A method of increasing yield, biomass and/or growth rate of a transgenic plant as compared to a control plant of the same species which is grown under the same growth conditions, comprising transforming the plant with an exogenous polynucleotide comprising a nucleic acid sequence encoding a polypeptide comprising an amino acid sequence having at least 95% sequence identity and conservative amino acid substitutions with respect to SEQ ID NO:
- 794, thereby increasing the yield, biomass and growth rate of the plant.
