The present invention relates to an isolated DNA encoding fungal MRP
(multidrug resistance associated protein) subfamily of ATP-binding
cassette (ABC) transporter protein which confers organisms with
resistance to and/or accumulation of toxic materials such as heavy metals
and herbicides, vectors containing the isolated DNA, and organisms
transformed with the isolated DNA. Organisms transformed with the fungal
MRP subfamily of ABC transporters of the present invention can be used
for remediation of environment polluted with toxic materials. For
example, the transformed plants can be used for cleaning polluted soil or
water, and thereby providing an environmentally-friendly way to remediate
polluted resources with low cost.
