Summary: One hundred accessions of Diplotaxis tenuifolia and Eruca spp. were screened for resistance to downy mildew. Cultivated rocket accessions showed a resistant response, while wild rocket accessions exhibited higher susceptibility in cotyledons. There was a significant correlation between disease index in cotyledons and leaves. Molecular markers analysis revealed genetic distance between Diplotaxis and Eruca, along with diverse interactions with the pathogen. Future studies will focus on evaluating different responses under greenhouse or field production and genome mapping of downy mildew resistance-related genetic features.

Summary: Pseudoperonospora humuli is a destructive oomycete causing downy mildew in cultivated hops. The pathogen overwinters in plants, leading to significant crop loss, and is managed by sanitation practices, resistant cultivars, and fungicides. Future disease management may involve genomics and effector discovery.

Summary: This review summarizes the efforts made in the past 50 plus years to identify resistant sources against powdery mildew and downy mildew in melon germplasm. A total of 239 melon accessions resistant to powdery mildew and 452 accessions resistant to downy mildew have been identified. Among these resistant sources, C. melo var. cantalupensis accessions PMR 45, PMR 5, PMR 6, and WMR 29, as well as C. melo var. momordica accessions PI 124111, PI 124112, and PI 414723, are considered as the most valuable germplasm. Genetic mapping has identified several dominant genes, recessive genes, and QTLs conferring resistance to both powdery mildew and downy mildew.

Summary: The study demonstrated that using rare sugar-based products can induce resistance in grapevine leaves against downy mildew, primarily through enhancing the activation of salicylic acid- and jasmonic acid/ethylene-responsive genes and stilbene phytoalexin accumulation. IFP48 provides protection against P. viticola infection, but shows inconsistent effects against B. cinerea.

Summary: A subset representing the genetic diversity of a base collection is crucial for efficient plant genetic resources utilization, especially for vegetatively propagated tuber crops like white Guinea yam. In this study, a mini-core collection of 102 Dioscorea rotundata accessions was developed, retaining nearly 98% of the SSR allelic diversity of the base collection. The selected mini-core accessions exhibited a wide range of variation in agronomic traits and could be useful for breeding programs and genetic improvement in West Africa.

Summary: The study screened 165 quinoa accessions for resistance to downy mildew caused by Peronospora variabilis, revealing some accessions with moderate and high resistance. It also demonstrated the positive correlation of AUDPC with defoliation rate and the negative correlation with plant height, highlighting the importance of disease resistance screening by comparing disease-related agronomic characteristics.

Summary: This study investigates the role of the PvCRN11 protein in resistance against downy mildew in grapes. The results show that PvCRN11 induces plant immune response and inhibits the colonization of downy mildew pathogens. This research provides potential application of PvCRN11 as a protectant against downy mildew in grape production.

Summary: Grain mold disease poses a significant threat to the production of sorghum, impacting its quality and safety as human food and livestock feed. Efforts to improve sorghum resistance to this disease complex are crucial for ensuring agricultural productivity, profitability, and public health. Recent advances in understanding the genetic and biochemical interactions among fungal pathogens, mycotoxins, and sorghum hosts are essential for delivering improved germplasm with robust disease resistance.

Summary: The transcriptome profiles of developing grain in resistant and susceptible sorghum genotypes revealed differential regulation of molecular and cellular processes related to defense, secondary metabolism, and flavonoid biosynthesis. Resistance was associated with increased expression of genes encoding regulatory factors, antimicrobial peptides, and storage proteins, suggesting potential targets for crop improvement.

Summary: Little millet, native to India, is a highly nutritious grain that can grow well in marginal lands and withstand drought and waterlogging conditions. Research shows significant variability in agronomic and grain nutrient traits of little millet landraces, with some accessions displaying promising characteristics. Further evaluation of these accessions under different conditions could lead to the identification of valuable varieties for cultivation or improvement of little millet.

Summary: This study evaluated the sorghum mini core collection and performed association mapping, identifying QTLs associated with flowering time, biomass, plant height, and other traits. Transgenic studies revealed a gene that, when overexpressed, increased biomass and sugar yield in sorghum and delayed flowering. These findings have important implications for genetic enhancement of plants.
