Genetic analysis of anthracnose resistance in ‘Pitanga’ dry bean cultivar
The results from allelism tests in fourteen F2 populations fit a 15 resistant : 1 susceptible ratio, which indicates that the resistance present in the ‘Pitanga’ cultivar is dominant and independent from genes and alleles already characterized. Expand
A comparison of dung beetle assemblage structure (Coleoptera: Scarabaeidae: Scarabaeinae) between an Atlantic forest fragment and adjacent abandoned pasture in Paraná, Brazil
A larger number of individuals was observed from December 1999 through March 2000, which is the time of the year when adults of Scarabaeinae normally emerge and fly, in the studied region. Expand
Pyricularia blast on white oats: a new threat to wheat cultivation
Results of disease severity analysis indicated that four white oat cultivars were resistant, seven were moderately resistant and the remaining were susceptible or highly susceptible to the new P. grisea isolates from black oats. Expand
Mechanism of resistance and presence of different resistance genes to Ramularia areola in two cotton genotypes
The results indicated that the resistance to R. areola in genotype CNPA BA 2003-2059 is governed by one dominant gene and that the Resistance in each one of the resistant genotypes is governedBy a different dominant gene. Expand
Characterization of race 65 of Colletotrichum lindemuthianum by sequencing ITS regions
The phylogenetic tree obtained based on the sequences of the ITS1 and ITS2 regions revealed the formation of two groups, one with a subgroup and high molecular variability among isolates of race 65 of C. lindemuthianum. Expand
Search for a Microsatellite Marker Linked with Resistance Gene to Xanthomonas axonopodis pv. malvacearum in Brazilian Cotton
It is believed that the microsatellite marker was linked with the resistance locus and hence may offer new perspectives for marker assisted selection against the angular leaf spot disease of cotton. Expand
INTRODUCTION Anthracnose is one of the most widespread and economically important common bean diseases (Pastor-Corrales, 2005). This disease, caused by the fungus Colletotrichum lindemuthianum, isExpand
Identification of genetic variability among isolates of Fusarium oxysporum f. sp. vasinfectum of cotton
The results of RAPD, PCR-RFLP of rDNA, ERIC and REP-PCR were comparable with each other and indicated the existence of genetic variability among some of the FOV isolates of different geographic origins, indicating the necessity of using different FOV isolate that represent the genetic diversity of the population.

Use of oval conidia as a tool to assess the genetic transfer among Colletotrichum sublineolum mutants
The production of oval conidia production in mutants for the reductase nitrate gene in C. sublineolum represents a promising alternative for the studies that require conidial use, such as genetic and pathogenicity studies, especially for the strains with a few or no spores in agar media. Expand
