Summary: Globally, powdery mildew (PM) caused by Erysiphe pisi is a major disease of peas, with three resistant genes identified so far, er1 being the most widely deployed. Allelic variations of the er gene and linked DNA markers have provided breeders with effective tools for developing PM-resistant pea cultivars through marker-assisted selection. Exploiting this information will be crucial for future targeted PM resistance breeding in Pisum.

Summary: Spray-induced gene silencing (SIGS) is a promising tool for crop pest protection by utilizing exogenously applied double-stranded RNA to reduce pest target gene expression. This study optimized SIGS methods for powdery mildew fungi and identified important gene targets and processes for powdery mildew control. The efficacy of SIGS on powdery mildew makes it an exciting prospect for commercial powdery mildew control.

Summary: Research shows that intercropping pea with barley or faba bean at a 50:50 ratio can significantly reduce powdery mildew infection, while intercropping with wheat does not have a similar effect. Mixing resistant and susceptible cultivars also decreases powdery mildew infection in pea.

Summary: Grain legumes, such as peas, have desirable properties for agriculture, but their cultivation on a large scale faces challenges due to susceptibility to diseases, including powdery mildew. This review examines current methods of controlling powdery mildew, including fungicides and biological agents, with a focus on the plant genetic mechanisms of resistance. The study highlights the naturally occurring resistance in garden peas and discusses the potential for introducing this resistance into other important legume crops.

Summary: This study evaluated the impact of different fungicide spray schedules on powdery mildew severity and crop yield through a meta-analytic approach. The findings suggest that delaying the first spray can still protect crop yield, and additional sprays may not always be necessary, reducing costs and potential environmental effects.

Summary: This study compared the hormonal profiles in tolerant and susceptible grape varieties upon infection with Erysiphe necator. The results showed that tolerant varieties had a specific hormonal combination that allowed for a faster and more efficient response against powdery mildew. The balance of different phytohormones plays a crucial role in determining tolerance or susceptibility.

Summary: This study evaluates the effectiveness of eight combinations of natural products with chitosan oligomers in controlling powdery mildew. The study finds that combinations of chitosan oligomers with secondary metabolites of Streptomyces spp. and chitosan oligomers with hydrolyzed gluten show the best results. These formulations have comparable efficacy to conventional antifungals and provide an interesting alternative for disease control.

Summary: A strong and rapid resistance to powdery mildew was found in a grapevine, which can effectively stop over 97% of the pathogen's infection attempts. The resistance is effective on various parts of the plant and against different strains of the pathogen. The resistance gene (REN12) was identified and mapped to a specific location on chromosome 13, explaining most of the observed phenotypic variation.

Summary: Gene expression analysis revealed that RBgh2 plays a role in cAMP/G-protein-coupled signalling and innate immunity in barley powdery mildew adult plant resistance. RBgh2 is a major effect adult plant resistance gene in barley powdery mildew, showing different underlying genetic factors compared to conventional resistance genes. The resistance mechanism of RBgh2 involves temporary genome-wide gene expression changes and constitutive changes, especially at the RBgh2 locus, inducing defence-related genes associated with innate immunity and pathogen recognition.

Summary: The introduction of mlo-based resistance in wheat is a significant advancement in crop breeding for durable disease resistance. By screening mutant plants, we obtained triple homozygous mlo mutant lines that showed highly effective resistance against powdery mildew attacks. These mutations all contributed to resistance, but had varying effects on the occurrence of symptoms.

Summary: Terminal heat stress is a major obstacle for wheat production in South Asia. This study aimed to identify heat-tolerant wheat genotypes and determine an easy phenotyping trait for this purpose. A cross was made between two popular cultivars, one with heat tolerance and the other with high-yielding but susceptible to terminal heat stress. 167 recombinant inbred lines (RILs) were tested in different environments, and normalized difference vegetation index (NDVI_AH) and grain filling duration (GFD) were found to be significant traits for genotype, environment, and genotype x environment interaction. Correlation analysis showed that NDVI_AH had a significant association with grain yield (GY) in most environments. The study suggests that NDVI_AH and GFD are important traits for breeding wheat varieties with terminal heat stress tolerance.

Summary: Exserohilum leaf spot is a newly arising fungal disease that primarily affects monocots. It can cause symptoms on major cereals like wheat, rice, millets, and finger millet, with reddish-brown lesions observed in Poaceae plants. Histopathological studies reveal that conidia produce appressoria within 24 hours and penetrate the host through stomata or epidermal cells. Collateral hosts serve as an infection reservoir, allowing the pathogen to survive without its primary host, and major cereals like wheat and rice indicate its importance as an emerging plant pathogen.

Summary: The present study evaluated the effects of spot blotch and terminal heat stress on the morphological traits of spring wheat in the Eastern Indo-Gangetic Plains. High temperature and spot blotch significantly reduced the performance of traits in GC-2 conditions. The study highlighted the significance of AUSDC and AUNDC in determining the performance and yield-contributing traits of crops under stress conditions.
