Shine clade of transcription factors and their use
View Patent ↗The present invention relates to the field of transgenic plants with given phenotypes, especially plants with enhanced drought tolerance. Provided are SHINE proteins and nucleic acid sequences encoding these, which are useful in conferring these phenotypes to plants.
1. A transgenic monocotyledonous plant of the genus Oryza comprising a chimeric gene, integrated in its genome, which chimeric gene comprises a transcription regulatory sequence active in plant cells operably linked to a nucleic acid sequence encoding a SHN protein that comprises the sequence SEQ ID NO:15, wherein said plant possesses enhanced drought tolerance without modification of its epicuticular wax layer.
2. The plant according to claim 1 , wherein said SHN protein further comprises the sequence SEQ ID NO:16.
3. The plant according to claim 1 , wherein said transcription regulatory sequence is selected from the group consisting of: a constitutive promoter, an inducible promoter, a tissue-specific promoter and a developmentally-regulated promoter.
4. The plant according to claim 1 , wherein the sequence of the SHN protein is selected from the group consisting of SEQ ID NO:11, SEQ ID NO:12, SEQ ID NO:13, SEQ ID NO:14 and SEQ ID NO:24.
5. A seed or a fruit of a plant according to claim 1 , which seed or fruit comprises said chimeric gene.
6. A method of generating a transgenic plant according to claim 1 , comprising introducing and expressing in a monocotyledonous Oryza plant a nucleic acid sequence encoding said SHN protein, thereby generating said plant.
7. The transgenic monocotyledonous plant of claim 1 which is of the species Oryza sativa .
8. The method according to claim 6 wherein the plant is of the species Oryza sativa .
