- A chromosome 16 deletion conferring a high sucrose phenotype in soybeanOstezan, Alexandra; Prenger, Elizabeth M.; Rosso, Luciana; Zhang, Bo; Stupar, Robert M.; Glenn, Travis; Mian, M. A. Rouf; Li, Zenglu (Springer, 2023-05)Key messageSucrose in soybean seeds is desirable for many end-uses. Increased sucrose contents were discovered to associate with a chromosome 16 deletion resulting from fast neutron irradiation.Soybean is one of the most economically important crops in the United States. A primary end-use of soybean is for livestock feed. Therefore, genetic improvement of seed composition is one of the most important goals in soybean breeding programs. Sucrose is desired in animal feed due to its role as an easily digestible energy source. An elite soybean line was irradiated with fast neutrons and the seed from plants were screened for altered seed composition with near-infrared spectroscopy (NIR). One mutant line, G15FN-54, was found to have higher sucrose content (8-9%) than the parental line (5-6%). Comparative genomic hybridization (CGH) revealed three large deletions on chromosomes (Chrs) 10, 13, and 16 in the mutant, which were confirmed through whole genome sequencing (WGS). A bi-parental population derived from the mutant G15FN-54 and the cultivar Benning was developed to conduct a bulked segregant analysis (BSA) with SoySNP50K BeadChips, revealing that the deletion on Chr 16 might be responsible for the altered phenotype. The mapping result using the bi-parental population confirmed that the deletion on Chr 16 conferred elevated sucrose content and a total of 21 genes are located within this Chr 16 deletion. NIR and high-pressure liquid chromatography (HPLC) were used to confirm the stability of the phenotype across generations in the bi-parental population. The mutation will be useful to understand the genetic control of soybean seed sucrose content.
- Registration of 'S17-2243C': A non-genetically modified maturity group IV soybean cultivar with high yield and elevated oil concentrationChen, Pengyin; Shannon, J. Grover; Lee, Dongho; do Granja, Matheus Ogando; Vieira, Caio Canella; Lee, Yi-Chen; Ali, Md Liakat; do Nascimento, Emanuel Ferrari; Scaboo, Andrew; Crisel, Melissa; Smothers, Scotty; Clubb, Michael; Selves, Stewart; Nguyen, Henry T.; Li, Zenglu; Mitchum, Melissa Goellner; Averitt, Ben; Bond, Jason P.; Meinhardt, Clinton G.; Usovsky, Mariola; Li, Shuxian; Smith, James R.; Gillen, Anne M.; Mengistu, Alemu; Zhang, Bo; Mozzoni, Leandro Angel; Moseley, David (Wiley, 2023-02)'S17-2243C' (Reg. no. CV-557, PI 700003) is a semi-determinate, maturity group IV (relative maturity 4.9), non-genetically modified (non-GM) soybean [Glycine max (L.) Merr.] cultivar developed and released by the University of Missouri-Fisher Delta Research, Extension, and Education Center. S17-2243C was developed to meet the growing demands for new non-GM soybean cultivars with high yield and elevated seed oil content. S17-2243C is resistant to stem canker and charcoal rot and has tolerance to salinity conditions. Seed of S17-2243C has averaged 232 g kg(-1) of oil concentration on a dry weight basis, which was significantly higher than all check cultivars in the 2020 USDA Uniform Soybean Tests, Southern States. S17-2243C was tested against high-yielding private and public soybean cultivars from 2018 to 2021 in 80 locations across 12 states, including Alabama, Arkansas, Illinois, Kentucky, Louisiana, Mississippi, Missouri, North Carolina, Ohio, South Carolina, Tennessee, and Virginia. With high yield potential, broad adaptability, early maturity, elevated seed oil content, and non-GM traits, S17-2243C is an excellent cultivar choice for soybean growers adopting alternative growing systems and benefiting from premium prices offered for non-GM soybean products.
