Natoniel Franklin de Melo is a researcher at Embrapa Semi-Arid, Brazil, with a Ph.D. in Biological Sciences (Genetics). His research focuses on plant genetic resources, genetics, cytogenetics, biotechnology, and plant breeding, with particular emphasis on species adapted to semiarid environments. He has extensive experience in the characterization, conservation, and use of plant germplasm, especially Passiflora species and other crops of importance to the Brazilian semiarid region. He is also a permanent professor in graduate programs at UEFS and UNIVASF, where he supervises M.Sc. and Ph.D. students. His current research integrates genetic diversity, genomics, cytogenetics, and plant responses to environmental stresses to support germplasm conservation and crop improvement.
