Interaction between Phytophthora megasperma f. sp. glycinea and Glycine max
The Glycine max (soybean): Phytophthora megasperma f. sp. glycinea (Pmg) pathosystem has served as a model for elucidating the mechansim of incompatibility in gene-for-gene interactions. This interaction was accurately and precisely investigated on the taproots of aeroponically-grown soybeans. An …

Temperature Induced Compatibility In The Host-pathogen Interaction Between Soybean And Phytophthora Megasperma Fsp Glycinea
… (incompatible) or virulent (compatible) races of Phytophthora megasperma f. sp. glycinea to give resistant or susceptible responses. In a search for factors involved in specificity, advantage was taken of the fact that the resistant interaction between soybean cv Altona and Phytophthora megasperma …

Inhibition of Mycelial Growth and Reproduction of Phytophthora Megasperma F. Sp. Glycinea by Trichothecin Produced by Trichothecium Roseum
… harzianum, or Trichothecium roseum and Phytophthora megasperma f. sp. glycinea (Pmg) was studied. Culture filtrates of T. roseum inhibited mycelial growth as well as zoosporangenesis of Pmg in culture and soil, but not those of G. roseum and T. harzianum. The antagonism by culture …

Some Physiological Aspects Of The Soybean - Phytophthora Megasperma F Sp Glycinea Interaction, With Special Reference To The Phytoalexin, Glyceollin
… of soybean cultivars (Glycine max) with Phytophthora megasperma f.sp. glycinea (Pmg) races is governed by single host genes (Rps) and is consistent with the "gene-for-gene" hypothesis. Using the near isogenic cultivars Harosoy ({dollar}rpssb1{dollar}, susceptible to race 1) and Harosoy 63 …

Evaluation of Soil Compaction, Plant Density, and Resistance to Phytophthora Root Rot in Soybeans
Phytophthora root rot, caused by Phytophthora megasperma f. sp. glycinea Kuan and Erwin, is a soil-borne fungal disease of soybean Glycine max (L.) Merr. . Studies were conducted to determine the effects of soil compaction on phytophthora incidence, to determine if reduced soybean stand due to …

The Effect of Foliar and Root Pathogens of Soybean on Selected Host Parameters
… Fumigation followed by inoculation of soil with Phytophthora megasperma var. sojae (PMS) provided a method to evaluate the effect of PMS infection, but symptom development was affected by environmental parameters. PMS infected plants had reduced transpiration rates and yields.

Restriction fragment length polymorphism mapping of quantitative and qualitative traits in soybean
… Rps genes that confer resistance in soybean to phytophthora root rot caused by Phytophthora megasperma Drechs. f. sp. glycinea Kuan and Erwin were mapped with RFLP markers in the second study. The mapping was conducted by first screening, with RFLP markers, a series of near isogenic lines …

Mapping and Characterization of Phytophthora sojae and Soybean Mosaic Virus Resistance in Soybean
Phytophthora sojae, the causal organism of stem and root rot, and <i>Soybean mosaic virus</i> (SMV) cause two of the most highly destructive diseases of soybean (<i>Glycine max</i> L. Merr). <i>P. sojae</i> can be managed either through deployment of race-specific resistance or through quantitative …
