Plant traits conferred by isolated polynucleotides and polypeptides

A method of increasing at least one trait selected from the group consisting of biomass, plot coverage, rosette area, rosette diameter photosynthetic capacity, nitrogen use efficiency, and tolerance to nitrogen deficiency stress of a plant as compared to a control plant, comprising over-expressing within the plant a polypeptide comprising an amino acid sequence selected from the group consisting of SEQ ID NOs:

• 15889, 17881 and 17882 as compared to a control plant of the same species which is grown under the same growth conditions, thereby increasing the at least one trait selected from biomass, plot coverage, rosette area, rosette diameter, photosynthetic capacity, nitrogen use efficiency, and tolerance to nitrogen deficiency of the plant as compared to the control plant.

A method of producing a crop, comprising growing a crop plant over-expressing a polypeptide comprising an amino acid sequence at least 95% identical to the amino acid sequence set forth by SEQ ID NO:

• 15889 as compared to a control plant of the same species which is grown under the same growth conditions, wherein said amino acid sequence comprises the domains depicted by InterPro numbers IPR032675 and IPR001810, wherein the crop plant is derived from plants which have been subjected to genome editing for over-expressing said polypeptide and/or which have been transformed with an exogenous polynucleotide encoding said polypeptide and which have been selected for at least one trait selected from the group consisting of increased biomass, increased plot coverage, increased rosette area, increased rosette diameter, increased photosynthetic capacity, increased nitrogen use efficiency, and/or increased tolerance to nitrogen deficiency stress as compared to a control plant of the same species which is grown under the same growth conditions, and the crop plant has the at least one trait selected from increased biomass, increased plot coverage, increased rosette area, increased rosette diameter, increased photosynthetic capacity, increased nitrogen use efficiency, and/or increased tolerance to nitrogen deficiency-stress, thereby producing the crop.

A nucleic acid construct comprising an isolated polynucleotide comprising a nucleic acid sequence encoding a polypeptide which comprises an amino acid sequence at least 95% identical to the amino acid sequence set forth by SEQ ID NO:

• 15889, and a heterologous promoter for directing transcription of said nucleic acid sequence in a host cell, wherein said amino acid sequence comprises the domains depicted by InterPro numbers IPR032675 and IPR001810, and wherein said amino acid sequence is capable of increasing at least one trait selected from the group consisting of biomass, plot coverage, rosette area, rosette diameter, photosynthetic capacity, nitrogen use efficiency, and/or tolerance to nitrogen deficiency stress of a plant.

A nucleic acid construct comprising an isolated polynucleotide comprising a nucleic acid sequence encoding a polypeptide which comprises an amino acid sequence selected from the group consisting of SEQ ID NOs:

• 15889, 17881 and 17882, and a heterologous promoter for directing transcription of said nucleic acid sequence in a host cell.
