Colletotrichum fioriniae Marcelino & Gouli (2008)
|
Colletotrichum fioriniae is a fungal plant pathogen and endophyte of fruits and foliage of many broadleaved plants worldwide.[1][2] It causes diseases on agriculturally important crops, including anthracnose of strawberry, ripe rot of grapes, bitter rot of apple, anthracnose of peach, and anthracnose of blueberry.[3] Its ecological role in the natural environment is less well understood, other than it is a common leaf endophyte of many temperate trees and shrubs[2] and in some cases may function as an entomopathogen.[4]
Taxonomic history
C. fioriniae was formally described as a variety of Colletotrichum acutatum in 2008,[4] and as its own species shortly thereafter.[5] However, while it had not previously been recognized as a separate species, when grown on potato dextrose agar it produces a distinct pink to maroon red color on the bottom side and was described in historical studies as "chromogenic" isolates of Glomerella cingulata.[6][7][8] It is currently recognized as a species within the C. acutatum species complex.[1]
Identification
C. fioriniae produces conidia that are smooth-walled, hyaline (glassy and translucent), with acute (pointed) ends, measuring about 15 x 4.5 microns.
Reproduction
Like other species in the C. acutatum species complex, C. fioriniae reproduces almost exclusively via the production of asexual spores called conidia.[10][1] These conidia are often produced in sticky gelatinous orange masses that are rain-splash dispersed.[10][11] Conidia are mostly produced at temperatures from 10 to 30 °C, such that in temperate deciduous forests and orchards rain-splash dispersal occurs from bud-break to leaf drop.[12]
Pathogenic lifestyle
As a plant pathogen, C. fioriniae has a hemibiotrophic lifestyle, where infections are initially biotrophic (or latent or quiescent, depending on the point of view) before switching to necrotrophy and active killing of the plant cells.[10]
