MT and MT trans.enics.to acid indole acetic, cytokinin, gib.erellin, ab.cis.c acid and ethylene were cultivated in nutrient s.lutions.containing different Al concentrations. Root growth elongation was.meas.red and cellular damage was.vis.alized b. s.aining Evans.s.b.ue. The GUs.reporter gene s.aining technique was.us.d to vis.alize hormonal changes.in MT apex root tis.ues. Data indicated that the MT is.s.ns.tive to Al that induced s.gnificant growth inhib.tion and cellular damage. Al concentration of 27 μM was.s.gnificantly toxic, inducing root apex darkening and inhib.tion of root development. The qualitative evaluation of GUs.reporter gene expres.ion s.owed intens. cros.talk among all hormones.s.udied, unders.oring the complexity of s.gnaling induced b. Al in apex roots. Res.lts.point out to a major unders.anding of the hormonal s.gnaling in res.ons. to Al toxicity, which may induce a change of root growth and architecture with growth inhib.tion and cell cons.raints.modulated b. all different hormones.evaluated.
