Auxin transport on cellular level by means of mathematical-modelling-motivated research

Popis výsledku v původním jazyce

Polar auxin transport is an important spatial and temporal signaling mechanism in plant tissues. Mathematical modelling has been frequently used to explore many regulatory mechanisms in plant tissues. Contrastingly we describe the transport of auxin at the cellular level using basic techniques of mathematical modelling and the characterization of auxin transport mechanisms demonstrated earlier by Delbarre et al. (1996) in tobacco cells. Our results indicate that 1-naphthaleneacetic acid (NAA) is strongly and rapidly metabolized during accumulation experiments in BY-2 tobacco cells which might have led to serious underestimation of auxin efflux carriers transport capacity for NAA. In contrast, metabolism of 2,4-dichlorophenoxyacetic acid (2,4-D) making2,4-D an ideal tool for probing auxin transport. Hence, using 2,4-D accumulation data and modified mathematical model of auxin transport we characterize and validate parameters of 2,4-D transport on cellular level.
