Plant defense response against Fusarium oxysporum and strategies to develop tolerant genotypes in banana

“…These findings were proved against hemibiotrophic pathogen F. graminearum. when there is no evidence of necrotrophy during early stages of infection (Brown et al 2010;Goswami and Kistler 2004), activation of SA signaling curtails F. graminearum infection and, during the later stages of interaction, JA-regulated defenses target the necrotrophic phase of the fungal life cycle.…”

Antibacterial to antifungal conversion of neamine aminoglycosides through alkyl modification. Strategy for reviving old drugs into agrofungicides

“…11 An example of the limitations of current agrofungicide use is illustrated by Fusarium head blight (FHB)-a destructive and costly disease of wheat, barley and other small grains caused by F. graminearum. 12 There is a serious and persistent need for new agrofungicides that are efficacious, less toxic, cost effective and that do not promote resistance. Although potentially useful as agrofungicides, 1 the application of currently available aminoglycosides to combat crop diseases is discouraged as such practices are predicted to promote bacterial resistance to therapeutically used antibiotics.…”

Multilocus sequence analysis of Fusarium pseudograminearum reveals a single phylogenetic species

“…In the USA the disease occurs in the states of Idaho, Oregon, Washington, Colorado, Wyoming and Texas where it is variously named as crown rot, dryland foot rot, foot rot, dryland root rot and root rot; all have a complex aetiology with F. pseudograminearum, F. culmorum and F. avenaceum as the dominant pathogens (Paulitz et al 2002). Additionally, F. pseudograminearum has been responsible for major epidemics in Australia (Burgess et al 1987) of Fusarium head blight (FHB;McMullen et al 1997), a disease that is emerging as a sporadic, but significant, threat to global wheat production (Goswami & Kistler 2004). Field isolates of F. pseudograminearum from both wheat spikes and crowns have been shown to cause FHB in greenhouse tests (Akinsanmi et al 2004;Monds et al 2005).…”
