Fusarium virguliforme causes the serious disease sudden death syndrome (SDS) in soybean. Host resistance to this pathogen is partial and encoded by a large number of quantitative trait loci, each conditioning small effects. Breeding SDS therefore challenging identification single-gene novel mechanisms becoming priority fight devastating fungal pathogen. In transcriptomic study we identified few putative soybean defense genes, expression which suppressed during F. infection. The...
Overexpression of Glycine max disease resistant 1 (GmDR1) exhibits broad-spectrum resistance against Fusarium virguliforme, Heterodera glycines (soybean cyst nematode), Tetranychus urticae (Koch) (spider mites), and Aphis Matsumura aphids) in soybean. To understand the mechanisms immunity mediated by GmDR1, transcriptomes a strong weak GmDR1-overexpressor following treatment with chitin, pathogen- pest-associated molecular pattern (PAMP) common to these organisms, were investigated. The...
Nonhost resistance is defined as the immunity of a plant species to all nonadapted pathogen species. Arabidopsis (Arabidopsis thaliana) ecotype Columbia-0 nonhost oomycete Phytophthora sojae and fungal Fusarium virguliforme that are pathogenic soybean (Glycine max). Previously, we reported generating pss1 mutation in pen1-1 genetic background well mapping characterization sojae-susceptible gene locus, PSS1. In this study, identified six candidate PSS1 genes by comparing single-nucleotide...
Plants fight-off pathogens and pests by manifesting an array of defence responses using their innate immunity mechanisms. Here we report the identification a novel soybean gene encoding plasma membrane protein, transcription which is suppressed following infection with fungal pathogen, Fusarium virguliforme. Overexpression protein led to enhanced resistance against not only F. virguliforme, but also spider mites (Tetranychus urticae, Koch), aphids (Aphis glycines, Matsumura) cyst nematode...
Non-host resistance (NHR), which protects all members of a plant species from non-adapted or non-host pathogens, is the most common form immunity. NHR provides durable and robust broad-spectrum immunity against non-adaptive pathogens pathogenic to other crop species. In mutant screen for loss Arabidopsis (Arabidopsis thaliana) soybean (Glycine max (L.) Merr.) pathogen Phytophthora sojae, sojae-susceptible 30 (pss30) was identified. The pss30 also susceptible Fusarium virguliforme. PSS30...
Summary Overexpressors of Glycine max disease resistant 1 ( GmDR1 ) exhibits broad-spectrum resistance against Fusarium virguliforme , soybean cyst nematode (SCN), spider mites, and aphids in soybean. To understand the mechanisms immunity mediated by we investigated transcriptomes a strong weak -overexpressors following treatment with chitin, pathogen- pest-associated molecular pattern (PAMP) found these organisms. The exhibited altered expression 6,098 992 genes, respectively, as compared...
