PURPOSE: A laver-derived high temperature resistant protein in bacteria, algae, and plants and a gene encoding the protein are provided to enhance gene expression and laver production. CONSTITUTION: A protein which is isolated from laver and has high temperature resistance contains an amino acid sequence of sequence number 1. The protein is a 15kDa protein with 144 amino acids. A gene encoding the protein is a cDNA having a sequence of sequence number 2. A recombinant vector contains the gene, HTR2. A transformant is prepared by introducing the recombinant vector to the host such as bacteria, sea algae, or plants.
