The trichothecene mycotoxin deoxynivalenol facilitates cell‐to‐cell invasion during wheat‐tissue colonization by Fusarium graminearum

open access: yesMolecular Plant Pathology, Volume 25, Issue 6, June 2024.
The trichothecene mycotoxin deoxynivalenol (DON) dampens host immune responses and facilitates cell‐to‐cell invasion through plasmodesmatal pit fields in wheat floral tissues. Abstract Fusarium head blight disease on small‐grain cereals is primarily caused by the ascomycete fungal pathogen Fusarium graminearum.

Production of fusarium-mycotoxins by dispersal ascospores of Gibberella zeae.

open access: yesJapanese Journal of Phytopathology, 1990
ムギ作圃場における空中飛散G. zeaeの子のう胞子およびイネ刈株残渣の子のう殻から分離したG. zeaeを精白米培地で培養してマイコトキシン生産性を調べた。飛散子のう胞子32菌株すべてがゼアラレノンを生産し,20菌株(62.5%)はトリコテセン系マイコトキシンを生産した。後者のうち15菌株はニバレノールとフザレノン-X生産菌,4菌株はデオキシニバレノールと3-アセチルデオキシニバレノール生産菌,1菌株はT-2トキシンとネオソラニオール生産菌であった。また,イネの刈株残査から分離した14菌株のうち,トリコテセン生産性を示した13菌株はすべてニバレノール生産菌であり,他の生産菌は認められなかった。このように ...

Identification of the down-regulated genes in a mat1-2-deleted strain of Gibberella zeae, using cDNA subtraction and microarray analysis

open access: yes, 2006
Gibberella zeae (anamorph: Fusarium graminearum), a self-fertile ascomycete, is an important pathogen of cereal crops. Here, we have focused on the genes specifically controlled by the mating type (MAT) locus, a master regulator of sexual developmental ...

Differential effect of environmental conditions on the growth and regulation of the fumonisin biosynthetic gene FUM1 in the maize pathogens and fumonisin producers Fusarium verticillioides and Fusarium proliferatum

open access: yes, 2010
The effects of ecophysiological factors, temperature and solute potential, on both the growth and the regulation of the fumonisin biosynthetic FUM1 gene were studied and compared in one isolate each of the two closely related fumonisin-producing and ...
