Engineering cottonseed for use in human nutrition by tissue-specific reduction of toxic gossypol.
Global cottonseed production can potentially provide the protein requirements for half a billion people per year; however, it is woefully underutilized because of the presence of toxic gossypol within seed glands. Therefore, elimination of gossypol from cottonseed has been a long-standing goal of geneticists. Attempts were made to meet this objective by developing so-called "glandless cotton" i...
متن کاملBreeding and genetics Modifying gossypol in cotton (Gossypium hirsutum L.): a cost effective Method for small seed samples
cotton (Gossypium hirsutum L.) and related species all contain gossypol, a polyphenolic compound that is an integral part of the cotton plant’s self-defense system against insect pests and possibly some diseases. gossypol also has been reported to have antitumor activity, medicinal effects, and contraceptive properties. However, the compound can be toxic to animals, which limits the usefulness ...
متن کاملLowering seed gossypol content in glanded cotton (Gossypium hirsutum L.) lines
Cottonseed is a rich source of high quality protein, but its value as an animal feed is limited by gossypol, a toxic polyphenolic compound contained in glands located throughout the plant. This compound helps protect the plant from pests. Totally glandless varieties have been developed, but not adopted as these plants are left vulnerable to pests. This study describes a breeding strategy to dec...
متن کاملFood and Feeding Quality of Cottonseed
The research objective for production of quality cottonseed that has been a major concern of cottonseed researchers for many years is to: "Identify the genetic variability of cottonseed composition, determine the genetic control of cottonseed traits, and develop preferred cotton· seed quality germplasm; develop an understanding of developmental processes of the plant that leads to improved cott...
متن کاملCottonseed And Gossypol: Effects On Lactation, Reproduction And Health Of Dairy Cows
Two major types of cottonseed are available in the southwest US, Upland and Pima. Upland is a high-lint type of cottonseed that is generally fed whole, while Pima is a delinted type of cottonseed that is often fed either cracked or ground to improve nutrient utilization. The nutrient composition of the two types of cottonseed differs, and Pima is often considered nutritionally superior because ...
