Abstract:We examined the effects of hypergravity on nuclear positioning in epidermal cells of azuki bean (Vigna angularis) epicotyls. The nucleus was positioned almost in the center of the cell under 1 G conditions. When the epicotyls were exposed to basipetal hypergravity by centrifugation, the nucleus was displaced toward the centrifugal side of the cell in a linear dose-response manner. The nuclear displacement started within 20 min by exposure to basipetal hypergravity at 300 G, and reached ca. 35% from the centrif… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
