Resumen:
Two different strategies
of gene transfer based on A.
rhizogenes and A. tumefaciens have been developed for C. glauca,
and the 35S promoter has been shown to
be a good candidate for constitutive expression in the genus Casuarina. These
results pave the way for the introduction of agronomically useful traits into
actinorhizal trees, which play an important role in reforestation and soil reclamation
in developing countries. Moreover, transgenic trees are a major tool
in the study of the regulatory mechanisms that control the expression of
the actinorhizal symbiotic genes, in dissecting the roles of specific proteins in
nodule development, and in comparing the regulatory mechanisms of
legume and actinorhizal symbiotic genes. A deeper understanding of the different
types of nitrogen-fixing nodules will help to develop future strategies to
modify lateral root development on non-symbiotic plants to enable some to associate
with nitrogen-fixing bacteria.
