Summary: The main constraint on rice cultivation in the Mediterranean area is limited irrigation and high water consumption. Rice is highly sensitive to drought conditions, but the application of salicylic acid (SA) can alleviate this effect. This study found that irrigation, cultivar, and SA concentration significantly affect plant growth, leaf photosynthetic pigments, and yield. Under drought conditions, grain yield and most studied traits were reduced.

Summary: This paper mainly discusses the role of salicylic acid (SA) in both biotic and abiotic stresses of plants. SA enhances plant immunity by regulating gene expression and participating in signaling pathways, mitigates the negative effects of abiotic stresses, and improves yield-related photosynthetic indexes, thereby increasing crop yield under stress.

Summary: Drought stress is a significant limiting factor for soybean growth and production globally. Improving genetic traits related to water and nutrient uptake efficiency is crucial for enhancing tolerance and promoting sustainable and resilient production. This review focuses on identifying quantitative traits and genes associated with water and nutrient absorption to enhance understanding of drought tolerance mechanisms in soybean. It also highlights the importance of genes controlling root system architecture as targets for breeding strategies to improve drought tolerance in soybean, discussing candidate genes regulating key root traits and responses to water stress. Progress in understanding specific genes like GmACX1, GmMS, and GmPEPCK is discussed in relation to developing a system-based platform for genetic enhancement of drought tolerance in soybean.

Summary: Salt stress is a major factor contributing to reduced yield in mungbean, but the growth hormone salicylic acid (SA) can enhance salt tolerance and improve agricultural yield. This study investigated the effects of SA and salt stress on photosynthesis parameters and antioxidant enzymes in mungbean plants. The results showed that Var. 145 was more sensitive to high salt concentrations, while Var. 155 had higher chlorophyll concentrations and better antioxidant enzyme activity. SA-treated Var. 155 exhibited better salt tolerance and osmoprotectant responses compared to Var. 145. The efficacy of SA in improving salt tolerance in plants is of great interest for future research.

Summary: This study examined the potential role of endogenous salicylic acid (SA) in regulating endophytic Bacillus subtilis-mediated drought tolerance in wheat. The results showed that B. subtilis 10-4 promoted endogenous SA accumulation and the expression of SA-dependent defense genes, leading to enhanced drought tolerance in wheat seedlings. However, the effects of B. subtilis treatment were abolished by inhibiting SA synthesis, highlighting the importance of SA as a hormone intermediate in triggering the defense responses.

Summary: This study reveals that the oxidation of GmNTL1 during salt stress promotes its relocation and transcriptional activity, enhancing soybean's resilience against salt stress. The H2O2-mediated posttranslational modification on cysteine plays a crucial role in the signal transduction pathway, activating downstream genes involved in ROS production and salt tolerance. Transgenic overexpression of GmNTL1 leads to increased H2O2 levels and improved salt tolerance in soybean.

Summary: This study investigated drought tolerance mechanisms in clusterbean by analyzing physiological, biochemical, and transcriptome data of tolerant and sensitive genotypes under drought stress. The tolerant genotype maintained higher relative water content, pigment concentrations, and net photosynthesis compared to the sensitive genotype. Enhanced enzymatic antioxidant activity and higher ratios of antioxidant molecules were observed in the tolerant genotype. Transcriptome analysis revealed differential expression of genes related to starch and sucrose metabolism in the tolerant genotype. Overall, these findings contribute to our understanding of drought tolerance mechanisms in clusterbean.

Summary: Medicinal plants, particularly herbs, have been crucial for human health due to their accessibility and affordability. While angiosperms are commonly used in herbal formulations, there is potential in using gymnosperms, a group of non-flowering plants with limited diversity and distribution. However, research on the phytochemistry of gymnosperms is scarce. This review aims to highlight the importance of gymnosperms, specifically in homeopathy, and encourages future researchers to explore their potential for developing novel remedies.

Summary: The SARS-COV-2 pandemic is causing havoc worldwide, with uncertain effectiveness of immunization against new variants. Herbal remedies, particularly liverworts, are emerging as a promising preventive measure due to their antiviral potential and antioxidant properties. However, the vast majority of liverworts remain unknown, making research on their phytochemical profiles and bioactivity essential. Therefore, a study was conducted on the commonly growing liverwort Plagiochasma rupestre to evaluate its potential in herbal treatments and chemical manufacturing.

Summary: This study investigates the methylome, transcriptome, and morpho-physiological responses of two Arabidopsis thaliana populations to elevated [CO2]. The results show variations in DNA methylation at the local level depending on the population origin, but no change in global methyl cytosine (mC) content. The differentially methylated genes belonged to distinct functional categories, with more genes related to methylation machinery down-regulated in the high elevation population. Understanding the epigenetic response to e[CO2] may inform future crop improvement strategies.

Summary: This study investigates the geographic distribution and yield of wheat under future climate change scenarios using global General Circulation Models (GCMs) and Free Air CO2/O3 Enrichment (FACE) experiments. The results show a reduction in climatically suitable areas for wheat cultivation and differential impacts of elevated CO2, O-3, and temperature on wheat yield. Only two wheat cultivars showed no yield decline, while the majority exhibited significant declines. The study concludes that the future of wheat cultivation in India is bleak.

Summary: This study investigated the effect of calcium chloride (CaCl2) treatment on GABA accumulation in fresh-cut cantaloupe and the underlying mechanisms. The results showed that CaCl2 treatment increased GABA content and the activities of GAD and SSADH enzymes, while reducing glutamate content and GABA-T activity. Additionally, CaCl2 treatment upregulated the expressions of CmCML11 and CmCAMTA5, as well as several GABA shunt genes, through the transcriptional activation by CmCAMTA5. Furthermore, the interaction between CmCML11 and CmCAMTA5 enhanced the transcriptional activation of GABA shunt genes. Overall, this study reveals that CaCl2 treatment promotes GABA accumulation in fresh-cut cantaloupe through the combined effect of CmCML11 and CmCAMTA5 in regulating the expressions of GABA shunt genes.

This study investigated the effects of Se(IV) on root exudates, root morphology, root endogenous hormones, and Cd uptake efficiency in rice under Cd stress. The results showed that Se(IV) significantly reduced Cd concentrations in shoots and roots, and decreased Cd uptake efficiency via root hairs. Se(IV) also affected root morphology, root exudates, and the synthesis of hormones like IAA and JA. However, transcriptome analysis revealed no upregulated differentially expressed genes (DEGs) in IAA synthesis.
