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.

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.

Glucan synthase of Phytophthora sojae

2002
Glucans, with the (1-3)-b-glucosidic linkage as major feature, are present in most of the higher plants, in many lower plants, as well as in microorganisms (Stone and Clarke, 1992). The synthesis of (1-3)-b-glucan in vivo is catalysed by the enzyme (1-3)-b-glucan synthase (EC 2.4.1.34; UDP-glucose:1,3-b-D-glucan 3-b-D-glucosyl transferase) using UDP ...

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 ...

Hyperparasitism of oospores of Phytophthora megasperma var. sojae

Soil Biology and Biochemistry, 1981
Abstract Hyperparasites of oospores of Phytophthora megasperma Drechs. var. sojae Hildb. were present in each of 15 field soils tested. Maximum numbers of oospores parasitized ranged from 42.5 to 87.5% for flooded soils, and from 25.5 to 73.0% for soils adjusted to 50% water holding capacity; the mean for all soils was 51.5%.

Genetic Crosses between Physiologic Races of Phytophthora sojae

Experimental Mycology, 1993
Bhat, R. G., and Schmitthenner, A. F. 1993. Genetic crosses between physiologic races of Phytophthora sojae. Experimental Mycology 17, 122-129. It was not known if cross-fertilization occurred between races of Phytophthora sojae , a homothallic, diploid fungal pathogen or soybean (Glycinea max).

Inheritance and mapping of 11 avirulence genes in Phytophthora sojae

Fungal Genetics and Biology, 2002
Two new crosses involving four races (races 7, 16, 17, and 25) of the soybean root and stem rot pathogen Phytophthora sojae were established (7/16 cross; 17/25 cross). An F2 population derived from each cross was used to determine the genetic basis of avirulence towards 11 different resistance genes in soybean.

Overexpression of GmSRC2 confers resistance to Phytophthora sojae in soybean

Plant Science
Phytophthora root and stem rot caused by Phytophthora sojae (P. sojae) is one of the most destructive diseases to affect soybean (Glycine max (L.) Merr) production. GmSRC2 that encodes a C2 domain-containing protein can respond to various stresses, however, the molecular mechanism of GmSRC2 in resistance of soybean to P.

The Phytophthora sojae Genome Sequence: Foundation for a Revolution

2014
Phytophthora sojae is a soil-borne microorganism and a plant pathogen that causes stem and root rot of soybean. P. sojae is one of the ~120 species of plant pathogenic eukaryotes within the genus Phytophthora. These organisms are oomycetes, fungus-like organisms in the kingdom Stramenopila.
