Characterization and analysis of the promoter region of monodehydroascorbate reductase 4 (CpMDAR4) in papaya.

chromosomes. The observed expression patterns in Arabidopsis thaliana flowers and the expression patterns of CpMDAR4 alleles in papaya flowers suggest that MDAR4 might have a role on development of reproductive organs in papaya, and that it constitutes an important candidate for sex differentiation.
