Auxin content and growth patterns in auxin-dependent and auxin-autotrophic plant cell and tissue cultures

Open publisher page 9 citations

Abstract

Endogenous concentrations of indol-3-ylacetic acid (IAA) in auxin-autotrophio crown gall tissue cultures are presented in relation to culture growth rate and to tissue IAA levels in auxin-dependent cultures maintained on IAA as auxin source. Cellular levels of synthetic auxins absorbed from culture media were monitored in auxin-dependent cell cultures exhibiting selectivity in growth response to exogenous auxins. The results are used in modelling culture growth patterns and changes in intracellular auxin content.
