Soil borne pathogens that affect soybean seed and seedlings result in significant losses due to reduced stands and costs associated with replanting. This study compared the response of these 40 SoyNAM parent genotypes to seed- and seedling-rot pathogens, Fusarium graminearum, Phytophthora sojae, Globisporangium ultimum var. ultimum, G. ultimum var. sporangiiferum, and G. irregulare groups 1, 2 and G. cryptoirregulare. None of the parental genotypes conferred high levels of resistance to F. graminearum nor G. ultimum var. sporangiiferum. Of the 40 parental genotypes, 15 were resistant to P. sojae OH1 (vir 7) indicating they contain Rps genes while the remaining (including the common parent IA 3023) do not have Rps genes. Based on inoculations with known P. sojae pathotypes, Rps1c was the most common followed by Rps1a as both Rps genes confer resistance to isolates OH4 (vir 1a, 1c, 7) and OH25 (vir 1a, 1b,1c, 1k, 7). Eight of the SoyNAM parents had higher levels of partial resistance to P. sojae than Conrad (cultivar with moderate resistance). There was moderate resistance to G. ultimum var ultimum among the 40 parents and to G. irregulare subpopulations among the 6 parents that were evaluated. The SoyNAM parental lines and populations are an excellent resource available for soybean breeders to advance the development of new cultivars with improved resistance to some soilborne pathogens.","PeriodicalId":20251,"journal":{"name":"Plant Health Progress","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2023-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47374714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The symptoms were similar to previously reported whitefly-transmitted viruses such as cucurbit leaf crumple virus (CuLCrV), cucurbit yellow stunting disorder virus (CYSDV), squash vein yellowing virus (SqVYV). Another potential virus of interest was the cucurbit chlorotic yellows virus (CCYV) that was recently reported on watermelon in Florida. Symptomatic leaves were tested by RT-PCR with coat protein (CP) gene-specific (GS) primers for CuLCrV, CYSDV, CCYV, and for SqVYV with a nuclear inclusion protein (NIa) GS primers. Amplification for CuLCrV, CYSDV, and CCYV were detected in squash and pumpkin samples. The CCYV amplicons were further sequenced and compared with available CCYV sequences. The NCBI BLAST analysis revealed similarities of the RdRP (100%), HSP70h (99.75%), and CP (99.75%) to the Shanghai CCYV isolate (RNA KY400636 and RNA2 KY400633).

Passalora arachidicola (Pa), the causal agent of early leaf spot (ELS), and Nothopassalora personata (Np), the causal agent of late leaf spot (LLS), were inoculated separately or together on three historically dominant cultivars, Florunner (1970 to 1996), Georgia Green (1996 to 2008) and Georgia-06G (2008 to present), and on one susceptible cultivar, Georgia Valencia. These results suggest that the transition from Florunner to Georgia Green may have contributed to the historical shift from LLS to ELS predominance observed in the 1990s, with sporulation potential as a possible mechanistic explanation. There was no evidence that Georgia-06G contributed to the resurgence of LLS in recent years. A negative association between ELS and LLS, where LLS is more suppressed in the presence of ELS, demonstrates that the dynamics of the ELS-LLS disease patterns is complex. Understanding factors that contribute to disease predominance will improve predictive abilities and support the development of cultural practices and fungicide programs specific to which pathogen is expected to dominate.","PeriodicalId":20251,"journal":{"name":"Plant Health Progress","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2023-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47235128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, crape myrtle is constantly subjected to multiple pathogen attacks, which severely affect the yield and quality and cause economic losses. In June 2019, foliar virus-like symptoms chlorosis and mosaic were observed on plants of crape myrtle in Yangzhou city, Jiangsu Province, east China. Leaf samples were collected from symptomatic crape myrtle plants. All samples were assayed by western blotting using polyclonal antiserum to cucumber mosaic virus (CMV), and tobacco mosaic virus (TMV) and double-antibody sandwich (DAS)-ELISA assay for watermelon mosaic virus (WMV). Results revealed the all samples reacted positively with the WMV but negative with CMV and TMV. Next, RT-PCR was employed to confirm the obtained serological results. An amplicon of 288 bp was obtained from all the samples. Nucleotide BLAST analysis revealed that the sequence had 98.25-100% nucleotide identity to 8 isolate WMV sequences available in GenBank. A pathogenicity assay was conducted using virus-free Nicotiana benthamiana seedlings inoculated with sap extracted from symptomatic crape myrtle leaves. Systemic infection of WMV was also confirmed in N. benthamiana by RT-PCR. On the basis of the data from serological and molecular analyses, the virus was identified as WMV. To our knowledge, this is the first report of WMV on crape myrtle in Jiangsu Province in China.","PeriodicalId":20251,"journal":{"name":"Plant Health Progress","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2023-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42403523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To control SSR, multiple management practices have been studied and implemented to reduce SSR development and preserve yield. This study examined the effects of integrating soybean seeding rates and pesticide programs under nitrogen fertilizer applications in the form of urea (46-0-0) that may occur due to management for other crops, such as corn. From ten site-years between 2020 and 2021, low seeding rates decreased SSR development while also decreasing yields and partial profits. The effect of pesticide applications on SSR development was influenced by both seeding rates and nitrogen applications. Consistently, applications of the fungicide, Endura, reduced SSR to the lowest levels, while also maintaining the highest yields and partial profits. Soybeans grown with nitrogen applications experienced increased SSR development, and decreased yields and partial profits. Overall, this work suggests that using low seeding rates and fungicides improves the management of SSR, and using nitrogen fertilizer applications can result in greater SSR development and decreased economic returns, especially in fields with a history of SSR.","PeriodicalId":20251,"journal":{"name":"Plant Health Progress","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2023-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45446731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
