“…These studies show that a mutually beneficial interaction exists between bees and soybean fields. Soybean fields provide a source of nectar in midwestern agricultural landscapes (Lin et al 2022), and in the reverse direction, significant increases in crop yield are associated with the presence of nearby apiaries (Blettler, Fagúndez, and Caviglia 2018;Eric H. Erickson 1975;E. H. Erickson et al 1978;Garibaldi et al 2021).…”

Hybrid breeding for increased vigor has been used for over a century to boost agricultural outputs without requiring higher inputs. While this approach has led to some of the most substantial gains in crop productivity, breeding barriers have fundamentally limited soybean (Glycine max) from reaping the benefits of hybrid vigor. Soybean makes inconspicuous flowers that self-fertilize before opening, and thus are not readily amenable to outcrossing. In this study, we demonstrate that the Barnase/Barstar male sterility/male rescue system can be used in soybean to produce hybrid seeds. By expressing the cytotoxic ribonuclease, Barnase, under a tapetum-specific promoter in soybean anthers, we are able to completely block pollen maturation, creating male-sterile plants. We show that fertility can be rescued in the F1 generation of these Barnase-expressing lines when they are crossed with pollen from plants that express the Barnase inhibitor, Barstar. Importantly, we found that the successful rescue of male fertility is dependent on the relative dosage of Barnase and Barstar. When Barnase and Barstar were expressed under the same tapetum-specific promoter, the F1 offspring remained male-sterile. When we expressed Barstar under a relatively stronger promoter than Barnase, we were able to achieve a successful rescue of male fertility in the F1 generation. This work demonstrates the successful implementation of a biotechnology approach to produce fertile hybrid offspring in soybean.

“…These studies show that a mutually beneficial interaction exists between bees and soybean fields. Soybean fields provide a source of nectar in mid‐western agricultural landscapes (Lin et al ., 2022), and in the reverse direction, significant increases in crop yield are associated with the presence of nearby apiaries (Blettler et al ., 2018; Erickson, 1975a; Erickson et al ., 1978; Garibaldi et al ., 2021). This work strongly indicates that honeybees serve as an ecologically beneficial choice for facilitating soybean outcrossing.…”

“…However, pollinators may still visit crops to collect resources. Bees are known to collect pollen from corn, nectar from cotton, and pollen and nectar from soybeans (Esquivel et al., 2021; Lin et al., 2022). These crops bloom after the spring resource flow, providing a valuable option for bees to obtain valuable nutrients, such as proteins and lipids in pollen and carbohydrates in nectar, while other resources are dwindling as temperatures increase.…”

Sweetpotato (Ipomoea batatas L.) is an important staple crop cultivated in over 100 countries, and the storage roots and vines provide food for humans and livestock. Sweetpotato consumption and demand for its value‐added products have increased significantly in the last two decades and have led to new cultivar development, expansion in acreage, and increased demand in the United States and its export markets. Despite the known nutritional components and other health benefits, further research is needed to characterize the genetic diversity and chemical composition related to their storage root qualities, essential in developing consumer‐preferred cultivars that offer host plant resistance against pests and pathogens. There is a critical need for research on non‐pesticidal control approaches that can provide safe, effective, economical, sustainable, and environmentally sound pest and disease management techniques, especially for socially disadvantaged small farmers in the United States. Moreover, climate change can significantly impact future production practices and yield and may directly or indirectly affect crop pests, weeds, and diseases. In this review, we discuss the current status, challenges, and future approaches associated with sweetpotato production practices; health‐promoting properties of sweetpotato cultivars; value‐added products; genetic diversity and germplasm; pest and disease management; weed and water management; pollination ecology; and other agronomic and cultural practices that may impact sustainable sweetpotato production by small‐scale, organic, and large‐scale growers.
