Summary: The study revealed specific recruitment of proteins related to leaf senescence and jasmonic acid biosynthesis in plastoglobules under light stress, and an increase in carotenoid abundance consistent with enhanced thylakoid disassembly. The results suggest that plastoglobule-localized ABC1 kinases hold endogenous kinase activity, facilitating stress adaptation within chloroplasts.

Summary: One of the main impacts of drought stress on plants is the excessive accumulation of reactive oxygen species (ROS), which can be highly toxic to cells if not cleared quickly. Superoxide dismutase (SOD) is a crucial antioxidant enzyme that plays the first role in scavenging active oxygen. The miR398s family of miRNAs has been shown to be significant in plants' response to environmental stress. Potato stu-miR398b-3p was found to cleave Cu/Zn SOD mRNA, and overexpression of stu-miR398b-3p led to decreased SOD activity during drought stress.

Summary: The study found that the tensile strength enhancement of high Zn-containing Al-Zn-Mg-Cu alloys was mainly due to the high density nano-scale matrix precipitates. The SCC plateau velocity was significantly higher in the alloy with 11.0 wt.% Zn compared to the alloy with 7.9 wt.% Zn, which was attributed to Zn enrichment in grain boundary precipitates and wide precipitates-free zones.

Summary: This study found that infection with the causative bacteria of edwardsiellosis, Edwardsiella tarda NUF251, leads to the production of superoxide radicals, causing oxidative stress. The research on the Jfsod1 gene suggests that the transcription factor NF-IL6 plays a significant role in upregulating the transcriptional activity of the gene in response to oxidative stress induced by NUF251 infection.

Summary: Fine-tuned interactions between melatonin (MT) and hormones affected by environmental inputs are crucial for plant growth. Under high light (HL) conditions, melatonin reduced photodamage in Arabidopsis thaliana and contributed to the restoration of cytokinin (CK) synthesis and signal transduction genes that were downregulated by stress. Conversely, cytokinin treatment increased the expression of the key melatonin synthesis gene. The results suggest that melatonin acts synergistically with CK to cope with HL stress through melatonin-associated activation or repression of the respective hormonal genes.

Summary: Research indicates that IOS1 plays an important and positive regulatory role in salt stress response in Arabidopsis. Loss-of-function ios1 mutants display increased sensitivity to salinity, higher accumulation of H2O2 under salt stress, altered expression of stress marker genes, and weakened phosphorylation of MPK6 compared to wild-type plants.

Summary: Environmental stressors such as high temperature and intense light have a negative impact on ginger growth and productivity. Ginger plants activate multiple stress response pathways and adjust their responses over time. The expression levels of genes involved in stress response pathways are differently regulated under stress conditions. These findings are important for understanding the stress mechanisms of ginger and breeding ginger genotypes that can withstand high temperatures and intense light stress.

Summary: Plants respond to the combination of salt stress and high light through metabolic changes and hormone regulation. ABA plays a crucial role in promoting plant tolerance to this combination, while JA and SA have a marginal role. Moreover, the metabolic response of plants to the combination stress differs from that of salt stress or high light alone.

Summary: This study characterized the open chromatin regions (OCRs) in rice pistils and anthers using transposase-accessible chromatin sequencing. The results showed that there were more OCRs in pistils than in anthers, and these OCRs were enriched in gene transcription start sites and tightly associated with gene expression. Transcription factor binding motifs were also found to be enriched at these OCRs, validating their role in gene regulation. Additionally, the study found that the open chromatin of pistils and anthers responded differently to low temperature.

Summary: This study investigated the effect of moderate soil drying on maize production and water use efficiency. The results showed that compared to well-watered conditions, moderate soil drying increased kernel yield, reduced irrigation water consumption, and improved irrigation water use efficiency. Additionally, moderate soil drying enhanced physiological performances, such as the activity of superoxide dismutase and photosynthetic rate, and increased the contents of hormones related to kernel development. These findings suggest that moderate soil drying can achieve the dual goal of increasing food production and saving water in maize cultivation.

The study also showed that segmental duplication was the major driving force for the expansion of GRAS genes in white lupin. Furthermore, the preferential expression of LaGRAS genes in young cluster root and mature cluster roots, particularly in phosphorus (P) acquisition, was confirmed through RT-qPCR analysis.

Summary: Salt stress is a major constraint to plant growth and production. Abscisic acid (ABA) has been shown to play a crucial role in plants under salt stress, and trehalose (Tre) has emerged as an effective osmolyte for inducing salt tolerance. However, the mechanism of interaction between ABA and Tre in rice seedlings under salt stress remains unclear. This study found that exogenous Tre significantly improved salt tolerance in rice seedlings by enhancing the activity of antioxidant enzymes. The expression of the OsNCED3 gene was induced by salt stress. Overexpression of OsNCED3 enhanced salt tolerance, while knockout of OsNCED3 reduced salt tolerance in rice seedlings. Metabolite analysis showed that Tre content was increased in OsNCED3-overexpressing seedlings and decreased in nced3 mutants. The application of both ABA and Tre improved salt tolerance in nced3 mutants compared to wild-type seedlings. The OsTPP3 gene was found to be induced by both ABA and salt treatments. Overexpression of OsTPP3 enhanced salt tolerance, while knockout of OsTPP3 reduced salt tolerance in rice seedlings. Additionally, Tre content was higher in OsTPP3-overexpressing seedlings and lower in tpp3 mutant seedlings compared to wild-type plants. Exogenous Tre application also enhanced salt tolerance in tpp3 mutant plants. Overall, these results demonstrate that salt-induced ABA activates the expression of OsTPP3, leading to an increase in Tre content and improvement in salt tolerance in rice seedlings.
