Resource Announcement of 18 <i>Clavibacter nebraskensis</i> Genomes Isolated from Maize in Mexico

Gram-positive Clavibacter nebraskensis is the causal agent of Goss's wilt and leaf blight of maize. The disease is documented across corn-producing regions of the United States and two Canadian provinces. In 2024, C. nebraskensis was confirmed in Mexico for the first time, posing a challenge to maize biosecurity given its status as a quarantine organism under NOM-018-FITO-1995. This finding demonstrates the necessity of establishing C. nebraskensis surveillance programs for maize in Mexico. To support this effort, 18 C. nebraskensis isolates from two states in Mexico were sequenced. Comparative genomic analysis showed that all isolates clustered with the C. nebraskensis type strain NCPPB 2581ᵀ. These genomic resources are essential for advancing research on C. nebraskensis epidemiology, biology, and evolution across North America. [Formula: see text] Copyright © 2025 The Author(s).
