Summary: Proline accumulation is an important response of plants to abiotic stresses, and its significance for drought stress tolerance in crop plants is still unclear. In this study, we investigated the natural variation of the P5CS1 gene in barley and identified new allelic variants associated with proline accumulation. We also introgressed a high proline accumulating allele from a wild barley accession into a cultivar and found that the transgenic line showed higher proline concentrations and better drought stress tolerance. Furthermore, the transgenic line had lower yield-related trait damage under field conditions compared to the cultivar.

Summary: This study cloned and identified the P5CS gene from Stipa purpurea, finding that overexpression of SpP5CS in Arabidopsis thaliana led to increased proline content and better growth under drought stress. SpP5CS-overexpressing A. thaliana showed higher resistance to drought stress compared to the wild type, suggesting that SpP5CS may be a potential target gene for enhancing plant resistance to drought.

Summary: This study aimed to uncover the molecular mechanisms of drought tolerance in chickpea. The physiological response of different genotypes to drought stress was assessed, and RNA-sequencing was performed to identify genes involved in drought tolerance. The study found that genotypes with higher drought sensitivity showed more intense changes in gene expression, particularly in genes related to photosynthesis, hormone response, solute transport, and cell wall properties. These findings will contribute to the development of drought-resistant chickpea cultivars.

Summary: This study investigates the early responses associated with the expression of Arabidopsis dehydration response element binding 1a (DREB1a) in transgenic rice. The findings demonstrate that DREB1a can be co-localized with other genes to enhance multigenic traits. The transgenic rice lines showed improved tolerance to salinity stress and water withholding. RNA sequencing and transcriptome analysis revealed complex transcriptional networks and metabolic reprogramming induced by DREB1a expression. Additionally, potentially novel pathways, such as jasmonate, auxin, and ethylene signaling, were identified, along with the upregulation of multiple transcription factor gene families.

Summary: The overexpression of AtDREB1A gene improves the drought tolerance in transgenic potato. Transcriptome analysis of roots revealed that the expression of genes related to abscisic acid metabolism, receptor-like protein kinases, cytochrome P450, the glycosyl hydrolase family, peroxidase, F-box proteins, and the heat shock protein family were changed significantly, indicating their important roles in enhancing the drought tolerance of AtDREB1A transgenic potato.

Summary: In Tunisia's arid and semi-arid lands, drought stress is the most critical factor limiting agricultural production due to low and irregular precipitation. The scarcity of underground water for irrigation and climate change have further intensified and expanded the aridity. Exploring genotypic variability to identify tolerant genotypes and useful tolerance traits is an efficient and sustainable approach to mitigate drought stress.

Summary: This study aimed to investigate the effects of drought priming on oxidative burst signaling and hormone regulation in the GSH pathway and GSH-based redox control. The results showed that drought priming reduced the oxidative stress and lipid peroxidation during subsequent drought period. Drought priming activated the SA-mediated modulation of the GSH pathway and GSH redox control in antagonism with ABA responses.

Summary: This study demonstrates that supplementation of sulfur can alleviate cadmium toxicity in alfalfa plants by restoring biomass, chlorophyll synthesis, and protein concentration, as well as enhancing photosynthetic kinetics and membrane stability. The mechanisms involve upregulation of sulfate transporters, glutathione and phytochelatin synthesis, and subcellular sequestration of excess cadmium in roots under sulfur surplus conditions. These findings provide valuable insights for developing cadmium-free forage crops through sulfur application and breeding/transgenic experiments.

Summary: It is well established that plants can detect and respond to volatile organic compounds, including those emitted by insects; however, the specific mechanisms underlying this process are still unclear. Research has shown that exposure to (Z)-11-16:Ald can increase plant susceptibility to subsequent herbivory, suggesting alternative ecological effects of detecting insect pheromones. More experiments are needed to determine the specificity of the plant response to this particular aldehyde.
