1. Effect of Salicylic Acid, 2,4-D and 2i-P on the Production of Secondary Metabolites in Garcinia brasiliensis Mart. Callus
Abstract The aim of this work was to evaluate the effect of Salicylic acid, 2,4-D and 2-iP on the production of total phenolic and flavonoids as well in the levels of fukugetin and 7-epiclusianone in callus of Garcinia brasiliensis zygotic embryos. For this, Bacupari callus were exposed to different concentrations (0.0; 0.1; 1; 10; 100 µM) of Salicylic acid

2. How to shorten a plant breeding program? A case study with ornamental peppers
Abstract Plant breeding of ornamental peppers (Capsicum spp.) can be supported by biotechnological tools. The objective of this study was to evaluate the efficiency of an in vitro culture of immature zygotic embryos (IZE) to reduce the breeding cycle of ornamental pepper (C. annuum) in comparison to the conventional system. Three ornamental pepper genotypes

3. Optimum sample size in quantitative characteristics of seeds of polyembrynic mango
Abstract Determining the sample size in a scientific investigation is important because it gives reliability in the results together with the efficiency in the use of resources and optimization of time. Polyembryony is a characteristic that allows to obtaining clonal and zygotic plants in the same seed. In mango this characteristic is presented, however, th

4. Recurrent Somatic Embryogenesis and Plantlet Regeneration in Psidium guajava L.
A simple and efficient protocol for recurrent somatic embryogenesis and plant regeneration is one of the prerequisites for genetic improvement of guava. An efficient reproducible regeneration somatic embryogenesis protocol was developed in four genotypes of Psidium guajava L. using immature zygotic embryo as starter explant. Somatic embryogenesis induction w

5. In vitro germination of zygotic embryos of hybrid BRS Manicoré (E. guineensis X E. oleifera)
RESUMO O híbrido interespecífico BRS Manicoré (E. guineensis x E. oleifera), tem características agronômicas superiores. Porém, a taxa de germinação é baixa (30%) e o processo demorado quando as sementes são semeadas de forma convencional. O objetivo deste trabalho foi otimizar a germinação in vitro de embriões zigóticos desse híbrido comparan

6. Polyethylene glycol effects on somatic embryogenesis of papaya hybrid UENF/CALIMAN 01 seeds
Among commercial fruits, papaya (Carica papaya L.) is notably one of the most common ones around the world. The aim of the current study was to establish a somatic embryogenesis protocol for the hybrid UENF/CALIMAN 01, elucidating the effects of sucrose and 2,4-dichlorophenoxyacetic acid (2,4-D) on the induction of embryogenic cultures and the effect of poly

7. ESTRATÉGIAS PARA CONSERVAÇÃO DE ACESSOS DE COQUEIRO ANÃO DO BAG DA EMBRAPA TABULEIROS COSTEIROS. / CONSERVATION STRATEGIES FOR COCONUT DWARF ACCESSIONS OF EMBRAPA COASTAL TABLELANDS BAG.
A conservação do coqueiro tem sido alvo de estudos nos últimos anos por organizações de pesquisa pública e privada. Essas pesquisas têm se concentrado na obtenção de protocolos por crescimento lento ou criopreservação. O armazenamento, como meio de manutenção da viabilidade do pólen, é importante para a preservação da variabilidade genética

8. Embriogênese somática direta e criopreservação de embriões de Coffea arabica L. cv. Catuí Vermelho / Direct somatic embryogenesis and cryopreservation of embryos of Coffea arabica L. cv. Catuaí Vermelho
A espécie Coffea arábica é comumente propagada utilizando sementes ou estacas, entretanto a embriogênese somática apresenta-se como alternativa para sua propagação com alta taxa de multiplicação e maior uniformidade. A embriogênese possibilita ainda a conservação do material genético da espécie utilizando técnicas de criopreservação. Vários

9. Cloning and expression of embryogenesis-regulating genes in Araucaria angustifolia (Bert.) O. Kuntze (Brazilian Pine)
Angiosperm and gymnosperm plants evolved from a common ancestor about 300 million years ago. Apart from morphological and structural differences in embryogenesis and seed origin, a set of embryogenesis-regulating genes and the molecular mechanisms involved in embryo development seem to have been conserved alike in both taxa. Few studies have covered molecula

10. Proteomic evaluation of coffee zygotic embryos in two different stages of seed development.
Coffee seed development is accompanied by severe modifications in water soluble proteins, several of these being associated to a specific developmental stage. For this reason, a proteomic approach has been used to describe spatial-temporal proteome modifications in zygotic embryos at different stages of seed development. Embryos from Coffea arabica seeds wer

12. Comparative proteomical analysis of zygotic embryo and endosperm from coffea arabica seeds.
During coffee seed development, proteins are predominantly deposited in cotyledons and in the endosperm. Reserve proteins of the 11S family are the most abundant globulins in coffee seeds, acting as a nitrogen source during roasting and guaranteeing flavor and aroma. The aim of the present study was to compare the protein profiles of endosperm and zygotic em
