1. [PROVISIONAL] Identification of histone methylation modifiers and their expression patterns during somatic embryogenesis in Hevea brasiliensis
Abstract Histone methylation plays a crucial role in various biological processes including from heterochromatin formation to transcriptional regulation. Currently, no information is available regarding histone methylation modifiers in the important rubber-producing plant Hevea brasiliensis. Here, we identified 47 histone methyltransferase (HMT) genes and 25

2. Efficient In Vitro Somatic Embryogenesis and Plant Regeneration from Mature and Immature Embryos of Wheat ( Triticum aestivum L.)
ABSTRACT An efficient regeneration system is a pre-requisite for the application of genetic transformation and functional genomics study of important plants. In this study, the effect of different factors (plant growth regulators, casein hydrolysate, aspartic acid and ascorbic acid) on in vitro embryogenesis and regeneration of Arta, Bahar and Zagros cultiva

3. Large-scale, high-efficiency production of coffee somatic embryos
Abstract The study aims to compare the efficiency of previously used liquid media for coffee, evaluating NAA concentrations in liquid medium and proline in semi-solid medium in the regeneration of somatic embryos and asses concentrations of BA and IAA in the maturation of embryos in temporary immersion bioreactors. For the regeneration of globular embryos fr

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. Somatic embryogenesis in Acrocomia aculeata Jacq. (Lodd.) ex Mart using the thin cell layer technique
Considering the necessity of Acrocomia aculeata propagation for large-scale production, the aim of this study was to establish a somatic embryogenesis protocol using the thin cell layer (TCL) technique. Aerial parts of in vitro plants were transversally cut at the base into eight TCLs and placed in a culture medium for callus induction. The induction medium

6. Somatic embryogenesis and plant regeneration in Wedelia calendulacea Less. an endangered medicinal plant
In this work, plant regeneration via somatic embryogenesis was achieved from leaf and internode derived callus of Wedelia calendulacea, an endangered medicinal plant. Primary callus was induced by culturing leaf disc and internode explant on Murashige and Skoog medium supplemented with 2.0 mg L-1 of 2,4-D under light condition. Transfer of embryogenic callus

7. Compounds used to produce cloned animals are genotoxic and mutagenic in mammalian assays in vitro and in vivo
The compounds 6-dimethylaminopurine and cycloheximide promote the successful production of cloned mammals and have been used in the development of embryos produced by somatic cell nuclear transfer. This study investigated the effects of 6-dimethylaminopurine and cycloheximide in vitro, using the thiazolyl blue tetrazolium bromide colorimetric assay to assess

8. 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

9. 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

10. Effect of picloram, additives and plant growth regulators on somatic embryogenesis of Phyla nodiflora (L.) Greene
The present study describes the plant regeneration via somatic embryogenesis in suspension culture derived from the leaf and stem explants of Phyla nodiflora. The medium type, plant growth regulators, complex extract (coconut milk and malt extract) and anti-oxidant (activated charcoal, ascorbic acid, Polyvinylpyrrolidone and citric acid) markedly influenced

12. Transferência nuclear de células somáticas (TNCS) em ruminantes: aspectos moleculares e produção de embriões. / Somatic cell nuclear transfer (SCNT) in ruminants: the molecular and embryo production.
O sucesso da produção de animais clones por Transferência Nuclear de Células Somáticas (TNCS) envolve múltiplas etapas e cada uma destas pode influenciar a eficiência final da técnica. Assim, para investigar fatores relacionados à TNCS em ruminantes, esse trabalho teve como objetivos: (i) avaliar o efeito de um protocolo alternativo de estimulação
