Viruslike particles in tentoxin-producing strains of Alternaria alternata.
Double-stranded (ds) RNAs associated with viruslike particles have been found in six isolates of Alternaria alternata which produce tentoxin. Isolates had from one to three dsRNAs ranging in size from 1.0 to 5.1 kilobase pairs. In two isolates the dsRNAs were associated with 30-nm particles. No dsRNA was detected in any of six other tentoxin-producing isolates or nine isolates which did not pro...
متن کاملPlant extracts to control Alternaria alternata in Murcott tangor fruits.
BACKGROUND Alternaria alternata causes the Alternaria brown spot disease (ABS) in many tangerines and their hybrids worldwide. Plant extracts offer an alternative method for controlling this disease, which control is based on chemical fungicides. AIMS To identify plant species with antifungal properties against A. alternata, the causal agent of the ABS. METHODS Plant extracts prepared from ...
متن کاملPotential use of Iranian rhizobial strains as plant growth-promoting rhizobacteria (PGPR) and effects of selected strains on growth characteristics of wheat, corn and alfalfa
Abstract Many agricultural researches have been performed to improve soil productivity. Nitrogen (N) and Phosphorus (P) are essential elements which are utilized by the plants in large amounts. Phosphorus can be provided by applying chemical fertilizers. Microorganisms convert insoluble phosphate to the soluble form and some bacteria such as rhizobacteria play an important role in this proces...
