Summary: Salinity stress adversely affects plant growth and development, limiting crop productivity. Plants adapt to salt stress by synthesizing, signaling, and regulating osmolytes and phytohormones. Osmolytes stabilize osmotic differences and facilitate protein functioning and stress signaling. Phytohormones play critical roles in plant adaptation to salt stress by regulating osmolyte accumulation and minimizing detrimental effects.

Summary: Jasmonate has dual impacts on the osmotic and ionic components of salt stress in rice. It is required for abscisic acid-mediated water deprivation responses but inhibits Na(+) retention in roots, leading to leaf damage. This study investigates the dynamics of JA metabolism and signaling in rice and identifies contrasted contributions of JA signaling to different sectors of the salt stress response in the plant.

Summary: In this study, researchers found that BnA.JAZ5, a key genetic regulator in the jasmonate signaling pathway, plays a role in rapeseed response to drought. BnA.JAZ5 overexpression in rapeseed plants increased drought susceptibility and reduced seed germination under ABA treatment. The study also revealed a possible crosstalk between the Jasmonate and ABA signaling pathways in regulating drought response in rapeseed.

Summary: Plants face environmental threats during their life cycle, and global warming poses a severe existential threat to them. However, plants adapt by developing strategies coordinated by plant hormones, including ethylene and jasmonates (JAs), to regulate stress responses and produce secondary metabolites. Understanding the mechanisms by which plant hormones and secondary metabolites respond to abiotic stress is crucial for improving plant adaptability to climate change without compromising yield and productivity.

Summary: This study reveals that the tomato WRKY transcription factor WRKY57 negatively regulates salt stress response by attenuating the transcription of salt-responsive genes and an ion homeostasis gene. The VQ-motif containing proteins, SlVQ16 and SlVQ21, interact with WRKY57 and modulate tomato's resistance to salt stress, with SlVQ16 acting positively and SlVQ21 acting negatively. The SlWRKY57-SlVQ21/SlVQ16 module is also involved in the jasmonate pathway.

Summary: In this study, we found that overexpression of the MpSnRK2.10 gene alleviated the growth restriction caused by salt stress in apple plants. The overexpression lines showed reduced electrolyte leakage, malondialdehyde content, and reactive oxygen species production, while having increased chlorophyll content, superoxide dismutase activity, photosynthetic capacity, and accumulation of several amino acids under salt stress. The overexpression lines also accumulated less Na+ and up-regulated genes involved in Na+ balance compared to wild-type plants. Overexpression of MpSnRK2.10 altered the role of the ABA pathway in response to salt stress.

Summary: Serotonin and melatonin, two types of indolamines present in various organisms, have been shown to have strong bioregulatory effects in plant tissues. While the stress-relieving effects of melatonin have been well-documented, the impact of serotonin on plant stress physiology has received limited attention in current literature. In this study, the researchers investigated the effects of exogenous serotonin on tomato seedlings under severe salt and drought stresses. The results showed that serotonin application led to decreased tissue MDA contents and ion leakage levels, as well as increased relative water contents. Additionally, serotonin affected the expression of various stress-related genes, including ACS2, FeSOD, CAT2, GR1, and P5CS.

Summary: The study of the MdARF8 gene in apple reveals its involvement in the regulation of plant growth and development through jasmonate signaling. Ectopic expression in Arabidopsis showed that MdARF8 reduces the sensitivity to MeJA and alleviates leaf senescence and taproot elongation inhibition. MeJA treatment partially recovers the dysplastic phenotype of transgenic Arabidopsis root hair. This study provides valuable insights into the functional characterization of ARF8 and the crosstalk between jasmonate and auxin in apple.

Summary: Methyl jasmonate (MeJA) is a volatile hormone that acts as a signal in response to external stresses in plants. It has been shown to enhance fruit antioxidant capacity and phenolics content, leading to extended shelf-life, improved quality, and reduced chilling injury. Additionally, postharvest application of MeJA can alter volatiles pattern and enhance the innate disease resistance of fruits against pathogenic fungi.

Summary: Plants use a two-layered immune system to defend themselves against pathogens. The first response, pattern-triggered immunity (PTI), is activated by recognizing microbe-associated molecular patterns (MAMPs). Some plants have resistance (R) proteins that recognize specific effectors, leading to the activation of effector-triggered immunity (ETI). Our study shows that WRKY22 and WRKY25 are positive regulators of plant immunity in tomato.

Summary: Arsenic, a metalloid, is mainly found in soil and water. Excessive levels of arsenic are toxic to living organisms, making it a global concern. Humans can absorb arsenic through polluted water and contaminated food, while plants are more susceptible to arsenic poisoning due to their inability to move and their reliance on roots for nutrients. Arsenic competes with phosphorus and disrupts physiological processes in plants, leading to decreased yield and biomass. Various mitigation strategies, including agronomic practices and genetic manipulation, can help reduce arsenic absorption by plants and address the negative effects.

Summary: Plant Glycogen Synthase Kinases (GSKs) play a crucial role in regulating various physiological processes by enabling crosstalk among signaling pathways. However, the mechanisms that regulate the expression of GSK genes during plant development and stress responses are still largely unknown. This study provides a detailed analysis of GSK promoters in rice and Arabidopsis, as well as characterization of expression profiles under different conditions. The results offer valuable insights into the regulatory mechanisms and may serve as a reference for future research in other plant species.

Summary: This study examined the relationship between damage traits in teak plants caused by a soil-borne pathogen and the spectral reflectance of diverse clones. The results showed that near-infrared spectroscopy and partial least squares regression analysis could effectively predict the magnitude of damage in teak plants. This study provides valuable information for teak breeding and conservation efforts, but long-term observation is essential to evaluate the sustainability of teak genotypes.

Summary: Cereal crops play a significant role in human consumption and animal feed, but face challenges from climate change and population expansion. Gene-editing technologies, such as CRISPR/Cas9, offer a potential solution to develop stress-tolerant and high-yielding cereal varieties. However, there are challenges to overcome, including time-consuming processes, limited genotypes for transformation, and restrictive regulations on genetically modified organisms (GMOs).
