1. Estudos anatomicos e ultra-estruturais da organogenese in vitro de Passiflora edulis Sims f. flavicarpa Deg / Anatomy and structural studies of in vitro organogenesis of Passiflora edulis Sims f. flavicarpa Deg
Meristemoids are responsible for the in vitro organogenesis expression. They may be formed from the explant (direct organogenesis) or from callus (indirect organogenesis). Once in vitro organogenesis is a prerequisite for developing micropropagation strategies and genetic transformation in plants, the ultrastructural analysis of the cells involved in such re

3. The DNA of ciliated protozoa.
Ciliates contain two types of nuclei: a micronucleus and a macronucleus. The micronucleus serves as the germ line nucleus but does not express its genes. The macronucleus provides the nuclear RNA for vegetative growth. Mating cells exchange haploid micronuclei, and a new macronucleus develops from a new diploid micronucleus. The old macronucleus is destroyed
