Summary: This study evaluated the response of tomato plants to water scarcity by analyzing changes in leaf reflectance and identifying spectral reflectance indices (SRIs) for the early detection of drought stress. The researchers found 12 SRIs that showed significant differences between treatments, with 6 of them already significantly different within 7 or 9 days after the experiment started. These findings suggest that these SRIs could be used as promising proxies for the early detection of invisible responses to drought onset.

Summary: The majority of agricultural land experiences abiotic stress which leads to significant reduction in agricultural yields. Understanding plant defense mechanisms against stress and applying this knowledge is crucial for sustainable agriculture. This review focuses on the current findings in plant resistance to drought, heat, salinity, and low temperatures, and also highlights the importance of primary and secondary metabolites. Transcriptomic studies on Arabidopsis demonstrate that different abiotic stressors induce different signals and effects in gene expression, but there are still genes that are regulated similarly under most stressors. The review also provides information on the response to abiotic stress in major European crop plants.

Summary: Drought and salinity have negative effects on plant growth and productivity, but the anthocyanin biosynthesis system can activate plant stress-tolerance mechanisms and enhance drought and salt tolerance. This review focuses on the molecular and biochemical mechanisms of anthocyanins in acquired tolerance to drought and salt stresses, as well as the role of abscisic acid and abscisic-acid-miRNA156 in regulating drought-induced anthocyanin production. Additionally, it summarizes the research progress on transcription factors involved in anthocyanin biosynthesis and the development of salt and drought tolerance. Finally, the recent progress in using modern gene manipulation technologies to develop anthocyanin-enriched plants with enhanced tolerance to drought and salt stresses is discussed.

Summary: Autophagy is an important protein degradation system that plays a crucial role in maintaining cellular homeostasis. The involvement of ATG8, a core member of autophagy, in plant tolerance to abiotic stress is of great interest. This study found that CaATG8e negatively regulates the heat tolerance of pepper by suppressing the expression of heat shock response-related genes, thus providing insights into the molecular mechanisms of plant responses to heat stress.

Summary: Salt and drought stress are major causes of crop losses worldwide. Various strategies, including irrigation, traditional breeding, genetic engineering, and plant growth-promoting bacteria (PGPB), can be employed to enhance crop tolerance to these stresses. PGPB employ mechanisms such as synthesis of growth-promoting hormones, antioxidant enzymes, osmolytes, and nitrogen fixation to improve plant growth and alleviate stress.

Summary: Plant growth-promoting rhizobacteria (PGPR) enhance plant tolerance to abiotic stresses by secreting exopolysaccharides (EPS), including salinity, drought, temperature, and heavy metal toxicity. Studying the mechanisms of EPS action and the impact of abiotic stresses on bacterial EPS production can provide a better understanding of the interactions between plants and microbes.

Summary: The impact of global climate change on food security is a growing concern due to extremes of temperature and water scarcity. This review discusses how endophytes, microbes that live within plants without causing disease, can help plants tolerate drought stress. The review explores the symbiotic relationship between plants and endophytes and the molecular and physiological mechanisms that endophytes use to confer stress tolerance to their hosts. Omics-based techniques, such as comparative genomics and functional genomics, have advanced our understanding of the molecular basis of endophyte-mediated drought tolerance in plants.

Summary: In the natural environment, plants are exposed to various abiotic and biotic stresses simultaneously or sequentially. However, little is known about the combined effects of these stresses on plants. This study investigated the effects of soil compaction and drought on maize hybrids through measurements of gas exchange, chlorophyll fluorescence parameters, leaf area, leaf greening, leaf water deficit, leaf water potential, and membrane injury. The results showed that high soil compaction led to a decrease in most measured traits, while drought had a greater impact, especially on sensitive hybrids. The study also revealed the genetically determined variability of tolerance to these stresses and suggested potential criteria for hybrid selection.

Summary: In climate change scenarios, the application of silicon (Si) compounds in agriculture has gained attention due to their beneficial effects on plant growth and development under adverse environments. Si enhances plant antioxidant defenses and reduces oxidative stress, and biofortification techniques can be used to improve a plant's capacity to accumulate Si and reduce biotic and abiotic stresses. Genetic engineering to identify novel genes involved in Si transport and modulate their expression level is being considered as a way to prevent crop damage and reduce the use of toxic pesticides, herbicides, and fungicides.

Summary: Stomatal closure can be induced by both abscisic acid (ABA) and polyamines, but the physiological functions of ABA and polyamines in inducing stomatal closure are still unclear. In this study, it was found that both ABA and polyamines can induce stomatal closure through similar signaling components. However, polyamines partially inhibit ABA-induced stomatal closure by activating antioxidant enzymes to eliminate the increase in hydrogen peroxide (H2O2) induced by ABA. These findings suggest that polyamines may be used as potential regulators to increase photosynthesis under mild drought stress.

Summary: Members of the SnRK2 family are plant-specific serine or threonine kinases that play a crucial role in plants' response to abiotic stresses. They interact with the phytohormone abscisic acid (ABA) to regulate plant organ development. Recent research has shown the synergistic relationship between SnRK2 and ABA signaling in stress response.
