1. Aspectos estruturais e ultraestruturais da androsporogênese e androgametogênese de Rhynchospora pubera (vahl) Boeckeler (Cyperaceae)
Cyperaceae é considerada a terceira maior família de monocotiledôneas compreendendo cerca de 120 gêneros, com 4.000 a 5.000 espécies com distribuiçãocosmopolita. No Brasil, existem de 500 a 600 espécies organizadas em 44 gêneros,preferencialmente de terrenos úmidos e alagados. Esta família apresenta algumascaracterísticas citológicas importantes

2. O interesse de professores pelo estudo da biologia: manifestações atuais e memórias
In this research, we seek to understand the relationship between personal interests for the study of the different Biology themes and experiences in the learning of Science over the life of Biology and Science teachers. To this end, we carried out theoretical and empirical studies that integrate qualitative and quantitative methods about: a) translation and

10. Expression of Engineered Nuclear Male Sterility in Brassica napus (Genetics, Morphology, Cytology, and Sensitivity to Temperature).
A dominant genetic male sterility trait obtained through transformation in rapeseed (Brassica napus) was studied in the progenies of 11 transformed plants. The gene conferring the male sterility consists of a ribonuclease gene under the control of a tapetum-specific promoter. Two ribonuclease genes, RNase T1 and barnase, were used. The chimaeric ribonuclease

11. Revertants of Dominant Mutations Associated with the Antennapedia Gene Complex of DROSOPHILA MELANOGASTER: Cytology and Genetics
Using X-ray mutagenesis we have induced and recovered phenotypic revertants of four dominant mutations thought to be associated with the Antennapedia complex of Drosophila melanogaster. These include seven revertants of Antennapedia-73b (Antp73b), six of Extra Sex Combs of Wakimoto (Scxw), three of Deformed (Dfd) and one of Humeral (Hu). Fifteen of the 17 re
