Soluble forms of invertases in mungbean (Vigna radiata) during germination and development stages of various tissues

Three varieties of mungbean NM 19-19, NM 20-21 and NM 121-125 were germinated to investigate the changes in activity of soluble forms of invertases with respect to their pH optima during germination and various developmental stages of leaves, flowers and pods. High alkaline invertase activity was pr...

Summary:Three varieties of mungbean NM 19-19, NM 20-21 and NM 121-125 were germinated to investigate the changes in activity of soluble forms of invertases with respect to their pH optima during germination and various developmental stages of leaves, flowers and pods. High alkaline invertase activity was present after 24 h of germination in all varieties and during subsequent stages of germination and it was replaced by acid invertase. Acid invertase seemed to be present in tissues undergoing rapid growth and development, where hexoses were quickly utilized and sucrose was rapidly hydrolyzed. Immature stages of leaves, flowers and pods primarily contained acid invertase but as the growth proceeded, alkaline invertase or neutral invertase were appeared alone or along with acid invertase activity. Alkaline invertase was supposed to hydrolyze the sucrose in cells of storage organ.
