1. In vitro conservation of Poincianella pyramidalis (Tul.) L.P. Queiroz under minimal growth conditions
RESUMO Poincianella pyramidalis (Tul.) L.P. Queiroz, é uma espécie endêmica da Caatinga, se destaca pela importância nas atividades madeireira e medicinal. Este estudo teve como objetivo avaliar o efeito dos agentes osmóticos sacarose, sorbitol e manitol e o retardante de crescimento paclobutrazol (PBZ) na indução do crescimento mínimo in vitro de P.

2. Grafting height does not affect Fusarium wilt control or horticultural performance of Passiflora gibertii N.E.Br. rootstock
Abstract The influence of the grafting height (5, 10, 20 and 30 cm above the root collar) of P. edulis on P. gibertii was evaluated on the incidence of Fusarium wilt and horticultural performance. Plants of P. gibertii grafted on P. edulis and non-grafted plants of both species were also studied. In addition, histopathological studies were also performed on

3. Desempenho de bananeiras irrigadas em resposta a diferentes profundidades efetivas do solo na Chapada do Apodi - CE / Performance of banana in response to different irrigation effective soil depth in the Apodi Plateau - CE
The production of banana can be affected whether plants are cropped in sites with physical impedances, as those found in shallow soils. The aim of this research was to verify if irrigated banana plants performance is affected by effective soil depth, and for this purpose were evaluated both soil physical and chemical attributes, as well as plants nutritional

4. Raízes de aplicações de complexos 2-dimensionais em superfícies fechadas / Roots of maps from 2-dimensional complexes into closed surfaces
This text is the result of a detailed study of the topological root theory for maps from 2-dimensional CW complex into closed surfaces (compact and without boundary surfaces). Several approaches to the problems involved in this theory are presented, some of which are quite different with respect to the parameters of the classical theory

5. Methods for Growing Spirillum lipoferum and for Counting It in Pure Culture and in Association with Plants
Methods are described for growing Spirillum lipoferum in quantities sufficient to serve as inoculant in field trials of its associative N2-fixing ability with higher plants and as a source of cells for the preparation of nitrogenase, cytochromes, respiratory enzymes, etc. A heavy inoculum of S. lipoferum grown on NH4+ was transferred to a medium of minimal n

6. A Rhizobium meliloti lipopolysaccharide mutant altered in competitiveness for nodulation of alfalfa.
A transposon Tn5-induced mutant of Rhizobium meliloti Rm2011, designated Rm6963, showed a rough colony morphology on rich and minimal media and an altered lipopolysaccharide (LPS). Major differences from the wild-type LPS were observed in (i) hexose and 2-keto-3-deoxyoctonate elution profiles of crude phenol extracts chromatographed in Sepharose CL-4B, (ii)

7. Cell proliferation and hair tip growth in the Arabidopsis root are under mechanistically different forms of redox control
We provide evidence that the tripeptide thiol glutathione (GSH) participates in the regulation of cell division in the apical meristem of Arabidopsis roots. Exogenous application of micromolar concentrations of GSH raised the number of meristematic cells undergoing mitosis, while depletion of GSH had the opposite effect. A role for endogenous GSH in the cont

8. Improved Soybean Root Association of N-Starved Bradyrhizobium japonicum
In this study, we addressed the effects of N limitation in Bradyrhizobium japonicum for its association with soybean roots. The wild-type strain LP 3001 grew for six generations with a growth rate of 1.2 day−1 in a minimal medium with 28 mM mannitol as the carbon source and with the N source [(NH4)2SO4] limited to only 20 μM. Under these conditions, the g
