Zusammenfassung:The invention discloses a mutant, a protein, an expression vector and application of a rice root system elongation control gene OsCYP22 and application of the gene OsCYP22 in control of rice root system elongation, the rice root system elongation is regulated and controlled through deletion of a base in a DNA sequence of the gene OsCYP22, and the nucleotide sequence of the gene OsCYP22 is shown as SEQ ID NO.1. According to the invention, the rice root system elongation control gene OsCYP22 is obtained through regulation and control of deletion of the base in the DNA sequence of the gene OsCYP22. The elongation of the rice root system is regulated and controlled, so that the rice has a short root system phenomenon, and conditions can be created for rice root system improvement and cross breeding or transgenic plant development. 本发明公开了水稻根系伸长控制基因OsCYP22的突变体、蛋白质、表达载体及其应用,基因OsCYP22在控制水稻根系伸长中的应用,为通过其DNA序列中碱基的缺失,调控水稻根系的伸长,所述基因OsCYP22的核苷酸序列如SEQIDNO:1所示,本发明通过调控基因OsCYP22的DNA序列中碱基的缺失,调控水稻根系的伸长,使水稻出现短根系现象,可以为水稻的根系改良和杂交育种
