Data from: Genomic features of the host-specific fungal biocontrol agent Ramularia crupinae approved for the management of the federally noxious weed Crupina vulgaris

Published by Agricultural Research Service | Department of Agriculture | Metadata Last Checked: January 27, 2026 | Last Modified: 2025-11-21
Ramularia crupinae is a foliar and stem blighting fungal pathogen specific to the invasive rangeland weed common crupina (Crupina vulgaris). This fungal plant pathogen was recently approved by the Animal and Plant Health Inspection Service (APHIS) as the first biological control agent for the management of common crupina in the western United States. The genome assembly for R. crupinae 00-010 (https://mycocosm.jgi.doe.gov/Ramcr1/Ramcr1.info.html) contains 18 contigs totaling 37.9 Mb, and was annotated using the JGI fungal annotation pipeline. The information contained within this Ag Data Commons dataset provides an updated R. crupinae chromosome-level genome assembly. These data are freely available for research purposes. Resources in this dataset: Resource Title: Ramularia crupinae chromosome-level assembly File Name: Ramularia crupinae_14chrm.zip Resource Description: The R. crupinae genome was re-assembled to improve the contiguity of putative chromosome length scaffolds and attempt chromosome-level assembly. This improved assembly was 37,889,040 bp in size with 15 fragments (N50: 2,786,127 bp) and 810x coverage.
