In the “1KFG: Deep Sequencing of Ecologically-relevant Dikarya” project (CSP1974), we aim to sequence additional sampling of genomic diversity within keystone lineages of plant-interacting fungi and saprophytic fungi that are of special ecological importance for understanding terrestrial ecosystems.

Fusarium redolens is a soil-borne plant pathogen in temperate prairies. It causes diseases such as root, crown, and spear rot, seedling damping-off, and wilting disease. It is known to produce the alkaloids peimisine and imperialine-3β-D-glucoside, which have been used in traditional Chinese medicine. This species’ morphology is visually indistinguishable from that of Fusaruim oxysporum. Intermediates also exist between the two species. These species cause similar, at times identical, symptoms in plant hosts and can occur together in infections. Differentiating between the two species is important for the efficient management of their associated diseases through species-specific diagnostics and development of resistant germplasms in hosts. Restriction fragment length polymorphism (RFLP) analysis of the ribosomal DNA (rDNA) internal transcribed spacer (ITS) region is used to differentiate the two.
