Aseptic Culture Systems of Radopholus similis for In Vitro Assays on Musa spp. and Arabidopsis thaliana.
Radopholus similis is one of the most damaging nematodes in bananas. Chemical control is currently the most-used method, but nematode control through genetic improvement is widely encouraged. The objective of this study was to establish an aseptic culture system for R. similis and determine whether R. similis can infect and reproduce on in vitro banana plantlets and in vitro Arabidopsis thalian...
متن کاملAggressiveness and Damage Potential of Central American and Caribbean Populations of Radopholus spp. in Banana.
Monoxenic cultures of burrowing nematode populations extracted from banana roots from Belize, Guatemala, Honduras, and Costa Rica were established on carrot discs. Cultures of Radopholus spp. were also obtained from Florida, Puerto Rico, Dominican Republic, and Ivory Coast. The aggressiveness (defined as reproductive fitness and root necrosis) of these populations was evaluated by inoculating b...
متن کاملEndophytic Fusarium spp. from Roots of Lawn Grass (Axonopus compressus).
Fungal endophytes are found inside host plants but do not produce any noticeable disease symptoms in their host. In the present study, endophytic Fusarium species were isolated from roots of lawn grass (Axonopus compressus). A total of 51 isolates were recovered from 100 root segments. Two Fusarium species, F. oxysporum (53%) and F. solani (47%), were identified based on macroconidia and conidi...
متن کاملMonoxenic Culture of Banana-Parasitic Nematodes on Musa acuminata cv. Poyo shoots.
Among nematodes parasitizing bananas throughout the world, Radopholus similis and Helicotylenchus multicinctus are the most widespread and damaging species. Besides these two nematodes, Hoplolaimus pararobustus is encountered frequently in Ivory Coast and has been increasing in banana growing areas for the past 25 years (6,10). In vitro culture systems could facilitate screening for resistance ...

During the growing seasons of 2009 and 2010, same tomato fields throughout Marvdasht were visited and 96 isolates of Fusarium spp. were collected from root, crown and stem of diseased tomato plants. Isolates were identified as based on morphological characteristics. They were divided into four species namely: Fusarium solani, F. pseudoanthophilum, F. oxysporum and F. equiseti. These species,...
