1. Induction and characterization of oil palm (Elaeis guineensis Jacq.) pro-embryogenic masses
RESUMO O dendezeiro é uma das oleoginosas mais importante economicamente, mas a expansão das plantações tem sido limitada pela disponibilidade de mudas, como a propagação convencional é através de sementes, que têm baixas taxas de germinação. Uma possível solução para produção em larga escala é por meio da embriogênese somática. O objetiv

2. Pro-embryogenic cell viability and cell suspension of Byrsonima intermedia A. Juss. / Viabilidade de CÃlulas PrÃ- EmbriogÃnicas e SuspesÃo Celular de Murici-Pequeno
The Murici-pequeno (Byrsonima intermedia A. Juss) is a fruitful medicinal species of Cerrado which presents difficulties to be propagated by conventional methods. This fact makes necessary the development of alternative methodologies of propagation for this species. In this work it was studied the in vitro seedlings growth according to residual effects of se

3. Embriogênese somática a partir de folhas imaturas e flores desenvolvidas in vitro de dendezeiro (Elaeis guineensis Jacq) / Somatic embryogenesis from immature leaves and flowers developed in vitro from oil palm (Elaeis guineensis Jacq)
The study aimed to establish an efficient protocol for somatic embryogenesis of the oil palm, especially all of cultivars explored in Brazil, as well as to acomplish the anatomical caracterization of the embryogenic process. For induction of somatic embryogenesis we used two explants types, leaves segments and female inflorescences, resulting in two experime

4. Calcium-Mediated Signaling during Sandalwood Somatic Embryogenesis. Role for Exogenous Calcium as Second Messenger1
The possible involvement of Ca2+-mediated signaling in the induction/regulation of somatic embryogenesis from pro-embryogenic cells of sandalwood (Santalum album) has been investigated. 45Ca2+-uptake studies and fura-2 fluorescence ratio photometry were used to measure changes in [Ca2+]cyt of pro-embryogenic cells in response to culture conditions conducive

5. Endogenous Nod-Factor-Like Signal Molecules Promote Early Somatic Embryo Development in Norway Spruce1
Embryogenic cultures of Norway spruce (Picea abies) are composed of pro-embryogenic masses (PEMs) and somatic embryos of various developmental stages. Auxin is important for PEM formation and proliferation. In this report we show that depletion of auxin blocks PEM development and causes large-scale cell death. Extracts of the media conditioned by embryogenic
