Abstract
The application provides application of Arabidopsis COL4 gene in improving UV-B resistance of plants. The application obtains an overexpression vector of Arabidopsis COL4 gene through genetic engineering technology, and thus obtains an overexpression strain of Arabidopsis, and finally obtains a homozygous strain of Arabidopsis COL4 gene overexpression through screening; the homozygous strain of Arabidopsis COL4 gene overexpression is characterized in that anthocyanin accumulation is increased under UV-B irradiation, root growth is better than that of a wild type, and good UV-B resistance is achieved. The application confirms through experiments that the Arabidopsis COL4 gene has potential application value in improving UV-B resistance of plants, and lays a good theoretical and application foundation for cultivating an UV-B-resistant and high-yield crop variety by using the Arabidopsis COL4 gene.
