1. VERNALIZANDO PRÉ-TRANSPLANTES MELHORAM AS CARACTERÍSTICAS AGRONÔMICAS DE GENÓTIPOS DE MORANGO EM CONDIÇÃO TROPICAL
RESUMO O rendimento da planta de morango melhora si acumularem uma certa quantidade de horas frias, o que não ocorre naturalmente em condições de clima tropical e subtropical. Este estudo avaliou características agronómicas de 14 genotipos de morango sometidos a vernalização das mudas, produzidas em vasos, antes do transplante a campo. As mudas foram

3. Potato genotypes reaction to early blight and late blight in organic cultivation
RESUMO: O manejo de doenças nos cultivos convencionais de batata requer emprego de maior quantidade de produtos fitossanitários e de maior toxicidade em relação ao cultivo orgânico, que pode acarretar riscos a saúde humana e impacto ambiental. Este trabalho teve como objetivo avaliar o rendimento e a reação de genótipos de batata à requeima e à p

4. Expressão de zif-268 durante a aquisição, evocação e extinção de uma memória aversiva
In the behavioral paradigm of discriminative avoidance task, both short and long-term memories have been extensively investigated with behavioral and pharmacological approaches. The aim of the present study was to evaluate, using the abovementioned model, the hippocampal expression of zif-268 - a calcium-dependent immediate early gene involved with synaptic

5. Potato clones immune to PVY from crosses between cv. Chiquita and clones simplex for the Ry allele. / Clones de batata imunes ao PVY derivados da cv. Chiquita x clones simplex para o alelo Ry
Clonal families were obtained from biparental crosses between cv Chiquita and clones (named JUG) immune to PVX and PVY. Cultivar Chiquita presents high levels of resistance to early blight (Alternaria solani) and has good general combining ability for this trait. The objective was to generate clones with resistance to the fungus and the viruses diseases. All

6. 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

7. Production of Reactive Oxygen Species, Alteration of Cytosolic Ascorbate Peroxidase, and Impairment of Mitochondrial Metabolism Are Early Events in Heat Shock-Induced Programmed Cell Death in Tobacco Bright-Yellow 2 Cells1
To gain some insight into the mechanisms by which plant cells die as a result of abiotic stress, we exposed tobacco (Nicotiana tabacum) Bright-Yellow 2 cells to heat shock and investigated cell survival as a function of time after heat shock induction. Heat treatment at 55°C triggered processes leading to programmed cell death (PCD) that was complete after

8. Static and dynamic actions of cytoplasmic Ca2+ in the adaptation of responses to saturating flashes in salamander rods.
1. In order to study the relative contribution to light adaptation of the various actions of Ca2+ in rod photoreceptors, changes in cytoplasmic calcium concentration ([Ca2+]i) were opposed by manipulating the calcium fluxes across the outer segment membrane at different times during the response to a bright flash. 2. When the outer segment was superfused wit

9. Cux/CDP Homeoprotein Is a Component of NF-μNR and Represses the Immunoglobulin Heavy Chain Intronic Enhancer by Antagonizing the Bright Transcription Activator
Nuclear matrix attachment regions (MARs) flanking the immunoglobulin heavy chain intronic enhancer (Eμ) are the targets of the negative regulator, NF-μNR, found in non-B and early pre-B cells. Expression library screening with NF-μNR binding sites yielded a cDNA clone encoding an alternatively spliced form of the Cux/CDP homeodomain protein. Cux/CDP fulfi

10. Auxin-Dependent Cell Division and Cell Elongation. 1-Naphthaleneacetic Acid and 2,4-Dichlorophenoxyacetic Acid Activate Different Pathways1
During exponential phase, the tobacco (Nicotiana tabacum) cell line cv Virginia Bright Italia-0 divides axially to produce linear cell files of distinct polarity. This axial division is controlled by exogenous auxin. We used exponential tobacco cv Virginia Bright Italia-0 cells to dissect early auxin signaling, with cell division and cell elongation as physi

11. Expression of Early Light-Inducible Proteins in Flag Leaves of Field-Grown Barley.
Early light-inducible protein (ELIP) mRNA and protein levels were analyzed during maturation and senescence of barley (Hordeum vulgare L.) flag leaves under field conditions. The data clearly demonstrate that ELIP mRNA levels are related to the sunlight intensity before sample collection. Levels of mRNAs encoding both low and high molecular mass ELIPs fluctu

12. Amino Acid Levels in Carrot Cell Suspension Culture: No Correlation with Aspartate Kinase Isoenzyme Levels
Free and protein amino acids were analyzed during the growth cycle of a suspension culture of carrot (Daucus carota L.) in which there is a 10-fold increase in a lysine-sensitive isoenzyme of aspartate kinase during the early part of the growth cycle. There is little change in either total amino acids or in the amino acids derived from aspartate between 3 an
