Abstract
To identify salt resistance genes from burma mangrove (Bruguiera gymnorhiza), the gene expression profiling under salt-stress was performed using oligo microarray. Functional analysis of the salt-responsive genes using transgenic Agrobacterium revealed that the genes similar to zinc-finger transcription factor gene STO in Arabidopsis and ankyrin repeat protein gene confer resistance to 350 mM NaCl on Agrobacterium. STO was reported to confer salt resistance on Saccharomyces cerevisiae and the over-expresser of Arabidopsis. Production of their transgenic plants is on the progress. Furthermore, to identify salt resistance genes from burma mangrove which are not induced by salt treatment, production and functional screening of transgenic Agrobacterium and Arabidopsis expressing full-length cDNAs from burma mangrove are also in progress.
