Phytophthora sojae Pathotype Distribution and Fungicide Sensitivity in Michigan

Plant Disease, 2022
Identifying the pathotype structure of a Phytophthora sojae population is crucial for the effective management of Phytophthora stem and root rot of soybean (PRR). P. sojae has been successfully managed with major resistance genes, partial resistance, and fungicide seed treatments.

Effect of a benzothiadiazole on inducing resistance of soybean to Phytophthora sojae

Protoplasma, 2012
Effects of benzothidiazole (BTH), an inducer of resistance, were examined in a compatible interaction of soybean seedlings and Phytophthora sojae using electron microscopy and quantitative real-time polymerase chain reaction (qRT-PCR) techniques. Seedlings were sprayed with BTH 2 days before inoculation of hypocotyls with zoospore suspension of P ...

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.

A survey of soybean germplasm for resistance to Phytophthora sojae

Euphytica, 2010
Phytophthora root and stem rot of soybean caused by Phytophthora sojae is a destructive disease affecting soybean production regions throughout the world. The utilization of resistant cultivars is the most economical and environmentally safe method for controlling this disease.

Soybean flavonoid effects on and metabolism by Phytophthora sojae

Phytochemistry, 1993
Abstract Various soybean flavonoids were examined for their effects on the growth and development of Phytophthora sojae and for their metabolism by P. sojae . Three classes of molecules were identified based on their effects on growth. Coumestrol, biochanin A, genistein, naringenin and isorhamnetin were inhibitory at concentrations of 60-120 μM ...

Phytophthora sojae Resistance in Soybean: Isoflavonoids as Weapons

Physiologia Plantarum
ABSTRACT Isoflavonoids, which are abundant in soybeans, increase the utility value of soybean products and mediate plant defenses against diverse stresses. In this study, integrated transcriptomic and ultra‐performance liquid chromatography (UPLC) analyses revealed that Phytophthora sojae

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%.

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.

Phytophthora sojae . [Distribution map].

Distribution Maps of Plant Diseases, 2005
Abstract A new distribution map is provided for Phytophthora sojae [Phytophthora megasperma f.sp. glycinea] Kaufm. & Gerd. Hosts: Soyabean (Glycine max). Information is given on the geographical distribution in Argentina, Australia, New South Wales, Queensland, Victoria, Canada, British ...
