Summary: This study aimed to investigate the fluctuations in metabolite profiles of lentil genotypes with contrasting drought tolerance, identifying differences in metabolite accumulation between tolerant and susceptible genotypes. Results suggest that the metabolic responses of lentil to osmotic drought stress are strongly influenced by genotypic factors.

Summary: This study aimed to investigate the effects of drought stress on the accumulation of cadmium and zinc in Chromolaena odorata. The results showed that drought stress caused a decrease in water content in the plant tissues, leading to the accumulation of Cd and Zn mainly in the roots.

Summary: The study found significant variation in different root traits among lentil genotypes, with total root length, surface area, root volume, and root diameter being correlated to drought tolerance. Through research on 11 drought-tolerant genotypes, further exploration in lentil breeding programs can be conducted.

Summary: Ideotype breeding is an essential approach for selecting ideal plant traits to improve yield and mitigate drought stress. This study identified desirable phenological and physiological traits for lentil cultivars and designed new ideotypes with improved traits. The results showed that a combination of genetic traits can lead to a yield advantage of around 10% compared to current cultivars. Additionally, the study highlighted the importance of agronomic practices, such as early sowing and residue retention, in reducing the impact of drought.

Summary: This study aimed to investigate the relationship between leaf rolling and soil water content, as well as the influence of vapor pressure deficit (VPD) on leaf rolling. The results showed that high VPD alone does not readily induce leaf rolling, and leaf rolling is proportional to the extent of soil drying.

Summary: Drought is a common abiotic stress that affects the growth and productivity of maize. In this study, 27 elite maize inbred lines were evaluated for their drought tolerance. The results showed that a large proportion of inbred lines selected from specific breeding populations demonstrated higher drought resistance and could be categorized as high-yield drought-resistant types. This study provides valuable insights for improving drought resistance and breeding new varieties of maize.

Summary: This study analyzed the changes in physiological and biochemical indicators of drought-tolerant and drought-sensitive wheat during drought and re-watering, and identified 7 indicators to characterize wheat tolerance to drought. The results showed that the physiological responses of drought-tolerant wheat recovered better than drought-sensitive wheat.

Summary: This study demonstrates that overexpression of JsFLS5 in walnut callus enhances flavonoid synthesis and increases salt tolerance by modulating the expression of genes associated with flavonoid synthesis. The overexpressing callus also exhibits lower levels of oxidative damage, higher antioxidant enzyme activity, and reduced Na+/K+ ratio. These findings provide a novel perspective on the role of JsFLS5 in the response to abiotic stress in J. sigillata.

Summary: This study presents a nonstationary framework for drought propagation analysis and determines drought propagation thresholds. The results show that the nonstationary models provide better fitting performance for drought indices and the Clayton copula function with dynamic parameters accurately describes the linkages between two types of drought. The analysis also reveals the varying trend of watershed drought tolerance in different months.

Summary: Pearl millet is a C-4 crop grown in the tropics and subtropics of the Indian subcontinent and sub-Saharan Africa for its grain and stover. The increasing intensity of drought due to climate change necessitates a greater focus on breeding for drought tolerance in pearl millet. Advances in genomics and molecular biology have provided tools to enhance the development and delivery of high-yielding and drought-tolerant cultivars.

Summary: Studies suggest that drought priming can enhance wheat's tolerance to drought, with the root apex playing a crucial role in this process. Drought priming augments root growth under drought conditions by regulating the levels of protective proline and glycine betaine. Further investigations reveal that different zones of the root apex exhibit varying responses in gene expression.

Summary: A study on soil salinity and lentil productivity discovered that tGBS method revealed the highest number of SNP variants and markers were evenly distributed in the genome. A genome-wide association study using a mixed linear model found significant marker-trait associations on Chromosomes 2 and 4, with candidate genes related to potassium transporters. Detailed mineral composition analysis revealed the salt tolerance mechanism in lentil, with tolerant accessions containing Na+ ions in root tissues rather than transporting them throughout the plant. Pedigree analysis identified two parental accessions as key sources of tolerance.
