1. What is the cause of low seed germination of Zanthoxylum rhoifolium Lam.?
ABSTRACT This study aimed to determine the main causes of low germination of Zanthoxylum rhoifolium Lam. (Rutaceae) seeds. Initially, the physical and physiological qualities were evaluated in seeds from four areas (lots) (Step I). Then, tests were performed (Step II) to determine physical dormancy (imbibition in water and methylene blue), physiological (ger

2. Genetic transformation of citrus with bacterio-opsin (bo), cecropin and gus genes. / Transformação genética de citros com os genes bacteriopsina (bO), cecropina e gus.
Application of modern biotechnology techniques, as genetic transformation, has helped breeding programs of perennial plant species. This technique is already successfully used in citrus in several countries, mostly to the production of more disease-tolerant plants. Present work had three objectives as it follows: 1. genetic transformation of Rangpur lime roo

3. Technical - scientific basis for the derivation of values-guides of quality of sediments for metals: field and laboratory experiments / Bases técnico - científicas para a derivação de valores-guias de qualidade de sedimentos para metais: experimentos de campo e laboratório
Este trabalho fez parte de um projeto FAPESP (Projeto QualiSed), onde foram envolvidas três instituições paulistas (UFSCar, UNICAMP, CETESB) e que teve como intuito levantar dados para a futura derivação Valores Guias de Qualidade de Sedimentos (VGQS) para metais e compostos orgânicos xenobióticos. O objetivo específico deste trabalho é o de gera

4. Modular sequence elements associated with origin regions in eukaryotic chromosomal DNA.
We have postulated that chromosomal replication origin regions in eukaryotes have in common clusters of certain modular sequence elements (Benbow, Zhao, and Larson, BioEssays 14, 661-670, 1992). In this study, computer analyses of DNA sequences from six origin regions showed that each contained one or more potential initiation regions consisting of a putativ

5. Division pattern of a round mutant of Escherichia coli.
A round mutant of Escherichia coli, when grown in Methocel medium, forms chains of cells and does not form tetrads. This implies that successive division planes of the round mutant are parallel rather than perpendicular. These results differ from a previous proposal that division planes in this round mutant are perpendicular to the prior division plane (W. D

6. RanBP2 associates with Ubc9p and a modified form of RanGAP1
Ran is a small GTPase required for nuclear transport in eukaryotic cells [Gorlich, D. & Mattaj, I. W. (1996) Science 271, 1513–1518]. Mutants in Ran also show defects in mRNA processing, cell cycle regulation, and other aspects of nuclear function [Rush, M. G., Drivas, G. & D’Eustachio, P. (1996) BioEssays 18, 103–112; Sazer, S. (1996) Trends Cell Biol
