Isolated polynucleotides encoding a MAP65 polypeptide and methods of using same for increasing plant yield

摘要

Provided are methods of increasing yield, biomass, growth rate, vigor, and/or abiotic stress tolerance of a plant by expressing within the plant an exogenous polynucleotide comprising a nucleic acid sequence at least 80% identical to SEQ ID NO: 27 or 868; or an exogenous polynucleotide encoding a polypeptide at least 80% identical to SEQ ID NO: 132 (MAP65 from Arabidopsis).

1. A method of increasing a trait of a plant under non-stress growth conditions as compared to a non-transformed plant which is grown under the same growth conditions, the trait is selected from the group consisting of: rosette diameter, growth rate of plot coverage, growth rate of rosette diameter, growth rate of rosette area, and growth rate of leaf blade area, the method comprising:
(a) expressing within the plant an exogenous polynucleotide comprising a nucleic acid sequence encoding the polypeptide set forth in SEQ ID NO: 132, and (b) selecting plants resulting from step (a) for an increased rosette diameter, growth rate of plot coverage, growth rate of rosette diameter, growth rate of rosette area, and/or growth rate of leaf blade area under non-stress growth conditions as compared to a non-transformed plant which is grown under the same growth conditions, thereby increasing the trait of the plant under the non-stress growth conditions.
