Abstract
This invention provides lemon CiKNOX I The gene and its application in regulating the ripening of tomato and citrus fruits belong to KNOX Family Class 1 ( KNOX I The gene is a member whose CDS sequence is shown in SED ID NO.1 and whose encoded amino acid sequence is shown in SED ID NO.2. Overexpression or silencing vectors of this gene were constructed, and then transfected into tomatoes and citrus fruits using an Agrobacterium-mediated genetic transformation system. Phenotypic observation and analysis validated the results. CiKNOX I Genes have the function of significantly regulating the fruit ripening process, and this invention provides new gene resources for designing breeding based on the fruit ripening process.
