It is well known that photoreceptors are involved in gravitropism, but poorly known their involving in other tropisms. NaCl is always regarded as a stress factor, but it is also the stimulating factor for the hydrotropism of roots. The role of the photoreceptors that are located both in shoots and roots in these phenomena are not still established. We have previously tested how the mutants on photoreceptors could be involved in root growth of Arabidopsis on the early plant growth stages under different salt conditions Today we are studding the root architecture of the mature (18-30 DAG) plants in Petri dishes under full vertical illumination (22ºC,16-h photoperiod, 70 µmol m–2s–1) in several mutants on photoreceptors of Arabidopsis, growing on MS/2, supplied with 100 mM NaCl. The point is that stable to the salt Arabidopsis mutants on photoreceptors continue root growth during 30 DAG, but differently to the gravity vector.
