Abstract

Fifty-two plant species, covering some Gymnosperms and all the key groups of Angiosperms, were chosen for surveying their intrinsic beta-glucuronidase-like activities. Histochemical (overnight incubation) and qualitative fluorometric (24 h incubation) assays indicated that, with few exceptions, such activities were detected in certain part(s) of the fruit walls, seed coats, endosperms or, especially, the embryos of the tested plants. Most of such activities in the excised immature embryos of soybean and string bean disappeared after one to a few days' in vitro culturing. Such activities in the intact mature seeds of these two species diminished also during germination process. The vegetative organs of seedlings/mature plants usually lack such activities. The enzyme(s) responsible for such activities was antigenically dissimilar to E. coli beta-glucuronidase.
