Se1 Allele Cuts Carotenoids, Tocotrienols in Sweet Corn
A recent study released by the University of Wisconsin-Madison sheds light on how the sugary enhancer1 (se1) allele influences the nutritional profile of yellow sweet corn (Y1 sugary1 su1). The findings highlight a significant reduction in key nutrients, including carotenoids and tocotrienols, in sweet corn varieties carrying this genetic variant.
Carotenoids, known for their antioxidant properties and contributions to eye health, and tocotrienols, a form of vitamin E with potential cardiovascular benefits, play critical roles in human nutrition. The study demonstrates that the se1 allele, which enhances sweetness, has a trade-off in reducing the levels of these essential nutrients.
This research provides valuable insights for plant breeders and agricultural scientists aiming to balance sweetness with nutritional value in sweet corn cultivars. The findings emphasize the need for a strategic approach in crop improvement programs to develop varieties that cater to consumer preferences while maintaining their health benefits.
The study is a step forward in understanding the genetic factors that influence both the taste and nutritional quality of sweet corn, offering pathways for future innovations in agricultural science and food production.

Established in 1903, the American Society for Horticultural Science is recognized around the world as one of the most respected and influential professional societies for horticultural scientists. ASHS is committed to promoting and encouraging national and international interest in scientific research and education in all branches of horticulture.
Comprised of thousands of members worldwide, ASHS represents a broad cross-section of the horticultural community – scientists, educators, students, landscape and turf managers, government, extension agents and industry professionals. ASHS members focus on practices and problems in horticulture: breeding, propagation, production and management, harvesting, handling and storage.
