Genetic diversity and pathogenicity differentiation of Sclerotinia sclerotiorum on rapeseed (Brassica napus L.) in Anhui Province, China

D. F. Xu, Li, X. L., Pan, Y. M., Dai, Y. L., Li, P., Chen, F. X., Zhang, H. J., Guo, M., and Gao, Z. M., Genetic diversity and pathogenicity differentiation of Sclerotinia sclerotiorum on rapeseed (Brassica napus L.) in Anhui Province, China, vol. 13, pp. 10704-10713, 2014.

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 pathogenicity type, and strong pathogenicity type. This suggested that there was differentiation in the pathogenicity among the strains tested of S. sclerotiorum.

Molecular characterization of the pathogenic plant fungus Rhizoctonia solani (Ceratobasidiaceae) isolated from Egypt based on protein and PCR-RAPD profiles

M. A. Mahmoud, Al-Sohaibani, S. A., Abdelbacki, A. M. M., Al-Othman, M. R., Aziz, A. R. M. Abd El-, Kasem, K. K., Mikhail, M. S., Sabet, K. K., Omar, M. R., and Hussein, E. M., Molecular characterization of the pathogenic plant fungus Rhizoctonia solani (Ceratobasidiaceae) isolated from Egypt based on protein and PCR-RAPD profiles, vol. 11, pp. 3585-3600, 2012.

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 proteins of the fungal isolates were electrophoresed using SDS-PAGE and gel electrophoreses.

Characterization of Chinese eggplant isolates of the fungal pathogen Verticillium dahliae from different geographic origins

Z. Xu, Ali, Z., Hou, X., Li, H., Yi, J. X., and Abbasi, P. A., Characterization of Chinese eggplant isolates of the fungal pathogen Verticillium dahliae from different geographic origins, vol. 12, pp. 183-195, 2013.

Verticillium dahliae is a fungal pathogen that causes wilt disease in a wide range of host plants. Characterization of virulence, morphological, and molecular variations among V. dahliae isolates from different geographic origins is essential for any breeding program aimed at producing plant cultivars resistant to this disease. We characterized virulence variation among V.

Virulence insights from the Paracoccidioides brasiliensis transcriptome

A. Henrique Tavares, Silva, S. Souza, Bernardes, V. Vilmar, Maranhão, A. Queiróz, Maranhão, A. Queiróz, Kyaw, C. Maria Kyaw, Poças-Fonseca, M., and Silva-Pereira, I., Virulence insights from the Paracoccidioides brasiliensis transcriptome, vol. 4. pp. 372-389, 2005.

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, little is known about its virulence genes. In this sense, we performed a search for putative virulence genes in the P. brasiliensis transcriptome.

Chromobacterium violaceum genome: molecular mechanisms associated with pathogenicity

C. F. Alves de Brito, Carvalho, C. M. B., Santos, F. R., Gazzinelli, R. T., Oliveira, S. C., Azevedo, V., and Teixeira, S. M. R., Chromobacterium violaceum genome: molecular mechanisms associated with pathogenicity, vol. 3, pp. 148-161, 2004.

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 immunodeficient individuals. Although rare, infections with C. violaceum are characterized by rapid dissemination and high mortality. With the complete genome sequence of C.
