Phytophthora root and stem rot of soybean caused by Phytophthora sojae(P.sojae)is a devastating disease that affects soybean[Glycine max(L.)Merr.]all over the world.S-phase kinase-associated protein 1(SKP1)proteins are key members of the SKP1/Cullin/F-box protein(SCF)ubiquitin ligase complex and play diverse roles in plant biology.However,the role of SKP1 in soybean against the phytopathogenic oomycete P.sojae remains unclear.In this study,a novel member of the soybean SKP1 gene family,GmSKP1 which was significantly induced by P.sojae,was reported.The expression of GmSKP1 was simultaneously induced by methyl jasmonate(MeJA),salicylic acid(SA)and ethylene(ET),which might suggest an important role for GmSKP1 of plant in responses to hormone treatments.Functional analysis using GmSKP1 overexpression lines showed that GmSKP1 enhanced resistance to P.sojae in transgenic soybean plants.Further analyses showed that GmSKP1 interacted with a homeodomain-leucine zipper protein transcription factor(GmHDL56)and a WRKY transcription factor(GmWRKY31),which could positively regulate responses to P.sojae in soybean.Importantly,several pathogenesis-related(PR)genes were constitutively activated,including GmPR1a,GmPR2,GmPR3,GmPR4,GmPR5a and GmPR10,in GmSKP1-OE soybean plants.Taken together,these results suggested that GmSKP1 enhanced resistance to P.sojae in soybean,possibly by activating the defense-related PR genes. 展开更多

The internal transcribed spacer (ITS) region (ITS1, ITS2 and 5.8S rDNA) of the nuclear ribosomal DNA (nrDNA) was amplified via the PCR method in seventeen different isolates of Phytophthora sojae using the common primers of the ITS of fungi. Around 800 bp- 1,000 bp fragments were obtained based on the DL2000 marker and the sequences of the PCR products were tested. Taking isolate USA as outgroup, the phylogenetic tree was constructed by means of maximum parsimony analysis, and the genetic evolution among isolates was analyzed. The results showed that there is a great difference between the base constitution of ITS 1 and ITS2 among various isolates. The seventeen isolates are classified into three groups, and the isolates from the same region belong to the same group, which shows the variation in geography. 展开更多

[ Objective] The paper was to screen the antagonistic strain against Phytophthora sojae with biocontrol potential, and provide basis for searching control measures and designing new control strategies against P. sojae. [ Method] The rhizosphere soil of soybean was collected from three different places in Heilongjiang Province, and various soil microorganisms were isolated. Dual culture method was used to screen the microorganism with antagonistic effect against P. sojae. On this basis, the growth inhibition rate of the microorganism with stronger antagonistic effect against P. sojae was determined, and its control effect against P. sojae was also measured. [ Result] A strain of bacterium with relatively good antagonistic effect was isolated from soil, and named as strain B048. Dual test showed that the growth inhibition rate of antagonistic bacterium 11048 against P. sojac reached 97.5%. Antagonistic endurance tests showed that the width of inhibition zone was still 20.0 mm after dual culture with P. sojac for21 d. In potting experiment, the control effect of B048 against P. sojae was 100%. The antagonistic bacterium was primarily identified to be Bacillus pumilus through morphology and 16S rDNA sequence analysis. [Condusion] The antagonistic bacterium B048 had good prospect to be developed as the biocontrol bacterium against P. sojae. 展开更多

Phytophthora sojae Kanfman and Gerdemann (P. sojae) is one of the most prevalent pathogens and causes Phytophthora root rot, which limits soybean production worldwide. Development of resistant cultivars is a cost-effective approach to controlling this disease. In this study, 127 soybean germplasm were evaluated for their responses to Phytophthora sojae strain Pm28 using the hypocotyl inoculation technique, and 49 were found resistant to the strain. The hypocotyl of P1, P2, F1, and F2:3 of two crosses of Ludou 4 (resistant)×Youchu 4 (susceptible) and Cangdou 5 (resistant)×Williams (susceptible) were inoculated with Pm28, and were used to analyze the inheritance of resistance. The population derived from the cross of Ludou 4×Youchu 4 was used to map the resistance gene (designated as Rps9) to a linkage group. 932 pairs of SSR primers were used to detect polymorphism, and seven SSR markers were mapped near the resistance gene. The results showed that the resistance to Pm28 in Ludou 4 and Cangdou 5 was controlled by a single dominant gene Rps9, which was located on the molecular linkage group N between the SSR markers Satt631 (7.5 cM) and Sat_186 (4.3 cM). 展开更多

