Abstract:
Novel chimeric promoters which allow controlled transcription and/or expression of a nucleic acid sequence upon geminivirus infection, and the use of such recombinant promoters are provided. Furthermore, recombinant genes comprising such promoters and transgenic plant cells and plants comprising the chimeric promoters or recombinant genes are described.
Abstract:
Improved strains of Trichoderma spp. have been obtained as agents for the biological control of phytopathogenic fungi and nematodes, which strains are capable of overproducing a proteinase, by using a transformation process which involves the introduction of the gene prb1 of Trichoderma which codes for the proteinase PrB1 under the control of the appropriate elements of regulation of the expression, in multiple copies and in a stable way, whereby the control of the disease caused by pathogenic fungi or by netamodes is superior in the transgenic strain than in the wild strain used as receptor of the genetic information.
Abstract:
The present invention provides a method of producing a herbicide-resistant plant, which method entails delivering one or more herbicide resistance-conferring selectable marker genes into and expressing the same within the plastid of the plant, both in photosynthetic as well as non-photosynthetic cells. Nucleic acids for transformation and multicellular plants whose plastids have been transformed are also provided.
