摘要:
Transformed plants that are capable of germinating in the presence of an externally applied chemical, nucleic acid sequences, vectors, and plasmids therefore, plant cells and plants transformed with such nucleic acid sequences, vectors and plasmids, a transient selectable marker system for use in the germination stages of plant development.
摘要:
A microorganism which is genetically modified so that it produces a first essential biomass precursor by metabolizing CO2 using a recombinant carbon fixation enzyme is disclosed. The microorganism produces a second biomass precursor by metabolizing an organic carbon source and not by metabolizing CO2. The microorganism does not use the organic carbon source for producing the first essential biomass precursor.
摘要:
The invention relates to an isolated, genetically modified microorganism, wherein compared to the wild type a) the idh1 and idp1 genes have been deleted or inactivated, and/or b) the sdh2 and sdh1 genes have been deleted or inactivated, and/or c) the PDC2 gene has been deleted or inactivated or is under the control of a promoter which can be suppressed or induced by exposure of the microorganism using an inductor substance, and/or d) one or more genes from the group consisting of ICL1, MLS1, ACS1 and MDH3 has been replaced or supplemented by a corresponding foreign gene or corresponding foreign genes from Crabtree-negative organisms, and to the uses thereof.
摘要:
The present invention relates to the isolation of DNA regulatory regions of the malate synthase 1 gene (MLS1) from the yeast, Pichia pastoris. The present invention further relates to the expression of heterologous proteins which have been introduced into a P. pastoris host cell and can be expressed under the regulation of the MLS1 5' regulatory promoter and MLS1 3'regulatory terminator regions. The MLS1 promoter is repressed in media containing glucose and derepressed under glucose starvation conditions or when acetate is present.
