the enzyme is localized predominantly in the conical cells of the inner epidermal layer and, to a much lesser extent, in the cells of the outer epidermis of flower petal lobes. The enzyme is also located in the inner epidermis of the corolla tube with little protein detected in the outer epidermis and in the yellow hairs within the tube on the bees way to the nectar
brenda
expression of mRNA about half the level in petal
brenda
expression of only 2fold higher than in pistil, where lowest level of mRNA expression is observed

highest BAMT enzyme activity is found after 4 h of petal opening i.e., at 12 a.m. of night. Although the first peak is observed at 4 p.m. (4 h before petal opening), after reached at its highest level of activity, BAMT activity gradually decreases as found in the emission of methylbenzoate, where the highest emission is at 2 a.m. of night, i.e. 6 h of petal opening
