- disease complex causes considerable yield losses in soybean production worldwide. As one of the major pathogens, T. W. Hobbs (syn. ) is not only the primary agent of Phomopsis seed decay but is also one of the agents of Phomopsis pod and stem blight and Phomopsis stem canker. We performed both PacBio long-read sequencing and Illumina short-read sequencing and obtained a genome assembly for the strain YC2-1, which was isolated from soybean stem with Phomopsis stem blight disease. The 63.1 Mb genome assembly contains 87 scaffolds, with a minimum, maximum, and N scaffold length of 20 kb, 4.6 Mb, and 1.5 Mb respectively, and a total of 17,407 protein-coding genes. The high-quality data expand the genomic resource of species and will provide a solid foundation for a better understanding of their genetic diversity and pathogenic mechanisms.[Formula: see text] Copyright © 2021 The Author(s).

Cultivated sunflower (Helianthus annuus L.) is a globally important oilseed crop that is grown primarily in the Northern Great Plains region of the United States. In September 2018, sunflower stems exhibiting brown stem lesions centered on the leaf axils and accompanied by pith degradation, consistent with symptoms of Phomopsis stem canker (PSC) disease, were sampled from a commercial field of approximately 520 hectares in Polk County, MN (47°50'24" N, 96.

A survey of Diaporthe/Phomopsis Complex (DPC) species was carried out on 479 asymptomatic soybean (Glycine max (L.) Merrill) seed samples collected from commercial soybean fields in the states of Santa Catarina (20 counties) and Rio Grande do Sul (41 counties), in the 2020/21 (n=186), 2021/22 (n=138) and 2022/23 (n=155) seasons from 120 cultivars. The seeds were provided by seed producers who collected according to the sampling standard of the Ministry of Agriculture, Livestock and Food Supply.
