1. Development of carpels and ovules in Dialypetalanthus fuscescens Kuhlm. (Rubiaceae): an enigmatic taxon
ABSTRACT Dialypetalanthus is a monospecific genus that occurs in the Amazon Basin of Brazil, Bolivia and Peru and occupies a controversial position among the Rubiaceae. We continue this taxonomic discussion with the overall aim of clarifying the systematic position of D. fuscescens within the Rubiaceae. To accomplish this, we analyzed the ontogeny of its gyn

2. Diferenciação floral, alternância de produção e uso de ácido giberélico em tangerineira 'Montenegrina' (Citrus deliciosa Tenore) / Flower bud differentiation, alternate bearing and application of gibberellic acid on ‘Montenegrina’ tangerine trees (Citrus deliciosa Tenore)
A alternância de produção é um problema na cultura da tangerina ‘Montenegrina’ (Citrus deliciosa Ten.). Objetivou-se testar o uso do ácido giberélico e épocas de aplicação na inibição floral e conseqüente diminuição da alternância. O experimento foi executado no período de abril de 2004 a agosto de 2005, no município de Eldorado do Sul,

3. Diferenciação floral, alternância de produção e aplicação de ácido giberélico em tangerineira 'Montenegrina' (Citrus deliciosa Tenore) / Flower bud differentiation, alternate bearing and application of gibberellic acid on "Montenegrina" (Citrus deliciosa Tenore) Tangerines
Após o descobrimento do ácido giberélico (AG3) em sementes de frutos, os pesquisadores começaram a aplicar ácido giberélico de maneira exógena em diferentes concentrações e épocas de aplicação com variados resultados. Um deles é a possibilidade de inibir a floração. A alternância de produção é um dos problemas mais importantes em algumas c

4. VFL, the Grapevine FLORICAULA/LEAFY Ortholog, Is Expressed in Meristematic Regions Independently of Their Fate1
The flowering process in grapevine (Vitis vinifera) takes place in buds and extends for two consecutive growing seasons. To understand the genetic and molecular mechanisms underlying this process, we have characterized grapevine bud development, cloned the grapevine FLORICAULA/LEAFY (FLO/LFY) ortholog, VFL, and analyzed its expression patterns during vegetat

5. Isolation and regulation of accumulation of a minor chromoplast-specific protein from cucumber corollas.
The differentiation of chloroplasts to chromoplasts in cucumber (Cucumis sativus L.) corollas parallels flower development. Chromoplast biogenesis involves chlorophyll degradation, carotenoid accumulation, and the appearance of a new set of proteins. To study factors involved in chromoplast biogenesis in floral tissues, a minor (in abundance) protein of abou

6. Isolation and Characterization of a Chromoplast-Specific Carotenoid-Associated Protein from Cucumis sativus Corollas.
The differentiation of chloroplasts to chromoplasts in corollas of cucumber (Cucumis sativus) is subject to developmental control. To study factors involved in the chloroplast-chromoplast conversion, a chromoplast-specific protein of 35 kD was isolated, and polyclonal antibodies were prepared against it. This protein was found to be a principal component of

7. Binding of Spermidine to a Unique Protein in Thin-Layer Tobacco Tissue Culture 1
The mechanism by which spermidine induces the appearance of floral buds in thin-layer tobacco (Nicotiana tabacum) tissue culture was studied by following the fate of the radioactive compound. [3H]Spermidine was taken up rapidly by the tissue, and after a brief lag, a portion was bound to trichloroacetic acid precipitable macromolecules. Such binding increase
