Summary: Single-cell C-4 (SCC4) plants, such as Bienertia sinuspersici, have fully functional C-4 photosynthesis in a single cell, making them promising materials for genetic engineering in C-3 crops. The responsiveness of the enzymatic antioxidant system, H2O2 and TBARS contents, and redox regulating proteins in the peripheral compartment (PC) and central compartment (CC) chloroplasts of Bienertia sinuspersici were examined under salinity and drought stress. The results showed that PC chloroplasts (PCC) were less damaged by stress compared to CC chloroplasts (CCC), suggesting that PCC is more tolerant to oxidative damage.

Summary: The study investigates the role of Coronatine (COR) in counteracting drought stress by modulating reactive oxygen species (ROS) homeostasis, water balance, and antioxidant regulation in detached maize plants. COR decreases water loss rate and increases ROS production, while antioxidants eliminate the effect of water loss and decrease ROS production induced by COR. The results suggest that COR can improve maize performance under drought stress by modulating ROS homeostasis to maintain water loss rate and antioxidant enzyme activities.

Summary: The UGT85E1 gene plays a crucial role in mediating plant response to drought stress, leading to enhanced tolerance in transgenic rice plants. Its overexpression induces various physiological and metabolic changes in plants under drought conditions. The ectopic overexpression of UGT85E1 in Arabidopsis also results in increased drought tolerance, indicating its potential as a candidate gene for cultivating drought-tolerant crops in both dicots and monocots.

Summary: The study found that by applying sodium nitroprusside and abscisic acid to rice seedlings, their sensitivity to oxidative stress can be enhanced, resulting in different cellular responses in terms of cell water relations and compatible solutes. Different cultivars showed a similar trend of reduced water relations and compatible solutes under salt stress, however, there were differences in the accumulation of polyamines between cultivars.

Summary: Studies on plant responses to combined abiotic stresses are limited, especially in major crop plants. This study evaluated the response of chorismate mutase overexpressor (OxCM) rice line to combined UV light and drought stress. Results showed that OxCM rice maintained growth and vigour under the combined stresses, while wild-type rice had reduced growth. Chorismate mutase (OsCM) reduced oxidative stress and increased flavonoid accumulation, free amino acid accumulation, and ion accumulation (Na, K, and Ca) in response to the stresses.

Summary: Climate change caused by global warming is now affecting agricultural production worldwide. In rice, water limitation due to irregular rainfall in rainfed lowlands during crop growth is a major factor limiting yield. Dry direct-sowing has been suggested as a water-efficient approach to cope with water stress during rice growth, but poor seedling establishment due to drought during germination and emergence remains a problem.

Summary: This study reveals the increased salt tolerance mechanism of heterografted chrysanthemums by using Artemisia annua as rootstock. The roots of heterografted chrysanthemums enrich Na+ under high salt stress, reducing Na+ toxicity in the scion. They also alleviate high Na+ stress through enhanced enzyme activity, downregulation of gene expression related to reactive oxygen species accumulation, accumulation of soluble sugars and proline, and upregulation of gene expression related to heat shock proteins. The leaves of heterografted chrysanthemums respond to low Na+ stress by increasing enzyme activity and soluble sugar and proline contents. Self-grafted and self-rooted plants, on the other hand, cannot integrate these responses to salt stress and exhibit a salt-sensitive phenotype.

Summary: Soil salinization and/or alkalization pose a major constraint to crop production worldwide. Rice cultivation has been recognized as an effective strategy for utilizing SA land, despite the salt-sensitive nature of rice plants. Priming treatment has emerged as a powerful approach to enhance SA tolerance in rice plants by mitigating the damage caused by SA stress.

Summary: Salinity stress increases the accumulation of beta-1,4-galactan in plant cell walls, contributing to salt hypersensitivity. The transcription factors BPC1/BPC2 positively regulate plant salt tolerance by repressing GALS1 expression and beta-1,4-galactan accumulation. Genetically, GALS1 is epistatic to BPC1/BPC2 in controlling salt sensitivity and beta-1,4-galactan levels.

Summary: Global warming and population growth have increased the need for plants to rescue themselves in unfavorable environments to meet food requirements. Stress signal sensing plays a crucial role in determining the appropriate response and ultimately the survival of plants. Plant mitogen-activated protein kinase (MAPK) cascades are key in regulating responses to major environmental stresses.

Summary: In this study, it was found that OsMPK1 in rice plays a crucial role in regulating ABA biosynthesis by phosphorylating OsABA2 protein. OsMPK1 physically interacts with OsABA2 and enhances its stability. Moreover, OsABA2 has feedback regulation on OsMPK1 kinase activity, and together they coordinate the biosynthesis of ABA. It was also discovered that OsABA2 enhances the sensitivity of rice to ABA and improves its tolerance to drought and salt stress.