In order to clarify the differential response of Phytophthora sojae to the seed exudates of host soybean and non-host maize and understand the relationship between seed exudates and host selectivity of Phytophthora sojae, non-host maize Suiyu 23 and susceptible host soybean Sloan seed exudates were collected to measure their influence on mycelial growth, formation and germination of oospores, chemotaxis, encystment and germination of zoospores of Phytophthora sojae. The results showed that nonhost maize seed exudates exhibited repellency to zoospores of Phytophthora sojae, it also could significantly inhibited Phytophthora sojae mycelial growth, formation of oospores compared with the control;compared with host soybean, non-host maize seed exudates could significantly inhibited Phytophthora sojae mycelial growth, formation and germination of oospores, germination of cysts, which indicated that the seed exudates was the critical factor to host selectivity of Phytophthora sojae and the maize seed exudates was closely related to its non-host resistance. 展开更多

Soybean root and stem rot caused by Phytophthora sojae is a destructive disease worldwide. Using genetic resistance is an important and major component in the integrated pest management of this disease. To understand molecular mechanisms of root and stem rot resistance in soybeans, the gene and protein expression in hypocotyls and stems of variety Suinong 10 carrying resistance genes Rps1a and Rps2 was investigated by using mRNA differential display reverse transcription PCR and two-dimensional electrophoresis at 0, 0.5, 1, 2, and 4 h after inoculation with P. sojae race 1. The results of the comparison of gene and protein expression showed that at least eight differential fragments at the transcriptional level were related to metabolic pathway, phytoalexin, and signal transduction in defense responses. Sequence analyses indicated that these fragments represented cinnamic acid 4-hydroxylase gene, ATP b gene coding ATP synthase b subunit and ubiquitin-conjugating enzyme gene which upregulated at 0.5 h post inoculation, blue copper protein gene and UDP-N-acetyl-a-D-galactosamine gene which upregulated at 2 h post inoculation, TGA-type basic leucine zipper protein TGA1.1 gene, cyclophilin gene, and 14-3-3 protein gene which upregulated at 4 h post inoculation. Three resistance-related proteins, a-subunit and b-subunit of ATP synthase, and cytochrome P450-like protein, were upregulated at 2 h post inoculation. The results suggested that resistance-related multiple proteins and genes were expressed in the recognition between soybean and P. sojae during zoospore germination, penetration and mycelium growth of P. sojae in soybean. 展开更多

To elucidate the differential gene expression patterns in soybeans during infection by Phytophthora sojae,a cDNA library for suppression subtractive hybridization (SSH) was constructed with cDNAs from soybean cultivar Suinong 10 treated with sterile distilled water as the driver and cDNAs from Suinong 10 inoculated with P.sojae as the tester.A total of 2 067 recombinant colonies from the SSH library were randomly picked,amplified,and sequenced.After discarding 312 poor quality expressed sequence tags (EST),1 755 high quality ESTs were assembled and edited to 1 384 tentatively unique genes (TUG),in which,586 showed significant homology to known sequences,and 798 had low homology or no match with the known sequences.A cDNA microarray containing 307 singletons from the 586 TUGs and 222 singletons from the 798 TUGs was developed to characterize differentially expressed cDNAs in the SSH library,and eight cDNAs were identified to be up-regulated after microarray analysis and then confirmed by real-time PCR.They were homologous to the protein 10,and were also related to some proteins in disease resistance response,such as pathogen-related protein,phenylalanine ammonia-lyase,isoflavone reductase,WRKY transcription factor 31,major allergen Pru ar 1,and pleiotropic drug resistance protein 12.Most of the up-regulated cDNAs encode enzymes of phytoalexin biosynthesis and pathogenesis-related proteins involved in plant disease resistance.Here,we fist reported the Pru ar 1 in soybeans.The findings of this research have contributed to better understanding of soybean resistance to P.sojae at the molecular level. 展开更多

