“…These changes can be ascribed to the protein hydrolysis or oxidative inhibition of protein synthesis, causing Pro buildup. Reviewing previous literature, there are references concerning to the accumulation of dehydrin proteins under drought conditions in sensitive as well as tolerant cultivars of different crops like wheat (Nemati et al, 2019), soybean (Arumingtyas & Savitri, 2013), and grapevine (Yang et al, 2012). The accumulation of dehydrin‐like proteins can be identified in the radicular and leaf tissues of plants exposed to water stress, which likely defended them from suffering more dehydration injury.…”

Drought stress, which causes a decline in quality and quantity of crop yields, has become more accentuated these days due to climatic change. Serious measures need to be taken to increase the tolerance of crop plants to acute drought conditions likely to occur due to global warming. Drought stress causes many physiological and biochemical changes in plants, rendering the maintenance of osmotic adjustment highly crucial. The degree of plant resistance to drought varies with plant species and cultivars, phenological stages of the plant, and the duration of plant exposure to the stress. Osmoregulation in plants under low water potential relies on synthesis and accumulation of osmoprotectants or osmolytes such as soluble proteins, sugars, and sugar alcohols, quaternary ammonium compounds, and amino acids, like proline. This review highlights the role of osmolytes in water-stressed plants and of enzymes entailed in their metabolism. It will be useful, especially for researchers working on the development of drought-resistant crops by using the metabolic-engineering techniques.

“…These proteins could also work together to maintain the dynamic balance of ROS levels and thereby avoid the oxidative damage incurred by plants. This type of coordination occurs in alkaligrass [51], rapeseed [52] and cassava [53], perhaps due to the fact that enzyme activity is regulated by post-translational modifications [54]. Finally, POD can also contribute to how plants respond to drought stress [5].…”

Drought stress can dramatically impair woody plant growth and restrict the geographical distribution of many tree species. To better understand the dynamics between the response and mechanism of Cupressus gigantea to drought and post-drought recovery, a comparative analysis was performed, relying on physiological measurements, RNA sequencing (RNA-Seq) and two-dimensional gel electrophoresis (2-DE) proteins. In this study, the analyses revealed that photosynthesis was seriously inhibited, while osmolyte contents, antioxidant enzyme activity and non-enzymatic antioxidant contents were all increased under drought stress in seedlings. Re-watering led to a recovery in most of the parameters analyzed, mainly the photosynthetic parameters and osmolyte contents. Transcriptomic and proteomic profiling suggested that most of the differentially expressed genes (DEGs) and differentially expressed proteins (DEPs) were specifically altered, and a few were consistently altered. Drought induced a common reduction in the level of DEGs and DEPs associated with photosynthesis. Notably, DEGs and DEPs involved in reactive oxygen species (ROS) scavenging, such as ascorbate oxidase and superoxide dismutase (SOD), showed an inverse pattern under desiccation. This study may improve our understanding of the underlying molecular mechanisms of drought resistance in C. gigantea and paves the way for more detailed molecular analysis of the candidate genes.

“…When plants experienced drought stress, SPS catalyzed the conversion of uridine diphosphate-glucose and fructose 6-phosphate into sucrose. Nemati et al found that SPS changed in abundance after being exposed to drought stress in wheat seedlings [48]. Other studies showed that drought treatment markedly increased SPS activity [49,50].…”

Drought is one of the significant threats to the agricultural sector. However, there is limited knowledge on the plant response to drought stress and post-drought recovery. Pandanus amaryllifolius, a moderate drought-tolerant plant, is well known for its ability to survive in low-level soil moisture conditions. Understanding the molecular regulation of drought stress signaling in this plant could help guide the rational design of crop plants to counter this environmental challenge. This study aimed to determine the morpho-physiological, biochemical and protein changes of P. amaryllifolius in response to drought stress and during recovery. Drought significantly reduced leaf relative water content of P. amaryllifolius. In contrast, relative electrolyte leakage, proline and malondialdehyde contents, and the activities of antioxidant enzymes in the drought-treated and recovered samples were relatively higher than the well-watered sample. The protein changes between drought-stressed, well-watered, and recovered plants were evaluated using tandem mass tags (TMT)-based quantitative proteomics. Of the 1,415 differentially abundant proteins, 74 were significantly altered. The majority of proteins differing between them were related to carbon metabolism, photosynthesis, stress response, and antioxidant activity. This is the first study that reports the protein changes in response to drought stress in Pandanus. The data generated provide an insight into the drought-responsive mechanisms in P. amaryllifolius.
