Summary: This study investigates the regeneration specificity of thiol-dependent peroxiredoxins and glutathione peroxidase-like enzymes in the cytosol of Arabidopsis thaliana cells. The results demonstrate redundancy and specificity in the redox regulatory network of the cytosol, providing insights into the role of thioredoxins in this process.

Summary: In this study, the regulation mechanism of the HECT-type UPL3 ligase in plants was investigated through multi-omics analysis. It was found that UPL3 plays a critical role in cellular senescence and carbohydrate metabolism. Proteins related to carbon fixation were preferentially ubiquitinated, while proteins related to amino acid synthesis showed reduced ubiquitination in the presence of UPL3 mutation. Furthermore, UPL3 was found to interact with UBP12, BRM, HXK1, and PPC2. These findings reveal a regulatory pattern of UPL3 involving both proteolysis-independent regulation and proteolysis-dependent degradation.

Summary: The biological effects of magnetic fields, especially ultra-high static magnetic fields (UHSMFs), on genomic stability and plant growth have been investigated in this study. The results show that the strength and gradient of UHSMFs have an impact on the molecular spectrum of DNA mutations and can lead to a decrease in seed germination rate.

Summary: This study explores the molecular basis of the abnormal leaf phenotype in the ddc mutant of Arabidopsis thaliana. It demonstrates that misexpression of genes related to leaf fate commitment and morphogenesis, such as CLF and KNAT6, is responsible for the abnormal phenotype. Epigenetic mechanisms, including DNA methylation and histone modifications, are proposed to regulate the expression of these genes during leaf morphogenesis in the ddc mutant.

Summary: The study investigated the potential use of PRIs and a BCA for managing olive leaf spot, with control efficacy over 68% and higher efficacy with dual applications. Laminarin showed the highest control efficacy of 100% and induced different kinetics of gene expression, which could contribute to a better understanding of PRIs in olive culture and the reduction of copper accumulation in the environment.

Summary: The general volatile anesthetic diethyl ether not only blocks sensation and responsive behavior in animals and plants, but also affects gene expression and downstream consequences in the plant Arabidopsis thaliana. The anesthesia causes reprogramming of gene expression, with thousands of genes being upregulated or downregulated. On the protein level, there are also significant changes in protein expression. The most impacted processes include chlorophyll/tetrapyrrole biosynthesis, photosynthesis, and the response to heat stress. The anesthesia also leads to increased cytoplasmic calcium level and cell membrane permeability for ions.

Summary: This study compared the sodium influx in different genotypes of Arabidopsis and observed the changes in cytosolic sodium and calcium concentrations after adding salt through fluorescence microscopy. The results showed that the sodium influx was smaller and transient in the wild type, while it lasted longer in genotypes lacking the Na+/H+ antiporter. Adding salt significantly increased cytosolic calcium concentration, which was related to the external calcium concentration. The study suggests that SOS1 in Arabidopsis is more effective in regulating sodium homeostasis than NHX1.

Summary: The study uncovered a gain-of-function mutant in rice that enhances arsenic tolerance, decreases arsenic accumulation in grains, and improves sulfur and selenium assimilation. This mutant promotes the physical interaction of key proteins in the cysteine synthesis pathway, leading to increased stress resilience and grain quality.

Summary: Plants detect their neighbors through touch, which triggers a calcium response and drives leaf movement. This touch-induced hyponasty mechanism is adaptive and involves an increase in cytosolic calcium concentration in leaf tip trichomes.

Summary: Impairment in OASTLA and OASTLB confers higher sensitivity to selenate in Arabidopsis, and OASTLA, B, and C act as l-Cys and l-SeCys desulfhydrases. The impaired OASTLA and OASTLB resulted in reduced biomass, chlorophyll and soluble protein content, indicating a futile anabolic S-starvation response and increased oxidative stress symptoms. In-gel assays revealed enhanced desulfhydrase activities in response to selenate in OASTLA and OASTLB mutants.

Summary: H2O2 plays a crucial role in plant immune responses, but the mechanisms by which plants sense and regulate H2O2 signaling are poorly understood. This study identifies PRXIIB as the sensor for H2O2 and ABI2 as the target protein, revealing a redox relay mechanism that mediates reactive oxygen species signaling during plant immunity.

Summary: The old12 mutant in Arabidopsis is characterized by a growth defect, spontaneous cell death, activation of plant-defense genes, and early senescence. The cause of this mutant phenotype is a mutation in the P2-TYPE PURINERGIC RECEPTOR 2 (P2K2) gene. P2K2 has been implicated in pathogen tolerance and extracellular ATP sensing. This study demonstrates that old12 is an autoimmune mutant and allelic variation in P2K2 contributes to diversity in Arabidopsis immune responses.

Summary: Ageing in plants is a complex process that involves core cellular processes and primary metabolism, leading to eventual death. Multi-omics studies have revealed correlations between chlorophyll, amino acids, sugars, DNA metabolism, and leaf ageing, while molecular genetic approaches can provide evidence to confirm these correlations.

Summary: Ciborinia camelliae is a fungal pathogen that causes rapid browning and flower drop on ornamental plants of the genus Camellia. The proteins secreted by C. camelliae are necrogenic and proteinaceous in nature, with a functional distribution similar to other related fungi. While some of these proteins might contribute to virulence, they do not determine host specificity.

Summary: Our study is the first to establish a connection between the activity of SAL1/OLD101 against IP3 and the regulation of plant leaf senescence and ROS levels. We found that the developmental leaf longevity is extended in old101 plants, which is accompanied by higher peroxidase activity and decreased H2O2 levels in young plants. The old101 phenotype is caused by a point mutation in SAL1, affecting its activity against IP3. This suggests that the activity of SAL1 against IP3 may play a role in delaying leaf senescence through redox balance regulation.

Summary: This study compared the responses of a New Zealand native plant species, Pachycladon cheesemanii, and Arabidopsis thaliana to different stressors. The findings showed that both species exhibited similar and unique responses to the stressors, with the regulation of glycosinolate, proline, and anthocyanin metabolism playing important roles in mitigating environmental stress.
