The nematophagous fungus Hirsutella rhossiliensis Minter and Brady produces adhesive spores that ge rmina te direct ly through the cuticle of host nematodes (3). When juveni les o f the plant-parasi t ic nematode Criconemella xenoplax (Raski) Luc and Raski were inoculated with spores of this fungus and incubated in water, only a small pe rcen tage became infec ted (3). Nematodes that were heat ...

A cell-free system which catalyzes the biosynthesis of terpene hydrocarbons when supplemented with mevalonate, Mn(2+), and ATP was prepared from the scutellum-embryonic axis region of maize seedlings. The capacity of this system for the production of terpene hydrocarbons was enhanced 50- to 100-fold when the seedlings were exposed for 48 hours to the fungus Rhizopus stolonifer prior to tissue h...

• Transformed aubergine plants constitutively expressing the Dm-AMP1 antimicrobial defensin (from Dahlia merckii ) were generated and characterized. • Transgenic plants were selected on kanamycin and screened by polymerase chain reaction analysis. The expression of Dm-AMP1 in plant tissues and its release in root exudates were detected by Western blot analyses. Dm-AMP1 localization was performe...

Background: Emerging of microbial resistance, spread life-threatening diseases, and biological control pathogens destroying economically important crops, are serious problems that encourage scientists to search for unusual sources novel compounds with activities. Fungi promising such due their ability produce variety secondary metabolites could be, if truly investigated, the solution currently ...

medicinal plants are infected by fungal diseases. a four years survey indicated that, there are various fungal infections in roots and shoots of several medicinal plants that grown in isfahan. lavender (lavandula angustifolia), rosemarry (rosmarinus officinalis) and viper’s bugloss (borago officinalis) plants were infected by fusarium oxysporum and f. solani on roots, showing wilting and eventu...
