Phosphite translocation in soybean and mechanisms of Phytophthora sojae inhibition

Pesticide Biochemistry and Physiology, 2021
Although phosphite (Phi)-based fertilizers are used in large quantities in agriculture, the use of Phi-based fungicides against soybean root rot caused by Phytophthora sojae are limited. While, their low toxicity are of high ecological and economic focus.

Soybean sterol composition and utilization by Phytophthora sojae

Phytochemistry, 2001
The sterol fraction of Glycine max (soybean) was found to contain a mixture of 13 major sterols which differed dramatically in composition between seeds and shoots. Typical C4-desmethyl Delta(5)-sterols, including sitosterol, predominate the sterol mixture of shoots, whereas C4-methyl sterol intermediates, cycloartenol and 24(28)-methylene cycloartanol,

The Evolution of Races ofPhytophthora sojaein Australia

Phytopathology, 1996
Isolates of Phytophthora sojae collected between 1979 and 1993 from three soybean-growing regions in eastern Australia and the United States were characterized for virulence and restriction fragment length polymorphisms (RFLPs). A total of 99 isolates were characterized: 84 from Australia and 15 from the United States. In the Australian population of P.

Interspecific hybrids between the homothallic Phytophthora sojae and Phytophthora vignae

Australasian Plant Pathology, 2003
An interspecific cross was attempted between two homothallic species of Phytophthora, P. sojae and P. vignae. From 1640 single-oospore cultures isolated, DNA was extracted from 800, and two interspecific F-1 hybrids (F(1)1121 and F(1)1426) were putatively identified using RAPD markers.

Generating Gene Silenced Mutants in Phytophthora sojae

2018
Phytophthora species are notorious pathogens of plants and cause enormous damage to agriculture. In order to understand Phytophthora pathogenesis, gene silencing and knockout methods are important for the investigation of gene functions. Although CRISPR/Cas9-based gene knockout procedures have been developed in Phytophthora sojae and Phytophthora ...

Inventory and Comparative Evolution of the ABC Superfamily in the Genomes of Phytophthora ramorum and Phytophthora sojae

Journal of Molecular Evolution, 2009
Automated and manual annotation of the ATP binding cassette (ABC) superfamily in the Phytophthora ramorum and P. sojae genomes has identified 135 and 136 members, respectively, indicating that this family is comparable in size to the Arabidopsis thaliana and rice genomes, and significantly larger than that of two fungal pathogens, Fusarium graminearum ...

Comparative proteomic analysis of hyphae and germinating cysts of Phytophthora pisi and Phytophthora sojae

Journal of Proteomics, 2015
The recently described oomycete pathogen Phytophthora pisi causes root rot on pea and faba bean, while the closely related Phytophthora sojae is the causal agent of soybean root and stem rot. Differences in the pathogenicity factor repertoires that enable the two species to have distinct host specificity towards pea and soybean, were studied using ...

Peroxidase Activity in Soybeans Following Inoculation with Phytophthora sojae

Mycopathologia, 2006
The effects of race-specific resistance as conditioned by Rps genes (rps, Rps1-k, Rps2, Rps3, Rps6) in two genetic backgrounds (Williams & Harosoy) on accumulation of soluble peroxidases were determined by a soybean peroxidase capture assay (SPCA) after inoculation with P. sojae races 2, 7, or 25.

Soybean Isoflavones Trigger a Calcium Influx in Phytophthora sojae

Fungal Genetics and Biology, 1999
Both the motile zoospores and the hyphal germ tubes of Phytophthora sojae respond chemotropically to the soybean isoflavones daidzein and genistein. The role of Ca(2+) in the cellular response to these host signals was investigated by using X-ray microanalysis of cells to monitor net changes in cellular levels of Ca(2+) and by quantifying the effects ...

Phytophthora sojae effectors orchestrate warfare with host immunity

Current Opinion in Microbiology, 2018
Phytophthora sojae is one of the most damaging plant pathogens of soybean. To aid establishment of a compatible interaction with its host, P. sojae deploys many secreted effectors. These effectors act either in the apoplastic space to cope with hostile conditions or inside of host cells to reprogram host physiology favoring pathogen growth.
