Summary: Research on the potential of photosynthesis to improve crop yields has led to the identification of breeding targets. The enzyme Rubisco, responsible for CO2 fixation, is inefficient and often limits carbon assimilation in wheat. Two bread wheat lines with similar genetic backgrounds but contrasting Rubisco activity were chosen for detailed study. Phenotypic analysis of photosynthetic traits in these lines showed no difference in Rubisco activity between in vivo and in vitro methods. Additionally, there was no correlation between photosynthetic traits measured in field-grown plants using high-throughput phenotyping. These findings highlight the need to consider the complex interplay between traits and the dynamic environment in breeding strategies for wheat yield improvement.

Summary: Managing sustainable crop production under escalating soil salinity is a major challenge in the coming years. Exogenous application of protectants can ameliorate the adverse effects of salinity on plant growth. This study evaluated the potential role of salicylic acid (SA) and PGPB (Stenotrophomonas sp.) on spinach and soybean cultivars grown under two different salt concentrations. The results showed that 100 ppm salt had more severe effects than 50 ppm salt on the crops and cultivars. Exogenous protectants improved plant growth and yield, as well as osmotic adjustment and antioxidant activity under salt stress. Overall, PGPB was found to be a more effective protectant than SA in reducing salt-induced yield loss.

Summary: This study investigated the fungal endophytic microbiome in wheat from seed to plant to seeds, and examined the effects of host genotype, environment, and fungal sources on shaping the microbiome. The results showed that host genotype, tissue type, and abiotic factors significantly influenced fungal communities, with location-independent effects of host genotype on leaves and roots. Phyllosphere microbiome was mostly affected by location-dependent weather conditions, while root communities were less influenced by abiotic factors.

Summary: The influence of endophytic bacteria Bacillus subtilis (strain 10-4) on the growth, tolerance, and lignin deposition in the roots of Pisum sativum L. seedlings under sodium chloride salinity conditions was studied. The impact of salinity reduced seedling germination energy, viability, root and shoot length, wet and dry weight, and increased proline content and lipid peroxidation level. Pretreatment with strain 10-4 had a positive effect on seedlings in normal conditions and protected them from salinity, improving germination energy, seed viability, root length, and dry mass accumulation under saline conditions. Strain 10-4 also promoted the formation of lateral roots and reduced stress-induced lipid peroxidation and proline content, indicating protection against oxidative and osmotic damage under saline conditions. Furthermore, the strain played an important role in lignification and strengthening of the cell walls, reducing the toxic effect of sodium chloride salinity and providing protection for pea plants.

Summary: This review discusses the use of plant growth-promoting microbes (PGPMs) in wheat production to mitigate the negative effects of drought and herbicide stresses. While the antistress action of PGPMs against drought stress has been well studied, research on the role of PGPMs in the mitigation of herbicide stress, especially in combination with drought, is still in its early stages. The review also highlights the potential of PGPMs in reducing phytotoxic effects of herbicides, pesticide biodegradation, and alternative weed control. Limitations of PGPMs use in the field and future research directions are discussed.

Summary: This study analyzed the effect of nitric oxide (NO) gasotransmitter on wheat plants under salinity conditions. The results showed that 200μM sodium nitroprusside (SNP) could attenuate the negative effects of salinity on leaf area and photosynthetic pigments, stabilize the content of glutathione and ascorbic acid, and improve yield and quality. Therefore, SNP treatment can be an effective approach to protect wheat plants from salinity and enhance yield and quality.
