NOVEL GENE ENCODING RNA HELICASE AND USE THEREOF

摘要

PURPOSE: An RNA helicase gene and environment stress tolerance plant cell or plant body are provided to overexpressed in a plant cell by environmental stress and ensure tolerance to the environmental stress. CONSTITUTION: An RNA helicase is denoted by an amino acid sequence of sequence number 2. A gene encoding the RNA helicase is denoted by sequence number 1. The RNA helicase gene is isolated thorugh RACE PCR(Rapid amplification of cDNA ends polymerase chain reaction) method based on cDNA gene library of a fragment of which expression is induced by low temperature in a soybean. A recombinant expression vector contains RNA helicase gene of sequence number 1. A transformed microorganism is prepared by the recombinant expression vector. The environmental stress is low temperature, moisture, bittern or abscisic acid(ABA).
