“…This is supported by prior findings where benzoxazinoid rhizodeposition modulated both bacterial and fungal assemblages within the maize endosphere and rhizosphere, influenced host-herbivore symbiosis and increased host immune responses (Cotton et al, 2019;Hu et al, 2018;Kudjordjie et al, 2019). The conferral of nonhost resistance to P. sojae by common bean (Phaseolus vulgaris) is demarcated by β-1,3-glucan polysaccharide deposition and upregulation of phaseollidin-encoding genes (Bi et al, 2022). Seed exudates of maize and common bean promote nonhost resistance to P. sojae by repulsion of zoospores and dissolution of cysts, respectively (Zhang, Zhao, et al, 2022).…”

Cultivated soybean (Glycine max) is a fabaceous staple crop grown extensively for its forage and oil properties (Anderson et al., 2019).The soybean seed contains all essential amino acids required for human consumption, is enriched with macro-and micronutrients and provides an environmentally friendly protein source for both humans and monogastric livestock operations (Messina, 1999;Michelfelder, 2009). Furthermore, soybean oil contains high levels of unsaturated omega-3, omega-6 and omega-9 fatty acids (Anderson et al., 2019). During the 2017/2018 market year, worldwide soybean production exceeded 346 million tonnes, reflecting a growth of 350% since 1987 (Soybean Meal Info Center, 2018). Over 90% of such production is attributed to five countries: the United States, Brazil, Argentina, China and India (Pagano & Miransari, 2016). In the United States, the soybean sector generates approximately $115 billion (>0.7% of the gross domestic product) and employs 350,000 individuals with a total wage impact exceeding $11.6 billion (United Soybean Board and National Oilseed Processors Association, 2020). For these reasons, local, national and international breeding efforts are placed on economic yield increase and on the enhancement of soybean agronomic characters. Soybean yield and quality are influenced considerably by interactions with microorganisms. Most notably, soybean engages in nitrogen fixation with bacteria within the genera Bradyrhizobium and Sinorhizobium. These mutualistic symbioses culminate in 50% of the

Background Phytophthora sojae, a soil-borne oomycete pathogen, has been a yield limiting factor for more than 60 years on soybean. The resurgence of P. sojae (Phytophthora sojae) is primarily ascribed to the durable oospores found in soil and remnants of the disease. P. sojae is capable of infesting at any growth periods of the soybean, and the succeed infestation of P. sojae is predominantly attributed to long-lived oospores present in soil. Comprehending the molecular mechanisms that drive oospores formation and their significance in infestation is the key for effective management of the disease. However, the existing challenges in isolating and extracting significant quantities of oospores pose limitations in investigating the sexual reproductive stages of P. sojae. Results The study focused on optimizing and refining the culture conditions and extraction process of P. sojae, resulting in establishment of an efficient and the dependable method for extraction. Novel optimized approach was yielded greater quantities of high-purity P. sojae oospores than traditional methods. The novel approach exceeds the traditional approaches with respect to viability, survival ability, germination rates of new oospores and the pathogenicity of oospores in potting experiments. Conclusion The proposed method for extracting P. sojae oospores efficiently yielded a substantial quantity of highly pure, viable, and pathogenic oospores. The enhancements in oospores extraction techniques will promote the research on the sexual reproductive mechanisms of P. sojae and lead to the creation of innovative and effective approaches for managing oomycete diseases.

Background: Phytophthora sojae, a soilborne oomycete pathogen, has been a yield limiting factor for more than 60 years on soybean. The resurgence of P. sojae（Phytophthora sojae）is primarily ascribed to the durable oospores found in soil and remnants of the disease. P. sojae is capable of infesting at any growth periods of the soybean, and the succeed infestation of P. sojae is predominantly attributed to long-lived oospores present in soil. Comprehending the molecular mechanisms that drive oospore formation and their significance in infestation is vital for effectively managing the varied diseases it causes. However, the existing challenges in isolating and extracting significant quantities of oospores pose limitations in investigating the sexual reproductive stages of P. sojae. Results: This study focused on optimizing and refining the culture conditions and extraction process of P. sojae, leading to the establishment of an efficient and dependable method for extracting this organism. Optimized novel approachyielded greater quantitiesof high-purity P. sojae than traditional methods. Fortunately, the viability of newly approached oospores did not differ significantly from that of the traditional one, as much the same survival and germination rates of new oospores were detected in deficiency obstructs project implementation (MTT) and plate coating assays. Moreover, in potting experiments, no drastically difference in the pathogenicity of oospores was conducted between the novel and traditional method. Conclusion: Consequently, the proposed method for extracting P. sojae oospores efficiently yields a substantial quantity of highly pure, viable, and pathogenic oospores. The enhancements in oospore extraction techniqueswill promote the research on the sexual reproductive mechanisms of P. sojaeand lead to the creation of innovative and effective approaches for managing oomycete diseases.
