1. In vitro adventitious shoot regeneration from leaf explants of some apricot cultivars
RESUMO O damasco é considerado uma das frutas mais valiosas comercialmente. A propagação in vitro de damasco é muito importante para a multiplicação de cultivares com características desejáveis, saudáveis e livres de vírus. O fator limitante para a propagação por métodos convencionais é a baixa frequência na multiplicação. Nesse contexto, o

2. Insect galls of restinga areas of Ilha da Marambaia, Rio de Janeiro, Brazil
Insect galls of restinga areas of Ilha da Marambaia, Rio de Janeiro, Brazil. This study carried out an insect gall inventory in restinga areas of Ilha da Marambaia, in the municipality of Mangaratiba, Rio de Janeiro, Brazil. Sampling was carried out monthly from April 2010 to March 2011 along the full extension of seven beaches. A total number of 147 gall mo

3. Efficient Regeneration of Eucalyptus urophylla x Eucalyptus grandis from Stem Segment
The aim of the present study was to establish an efficient regeneration system for the hybrid E. urophylla x E. grandis by means of organogenesis. Stem segments from seedlings were used as explants and cultured in a modified Murashige and Skoog medium (MS), supplemented with 13.2 µM N-phenyl-N'-[6-(2-chlorobenzothiazol)-yl] urea (PBU) and 0.285 µM indole-3

4. Anatomical studies of in vitro organogenesis induced in leaf-derived explants of passionfruit.
With the aim os studying the organogenesis in vitro in Passiflora edulis Sims f. flavicarpa Deg., the passionfruit, leaf-derived explants were cultured on media containing NAA or BAP and incubated either in continuous darkness or in light. The histological events leading to de novo organ formation were evaluated. Darkness induces rhizogenesis in the presence

5. Desenvolvimento in vitro e imunolocalização de 5-metilcitosina em raízes tuberizadas e não-tuberizadas de Viguiera arenaria Baker (Asteraceae) / In vitro development and immunolocalization of 5-methylcytosine in tuberized and nontuberized roots of Viguiera arenaria Baker (Asteraceae)
Viguiera arenaria Baker is an herbaceous Asteraceae from Cerrado presenting alternate phyllotaxis, capitulum inflorescence and tuberized roots. Although phytochemical analyses have found substances with biological activities of therapeutic interest, little is known about the biology of the plant. In this study, we sought to contribute to the knowledge of asp

6. Transformação genética de abobrinha-de-moita e melancia para resistência ao Papaya ringspot virus - type Watermelon e ao Zucchini yellow mosaic virus / Genetic transformation of zucchini squash and watermelon for resistance to Papaya ringspot virus - type W and Zucchini yellow mosaic virus
Diseases caused by the potyviruses Papaya ringspot virus - type Watermelon (PRSV-W) and Zucchini yellow mosaic virus (ZYMV) significantly reduce the yield and fruit quality of zucchini squash (Cucurbita pepo), watermelon (Citrullus lanatus), as well as other cucurbit crops in Brazil. The purpose of this work was to obtain zucchini squash and watermelon trans

7. Glutamine and antioxidant metabolism during adventitious organogenesis of Ananas comosus leaves / Glutamina e metabolismo antioxidante durante a organogênese adventícia em folhas de Ananas comosus
A positive influence of glutamine on organogenesis of in vitro cultured plant tissues has been demonstrated by several studies. It is well known that the endogenous synthesis of phytohormones can be influenced by nitrogen sources, although it is not completely established in which way glutamine acts in this process. The addition of this amino acid to the cul

8. The role of the endodermis and pericycle in the formation of primary tissues in Commelinaceae (Monocotyledons) / Estudos em Commelinaceae (Monocotiledôneas): o papel da endoderme e do periciclo na formação do corpo primário
The aim of this work is to show the meristematic activity of the endodermis in roots of five species of Commelinaceae (Commelina erecta, Floscopa glabrata, Dichorisandra tyrsiflora, Tradescantia spathacea e T. zebrina). In all species was observed the initial endodermis suffered several periclinal divisions, originating the radiate layers of the cortex cells

9. In vitro organogenesis and genetic transformation of the Volkamer lemon (Citrus volkameriana) and sour orange (Citrus aurantium) / Organogênese in vitro e transformação genética de limão Volkameriano(Citrus volkameriana) e laranja azeda (Citrus aurantium)
Genetic transformation permits the introduction of agronomically important genes in plant genome and can be utilized in order to produce disease resistant plants. However for the recovery of transgenic plants is required to establish an efficient in vitro plant regeneration protocol. In this work the aim was to study an in vitro organogenesis and the genetic

10. Estudo morfofisiologico do desenvolvimento das especies Galianthe grandifolia E. L. Cabral (Rubiaceae) e Campulocliniun chlorolepis Baker (Asteraceae) submetidas a diferentes concentrações de cadmio / Morphophysiological development of Galianthe grandifolia E. L. Cabral (Rubiaceae) and Campulocliniun chlorolepis Baker (Asteraceae) subjected to different cadmium concentrations
The accumulation of toxic metals in the soil brings forth great environmental damages, especially cadmium, due to its high toxicity and cumulative effects on the organisms in general. There are a few studies regarding heavy metals and Cerrado native species. The aim of this work was to assess the behavior of two Cerrado species cultivated in the greenhouse:

Osbeck) e laranja Valência(Citrus sinensis L. Osbeck) com o gene da replicase do Marafivirus
Embora desfrute de inegável importância econômica, os citros estão sujeitos a muitos problemas sanitários sendo alguns, limitantes para o cultivo como é o caso das doenças causadas por vírus. A morte súbita dos citros é uma doença relacionada à combinação copa/ porta-enxerto e manifesta sintomas na região da enxertia sobre porta-enxertos intol
