1. Pre-isolation, isolation and regeneration protoplasts from leaf mesophyll of in vivo Malus domestica ‘Anna’ cv.
Resumo Protoplastos in vivo do mesofilo foliar da cultivar de macieira “Anna” foram isolados de folhas com 15 dias de idade através de plasmólise em meios contendo manitol a 90 g L-1, por meia hora e em seguida a 130 g L-1, pelo mesmo tempo. Anteriormente ao isolamento dos protoplastos foi realizado um pré tratamento com mistura enzimática contendo

2. Antagonistic endophytic bacteria associated with nodules of soybean (Glycine max L.) and plant growth-promoting properties
Abstract A total of 276 endophytic bacteria were isolated from the root nodules of soybean (Glycine max L.) grown in 14 sites in Henan Province, China. The inhibitory activity of these bacteria against pathogenic fungus Phytophthora sojae 01 was screened in vitro. Six strains with more than 63% inhibitory activities were further characterized through optical

3. Yeast extract elicitation increases vinblastine and vincristine yield in protoplast derived tissues and plantlets in Catharanthus roseus
Abstract Catharanthus roseus (L.) G. Don, Apocynaceae, is an immensely important medicinal plant, produces a variety of anticancerous compounds. The yield of two most investigated alkaloids vinblastine and vincristine is unfortunately very low. A vast array of technologies including elicitation have recently been used to enrich Catharanthus alkaloid in cultu

4. How does the nectar of stomata-free nectaries cross the cuticle?
ABSTRACT In many glandular structures, departure from the cell is only one step in the process of exudate release to the plant surface. Here the set of events that lead nectar to the external environment is presented and discussed mainly for stomata-free nectaries. After being synthesized, the nectar or some of its component needs to be released to the envir

6. Plant regeneration from protoplast of brazilian citrus cultivars.
O objetivo deste trabalho foi regenerar plantas a partir de protoplastos de cultivares brasileiras de citros, após isolamento, fusão e cultura. Protoplastos foram isolados a partir de células embriogênicas em suspensão e de mesófilo foliar de plântulas germinadas in vitro. A solução enzimática para o isolamento de protoplastos foi composta de manit

7. Construction of killer industrial yeast Saccharomyces cerevisiae HAU-1 and its fermentation performance
Saccharomyces cerevisiae HAU-1, a time tested industrial yeast possesses most of the desirable fermentation characteristics like fast growth and fermentation rate, osmotolerance, high ethanol tolerance, ability to ferment molasses, and to ferment at elevated temperatures etc. However, this yeast was found to be sensitive against the killer strains of Sacchar

8. Isolation and fusion of protoplasts from the phytopathogenic fungus Sclerotium rolfsii (Sacc.)
Sclerotium rolfsii (Sacc.) is a serious plant pathogenic fungus and lacks perfect (basidial) stage in production. Protoplast fusion technology was employed to reconstruct fusants from this fungus. Two strains designated as A and R were used. Maximum protoplast yields of 3.8x10(5) /g mycelia and 2.8x10(5) /g mycelia were formed in strains A and R respectively

9. Isolation, protoplast culture and regeneration of sweet orange (Citrus sinensis L. Osbeck) / Isolamento, cultura de protoplastos e regeneração de plantas de laranja doce (Citrus sinensis L. Osbeck)
A regeneração de plantas, por organogênese ou embriogênese somática, a partir do cultivo de células e tecidos vegetais in vitro é a base para a utilização da biotecnologia no melhoramento. Realizaram-se estudos com cinco cultivares de laranja doce (Citrus sinensis L. Osbeck), Pêra, Natal, Lima Verde, Hamlin e Westin. Este trabalho objetivou a avali

10. 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

11. Identificação de genes expressos durante a fase pré-simbiótica da associação ectomicorrízica entre Hydnangium sp. e Eucalyptus grandis e transformação de fungos ectomicorrízicos / Identification of genes expressed during the pre-symbiotic interaction in the Hydnangium sp.-Eucalyptus grandis ectomycorrhizal association and transformation of ectomycorrhizal fungi
Gene expression in the ectomycorrhizal fungus Hydnangium sp. during the pre-symbiotic interaction was evaluated using an in vitro mycorrhization technique aiming at constructing a suppressive subtractive cDNA library. The fungus was cultivated in the presence of Eucalyptus grandis roots, with no direct physical contact between both organisms. Genes that code

12. EmbriogÃnese somÃtica e isolamento de protoplastos de pequizeiro / Somatic embryogenesis and protoplast isolation of Caryocar brasiliense CAMB.
The Caryocar brasiliense is one of the native fruit species from Cerrado with higher economical, ecological and social importance. In the last decades, large land extensions in the â Cerrado â has been used for agricultural system. This fact associated with a natural low regeneration rate has caused the reduction in natural populations of the species. Base
