[Transgenic Tobacco plants expressing bacterial genes encoded the thermostable glucanases].

It is shown that bacterial genes for thermostable beta-glucanases are expressed retaining their activity and substrate specificity. The leader peptide of the carrot extensin exerts effective secretion of the bacterial enzymes into the intercellular space of the plant tissue. Expression of the bacterial gene for beta-1,3-glucanase in plant tissues alters their morphogenetic potential.
