An isolated DNA sequence capable of serving as regulatory element in a chimeric gene which can be used for the transformation of plants is disclosed. A chimeric gene containing the DNA sequence as a regulatory element for the transformation of plants is also disclosed. The gene comprises at least, in the direction of transcription, a promoter sequence, a transgene and a regulatory element, characterized in that the regulatory element comprises an intron from the noncoding 5' region of a plant histone gene, allowing the expression of the protein in the zones undergoing rapid growth. The production of transgenic plants is also disclosed.

Chimeric gene comprising intron from histone H3.3 gene

1. Chimeric gene containing several herbicide tolerance genes, plant cell and plant which are tolerant to several herbicides. 2. The plant is tolerant to several herbicides at the same time, in particular to the inhibitors of HPPD and to those of EPSPS and/or to the dihalohydroxybenzonitriles. 3. Use for removing weeds from plants with several herbicides.

The invention concerns a chimeric gene containing a DNA sequence coding for drosomycin, a vector containing the chimeric gene, a method for transforming plants and the resulting transformed plants. The drosomycin produced by the plants provides them with resistance to diseases, in particular of fungal origin.

An isolated DNA sequence capable of serving as regulatory element in a chimeric gene which can be used for the transformation of plants is disclosed. A chimeric gene for the transformation of plants is also disclosed. The gene comprises at least, in the direction of transcription, a promoter sequence, a transgene and a regulatory element, characterized in that the regulatory element consists of at least one intron 1 in the noncoding 5&prime; region of a plant histone gene allowing the expression of the protein in the zones and undergoing rapid growth. The production of transgenic plants is also disclosed.
