Summary: This article discusses the impact of stress caused by abiotic factors on plant growth and productivity, especially how drought conditions affect plants by disrupting water balance and ion homeostasis. Plants have evolved transportation systems to survive under drought stress, utilizing channels and transporters such as ABA, proteins, and carbohydrates.

Summary: WRKY transcription factors play key roles in stress responses, growth, and development. Our study on the evolution of WRKYs in cultivated and wild species of Oryza genus revealed prevalence of Group III WRKYs despite breeding differences. Recent duplication events have led to the formation of novel WRKY genes, indicating neofunctionalizations in the same metabolic or response pathway.

Summary: Stomata are epidermal pores that regulate gas exchanges between plants and the atmosphere, and transcriptional regulation plays an important role in stomatal activity. The AtMYB60 transcription factor is identified as a negative regulator of oxylipins synthesis in stomata, influencing stomatal opening. The atmyb60-1 mutant shows reduced stomatal opening and increased levels of 12-oxo-phytodienoic acid (12-OPDA), jasmonic acid (JA), and jasmonoyl-l-isoleucine (JA-Ile) in guard cells. Furthermore, 12-OPDA triggers stomatal closure independently of JA and cooperatively with abscisic acid (ABA) in atmyb60-1. This study highlights the importance of oxylipins metabolism in stomatal regulation and identifies AtMYB60 as a transcriptional integrator of ABA and oxylipins responses in guard cells.

Summary: The study investigates the role of root ABA in maize's adaptation to soil drought. It shows that root ABA content and activities of ABA biosynthesis enzymes increase with decreasing soil water potentials. Parameters such as leaf photosynthetic rate, root traits, and kernel yield exhibit varying responses to soil drying severity.

Summary: This study investigated the responses of two tomato genotypes to drought stress and found that WT exhibited more pronounced stomatal closure, ABA biosynthesis, and proline accumulation compared to flacca. FTIR analysis revealed changes in cell wall components in flacca.

Summary: Plant water relations are crucial for crop response to soil water availability. Root-to-shoot signals regulate shoot physiology, while shoot-to-root hormonal signaling plays a role in regulating root growth and function. The transportation of hormones can influence each other's synthesis and impact, which adds to the complexity of these signaling systems.

Summary: Tall fescue, known for its drought resistance, may benefit from its seed-borne fungal symbiont Epichloe coenophiala. Genes in the crown show higher differential expression, potentially aiding in survival of the apical meristems.

Summary: This study investigates the mRNA expression levels of 16 OGs and 20 TGs involved in key signaling pathways in Wilms' tumor cases and identifies certain genes that are significantly up-regulated or down-regulated. These findings are important for the diagnosis of Wilms' tumor, but further validation in a larger sample size is needed.

Summary: The evolution of the four-segmented limb in therians is accompanied by changes in development and sensorimotor control. By deleting the Wt1 gene in a specific group of interneurons in the spinal cord of mice, we found that this perturbation affects the coordination of limb movements, particularly in the forelimbs. Interestingly, these effects are similar to locomotor deficits observed when sensory feedback is impaired.
