1. In vitro multiplication of Eucalyptus hybrid via temporary immersion bioreactor: culture media and cytokinin effects
Abstract This study aimed to assess the influence of culture medium and cytokinin type on in vitro multiplication of an Eucalyptus grandis x E. urophylla hybrid clone via temporary immersion bioreactor (TIB®). JADS, modified MS at a (NO3ˉ):(NH +) ratio, and WPM were used as liquid media; and 6-benzilaminopurine (BAP), kinetin (KIN), and thidiazuron (TDZ) w

2. Induction and Morpho-Ultrastructural Analysis of Organogenic Calli of a Wild Passionfruit
This work studied a new protocol for organogenic calli induction and characterization of the morphology and ultrastructure of callogenesis in leaf explants of Passiflora gibertii N. E. Brown, a native passion fruit species from Brazil. Calli induction was performed in different growth conditions (light and dark), different MS medium salt concentrations (MS a

3. Anatomy of the nectaries, colleter, and stgma of Rodriguezia venusta (Lindl.) Rchb. f. (Orchidaceae) / Anatomia dos nectarios, do coleter e do estigma de Rodriguezia venusta (Lindl.) Rchb. f. (Orchidaceae)
Rodriguezia venusta is an orchid with ornamental potential, native to Brazil and Peru. This specie belongs to subtribe Oncidiinae that is in Epidendroideae, the notorioas biggest Orchidaceae s subfamily. Although the wide morphology and taxonomy studies on this family, the works concerning anatomy are rare, specially focusing the secretory structures, in ord

4. Estudo de alguns eventos do florescimento do cafeeiro relacionados a fatores do ambiente / Study of some coffee tree flowering events related to environmental factors.
The coffee tree flowering involves several events related with the factors of plant and environmental characteristics. A better comprehension on the flowering events and the relations among those factors can improve the knowledge in cropping practices, mainly in irrigation techniques, aiming to promote the homogeneity on the flowering and, consequently, on t

5. Fenologia, biologia floral e polinização de três espécies de Flacourtiaceae na região de Manaus - AM
The present study describes aspects of the floral biology, pollination and phenology of Lindackeria paludosa (Benth.) Gilg., Casearia grandiflora Camb. and C. javitensis Kunth (Flacourtiaceae). The work was carried out in Manaus in two areas, one located on the Campus of the Universidade Federal do Amazonas and the second on the Campus of the Instituto Nacio

6. Interações em tres niveis troficos envolvendo galhas de Neolasioptera cupheaeGagne (Diptera, Cecidomyiidae) e seus parasitoides em Cuphea carthagenensis (Jacq.) Macbride (Lythraceae)
Neolasioptera cupheae Gagné (Diptera, Cecidomyiidae) induces a stem gall on the herbaceous pIant Cuphea carthagellellsis (Jacq.) Macbride (Lythraceae). The gall is covered with a dense layer of glandular trichomes which secret a thicky and adhesive substance. In this study we described biological aspects of the gall maker. its population fluctuation and the

7. The Identification of Transposon-Tagged Mutations in Essential Genes That Affect Cell Morphology in Saccharomyces Cerevisiae
The yeast Saccharomyces cerevisiae reproduces by budding, and many genes are required for proper bud development. Mutations in some of these genes cause cells to die with an unusual terminal morphology--elongated or otherwise aberrantly shaped buds. To gain insight into bud development, we set out to identify novel genes that encode proteins required for pro

8. Suppression of Malignancy and Differentiation in Melanotic Melanoma Cells*
Tumorigenicity of mouse melanoma cells is reduced or lost upon growth in vitro in 1 to 3 μg/ml of 5-bromodeoxyuridine (BUdR). The rate of growth is very little affected by these concentrations. The morphology of the cells is altered, such that the cells grow in a flattened, often fibroblastic monolayer, showing contact inhibition, instead of the rounded, mu

9. On the Origin of Branches in Escherichia coli
Some Escherichia coli strains with impaired cell division form branched cells at high frequencies during certain growth conditions. Here, we show that neither FtsI nor FtsZ activity is required for the development of branches. Buds did not form at specific positions along the cell surface during high-branching conditions. Antibiotics affecting cell wall synt

10. The Glc7p-Interacting Protein Bud14p Attenuates Polarized Growth, Pheromone Response, and Filamentous Growth in Saccharomyces cerevisiae
A genetic selection in Saccharomyces cerevisiae for mutants that stimulate the mating pathway uncovered a mutant that had a hyperactive pheromone response pathway and also had hyperpolarized growth. Cloning and segregation analysis demonstrated that BUD14 was the affected gene. Disruption of BUD14 in wild-type cells caused mild stimulation of pheromone respo

11. The Carboxy Terminus of Simian Virus 40 Large T Antigen Is Required To Disrupt the Yeast Cell Cycle
Wild-type and J domain mutant simian virus 40 large T antigens alter the cell cycle and bud morphology of Saccharomyces cerevisiae. In contrast, yeast cells expressing mutant T antigen lacking the carboxy-terminal 150 aa exhibit normal morphology, indicating that this region of T antigen is required for cell cycle disruption.

12. Yeast RHO3 and RHO4 ras superfamily genes are necessary for bud growth, and their defect is suppressed by a high dose of bud formation genes CDC42 and BEM1.
RHO3 and RHO4 are members of the ras superfamily genes of the yeast Saccharomyces cerevisiae and are related functionally to each other. Experiments using a conditionally expressed allele of RHO4 revealed that depletion of both the RHO3 and RHO4 gene products resulted in lysis of cells with a small bud, which could be prevented by the presence of osmotic sta
