13. Estresse osmótico e do retículo endoplasmático induzem morte celular programada de maneira dependente das proteínas NRPs / Osmotic- and ER-stress induce NRPs-dependent programed cell death
The identification of cell signaling pathways in response to different stresses and the interactions among these pathways have become major focus for understanding the molecular bases of plant cell-environment interactions. Recently, a novel integrative pathway between ER- and osmotic-stress has been described by our group. Among the target genes of the inte

14. A glycoprotein with anti-inflammatory properties secreted by an Aspergillus nidulans modified strain
Total RNA from lipopolysaccharide (LPS)-stimulated rat macrophages used to treat protoplasts from an Aspergillus nidulans strain originated the RT2 regenerated strain, whose culture supernatant showed anti-inflammatory activity in Wistar rats. The protein fraction presenting such anti-inflammatory activity was purified and biochemically identified. The scree

15. 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

16. Protoplasts production from Napier grass and pearl millet triploid hybrids. 2007. 44 p. Dissertation (Master Program in Genetics and Plant Breeding) â Universidade Federal de Lavras, Lavras, Minas Gerais, Brazil. / ObtenÃÃo de protoplastos de hÃbridos triplÃides entre o capim-elefante e milheto.
Buscando gerar maior variabilidade que resulte em avanÃos na obtenÃÃo de cultivares superiores os programas de melhoramento genÃtico do capim-elefante (2n = 4x = 28) realizam o cruzamento desta espÃcie com o milheto (2n = 2x = 14) Entretanto, o hÃbrido triplÃide (3x) resultante à infÃrtil impossibilitando sua utilizaÃÃo nesses A restauraÃÃo da f

18. Molecular and functional characterization of the NAC transfactor family from soybean (Glycine max) / Caracterização molecular e funcional de transfatores da família NAC de soja (Glycine max)
The identification of cell signaling pathways in response to different stresses has become a major focus for understanding the molecular bases of plantenvironment interactions. We have previously identified a set of soybean genes co-regulated by ER- and osmotic stresses, which possibly constitute a novel integrative pathway in plants. Among the identified ge

19. Fusão de protoplastos visando a reconstrução da laranja azeda / Protoplast fusion aiming the reconstruction of sour orange
The aim of this work was to apply the technique of chemical fusion of protoplasts, in order to develop interspecific somatic hybrids between mandarins (Citrus reticulata) and pummelos (Citrus grandis), in order to produce similar to sour orange (Citrus aurantium). The sources for protoplasts were embryogenic suspension cultures of Pagetangelo (C. reticulata

20. Beta -1,3 glucanases, proteases e quitinases : produção, purificação e aplicação. / Beta-1,3 glucanases, protease and chitinases : production, purification and application.
The aim of this work was to study the production, purification and application of b-1,3 glucanases, proteases and chitinases. The strain Cellulosimicrobium cellulans 191 was used to study the production of b-1,3 glucanases and chitinases and strains B26 and C. cellulans 191 for the production of proteases, using culture media containing different inductors.

21. Produção, purificação, clonagem e aplicação de enzimas líticas
Lytic enzymes such as beta-1,3 glucanases, proteases and chitinases are able to hydrolyse, respectively, beta-1,3 glucans, mannoproteins and chitin, as well as the cell walls of many yeast species. Lytic enzymes are useful in a great variety of applications including the preparation of protoplasts; the extraction of proteins, enzymes, pigments and functional

22. Genetic variability in regenerated Metarhizium flavoviride protoplasts
A formação e regeneração de protoplastos foram avaliadas em duas linhagens selvagens e duas linhagens mutantes para coloração de conídios em Metarhizium flavoviride. O cultivo em meio líquido seguido do tratamento do micélio com Novozym 234 na presença de KCl 0,7 M como estabilizador osmótico, resultou na produção de 5,05´10(6) a 1,15´10(7) pr

23. Seleção de linhagens de Saccharomyces cerevisiae potencializadas pelo fator Killer, H2S- e o carater floculante. / Improvement of a saccharomyces cerevisiae strain by the characters: "Killer" skills, flocculation capacity and lack in productinof H2S-.
Flocculative and "killer" skills and lack in production of H2S are desirable characteristics of the ethanolic fermentative yeasts. Seven selected strains of Saccharomyces cerevisiae with some of these characteristics were evaluated for confirmation of these habilities and their genetic characterization was undertaken by eletrophoretic kariotyping. The strain

The Amazon, one of areas with the highest biodiversity in the planet, has many plants with aromatic properties. Although most are still unknown. Among these, is the long pepper (Piper hispiridinervium C. DC.), a species that contains in leaves and young branches essential oil denominated safrole.
