Phytophthora capsici

Biological characteristics and mating type distribution of Phytophthora capsici from China

Y. Du, Gong, Z. - H., Liu, G. - Z., Chai, G. - X., and Li, C., Biological characteristics and mating type distribution of Phytophthora capsici from China, vol. 13, pp. 396-405, 2014.

Phytophthora capsici from seven provinces of China were investigated for their mating type, hyphal growth, zoospore production, and virulence. All of the morphological characteristics and the results of polymerase chain reaction confirmed that these isolates were indeed Phytophthora capsici. The test of mating type showed that the mating types of 19 representative isolates from China varied.

Genetic diversity of Phytophthora capsici (Pythiaceae) isolates in Anhui Province of China based on ISSR-PCR markers

P. Li, Cao, S., Dai, Y. L., Li, X. L., Xu, D. F., Guo, M., Pan, Y. M., and Gao, Z. M., Genetic diversity of Phytophthora capsici (Pythiaceae) isolates in Anhui Province of China based on ISSR-PCR markers, vol. 11, pp. 4285-4296, 2012.

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 Province in eastern China based on ISSR-PCR technology. Thirteen random primers were screened and used to amplify DNA from 51 samples.

Molecular characterization and functional analysis of the Nep1-like protein-encoding gene from Phytophthora capsici

B. Z. Feng and Li, P. Q., Molecular characterization and functional analysis of the Nep1-like protein-encoding gene from Phytophthora capsici, vol. 12, pp. 1468-1478, 2013.

Phytophthora capsici is an aggressive plant pathogen that affects solanaceous and cucurbitaceous hosts. Nep1-like proteins (NLPs) are a group of effectors found particularly in oomycetes and considered important virulence factors. We identified an NLP gene (phcnlp1) from the highly virulent P. capsici strain Phyc12 that had an encoded polypeptide of 476-amino acid residues and a predicted molecular mass of 51.75 kDa.

Identification of 18 genes encoding necrosis-inducing proteins from the plant pathogen Phytophthora capsici (Pythiaceae: Oomycetes)

B. Z. Feng, Li, P. Q., Fu, L., Sun, B. B., and Zhang, X. G., Identification of 18 genes encoding necrosis-inducing proteins from the plant pathogen Phytophthora capsici (Pythiaceae: Oomycetes), vol. 10. pp. 910-922, 2011.

Phytophthora capsici is an aggressive plant pathogen that affects solanaceous and cucurbitaceous hosts. Necrosis-inducing Phytophthora proteins (NPPs) are a group of secreted toxins found particularly in oomycetes. Several NPPs from Phytophthora species trigger plant cell death and activate host defense gene expression. We isolated 18 P. capsici NPP genes, of which 12 were active during hypha growth from a Phytophthora stain isolated from pepper (Capsicum annuum) plants in China.
