Alternaria leaf spot and black rot in Brassica rapa L.: resistance mechanisms, breeding solutions and prospects
https://doi.org/10.30901/2227-8834-2026-1-o13
Abstract
The review presents an analysis of recent studies on the resistance of Brassica rapa L. crops to the most dangerous pathogens – fungi of the genus Alternaria, and the bacteria Xanthomonas campestris pv. campestris. Geographic distribution, virulence, and racial composition of pathogen populations were analyzed, and regional features of their distribution were identified. Particular attention was paid to the research into the biochemical mechanisms of plant resistance, including the role of secondary metabolites (glucosinolates, phenolic compounds, and phytoalexins), and the activity of the key defense enzymes. Modern approaches to breeding for resistance were considered, including the use of representatives of relative genera, and marker-assisted selection. It is shown that the integration of traditional and molecular genetics methods is a promising trend for the development of cultivars with complex resistance, adapted to modern phytopathological challenges in the context of global climate change.
Supporting agencies: The review was prepared within the framework of the state task according to the theme plan of VIR, Project No. FGEM-2022-0003 “Global genetic resources of vegetable and cucurbit crops in the VIR collection: effective ways to disclose ecogenetic patterns in the formation of their diversity and utilization of breeding potential”.