Soil-borne pathogen Phytophthora sojae is an oomycete that causes devastating damage to soybean yield. To mine original resistant genes in soybean is an effective and environmentally-friend approach controlling the disease. In this study, soybean proteins were extracted from the first trifoliolates infected by predominant P. sojae race 1 and analyzed by twodimensional gel electrophoresis. Nineteen differently-expressed protein spots were detected, and 10 of them were further applied for Matrix-Assisted Laser Desorption/Ionization Time of Flight Mass Spectrometry Assay. One protein containing a dirigent (DIR) domain was identified and belonged to the DIR-b/d family. Therefore, it was named as GmDRR1 (Glycine max Disease Resistance Response 1). Then, GmDRR1 gene was pathologically confirmed to be involved in the resistant to P. sojae in soybean. GmDRR1-GFP (green fluorescent protein) fusion proteins localized in the cell membrane. qRTPCR results showed GmDRR1 gene expressed differently in P. sojae resistant- and susceptible-soybean cultivars. By the promoter analysis, we found a haplotype H8 was existing in most resistant soybean varieties, while a haplotype H77 was existing in most susceptible soybean varieties. The H77 haplotype had seven SNPs (C to A, G to C, C to A, T to A, T to C, T to C, and T to A) and two single nucleotide insertions. The results supported that the expression difference of GmDRR1 genes between P. sojae resistant- and susceptible-soybean cultivars might depend on the GmDRR1 promoter SNPs. The results suggested that GmDRR1 was a dirigent protein involved in soybean resistant to P. sojae and paved a novel way for investigation of the molecular regulatory mechanism of the defense response to P. sojae in soybean. 展开更多

Phytophthora sojae infection severely impairs soybean production. We previously identified a dirigent protein, Gm DRR1(Glycine max Disease Resistant Response 1), that increases soybean resistance to P.sojae. However, the molecular basis of Gm DRR1 function remained largely uncharacterized. In the present study, analysis of Gm DRR1-RNAi, Gm DRR1-overexpressing, and CRISPR/Cas9-derived Gmdrr1 mutant lines revealed that Gm DRR1 expression significantly restricted P. sojae growth. Combining coimmunoprecipitation with liquid chromatography–tandem mass spectrometry revealed a Gm DRR1-interacting protein, Gm DRR2, which is homologous to Gm DRR1. An E-coniferyl alcohol coupling assay indicated that Gm DRR1 promotes the synthesis of(+)-pinoresinol, which helps to protect plants from P. sojae. The Gm NAC1(Glyma.05 G025500) transcription factor bound to the Gm DRR1 promoter both in vitro and in vivo to upregulate Gm DRR1 expression. Soybean resistance to P. sojae was increased by overexpression of Gm NAC1. Our findings suggest a novel signaling pathway involving a NAC transcription factor that mediates soybean resistance to P. sojae. Specifically, Gm NAC1 directly induces Gm DRR1 expression to increase resistance of soybean plants to P. sojae. 展开更多

Soybean Phytophthora root rot (Phytophthora sojae) is a severe disease all over the world. Soybean germplasm from central and southern China for resistance has been evaluated by American researchers on a large scale. P. sojae has been found frequently in northeast of China in recent years, but not systematic evaluation of soybean germplasm for resistance has occurred there. By means of hypocotyl inoculation, 922 cultivars/lines from northeast of China were screened and evaluated for their response to race 1, and 25 of P. sojae. Generally resistance was less frequent in northeast of China than in central and southern China. Five cultivars/lines were identified that confer resistant responses to race 1, 3, 8, 25 and four additional isolates of P. sojae. These cultivars/lines may provide valuable sources of resistance for future breeding programs. 展开更多

