First Report of Fomitopsis meliae Causing Brown Wood Rot on Living Lemon Trees in Arizona and California.

Plant Dis 2021 Mar 5. Epub 2021 Mar 5.

University of Arizona, School of Plant Sciences, Yuma, Arizona, United States;

Arizona is one of the largest producers of premium lemons for fresh market in the world. In 2018, 54,000 metric tons of lemons were produced on more than 7,300 acres. In recent years, wood rot diseases have become increasingly important in desert citrus production, with an incidence rate of 70 to 100% in some lemon orchards in Yuma, and lower rates in lemon orchards in the California desert.

Alteration in the ultrastructural morphology of mycelial hyphae and the dynamics of transcriptional activity of lytic enzyme genes during basidiomycete morphogenesis.

J Microbiol 2017 Apr 26;55(4):280-288. Epub 2017 Jan 26.

Laboratory of Microbiology, Institute of Biochemistry and Physiology of Plants and Microorganisms, Russian Academy of Sciences IBPPM RAS, 13 Prospekt Entuziastov, Saratov, 410049, Russian Federation.

The morphogenesis of macromycetes is a complex multilevel process resulting in a set of molecular-genetic, physiological-biochemical, and morphological-ultrastructural changes in the cells. When the xylotrophic basidiomycetes Lentinus edodes, Grifola frondosa, and Ganoderma lucidum were grown on wood waste as the substrate, the ultrastructural morphology of the mycelial hyphal cell walls differed considerably between mycelium and morphostructures. As the macromycetes passed from vegetative to generative development, the expression of the tyr1, tyr2, chi1, chi2, exg1, exg2, and exg3 genes was activated. Read More

Morphological differences of symbiotic fungi Smittium culisetae (Harpellales: Legeriomycetaceae) in different Dipteran hosts.

Mycol Res 2009 Sep 12;113(Pt 9):967-72. Epub 2009 Jun 12.

Department of Biological Sciences, Life Sciences Building, Rm 124, University of South Alabama, Mobile, AL 36688-0002, USA.

Harpellales (Legeriomycetaceae, Zygomycota) or 'trichomycetes' are fungi that inhabit the digestive tracts of arthropods such as insects, millipedes, and crustaceans. In the current study we examined changes in 5 morphological characters of Smittium culisetae (Harpellales: Legeriomycetaceae) between the two dipteran (mosquito, black fly) hosts reared under 3 different temperatures (17, 22, 30 degrees C). Both host and temperature had a pervasive effect on the linear dimension of trichospores, their generative cells and hyphae width. Read More

Z Zizka J Gabriel

Folia Microbiol (Praha) 2006 ;51(2):109-13

Institute of Microbiology, Academy of Sciences of the Czech Republic, 142 20 Prague, Czechia.

Autofluorescence of fruiting bodies of the wood-rotting fungus Fomes fomentarius has been observed and is described among native macrofungi for the first time. The strongest yellow autofluorescence with blue excitation was displayed by pith sets, a weaker yellow, yellow-green to yellow-red fluorescence was due to generative thin-walled hyphae while the weakest yellow-reddish fluorescence was emitted by thick-walled skeletal hyphae (though their parts may emit a more intensive yellow fluorescence). This yellow, yellow-green to yellow-red autofluorescence was assessed to be more intensive than the emission described so far in bacteria and fungi (except for lysed hyphae of the fungus Trametes versicolor).

Haustorial Function During Development of Cleistothecia in Blumeria graminis f. sp. tritici.

Plant Dis 1998 May;82(5):507-511

Institute of Microbiology TU Braunschweig, Spielmannstr. 7, D-38106 Braunschweig, Germany.

Cleistothecia of Blumeria graminis are a means of survival under adverse conditions as well as a means of sexual reproduction, and are produced by the generative mycelium at the end of the vegetation period. Vital stains and C-labeled sucrose were transported from the host (Triticum aestivum) through the haustoria into the generative mycelium. Translocation was intense during the early developmental stage of the generative mycelium. Read More
