1. Traditional Eastern Spanish varieties of tomato
Despite the importance of traditional varieties of tomato (Solanum lycopersicum L.) as sources of variation in breeding programs and varieties targeted to high-price quality markets that value their exceptional organoleptic quality, little is known regarding the structure of these materials at the morphological level. In this study, a collection of 166 popul

2. Influência físico-hídrica nos atributos diagnósticos em latossolos do Distrito Federal / Water-physical influence on diagnostics attributes of distrito federal oxisols
Os Latossolos Vermelhos e os Latossolos Vermelho-Amarelos são os solos predominantes no Cerrado. A classe Latossolo Vermelho ocorre, sobretudo, nos topos das chapadas, enquanto a classe Latossolo Vermelho-Amarelo ocorre, principalmente, nas bordas de chapada e divisores, em superfícies planas, sempre adjacentes à classe dos Latossolos Vermelhos, e está a

3. Um estudo sobre os objetos cognatos e os adjetivos adverbiais no português do Brasil / A study about the cognate objects and adverbial adjectives in the Brazilian Portuguese
In this work, I analyze the phenomenon known as "the adverbial use of adjective" (or "adverbial adjectives"). Such phenomenon, common in Brazilian Portuguese (PB), occurs in sentences such as A Maria falou claro (cf. A Maria falou claramente) and raises a question about the categorial status of the modifier, since it presents adjective form, but behaves like

4. Insect juvenile hormone: from "status quo" to high society
Juvenile hormone (JH) exerts pleiotropic functions during insect life cycles. The regulation of JH biosynthesis by neuropeptides and biogenic amines, as well as the transport of JH by specific binding proteins is now well understood. In contrast, comprehending its mode of action on target organs is still hampered by the difficulties in isolating specific rec

5. Mechanisms of Derived Unitegmy among Impatiens Species
Morphological transitions associated with ovule diversification provide unique opportunities for studies of developmental evolution. Here, we investigate the underlying mechanisms of one such transition, reduction in integument number, which has occurred several times among diverse angiosperms. In particular, reduction in integument number occurred early in

6. Giant Vesicles under Oxidative Stress Induced by a Membrane-Anchored Photosensitizer
We have synthesized the amphiphile photosensitizer PE-porph consisting of a porphyrin bound to a lipid headgroup. We studied by optical microscopy the response to light irradiation of giant unilamellar vesicles of mixtures of unsaturated phosphatidylcholine lipids and PE-porph. In this configuration, singlet oxygen is produced at the bilayer surface by the a

7. Associations of methanotrophs with the roots and rhizomes of aquatic vegetation.
Results of an in vitro assay revealed that root-associated methane consumption was a common attribute of diverse emergent wetland macrophytes from a variety of habitats. Maximum potential uptake rates (Vmaxp) varied between about 1 and 10 micromol g (dry weight)-1 h-1, with no obvious correlation between rate and gross morphological characteristics of the pl

8. Gibberellins Repress Photomorphogenesis in Darkness1
Plants undergo two different developmental programs depending on whether they are growing in darkness (skotomorphogenesis) or in the presence of light (photomorphogenesis). It has been proposed that the latter is the default pathway followed by many plants after germination and before the seedling emerges from soil. The transition between the two pathways is

9. Prostaglandin E2 elicits a morphological change in cultured orbital fibroblasts from patients with Graves ophthalmopathy.
Fibroblasts derived from distinct anatomical regions appear to differ in regard to their behavior in culture. These differences may reflect functions of these cells in vivo that are tissue specific. Moreover, intrinsic differences in fibroblasts may underlie the site-specific connective tissue manifestations associated with systemic disease. We have demonstr
