Auxin efflux carrier activity and auxin accumulation regulate cell division and polarity in tobacco cells

Abstract

Division and growth of most types of in vitro-cultured plant cells require an external source of auxin. In such cultures, the ratio of external to internal auxin concentration is crucial for the regulation of the phases of the standard growth cycle. In this report the internal concentration of auxin in suspension-cultured cells of Nicotiana tabacum L… (More)
