Drought Stress in Brassica napus: Effects, Tolerance Mechanisms, and Management Strategies

Maria Batool et al.

Summary: Drought poses serious threats to global crop production, including oilseed crops like Brassica napus L. Various approaches have been used to increase drought tolerance, but there is room for further improvement. Future research should focus on developing genetically engineered rapeseed plants with enhanced drought tolerance.

Morphological, biochemical, and physiological responses of canola cultivars to drought stress

B. Kazemi Oskuei et al.

Summary: Drought stress is a significant factor that affects the growth and productivity of canola plants in arid and semi-arid regions. This study investigated the responses of six canola cultivars to three levels of drought stress. The results showed that root length decreased under drought stress irrespective of the cultivar. Cultivar and drought stress interacted to affect dry weight, height, and leaf area. The cultivars Hyola308 and Sarigol were identified as the most drought tolerant and sensitive, respectively. Drought stress increased proline content and antioxidant enzyme activities, while total soluble sugar content decreased. Hyola308 exhibited higher chlorophyll contents and lower reduction in total soluble sugar compared to Sarigol. These findings suggest that some canola cultivars can alleviate drought stress through proline and antioxidant system enhancement, and Hyola308 possesses a stress management strategy involving higher soluble sugar levels and greenness stability.

Morpho-physiological responses and growth indices of triticale to drought and salt stresses

Soheyla Mohammadi Alagoz et al.

Summary: Salinity and drought stresses significantly reduced chlorophyll contents, total dry matter, leaf area index, relative water content, and grain yield of triticale. However, these stresses led to an increase in soluble sugars, leaf free proline, carotenoid contents, and electrolyte leakage. The flowering stage was found to be more sensitive to water deficit, and soluble sugars and leaf free proline can be used as physiological indicators for drought and salinity tolerance in triticale.

Pseudomonas spp. can help plants face climate change

Antoine Zboralski et al.

Summary: Climate change has various impacts on agriculture, such as droughts, high soil salinity, heatwaves, and floodings, leading to yield losses and food insecurity in affected regions. Plant-beneficial bacteria, particularly those in the Pseudomonas genus, have shown potential in enhancing plant tolerance to these stresses through different mechanisms. This review summarizes the effects of climate change-induced stresses on plants and details the mechanisms used by plant-beneficial Pseudomonas strains to alleviate them, emphasizing the need for targeted research on the stress-alleviating potential of these bacteria.

Achieving abiotic stress tolerance in plants through antioxidative defense mechanisms

Neelam Mishra et al.

Summary: Climate change exacerbates the impact of abiotic stress on plants, negatively affecting their growth, crop yield, and productivity. The imbalance between reactive oxygen species production and detoxification through antioxidant mechanisms is disturbed under different environmental stress conditions. Enzymatic and non-enzymatic antioxidative defense mechanisms help maintain the equilibrium between reactive oxygen species production and elimination. This review focuses on discussing various antioxidative defense approaches and the mechanisms of the involved genes or enzymes to improve plant tolerance to abiotic stress.

The Response to Inoculation with PGPR Plus Orange Peel Amendment on Soybean Is Cultivar and Environment Dependent

Maria Leticia Pacheco da Silva et al.

Summary: The impact of plant growth-promoting rhizobacteria (PGPR) on plant yield is highly variable due to competition with soil microbiota. Previous studies have shown that Bacillus velezensis PGPR strains can utilize pectin as a sole carbon source and that seed inoculation with PGPR and pectin-rich orange peel (OP) can enhance plant growth. However, different soybean cultivars exhibit different responses to the PGPR and OP inoculation, suggesting a cultivar-specific interaction between the plants and microorganisms. Further experiments indicate that environmental factors and molecular interactions may play a significant role in plant responsiveness.

Mitigation of the salinity stress in rapeseed (Brassica napus L.) productivity by exogenous applications of bio-selenium nanoparticles during the early seedling stage

Ali Mahmoud El-Badri et al.

Summary: In recent years, nanoparticles have gained attention as an effective strategy to improve plant growth under salt stress conditions. In this study, bio-SeNPs were used to prime rapeseed seeds, leading to improved expression of aquaporin genes, seed microstructure, germination, growth traits, physiochemical attributes, and mineral uptake under salinity stress. The bio-SeNPs enhanced water uptake during seed imbibition, increased seedlings biomass, promoted rapid seed germination, and improved the efficiency of the plants' defense system. Additionally, the bio-SeNPs modulated the uptake of Na+ and K+, which improved rapeseed growth and prevented oxidative damage due to salt stress.
