Role of auxin efflux in apical hook development

Popis výsledku v původním jazyce

Apical hook of dark-grown seedlings is a simple structure, whose differential growth is regulated by hormones. Apical hook develops soon after germination and is maintained until the seedling emerges from the soil, and the hook opens upon its exposure tothe light. We observed that progress of apical hook through individual developmental phases depends on dynamic and asymmetric distribution of auxin regulated by auxin efflux carriers of PIN family. Several PIN genes exhibit specific and only partially overlapping expression patterns. Genetic manipulation of individual PINs activities differentially interferes with particular stages of the hook development. Thus, specific combinations of different PINs are required for the progress of the apical hook through developmental phase. Detailed analysis of the ethylene regulated apical hook development suggests that at least part of the ethylene effect might be mediated through interaction with auxin and ethylene-dependent regulation of the au
