Fusarium redolens

Fusarium hostae has been found as a sister taxon to F. redolens, and they form a strongly supported clade (100% bootstrap).

[6] The mycelium of F. redolens is composed of hyphae that have been noted to appear fibrous, powdery, or like “cotton wool.”[7] Mycelia can be white, cream, or pink.

[2][8][9] The central region appears pink and gradually lightens towards the edge where the marginal hyphae are white.

[1][4] 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.

[1][6] Restriction fragment length polymorphism (RFLP) analysis of the ribosomal DNA (rDNA) internal transcribed spacer (ITS) region is used to differentiate the two.

[7] It has a worldwide range and has been isolated in Algeria, Canada, China, Germany, Greece, Italy, Kazakhstan, Lebanon, Morocco, the Netherlands, New Zealand, Pakistan, Poland, South Africa, Spain, Turkey, the United States, and the United Kingdom.

[5] Recorded plant hosts are Aleppo pine, American ginseng, asparagus, barley, carnation, chickpea, flax, lentil, onion, pea, pelargonium, potato, rose, soybean, spinach, tomato, wheat, and wild rocket.

[1][2][3][7][8][9][10] Depending on the host, F. redolens causes root, crown, and/or spear rot, seedling damping-off, and wilt diseases.

[1][3][4] Symptoms of infection include brown to black necrotic lesions on roots, foliar yellowing, wilting, reduction of emergence, stunting, and rotting of seeds and seedlings.

[3][4] While F. redolens causes similar symptoms in plants as Fusarium oxysporum, it is important to differentiate between these species when assessing an infection for contributions towards developing resistant germplasms in target crops.

Both of these compounds are major alkaloids that are found in bulbus Fritillariae cirrhosae (BFC), which is an herb sourced from FUW.

BFC has been used in traditional Chinese medicine for over 2000 years to treat respiratory diseases and has a $400 million USD industry surrounding it.
