Chromobacterium violaceum; Genome; Pathogenicity; Virulence

Chromobacterium violaceum is a versatile, Gram-negative β-protebacterium that grows in a variety of ecosystems in tropical and subtropical areas, such as the water and borders of the Negro River, in the Amazon region of Brazil. Although it is a saprophyte and is generally considered non-pathogenic, sporadic cases of human infection have been described, mainly in young children and in ... more

Dimorphism; Host-pathogen interaction; Paracoccidioides brasiliensis; Pathogenicity; Transcriptome analysis; Virulence

Paracoccidioides brasiliensis, the etiologic agent of paracoccidioidomycosis, is a dimorphic fungus, which is found as mycelia at 22-26ºC and as yeasts at 37ºC. A remarkable feature common to several pathogenic fungi is their ability to differentiate from mycelium to yeast morphologies, or vice-versa. Although P. brasiliensis is a recognized pathogen for humans, ... more

Anastomosis groups; Cotton; Pathogenicity; RAPD-PCR; Rhizoctonia solani; SDS-PAGE

Twenty-one isolates of Rhizoctonia solani were categorized into three anastomosis groups consisting of AG-4-HG-I (eight isolates), AG-2-2 (nine isolates) and AG-5 (four isolates). Their pathogenic capacities were tested on cotton cultivar Giza 86. Pre-emergence damping-off varied in response to the different isolates; however, the differences were not significant. Soluble ... more

Genetic diversity; Inter-simple sequence repeat (ISSR); Oilseed rape; Pathogenicity; Sclerotinia sclerotiorum

The pathogenicity of 47 isolates of Sclerotinia sclerotiorum from oilseed rape (Brassica napus L.) in Anhui, China, was tested by detached leaf inoculation using the susceptible rape cultivar Wanyou-14. All isolates were pathogenic to the cultivar and could be grouped into 3 categories based on the lesion length on the leaves tested: weak pathogenicity type, intermediate ... more

Morphological characters; Pathogenicity; TEF-1α; Unweighted pair group method with arithmetic mean

The occurrence of Fusarium spp associated with pecan tree (Carya illinoinensis) diseases in Brazil has been observed in recent laboratory analyses in Rio Grande do Sul State. Thus, in this study, we i) obtained Fusarium isolates from plants with disease symptoms; ii) tested the pathogenicity of these Fusarium isolates to pecan; iii) characterized and ... more

Molecular difference; Morphotype; rDNA ITS sequence; Rotifer

Morphological variation in rotifers is affected by environmental conditions, making it hard to identify some rotifer taxa. We examined the rDNA ITS sequences of 10 unspined (KCU1-KCU10) and 17 spined (KCS1-KCS17) Keratell cochlearis clones, 26 two-spined (KQT1-KQT26), 18 single-spined (KQS1-KQS18) and 9 unspined (KQU1-KQU9) K. quadrata clones, and 17 long-spined (BL1- ... more

Phytophthora capsici is a plant pathogenic oomycete that damages numerous crops worldwide. Consequently, interest in research on the genetic structure of this species has grown in recent decades. However, there is little information about P. capsici in eastern China. We investigated the genetic diversity of P. capsici isolates from three large regions of Anhui ... more

Curcuma alismatifolia; Genetic relationship; ISSR-PCR; Molecular identification

The genus Curcuma is a member of the ginger family (Zingiberaceae) that has recently become popular for use as flowering pot plants, both indoors and as patio and landscape plants. We used PCR-based molecular markers (ISSRs) to assess genetic variation and relationships between five varieties of curcuma (Curcuma alismatifolia) cultivated in Malaysia. Sixteen ISSR primers ... more

Genetic relationship; ISSR-PCR; Labisia pumila species

The genus Labisia (Myrsinaceae) is a popular medicinal plant in Malaysia. We examined the genetic relationship among three varieties of L. pumila var. pumila, L. pumila var. alata, L. pumila var. lanceolata and Labisia paucifolia using an ISSR assay. Fifty-eight primers were tested, among which 18 gave reliable ... more
