METHOD OF REGULATION OF BIOMASS PRODUCTION IN PLANTS, DNA SEQUENCES AND METHOD OF PREPARATION THEREOF

摘要

The invention relates to a method of regulation of biomass production in plants, wherein the gene CKI1 or a homologue or an orthologue thereof is identified in the plant and the expression of the gene CKI1 or a homologue or an orthologue thereof or the activity of the gene product is modified. The identification of the homologue or the orthologue of the gene CKI1 in the plant species comprises the following steps: i) identification of the nucleotide sequence homology or amino acid sequence homology, ii) proving the histidine kinase activity of the gene product of the identified gene, iii) identification of the expression in vascular tissues of the respective plant species. Modification of the expression of the gene includes increasing or decreasing of the expression.
