Sucrose Metabolism in the Culm of Transgenic Sugarcane with Reduced Soluble Acid Invertase Activity
Transgenic derivatives of sugarcane cultivar Q117, with reduced acid invertase activity, were used to investigate the role of this enzyme in sucrose metabolism in the sugarcane culm. Despite more than 70% reduction in the level of acid invertase activity in the immature internodes, no significant changes in either sucrose load or purity were evident. Radiolabelling experiments indicated no sign...
متن کاملon the equivalence of constructed-response and multiple-choice : stem-equivalent, stem non-equivalent but content equivalent, and stem and content non-equivalent items in reading comprehension using multifaceted rasch
the present study investigated construct equivalence of multiple choice (mc) and constructed response (cr) item types across stem and content equivalent mc and cr items (item type ‘a’), non-stem-equivalent but content equivalent mc and cr items (item type ‘b’), and non-stem and non-content equivalent mc and cr items (item type ‘c’). one hundred seventy english-major undergraduates completed mc ...
The location of acid invertase activity and sucrose in the vacuoles of storage roots of beetroot (Beta vulgaris).
Vacuoles were isolated from freshly cut slices of the storage roots of beetroot (Beta vulgaris), and from slices that had been washed in aerated water for 1-3 days. The unique vacuolar location of betanin permitted the use of a correlative method to determine whether sucrose and acid invertase were located in the vacuoles. The specific content (the activity of the enzyme or amount of substrate ...
متن کاملAn-Overview on invertase in sugarcane
Saccharum officinarum is one of the most cultivated hybrid varieties among the sugarcane varieties. In sugarcane plant sucrose is the major carbohydrate which can be stored and transported. Different physiological and biochemical studies on this crop report that invertase activity and sucrose concentration some how are key limiting step in the process of sucrose accumulation. Significant effort...
متن کاملRegulation of invertase levels in Avena stem segments by gibberellic Acid, sucrose, glucose, and fructose.
Gibberellic acid and sucrose play significant roles in the increases in invertase and growth in Avena stem segments. About 80% of invertase is readily solubilized, whereas the rest is in the cell wall fraction. The levels of both types of invertase change in a similar manner in the response to gibberellic acid and sucrose treatment. The work described here was carried out with only the soluble ...
