This is a family of virulence proteins that are found in pathogenic Streptomyces species.

1: nec1, a gene conferring a necrogenic phenotype, is conserved in plant-pathogenic Streptomyces spp. and linked to a transposase pseudogene. Bukhalid RA, Chung SY, Loria R; Mol Plant Microbe Interact. 1998;11:960-967. PMID:9768513

2: Horizontal transfer of the plant virulence gene, nec1, and flanking sequences among genetically distinct Streptomyces strains in the Diastatochromogenes cluster. Bukhalid RA, Takeuchi T, Labeda D, Loria R; Appl Environ Microbiol. 2002;68:738-744. PMID:11823214
