Construction of novel vectors for transformation of Lentinula edodes using a chitin synthase gene promoter

Novel vectors (pLCHS-hph and pChG-bar) containing expression unit driving hph as a selectable marker gene by chitin synthase gene promoter were constructed for Lentinula edodes transformation. Expression of the hph gene in random selected transformants was confirmed by RT-PCR method. Thus, both vectors are useful for L. edodes transformation.
