Alternaria radicina; unveiling the cause, spread, and molecular basis of a novel coriander leaf blight disease in Egypt.

ABSTRACT: Coriandrum sativum L. faced a new and previously undocumented leaf blight disease for the first time. This disease manifests initially as small, circular, or irregular brown spots on older leaves, which gradually expand and merge into dark brownish blotches over time. This disease's impact is detrimental to plant health and seed quality. Through comprehensive morphological characteristics, and molecular identification (GenBank OL823169), the pathogen was conclusively identified as Alternaria radicina. Further confirmation was obtained by analyzing target sequences for the Alt-a-1 gene (GenBank OR492259). Koch's postulates were strictly adhered to, leading to the successful re-isolation of A. radicina from artificially infected 8-week-old coriander plants (local
