Reactions of some cucumber (Cucumis sativus L.) lines and hybrids to zucchini yellow mosaic virus (ZYMV) and selection of tolerant breeding lines

International Journal of Horticultural Science, 1999
In the past years zucchini yellow mosaic virus (ZYMV) has been appeared as a new pathogen of cucurbitaceous plants in Hungary. It caused severe disease outbreaks on the fields of pickling cucumber hybrids which are highly tolerant to cucumber mosaic ...

Allelic Variation in Maize Malate Dehydrogenase 7 Shapes Promoter Methylation and Banded Leaf and Sheath Blight Resistance

Advanced Science, EarlyView.
In this study maize chloroplastic malate dehydrogenase7 (ZmMDH7), is identified as a Rhizoctonia solani resistance gene in maize. ZmMDH7 is regulated by transcription factor ZmWRKY44 via pathogens challenge to elevate mitochondrial ROS and SA signaling pathway.

Distribution of Virus Symptoms and Viruses Infecting Field-Grown Cucurbit Crops Under Natural Tropical Conditions Within a Humid Rainforest Transition Agro-Ecology in Nigeria

Annals of Tropical Research, 2016
Farmers’ fields where cucurbit crops were grown in seven Local Government Areas (LGA) of Ogun state were surveyed in 2009 and 2010 for incidence and severity of virus symptoms and the identity of the viruses infecting the crops were determined using DAS-

Evaluating the potential of RNA interference for control of striped cucumber beetle, Acalymma vittatum (Fabricius) (Coleoptera: Chrysomelidae)

Pest Management Science, EarlyView.
SCB has a robust RNAi response to injected dsRNA, but oral RNAi is less efficient. Nucleases do not appear to be responsible for the discrepancy, suggesting other factors are involved. Abstract BACKGROUND The striped cucumber beetle (SCB) is a serious pest of cucurbit crops, causing damage both by feeding on plants and by vectoring plant diseases ...

Identification of positive and negative regulators of antiviral RNA interference in Arabidopsis thaliana

Nature Communications, 2022
Whether natural variations of plant virus resistance are enriched in genes of RNA interference pathway is unknown. Here, via genome-wide association studies, the authors identify regulators of the RDR6 and DCL2 antiviral pathways are involved in ...
