In summary, HbMlo1 was first cloned and characterized from
rubber tree in this study. HbMlo1 encoded a typical Mlo protein with
a seven trans-membrane domain. Phylogenetic analysis revealed
that HbMlo1 belonged to the phylogenetic clade II with 100% bootstrap
support value. HbMlo1 was preferentially expressed in leaf
tissue. Furthermore, HbMlo1 transcript was significantly induced
by various phytohormones ,H2O2, and wounding treatments. Under
drought stress, HbMlo1 exhibited a complex expression pattern.
However, HbMlo1 expression did not significantly change during
powdery mildew infection. These results suggested that HbMlo1
might play a role in phytohormone signaling and abiotic stress
response processes, but not to pathogen infections. These findings
enable us to further investigate the roles of Mlo genes in rubber tree
