Polyphenol oxidase in potato. A multigene family that exhibits differential expression patterns.
Polyphenol oxidase (PPO) activity in potato (Solanum tuberosum) plants was high in stolons, tubers, roots, and flowers but low in leaves and stems. PPO activity per tuber continued to increase throughout tuber development but was highest on a fresh weight basis in developing tubers. PPO activity was greatest at the tuber exterior, including the skin and cortex tissue 1 to 2 mm beneath the skin....
متن کاملPerennial peanut (Arachis glabrata Benth.) contains polyphenol oxidase (PPO) and PPO substrates that can reduce post-harvest proteolysis.
BACKGROUND Studies of perennial peanut (Arachis glabrata Benth.) suggest its hay and haylage have greater levels of rumen undegraded protein (RUP) than other legume forages such as alfalfa (Medicago sativa L.). Greater RUP can result in more efficient nitrogen utilization by ruminant animals with positive economic and environmental effects. We sought to determine whether, like red clover (Trifo...
متن کاملPolyphenol oxidase from wheat bran is a serpin.
Polyphenol oxidase (PPO; EC 1.10.3.2) was isolated from wheat bran by a procedure that included ammonium sulfate fractionation, batch adsorption by DEAE-cellulofine, CM-cellulofine column chromatography, DEAE-cellulofine column chromatography, preparative isoelectric focusing, adsorption on the membrane of a Vivapure Q Maxi H spin column, and heat treatment. These procedures led to 150-fold pur...
متن کاملInvestigation of Diversity of Different Agronomic and Morphological Traits in Wild Wheat Relatives
Extended Abstract Introduction and Objective: Wild relatives of wheat are one of the most important genetic resources for use in wheat breeding programs. Therefore, identifying wheat wild relatives and Awareness of the diversity in them, also protecting these species is undeniably effective in expanding the richness of the gene pool and the genetic base of new cultivars and can be a good tool ...
