Summary: Cotton breeding programs need to select for tolerance to high temperature extremes to prevent environment-induced yield loss. Methods that combine chlorophyll fluorescence induction measurements with temperature response experiments can be used to identify genotypic variation in photosynthetic thermotolerance. Cotton genotypes differ significantly in photosynthetic thermotolerance, and different photosynthetic processes have varying sensitivities to high temperature, with intersystem electron transport being the most heat sensitive.

Summary: The study found that under optimal temperature, the im mutant displayed similar photosynthetic performance as TM-1, but under high temperature stress, the im mutant reduced photosynthesis by disproportionately decreasing stomatal conductance. Transcriptomic analysis showed differences in expression of heat stress response genes between NIL leaves, suggesting that mitochondrial complex I activity is required for optimal photosynthetic performance and adaptation to high temperature stress.

Summary: An evolutionary model using diploid and allotetraploid cotton species found that 80% of non-coding transcripts in allotetraploid cotton are uniquely activated compared to its diploid ancestors. The function of activated lncRNAs in allotetraploid cotton is largely unknown. Transcriptome analysis revealed that lncRNA expression is preferentially associated with flanking PCGs, and a low-throughput functional screening identified lncRNAs related to plant height and stress tolerance. The study suggests that lncRNAs are more active under abiotic stresses, such as temperature stress, and may play a cis-regulatory role in response to environmental stimuli.

Summary: High light intensity has a significant impact on the photosynthetic apparatus of tomatoes. Different genotypes show varying responses, with tolerant genotypes exhibiting reduced photoinhibitory quenching compared to sensitive genotypes. Quantum yield components also shift under high light, favoring the quantum yield of non-photochemical quenching and basal energy loss, while reducing the quantum yield of photosystem II. These findings provide insights into the mechanisms of high light tolerance in tomatoes and can aid in the development of resilient crops for variable light conditions.

Summary: Regulation of stomatal speed can be achieved by manipulating the expression of guard cell sucrose synthase 2 (NtSUS2), leading to slower light-induced stomatal opening, lower steady-state stomatal conductance, and reduced whole plant transpiration. Additionally, plants with reduced NtSUS2 expression show higher water use efficiency under short water deficit periods. This suggests a complex modulation of the guard cell metabolic network in regulating stomatal movement and speediness.

Summary: This study identified the roles of two mitochondrial phosphatases, Sal2 and PP2c63, along with pyruvate dehydrogenase kinase (PDK), in regulating the tricarboxylic acid (TCA) cycle. PDK specifically regulates the pyruvate dehydrogenase complex (PDC), while PP2c63 nonspecifically regulates PDC. The study also showed that these phosphatases affect flux through the TCA cycle and altered metabolism compromises plant growth in mutant lines.

Summary: Recent research suggests that metabolism-mediated stomatal closure mechanisms play a crucial role in regulating the differences in stomatal speediness between ferns and angiosperms. Ferns showed a lack of response to ABA and slower stomatal responses to sucrose and mannitol compared to angiosperms. Metabolomics analysis revealed that ferns accumulate more secondary metabolites than primary metabolites throughout the diel course, presenting a potential mechanism for the slower stomatal closure and differences in response to exogenous substances between ferns and angiosperms.

Summary: This study evaluated the seminal plasma metabolome of Bos indicus Guzera bulls with good and poor sperm freezability. Sixty-two metabolites were identified in the seminal plasma, with fatty acids and conjugates and organic compounds being the predominant metabolites. Multivariate analysis showed a distinct separation of seminal plasma metabolomes between bulls with contrasting sperm freezability. Specific metabolites, such as propanoic acid, d-ribose, and glycine, were found to be associated with good sperm freezability, while heptadecanoic acid and undecanoic acid were predominant in bulls with poor sperm freezability. This study provides important information about the seminal plasma metabolome of tropically adapted bulls and its association with sperm freezability.

Summary: This study demonstrated that co-expressing two exogenous genes, tfdB and bphC, in Arabidopsis thaliana improved the tolerance and removal efficiency of PCB28. Transgenic plants also exhibited increased enzymatic activities under PCB28 stress. The co-expression of tfdB and bphC in A. thaliana resulted in nearly twofold increase in PCB28 removal rates from soil. This research suggests that co-expressing two genes holds great potential for enhancing phytoremediation efficiency and mitigating PCB-induced toxicity stress on plants.

Summary: In eukaryotic cells, epigenetic modifications of DNA and histones play a crucial role in gene expression regulation. ROXY19, a plant-specific CC-type glutaredoxin, was found to strongly repress a subset of genes regulated by class II TGA factors through its association with the TPL/TPR family. The ectopic expression of ROXY19 in Arabidopsis plants led to hypersensitivity to xenobiotic chemicals due to the silencing of detoxification pathway genes.

Summary: Soil salinization is a major obstacle for agriculture sustainability, as it severely affects plant growth and crop yield. Ethylene, a stress hormone, plays a crucial role as a signal molecule in coordinating plant growth and stress response in the model plant Arabidopsis. However, the roles and mechanisms of ethylene in most crop plants under salinity remain undefined. This review summarizes the universal roles of ethylene and focuses on its divergent roles in rice and other crop species under salinity, particularly in terms of ethylene biosynthesis and signal transduction. The contradictions between ethylene production and signaling in salt response are also discussed.
