The study tracked molecular changes in plastoglobules and thylakoids of Zea mays B73 during heat stress and recovery, revealing increased plastoglobule size, number, and adjacent lipid droplets over time. Proteomic and lipidomic analyses uncovered up‑regulation of specific plastoglobule proteins and alterations in triacylglycerol, plastoquinone derivatives, and phytol esters, suggesting roles in membrane remodeling and oxidative defense. These insights highlight plastoglobule‑associated pathways as potential targets for enhancing heat resilience in maize.

The study compared two plasma‑activated water (PAW) solutions with different H₂O₂ levels, produced by a radio‑frequency glow discharge, on Arabidopsis thaliana growth and stress responses. PAW lacking detectable H₂O₂ promoted seedling growth and induced nitrogen‑assimilation genes, while H₂O₂‑containing PAW did not affect growth but enhanced root performance under heat stress; mature plants fertilized with H₂O₂‑free PAW performed comparably to nitrate controls. These results indicate PAW can replace NO₃⁻ fertilizers provided H₂O₂ levels are carefully managed.

The study introduced full-length SOC1 genes from maize and soybean, and a partial SOC1 gene from blueberry, into tomato plants under constitutive promoters. While VcSOC1K and ZmSOC1 accelerated flowering, all three transgenes increased fruit number per plant mainly by promoting branching, and transcriptomic profiling revealed alterations in flowering, growth, and stress‑response pathways.

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 examines how the SnRK1 catalytic subunit KIN10 integrates carbon availability with root growth regulation in Arabidopsis thaliana. Loss of KIN10 reduces glucose‑induced inhibition of root elongation and triggers widespread transcriptional reprogramming of metabolic and hormonal pathways, notably affecting auxin and jasmonate signaling under sucrose supplementation. These findings highlight KIN10 as a central hub linking energy status to developmental and environmental cues in roots.

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.
