1. Botanical and genetic characters of Erythrina × neillii cultivated in Egypt
Abstract Erythrina × neillii Mabberley & Lorence, Fabaceae, is a sterile hybrid between E. herbacea L. and E. humeana Spreng. Nothing was traced about its genetic, macro and micromorphology. Therefore, it was deemed of interest to study its botanical characters, in addition to the DNA fingerprint to help in the identification of the plant. The anatomical ch

2. O espessamento primário no sistema caulinar e a continuidade entre esses tecidos nos órgãos vegetativos de Zingiberaceae e Costaceae: enfoque nos tecidos endoderme e periciclo / The primary thickening in stem system and the continuity between tissues in vegetative organs from Zingiberaceae e Costaceae: approach in tissues endodermis and pericycle
Essa dissertação foi subdivida em cinco capítulos que, apesar de relacionados entre, podem ser lidos e compreendidos de forma independente. O primeiro capítulo trata de um breve histórico sobre o espessamento primário em caules de monocotiledôneas. Seu principal objetivo é deixar evidente para o leitor a problemática referente tanto à nomenclatura

3. Morfoanatomia e composição mineral de raízes de duas espécies de restinga submetidas ao excesso de ferro / Morphoanatomy and mineral composition of roots from two species of restinga submitted to iron excess
In the south coast of Espírito Santo, Brazil, the restinga has received in the last years, an additional increment of iron, due to activities of iron ore industries. It was objectified to characterize the roots structure of the native restinga species, Ipomoea pescaprae L. (Convolvulaceae) and Canavalia rosea DC. (Fabaceae), with the iron plaque development

4. Micropropagação e anatomia foliar de Canela-de-Ema (Vellozia flavicans Mart. ex Schult f.-Velloziaceae) em diferentes condições ambientais
Canela-de-ema (Vellozia flavicans Mart. ex Schult. f.) is a shrub native of Brazilian Cerrado and presents great potential ornamental. Limitations in the conventional cultivation and the slow growth of the plant justify the use of techniques of tissue culture to propagate the species. The objective of this study was to establish a protocol for micropropagati

5. 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

6. ADVENTITIOUS ROOTING OF CUTTINGS OF Sebastiania schottiana Müll. Arg. / ENRAIZAMENTO ADVENTÍCIO DE ESTACAS DE Sebastiania schottiana Müll. Arg.
The aim of this work was to verify the cuttings rooting potential of Sebastiana schottiana as mechanism of vegetative propagation. Cuttings were collected next to the edges of Soturno River, Faxinal de Soturno County, situated in the regions of Plateaus and central depression of the Rio Grande Do Sul State, Brazil. Plants donors of cuttings were 5 years of a

7. Caracterização anatômica de FILGUEIRASIA ARENICOLA (McClure) Guala (POACEAE: BAMBUSOIDEAE: ARTHROSTYLIDIINAE)
The genus Filgueirasia (McClure) Guala belongs to the sub-family Bambusoideae is composed of two species, Filgueirasia arenicola (McClure) Guala, and Filgueirasia cannavieira (Álvaro da Silveira) Guala, which are endemic of Brazilian Cerrado. The objective of this study is to characterize morpho-anatomically the vegetative organs of three populations of F.

10. Anatomia dos órgãos vegetativos de Ianthopappus corymbosus Roque & Hind (Asteraceae-Mutisieae)
Estudo sobre a anatomia dos órgãos vegetativos de I. corymbosus foi realizado para servir como base na comparação com o gênero Richterago, o qual incluia anteriormente a espécie em questão. Os caracteres anatômicos de I. corymbosus que podem ser utilizados para a exclusão da espécie do gênero Richterago são: a organização das células epiteliai

11. Auxin-Mediated Cell Cycle Activation during Early Lateral Root Initiation
Lateral root formation can be divided into two major phases: pericycle activation and meristem establishment. In Arabidopsis, the first lateral root initiation event is spatially and temporally asynchronous and involves a limited number of cells in the xylem pericycle. To study the molecular regulation during pericycle activation, we developed a lateral root

12. Pericycle Cell Proliferation and Lateral Root Initiation in Arabidopsis1
In contrast with other cells generated by the root apical meristem in Arabidopsis, pericycle cells adjacent to the protoxylem poles of the vascular cylinder continue to cycle without interruption during passage through the elongation and differentiation zones. However, only some of the dividing pericycle cells are committed to the asymmetric, formative
