to enrichment of the H3K4me3 histone mark at target loci, enhancing transcription of heat shock proteins. These findings reveal a coordinated interplay between RNA methylation and chromatin modifications that fine‑tunes the plant heat stress response.

The study examined how Arabidopsis thaliana integrates physiological, genetic, hormonal, and transcriptomic responses to combined water deficit, heat stress, and elevated CO2. Results show that stomatal aperture under these complex stress combinations is governed by a specific set of regulators, including nitric oxide, OPEN STOMATA 1, and the SLAH3 anion channel, distinct from those active under simpler stress conditions. This reveals a hierarchical stomatal stress code that could inform future research on plant resilience to global change.

A two‑year field study examined how soybean (Glycine max) vegetative and reproductive tissues respond transcriptionally and physiologically to water deficit, heat, and their combination. The field‑grown plants showed distinct transcriptomic patterns compared with controlled‑environment studies, especially under single stresses, while differential leaf‑pod transpiration observed in growth chambers was also present in the field. The generated transcriptomic dataset highlights the importance of field‑based omics for understanding crop stress responses.

The study evaluated how acute heat stress affects early-stage rice seedlings, identifying a critical temperature threshold that impairs growth. Transcriptomic profiling of shoots and roots revealed ethylene‑responsive factors (ERFs) as central regulators, with ethylene and jasmonic acid acting upstream, and pre‑treatment with these hormones mitigated heat damage. These findings highlight ERF‑hormone interaction networks as targets for improving rice heat resilience.

The study shows that heatwaves impair the ability of apple (Malus domestica) to mount ASM‑induced immunity against fire blight and apple scab, leading to a loss of protective gene expression. Transcriptomic analysis revealed a broad suppression of ASM‑regulated defense and other biological processes under high temperature, identifying thermo‑sensitive resistance and susceptibility marker genes. The findings highlight that elevated temperature both weakens plant defenses and creates a more favorable environment for pathogens.

The study investigated how Arabidopsis thaliana SR protein kinases (AtSRPKs) regulate alternative RNA splicing by using chemical inhibitors of SRPK activity. Inhibition with SPHINX31 and SRPIN340 caused reduced root growth and loss of root hairs, accompanied by widespread changes in splicing and phosphorylation of genes linked to root development and other cellular processes. Multi‑omics analysis (transcriptomics and phosphoproteomics) revealed that AtSRPKs modulate diverse splicing factors and affect the splicing landscape of numerous pathways.

The study examined how heat stress alters lipid droplet (LD) number and composition in Arabidopsis thaliana roots, revealing degradation of membrane lipids and accumulation of TAGs and LDs. Proteomic and lipidomic analyses of LDs from a specific Arabidopsis mutant identified novel LD-associated proteins, including triterpene biosynthetic enzymes, whose substrates and products also accumulate in LDs, indicating LDs function as both sinks and sources during stress‑induced membrane remodeling and specialized metabolism.

The study investigates the role of the Arabidopsis transcription factor AtMYB93 in sulfur (S) signaling and root development, revealing that AtMYB93 mutants exhibit altered expression of S transport and metabolism genes and increased shoot S levels, while tomato plants overexpressing SlMYB93 show reduced shoot S. Transcriptomic profiling, elemental analysis, and promoter activity assays indicate that AtMYB93 contributes to root responses to S deprivation, though functional redundancy masks clear phenotypic effects on lateral and adventitious root formation.
