Soybean cyst nematode Heterodera glycines (SCN) is a major threat to global soybean production. Effective management of this disease is dependent on the development of resistant cultivars. Two SCN HG Types, 7 and 1.3.4.7. were previously identified as prevalent H. glycines populations in Northeast China. In order to evaluate soybean cultivars resis...

Phytochrome (Phy)‐regulated light signaling plays important roles in plant growth, development, and stress responses. However, its function in rice defense against sheath blight disease (ShB) remains unclear. Here, we found that PhyB mutation or shade treatment promoted rice resistance to ShB, while resistance was reduced by PhyB overexpression. Fu...

Knowledge about virulent phenotypes of Heterodera glycines Ichinohe, 1952 (soybean cyst nematode, SCN) is essential for breeding resistant cultivars and managing this nematode. Heilongjiang Province is the major soybean producing region in China. SCN has been reported in 63 regions in Heilongjiang Province. To determine the prevalence and virulence...

Key message: A novel QTL (qSCN-PL10) for SCN resistance and related candidate genes were identified in the soybean variety Pingliang xiaoheidou, and plant basal immunity seems to contribute to the SCN resistance. Soybean cyst nematode (SCN, Heterodera glycines Ichinohe) is one of the most devastating soybean pests worldwide. The development of hos...

BACKGROUND The soybean cyst nematode (SCN, Heterodera glycines) is the most devastating and yield‐limiting pest in soybean worldwide. With the increasing awareness of environmental protection, biological control becomes more and more urgent. The Bacillus megaterium Sneb207 was previously shown the ability to inhibit the movement of SCN, but little...

We studied the bioactive compound of the fungus Simplicillium chinense strain Snef5, isolated from its culture filtrate. Following purification by chromatography, the structure of the secondary metabolite, identified as 2,6-pyridinedicarboxylic acid, was determined by spectroscopic methods (IR, ¹H, and ¹³C NMR) and scanning electron microscopy (SEM...

Phlox drummondii Hook., belonging to the Polemoniaceae, is an annual herbaceous ornamental plant that is used for urban landscaping in the north of China. Unfortunately, the parasitic powdery mildew pathogen could thrive on P. drummondii, which could render the plant unsightly and weakened. During summer and the following autumn 2017, more than 90%...

A strain H-2 was isolated by diluted solution method from soybean continuous cropping soil sample,its morphological,physiological and biochemical characteristics were identified and 16S rDNA was analyzed. The result showed that it was Streptomyces parvus. Fermentation filtrates of Streptomyces parvus at different concentrations were evaluated for n...

Soybean cyst nematode (SCN), Heterodera glycines and Bacillus induced gene expression alterations in plant host play a vital role in root invasion. The true differences in the level of genes of interest were accurately measured by real-time PCR (RT-qPCR). However, internal reference genes were indispensable for the namalization of transcription. Re...

We used the Illumina HiSeqTM 2000 system to analyze the transcriptomes of the disease-resistant soybean variety Huipizhiheidou (ZDD2315) and the susceptible soybean variety Liaodou 15 before and after the infection of the soybean cyst nematode (SCN), race 3 (HG type -7). According to the reference genome, we found that 10 days after inoculation wit...

Rhg1 (resistance to Heterodera glycines 1) is an important locus that contributes to resistance against soybean cyst nematode (SCN; Heterodera glycines Ichinohe), which is the most economically damaging disease of soybean worldwide. Simultaneous overexpression of three genes encoding a predicted amino acid transporter, an alpha‐soluble N‐ethylmalei...

In disease-suppressive soil, plants rely upon mutualistic associations between roots and specific microbes for nutrient acquisition and disease suppression. Notably, the transmission of suppressiveness by the cysts of sugar beet cyst nematode from suppressive to conducive soils has been previously observed in greenhouse trials. However, our current...

Soybean cyst nematode (SCN, Heterodera glycines Ichinohe) is a serious soybean pathogen worldwide. HG Type 0 had been a predominant SCN in Heilongjiang province, the largest soybean (Glycine max L.) producing region in China. Recently, increased virulence on resistant cultivars originally developed for resistance to HG Type 0 was observed in fields...

Soybean cyst nematode (SCN) is the most damaging soybean pest worldwide. To improve soybean resistance to SCN, we employed a soybean seed-coating strategy through combination of three rhizobacterial strains, including Bacillus simple, B. megaterium and Sinarhizobium fredii at various ratios. We found seed coating by such rhizobacterial strains at a...

Effect of the three strains on the number of cysts. Plants were treated with Bacillus simple (Sneb545), B. megaterium (Sneb482) and Sinarhizobium fredii (Sneb183) under three field conditions in Daqing City of Heilongjiang Province, Anda County of Heilongjiang Province and Kangping County of Liaoning Province, respectively in 2011. The data in the...

Plant R2R3-MYB transcription factors play crucial roles in stress responses. We previously isolated a R2R3-MYB homolog from sweet cherry cv. Hong Deng, designated PacMYBA (GenBank accession No. KF974774). To explore the role of PacMYBA in the plant stress response, we heterologously expressed PacMYBA in transgenic Arabidopsis thaliana plants. In a...

The response of ascorbate peroxidase (APX) gene to nematode (Heterodera glycines) infection was studied in roots of soybean cultivars - the susceptible Liaodou 15 and Liaodou 15 coated with bio-control bacteria Sneb545. The expression profile of APX in coated Liaodou 15 infected with H. glycines, which generates oxidative stress, was analyzed. Real...

The relationship of Soybean Trypsin Inhibitor (STI) and soybean resistance to Soybean cyst nematode (Heterodera glycines Ichinohe, SCN) were studied by two soybean resistant varieties and two susceptible soybean cultivars. The assay results showed that the activity of STI with inoculation was change extensively in the soybean roots comparing with t...

Soybean cyst nematode, Heterodera glycines Ichinohe, is the most destructive pest of soybean (Glycine max) worldwide, including China. H. glycines virulence phenotypes can be described in two ways. One is the race determination test that uses four soybean lines to categorize H. glycines into 16 “races” (3). The HG type designation is similar, but a...
