Summary: This study investigated the molecular mechanism of sugarcane's response to drought stress (DS) and the potential alleviating effects of chitooligosaccharide (COS). Transcriptome and metabolome analyses were performed on sugarcane under three different treatment groups. The results revealed that DS significantly affected the photosynthesis of sugarcane and COS treatment could alleviate these negative effects. Metabolome analysis identified specific metabolites related to DS, and COS treatment reduced their content. Overall, this study provides valuable insights into the physiological and molecular responses of sugarcane to DS and demonstrates the potential of COS as a protective agent.

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: Exogenous GR24 can alleviate the damage caused by drought stress in apple seedlings by improving leaf chlorophyll contents, photosynthetic parameters, and antioxidant capacity while reducing reactive oxygen species and malondialdehyde production. RNA-seq analysis revealed that exogenous GR24 activates genes associated with stress response, antioxidant enzyme metabolism, calcium signaling, and plant hormone signaling. Therefore, SLs can alleviate drought stress in apples, contributing to improved yield and quality under drought conditions.

Summary: This study characterized the changes in physiology and transcriptome of potatoes under drought stress after pretreatment with 24-epibrassinolide (EBR). The results showed that EBR pretreatment increased ABA content, photosynthetic capacity, and antioxidant enzyme activities, while decreasing intercellular CO2 concentration, relative conductivity, and reactive oxygen species. Transcriptome analysis revealed differentially expressed genes involved in plant hormone signal transduction, starch and sucrose metabolism, circadian rhythm, flavonoid biosynthesis, and carotenoid biosynthesis. These findings provide new insights into the mechanisms by which BRs enhance drought resistance in potatoes.

Summary: This study investigates the effects of low endogenous production of ethylene in sugarcane using RNA interference to silence three genes involved in the ethylene biosynthesis pathway. The findings reveal that reduced ethylene levels result in increased plant growth, accelerated lateral gem germination, and activation of non-enzymatic antioxidant mechanisms. Furthermore, changes in the expression of genes related to growth induction and repression were observed. This study provides valuable insights into the molecular mechanisms behind ethylene responses in sugarcane.

Summary: In acidic soils, toxic aluminum (Al) inhibits root growth of sensitive species, including Citrus plants. This study identified genes that are modulated by Al in the tolerant 'Mandarin' lime rootstock, highlighting the up-regulation of citrate synthase and citrate exudation by MATE channels. Genes related to specialized metabolism, pectin methylesterification, auxin response, defense to biotic and abiotic stresses, cell division, suberin deposition, and nitrate uptake were also up-regulated by Al, providing targets for future research on Al resistance in this rootstock.

Summary: In response to water deficits, plants accumulate proline to alleviate stress. This study investigated the potential role of exogenous proline application or endogenous overproduction in energy dissipation. Wild-type and transgenic tobacco plants were sprayed with proline and subjected to water deficit, and changes in physiology and biochemistry were analyzed. Exogenous proline reduced the negative effects of water deficit on photosynthesis, especially in transgenic plants. Water deficit increased the expression of proline biosynthesis genes but decreased the expression of catabolism genes in transgenic plants. Proline metabolism may act as a compensatory mechanism for energy dissipation in plants under water deficit.

Summary: This study aimed to investigate the role of nickel (Ni) in the metabolism, photosynthesis, and nodulation of cowpea plants. The experiment involved growing cowpea plants in a greenhouse, with different levels of Ni sulfate applied. Several parameters were evaluated, and the results showed that Ni influenced root biomass, seed quantity, and yield. At a concentration of 0.5 mg kg-1 Ni, there was an increase in these parameters, while at 2-3 mg kg-1 Ni, there was inhibition. Additionally, Ni affected photosynthetic pigments, photosynthesis, ureides, and hydrogen peroxide concentration.
