Variability of Colletotrichum spp in common bean.
The Colletotrichum genus presents large genetic variability, as demonstrated by the occurrence of several pathogenic races and phenotypic traits. The objective of this study was to characterize 22 strains of C. lindemuthianum and Colletotrichum spp recovered from anthracnose lesions and bean scab, and to verify the relationship between species of the Colletotrichum genus, which inhabit anthracn...
متن کاملEucalyptus growth promotion by endophytic Bacillus spp.
Clonal eucalyptus plantings have increased in recent years; however, some clones with high production characteristics have vegetative propagation problems because of weak root and aerial development. Endophytic microorganisms live inside healthy plants without causing any damage to their hosts and can be beneficial, acting as plant growth promoters. We isolated endophytic bacteria from euc...
متن کاملEndophytic fungal mutualists: seed-borne Stagonospora spp. enhance reed biomass production in axenic microcosms.
Fungal endophytes mainly belong to the phylum Ascomycota and colonize plants without producing symptoms. We report on the isolation of seed-borne fungal endophytes from Phragmites australis (common reed) that were ascribed to the genus Stagonospora. Nested polymerase chain reaction (PCR) assays revealed that a Stagonospora sp. regularly colonized reed as shown for a period of three years. In sp...
متن کاملInteractions Between Pea Seed - borne
approved: Richard 0. Hampton Pea seed-borne mosaic potyvirus pathotype 1 (PSbMV-P1) has the ability to infect most genotypes of Pisum sativum. The exception are those genotypes that are homozygous recessive for the sbm-1 gene. The life cycle of PSbMV pathotype 4 (PSbMV-P4) is unaffected by the sbm-1/sbm-1 genotype. Infectious clones of Pl-P4 recombinants were used to define the genomic segment ...
متن کامل[Fungal keratitis caused by Colletotrichum spp. A presentation of case].
CASE REPORT A 23 years old male with an unremarkable past medical history suffered an injury with a branch of a lemon tree in the right eye two days prior to presentation. The slit-lamp examination showed a central corneal erosion with a white tree-shaped stromal infiltrate and Tyndall +/++ in anterior chamber. Cultivation of corneal scraping was positive for Colletotrichum spp. The patient res...
