25. O genero Dahlstedtia Malme : embriologia, sistema reprodutivo e biossistematica
Flowers, fruits and seed abortion was studied in two Brazilian species: Dahlstedtia pinnata e D. pentaphy/la (Leguminosae, Papilionoideae). Such a study was developed through investigations of: 1. floral development, microsporogenesis, ovule and early seed development following open, self- and cross-pollination, in order to compare the results to other papil

27. Visitantes florais de Erythrina speciosa Andr. (Leguminosae)
Inspite of Etythrina species exhibit morphologic attributes for adaptation to pollination by nectarivorous birds mentioned in the literature, E. speciosa is pollinated by lots of bees (Apinae and Meliponinae) which show a great urban occurrence. Systems of E. speciosa floral reproduction, fenology, diversity, frequency and constancy of insects visiting at di

28. Biologia da polinização e reprodutiva de sete especies de Convolvulaceae na caatinga do sertão de Pernambuco
The present work deals with the study of floral phenology/biology and reproduction system of seven species of Convolvulaceae, occurring at Fazenda Catalunha, municipality of Santa Maria da Boa Vista (PE) in the "caatinga" vegetation of the so ealled "sertão Pernambucano". The study was conducted from March 1995 to July 1997. The species considered were: Jac

30. Fenologia, biologia floral, mecanismo de polinização e sistema reprodutivo de duas especies simpatricas de Dichorisandra (Commelinaceae)
The comparative study of phenology, floral biology, pollination mechanism and breeding system of Dichorisandra incurva e D. hexandra (Commelinaceae) was undertaken in secondary and semideciduous forest at Campinas, São Paulo, during 1989 to 1991. The species are sympatric, herbaceous, perennials and andromonoecious, with hermaphrodite and functional male fl

31. Genome Organization of More Than 300 Defensin-Like Genes in Arabidopsis1[w]
Defensins represent an ancient and diverse set of small, cysteine-rich, antimicrobial peptides in mammals, insects, and plants. According to published accounts, most species' genomes contain 15 to 50 defensins. Starting with a set of largely nodule-specific defensin-like sequences (DEFLs) from the model legume Medicago truncatula, we built motif models to se
