phytophthora root and crown rot of soybean is known as a destructive disease of soy-bean both through out the world and in iran. physiologic races of phytophthora soja were determined in this research and also a fast, accurate and simple method for inoculation of soybean to test race specific resistance. during the years　2001-4, infected soybean plants at different growth stages were collected ...

Plant endo-beta-1,3-glucanases (EGases) degrade the cell wall polysaccharides of attacking pathogens and release elicitors of additional plant defenses. Isozymes EGaseA and EGaseB of soybean differ in susceptibility to a glucanase inhibitor protein (GIP1) produced by Phytophthora sojae, a major soybean pathogen. EGaseA, the major elicitor-releasing isozyme, is a high-affinity ligand for GIP1, w...

SUMMARY Transcripts encoding elicitin-like protein domains were identified from similarity searches of Phytophthora sojae expressed sequence tags and were characterized with regard to molecular structure and elicitor activity. The P. sojae elicitin family consists of at least nine genes with products similar to previously described elicitins (SOJA-2, SOJB, SOJ2, SOJ3, SOJ5, SOJ6 and SOJ7) or hi...

Fukuda (1933) proposed that G. gracilis is an intermediate evolutionary type between G. soja to G. max, but Some annual Glycine accessions are intermediate between the Hymowitz (1970) suggested that G. gracilis is a hybridstandard phenotypes of Glycine max (L.) Merr. and Glycine soja Sieb. & Zucc. and have been labeled semiwild. Few studies have ization product of G. max and G. soja. The latter...

Wild and cultivated species of soybeans have coexisted for 5000 years in China. Despite this long history, there is very little information on the genetic relationship of Glycine soja and G. max. To gain insight into the major events in the history of the subgenus Soja, we examined 20 simple sequence repeat (SSR) markers of a large number of accessions (910). The results showed no significant d...

The level of linkage disequilibrium (LD) is a major factor to determine DNA polymorphism pattern of a population and to construct high-resolution maps useful in localizing and gene cloning of complicated traits. Here, we investigated LD level of three soybean populations with different genetic backgrounds and taxonomic status of G. gracilis by comparing the DNA polymorphism patterns of four hig...

The objective of this study was to identify quantitative trait loci (QTL) affecting fitness of hybrids between wild soybean (Glycine soja) and cultivated soybean (Glycine max). Seed dormancy and seed number, both of which are important for fitness, were evaluated by testing artificial hybrids of G. soja × G. max in a multiple-site field trial. Generally, the fitness of the F1 hybrids and hybrid...

Genes for Bowman-Birk type protease inhibitors (BBIs) of wild soja (Glycine soja) and soybean (Glycine max) comprise a multigene family. The organization of the genes for wild soja BBIs (wBBIs) was elucidated by an analysis of their cDNAs and the corresponding genomic sequences, and compared with the counterparts in the soybean. The cDNAs encoding three types of wild soja BBIs (wBBI-A, -C, and ...

Drug selection should be a rational process that embraces the principles of evidence-based medicine. However, many factors may affect the choice of agent. It is against this background that the System of Objectified Judgement Analysis (SOJA) process for rational drug-selection was developed. This article describes how the information on which the SOJA process is based, was researched and proces...
