Candidate Gene, SmCPR1, Encoding CPR1 Related to Plant Height of the Eggplant Dwarf Mutant dwf

Eggplant is a vegetable crop with high economic value that cultivated worldwide. The dwarf mutant an important germplasm material has been extensively used in breeding. However, no eggplant mutants have reported, and little known regarding the genes responsible for dwarfism eggplant. In this study, we isolated (dwf) from ethyl methyl sulfonate (EMS)-induced library. Genetic analysis revealed dwf was caused by single recessive gene. A candidate gene SmCPR1, encoding cytochrome P450 reductases (CPR1), identified bulked segregant (BSA). Mutation G to at 8216 bp of SmCPR1 resulted mutation amino acid valine isoleucine. results KASP Sanger sequencing further support conclusion dwf. Moreover, activity significantly increased dwf, which might be response
