Cadmium and arsenic affect quiescent centre formation and maintenance in Arabidopsis thaliana post-embryonic roots disrupting auxin biosynthesis and transport
The research was focussed on the effects of cadmium (Cd) and arsenic (As), alone or combined, on Arabidopsis
post-embryonic roots, with attention to quiescent centre formation and development in relation to auxin
homeostasis. To the aim, morphological and histochemical analyses were carried out on seedlings, exposed or
not to Cd and/or As, of wild type, and transgenic lines useful for monitoring quiescent centre identity, auxin
localization and cellular influx and efflux. Moreover, auxin levels and expression of the YUC6 auxin biosynthetic
