The present invention relates to a gene being capable of modifying resistance against a heavy metal or salt, or accumulation properties, a recombination vector including the genes, and a transformant using the recombination vector. A gene having heavy metal resistance and accumulation properties includes a sequence encoding a transmembrane protein having five times repeated similar four transmembrane domains. A recombination vector includes the gene having heavy metal resistance and accumulation properties, and further includes a salt or drought resistance gene having at least one selected from the group consisting of a sequence encoding an ABC transporter including twice repeated six transmembrane domains and ATP-binding domains; a sequence encoding a protein including a GTP-binding domain and a CaaL domain (geranylgeranylation motif) being capable of transferring its position from a cytoplasm to cell membrane
