1. Uso do suco das folhas da couve (Brassica oleracea var acephala), na estabilização da massa óssea pós-menopausa
Neste trabalho foi avaliado a utilização da folha da couve Brassica oleracea variedade acephala, pertencente à família Cruciferae, para estabilizar a massa óssea em 13 mulheres após a menopausa. As folhas da couve foram usadas após retirar a nervura principal e o peciolo, na forma de suco de uma folha ao dia, durante 24 meses. Foi realizado a cada sei

2. Primeiro registro de Lipaphis pseudobrassicae Davis (Hemiptera: Aphididae) e sua associação com insetos predadores, parasitóides e formigas em couve (Cruciferae) no Brasil
Este estudo descreve a fauna de insetos predadores, parasitóides e formigas associada a pulgões em couve (Brassica oleracea L. var. acephala D.C.), cultivada em sistema orgânico. O pulgão foi identificado como Lipaphis pseudobrassicae Davis, sendo este o primeiro registro da espécie atacando couve no Brasil. Parasitismo primário por Diaeretiella sp. e

3. Performance de um inseto oligófago em relação à idade da planta hospedeira
A performance de insetos folívoros monófagos e oligófagos deveria ser afetada negativamente pelo envelhecimento das suas plantas hospedeiras. Plutella xylostella L. (Lepidoptera: Yponomeutidae), uma especialista em Cruciferae, foi criada em laboratório com folhas destacadas de repolho (Brassica oleraceae var. capitata). Foram utilizadas a quarta folha ex

4. Studies of the floral biology and reproductive system of Brassica napus L.(Cruciferae)
Os estudos da biologia floral da Canola (cultivar CTC-4), objetivando o conhecimento do sistema reprodutivo e de suas estratégias reprodutivas foram realizados em Dourados-MS. B. napus é autopolinizada, apresentando no entanto, muitos recursos para realização de alogamia, como por exemplo pólen abundante, néctar e odor. As anteras menores foram respons

5. Evidence that the putative compatible solute 5-dimethylsulfoniopentanoate is an extraction artifact.
A novel gas chromatography-mass spectrometry method for analyzing sulfonium compounds as their S-demethylated silyl derivatives has clarified the origin of 5-dimethylsulfoniopentanoate. This compound, previously reported from flowers of Diplotaxis tenuifolia (L.) DC. (Cruciferae), is generated from glucoerucin during treatment with hot 6 N HCl. Glucoerucin i

6. The genome of Arabidopsis thaliana.
Arabidopsis thaliana is a small flowering plant that is a member of the family cruciferae. It has many characteristics--diploid genetics, rapid growth cycle, relatively low repetitive DNA content, and small genome size--that recommend it as the model for a plant genome project. The current status of the genetic and physical maps, as well as efforts to sequen

7. Distribution of Iron-Containing Superoxide Dismutase in Vascular Plants 12
Superoxide dismutases (EC 1.15.1.1) in vascular plants representing different evolutionary levels were characterized using polyacrylamide gel electrophoresis. The three forms of the enzyme were distinguished from each other based on the following criteria: a) the Cu-Zn enzyme is sensitive to cyanide wherease the Fe and Mn enzymes are not; and b) the Cu-Zn an

8. Small tandemly repeated DNA sequences of higher plants likely originate from a tRNA gene ancestor.
Several monomers (177 bp) of a tandemly arranged repetitive nuclear DNA sequence of Brassica oleracea have been cloned and sequenced. They share up to 95% homology between one another and up to 80% with other satellite DNA sequences of Cruciferae, suggesting a common ancestor. Both strands of these monomers show more than 50% homology with many tRNA genes; t

9. Effects of Aflatoxin on Seeding Growth and Ultrastructure in Plants
Nineteen plants belonging to 11 species of the cruciferae were studied to determine the effects of aflatoxin B1 on seed germination and seedling development. Germination was not inhibited in any test organism at a concentration of 100 μg of aflatoxin per ml of agar substrate. Inhibition of elongation of the hypocotyls and roots in the species studied varied

10. Photosynthetic Activity and Membrane Polypeptide Composition of Supergranal Chloroplasts from Plant Tissue Cultures Containing a Viruslike Particle 1
Tissue culture cells of Streptanthus tortuosus (Kell.) var. orbiculatus (Greene) Hall (Cruciferae), having a viruslike particle in their nucleoli, the STV cell line, contain “supergranal” chloroplasts. Freeze-fracture studies of chloroplasts of a control cell line, which lacks the viruslike particles, reveal two complementary faces similar to those obser

11. Biosynthesis and Immunolocalization of Lewis a-Containing N-Glycans in the Plant Cell1
We recently demonstrated the presence of a new asparagine-linked complex glycan on plant glycoproteins that harbors the Lewis a (Lea), or Galβ(1-3)[Fucα(1-4)]GlcNAc, epitope, which in mammalian cells plays an important role in cell-to-cell recognition. Here we show that the monoclonal antibody JIM 84, which is widely used as a Golgi marker in light and ele

12. Rapid evolution in plant chitinases: Molecular targets of selection in plant-pathogen coevolution
Many pathogen recognition genes, such as plant R-genes, undergo rapid adaptive evolution, providing evidence that these genes play a critical role in plant-pathogen coevolution. Surprisingly, whether rapid adaptive evolution also occurs in genes encoding other kinds of plant defense proteins is unknown. Unlike recognition proteins, plant chitinases attack pa
