摘要：

The PR-10 protein family contains proteins related to pathogenesis and allergenic proteins. They are acidic proteins, with an intracellular localization, usually members of a multigene family and ubiquitous among plant kingdom. They contain a highly conserved motif, identified as a phosphate binding site. Even if the biological function of these proteins is still unknown, many indicators seem to favour the hypothesis of an RNAse activity. Moreover, one of them seems to be a cytokinin specific binding protein. Besides, PR-10 protein expression induction under cytokinin treatment was observed with the Catharanthus roseus CrPR-10a protein. Here, we present the evidence of a significative increase of endogenous cytokinin contents in leaves of transgenic Tobacco plants over-expressing the CrPR-10a protein.
