摘要:
The present invention provides a chimeric gene useful to develop yeast strains for industrial fermentation at salt level conditions that reduce the fermentation efficiency. The invention also provides recombinant yeast strains for fermentation of second-generation substrates including cellulosic or lignocellulosic hydrolysates or of feedstocks with high salt levels. In addition, the invention relates to the use of such yeast strains for the production of second-generation biofuels.

摘要:
A composition-of-matter for mosquito control is provided. The composition comprises a cell which comprises an exogenous naked dsRNA which specifically down- regulates expression of a gene being endogenous to a mosquito or which specifically down-regulated expression of a gene being endogenous to a mosquito pathogen. Further provided is a composition-of-matter for mosquito control, comprising a cell comprising a nucleic acid larvicide. Also provided are methods of producing and using the compositions.
摘要:
A method of enhancing larvicide susceptibility in a mosquito larva is provided. The method comprising introducing into the mosquito larva an isolated nucleic acid agent comprising a nucleic acid sequence which specifically reduces the expression of at least one larvicide resistance gene product of the larva, thereby enhancing larvicide susceptibility in said mosquito larva.
摘要:
A method of enhancing resistance of a mosquito to a pathogen is disclosed. The method comprising administering to a mosquito an isolated nucleic acid agent comprising a nucleic acid sequence which specifically downregulates an expression of at least one mosquito or pathogen gene wherein a product of said mosquito or pathogen gene participates in infection and/or growth of the pathogen in the mosquito.
摘要:
A method of controlling a pathogenically infected mosquito is disclosed. The method comprising administering to a larva of a mosquito an isolated nucleic acid agent comprising a nucleic acid sequence which specifically downregulates an expression of at least one mosquito pathogen resistance gene product of the mosquito, wherein downregulation of the expression of the at least one mosquito pathogen resistance gene in the larvae renders an adult stage of the mosquito lethally susceptible to the pathogen, thereby controlling the pathogenically infected mosquito.

摘要:
A transgenic plant having enhanced photosynthesis is disclosed. The transgenic plant is transformed with a transgenic polynucleotide encoding a heterologous bicarbonate transporter. The bicarbonate transporter can be from an algae or a cyanobacterial species. The transgenic polynucleotide comprises a nucleic acid sequence encoding the bicarbonate transporter under the control of a functional plant promoter and optionally includes a chloroplast envelope targeting peptide heterologous to the bicarbonate transporter. Methods of making the transgenic plant and transgenic polynucleotide are disclosed.
