Role of a Fusarium culmorum ABC transporter (FcABC1) during infection of wheat and barley

Autophagy provides nutrients for nonassimilating fungal structures and is necessary for plant colonization but not for infection in the necrotrophic plant pathogen Fusarium graminearum

“…The plants were watered every second day with a nutrient solution. 42 In barley, inoculations were conducted on spikes 7-8 d after their emergence from the flag sheath. A macroconidial suspension (4 ¾ 10 4 conidia/ml) of either WT or the DFgatg8 strain was applied by spray inoculation to the entire spike.…”

Genomic analysis of host–pathogen interaction between Fusarium graminearum and wheat during early stages of disease development

“…ABC transporters are membraneassociated proteins involved in transport of small molecules across membranes against a concentration gradient, coupled to the hydrolysis of ATP. Some fungal ABC transporters have been associated with plant pathogenicity (Fleissner et al, 2002;Stergiopoulos et al, 2003;Urban et al, 1999), including a gene in the closely related species F. culmorum (Skov et al, 2004); ABC transporters also have been shown to confer resistance to plant phytoalexins (Schoonbeek et al, 2001). However, deletion of FG08308.1 in this study resulted in no loss of pathogenicity to wheat under the conditions tested.…”

MgAtr7, a new type of ABC transporter from Mycosphaerella graminicola involved in iron homeostasis

“…This contrasts to the situation in Aspergillus nidulans where a similar functional search resulted in the identiWcation of the azole transporter AtrG (Andrade, 2000). A similar approach to identify ABC transporters involved in pathogenicity has recently led to the isolation of the ABC transporter gene FcABC1 from Fusarium culmorum (Skov et al, 2004). Our functional homology search in M. graminicola was less successful, indicating that orthologs do not necessarily perform similar functions.…”
