Abstract
The present invention relates to nucleic acid sequences which have a transcriptional promoter activity preferentially in the phloem of plants under conditions of stress, or in the roots, to derived sequences, to constructs containing such sequences, and also to cells transformed with said constructs and to transgenic plants. The present invention makes it possible to place any transgene under the transcriptional control of a promoter, the activity of which is tissue-specific, organ-specific and/or inducible by environmental factors, such as biotic or abiotic stresses.
Claims23
An isolated nucleic acid sequence comprising the sequence SEQ ID NO:1, wherein:
- said nucleic acid sequence has transcriptional promoter activity.
A transgenic plant comprising in its genome a nucleic acid sequence comprising SEQ ID NO:1;
- wherein
- said sequence has transcriptional promoter activity;
- and
- said sequence is in functional association with a heterologous coding sequence expressing said coding sequence in a specific manner in the roots.
A transgenic plant comprising in its genome a nucleic acid sequence comprising all or a portion of SEQ ID NO:
- 1, wherein:
- said sequence has transcriptional promoter activity;
- and
- said sequence is in functional association with a heterologous coding sequence expressing said coding sequence in a specific manner in the phloem.