To estimate the impact of crop rotation on the pathotype and genetic structure of Phythophthora sojae in fields, 372 isolates of P. sojae were obtained from long-term localisation experimental fields in Heilongjiang Province of China. The hypocotyl inoculation method was used to characterize the virulence of P. sojae on 13 differential cultivars, and the amplified fragment length polymorphism(AFLP) technique was used to analyze difference in the genetic structure of P. sojae. The results indicated that an abundant diversity of genetic structures and pathotypes of P. sojae, a more uniform distribution of pathotypes and less dominance of pathotypes occurred in corn-soybean and wheat-soybean rotation fields than in a continuous soybean mono-cropping field. These findings suggested that P. sojae did not easily become the dominant race in rotation fields, which maintain disease resistance in soybean varieties. Therefore, the results of this study suggested that Phytophthora stem and root rot of soybeans could be effectively controlled by rotating soybeans with non-host crops of corn and wheat. 展开更多

野生大豆(Glycine soja)是栽培大豆的祖先,为东亚特有种,大部分分布在中国。我们采用52对SSR引物和10个植物学性状,以遗传丰富度和Simpson多样性指数为指标,对来自中国3个地理生态区域涉及24个省区的196份野生大豆所构成的代表性样本的... 野生大豆(Glycine soja)是栽培大豆的祖先,为东亚特有种,大部分分布在中国。我们采用52对SSR引物和10个植物学性状,以遗传丰富度和Simpson多样性指数为指标,对来自中国3个地理生态区域涉及24个省区的196份野生大豆所构成的代表性样本的遗传变异进行了研究,以期从分子水平和表型水平两个层面上揭示中国野生大豆遗传多样性和地理生态特异性。结果表明:中国野生大豆群体SSR位点的等位基因平均丰富度(NA)和平均Simpson多样性指数(H)分别为16.1和0.852,高于栽培大豆(NA=11.4,H=0.773),野生群体的遗传多样性明显高于栽培群体。3个地理生态群体中南方群体多样性最高(NA=12.9,H=0.842),黄淮海群体最低(NA=11.4,H=0.805),东北群体居中(NA=12.5,H=0.834)。群体间存在遗传分化,不同群体具有不同的特异等位基因,位点AW132402(A2连锁群)、Satt522(F)、satt150(M)、Sat_332(D1a)、Satt046(K)、sct_190(K)等的一些等位基因只在特定群体出现,表现出群体分化后的生态特异性。中国野生大豆植物学性状的群体变异丰富,平均Simpson多样性指数为0.710。地理群体间存在分化,最明显的是生育期性状的分化,反映了地理、光照和温度等生态因子的选择作用,其中南方地理群体多样性最高(H=0.671)。SSR分子标记和植物学性状所获结果相对一致,表明中国野生大豆地理群体间性状分化有其遗传分化的基础。 展开更多

In order to determine an appropriate sampling strategy for the effective conservation of wild soybean (Glycine soja Sieb. et Zucc.) in China, a natural population from Jiangwan Airport in Shanghai was studied for its genetic diversity through the inter-simple sequence repeat (ISSR) marker analysis of a sample set consisting of 100 randomly collected individuals. A relatively large genetic diversity was detected among the samples based on estimation of DNA products amplified from 15 selected ISSR primers, with the similarity coefficient varying from 0.17 to 0.89. The mean expected heterozygosity (He) was 0.171 4 per locus, and Shannon index (1) was 0.271 4. The Principal Coordinate Analysis (PCA) further indicated that genetic diversity of the Jiangwan wild soybean population was not evenly distributed, instead, was presented by a mosaic or clustered distribution pattern. Correlation study between genetic diversity and number of samples demonstrated that genetic diversity increased dramatically with the increase of number of samples within 40 individuals, but the increase became slow and rapidly reached a plateau when more than 40 individuals were included in the analysis. It is concluded that (i) a sample set of approximately 35-45 individuals should be included to represent possibly high genetic diversity when conservation of a wild soybean population ex situ is undertaken; and (ii) collection of wild soybean samples should be spread out as wide as possible within a population, and a certain distance should be kept as intervals among individuals for sampling. 展开更多
