Summary: Dehydrins and aquaporins play crucial roles in plant growth and stress responses. The proteins MsDHN1 and MsPIP2;1 were found to interact with a membrane-anchored MYB protein, MsmMYB, under normal conditions. These proteins positively regulate alfalfa's tolerance to water deficiency. Water deficiency causes phosphorylation of MsPIP2;1, leading to the release of the C terminus of MsmMYB from the plasma membrane and its translocation to the nucleus. Once in the nucleus, the C terminus of MsDHN1 interacts with the C terminus of MsmMYB, promoting its transcriptional activity in response to water deficiency. Overexpression of MsmMYB and its C-terminal fragment down-regulates the expression of MsCESA3 but up-regulates the expression of MsCESA7, resulting in enhanced drought tolerance in transgenic hairy roots.

Summary: The study analyzed the response of two rice genotypes to recurrent drought, with results showing that both genotypes reduced stomatal conductance and increased ABA concentration under water deficit conditions. After rehydration, ABA levels decreased, especially in the lowland genotype, and ABA-GE concentration increased. The study indicates that ABA metabolism is altered depending on the genotype and pre-exposure to stress can modify adaptive responses in rice varieties.

Summary: This study aimed to determine the metabolic differences in two rice genotypes, one drought-susceptible (IR64) and one drought-tolerant (Azucena). The results showed that Azucena may evade water stress by increasing the lateral root system growth, while IR64 relies on cell wall thickening to tolerate stress. Significant differences in metabolites were observed in both genotypes, with metabolites related to secondary metabolism, amino acid metabolism, nucleotide acid metabolism, and sugar and sugar alcohol metabolism. Potential metabolic markers for drought tolerance were identified, which can be used for the selection of drought-tolerant rice genotypes.

Summary: This study explores the potential of the CERES-Rice model as a decision support tool (DST) in identifying drought-tolerant high-yielding upland rice genotypes. The experiments conducted showed that the model accurately predicted grain yield under different irrigation treatments and the identified genotypes had lower stress indices and higher water use efficiency, indicating their drought tolerance. The results support the use of the model as a DST in rice breeding programs for selecting drought-tolerant high-yielding genotypes.

Summary: This study aims to determine the salt stress tolerance of different wild pear genotypes and clonal pear rootstocks under in vitro conditions. The results showed that OHxF 333, AN-19, QA, and AH-3 exhibited high survival rates at high salt concentrations. The number of shoots decreased with increasing salt concentration, while shoot length remained similar to the control. Genotypes AH-3, OHxF 333, QA, and AN-19 showed earlier response to salinity stress, and were further evaluated for antioxidant activity and mineral elements. AH-3 and QA showed the highest levels of certain antioxidant activities at high salt concentration. This study provides insights into the salt stress response of Pyrus spp. and Cydonia oblonga genotypes used for pear rootstocks.

Summary: Trichoderma biopriming can enhance rice growth in drought-stressed soils by triggering various plant metabolic pathways. Transcriptomic analysis revealed that a multitude of genes were differentially expressed in rice cultivars under drought stress and Trichoderma harzianum treatment, with significant upregulation of genes related to photosynthesis and antioxidation. The Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis highlighted metabolic pathways as the most enriched, suggesting a comprehensive molecular programming effect of T. harzianum biopriming in delaying drought stress in rice cultivars.

Summary: Drought stress is a major challenge for global rice production, and breeding drought-tolerant rice genotypes is an important strategy. This study evaluated the drought tolerance of rice through biochemical, anatomical, and molecular aspects, and selected promising crosses with higher antioxidant capabilities and anatomical characteristics. Molecular analysis also identified two crosses as the most suitable for water conservation, based on their gene expression and similarity values.

Summary: Root system architecture (RSA) plays a critical role in improving nutrient and water uptake and maintaining crop yield under both optimal and drought conditions. Sequencing of small RNAs in the meristematic root tips of rice genotypes Azucena and IR64 revealed changes in miRNA expression patterns under drought stress. Different target genes were predicted for the differentially expressed miRNAs (DEMs) in Azucena and IR64, suggesting distinct mechanisms for coping with drought stress. Azucena exhibited upregulation of miRNAs related to root elongation, root system development, and stress adaptation, while IR64 promoted thickening of cell walls for insulation purposes.

Summary: Climate change has led to severe drought, impacting global crop production. Broomcorn millet, which is a drought-tolerant crop known for its short life cycle and high water use efficiency, is commonly used in water-saving agriculture. This study evaluated the drought tolerance of 300 broomcorn millet varieties and found that drought stress decreased photosynthetic capacity and triggered transcriptome reprogramming. Additionally, melatonin treatment enhanced drought resistance in the broomcorn millet varieties.
