Effect of Chilling Temperatures on the Activities of Glyoxysomal and Mitochondrial Enzymes from Castor Bean Seedlings 1

Abstract

Castor bean (Ricinus communis L.) is included among the group of plants sensitive to chilling temperatures. Seedlings of this species were shown to exhibit visible symptoms of this injury, as well as impaired radicle growth and storage product mobilization. Respiration of intact seedlings and oxidation of succinate by isolated mitochondria displayed discontinuities in Arrhenius plots of their reaction velocities, characteristic of chilling species. However, gluconeogenic glyoxysomal enzymes do not display such discontinuities, indicating that there is probably no functional relationship between these enzymes and the glyoxysomal membrane.
