Methods are described for producing a plant with altered seed yield comprising transformation of a plant with a genetic construct including a polynucleotide encoding of a polypeptide with the amino acid sequence of SEQ ID NO: 1 or a variant or fragment thereof. Also provided by the disclosed methods are isolated polypeptides, polynucleotides, constructs and vectors useful for producing a plant with altered seed yield. The methods also provide plant cells and plants transformed to contain and express the polypeptides, polynucleotides and constructs. Plants produced by the disclosed methods are further provided.

Polynucleotides and methods for the improvement of plants

The invention provides the isolated promoter polynucleotide sequence of SEQ ID NO: 1 from perennial ryegrass (L.), and fragments and variants thereof. The invention also provides constructs, plant cells and plant genetically modified to contain the promoter polynucleotide. The invention also provides methods for producing plants with altered gene expression and traits via genetic transformation of plants with the promoter polynucleotide.

Control of gene expression in plants

The invention provides methods, polynucleotides and polypeptides useful for producing or selecting plants with increased tolerance to at least one environmental stress selected from drought, cold, freezing, heat and salinity. The invention also provides constructs, cells, plant cells and plants comprising the polynucleotides of the invention. The invention also provides plants produced by the methods of the invention. The invention also provides groups of plants selected by the methods of the invention.

Methods and compositions for the improvement of plant tolerance to environmental stresses

The invention provides the isolated promoter polynucleotide sequence of SEQ ID NO:1, and fragments and variants thereof. The invention also provides constructs, plant cells and plants genetically modified to contain the promoter polynucleotide. The invention also provides methods for producing plants with altered gene expression and traits via genetic transformation of plants with the promoter polynucleotides.

Gene expression control in plants

The invention provides methods and compositions for producing plant with altered biomass, the methods comprising the step of altering the expression and/or activity of the polypeptide comprising the sequence of SEQ ID NO:1, or a variant thereof, in a plant cell or plant. The invention also provides a polypeptide comprising the sequence of SEQ ID NO:1, and fragments of variants thereof the sequence. The invention also provides polynucleotides encoding such polypeptide sequences. The invention also provides constructs, cells and plants comprising such polynucleotides.

Polynucleotides and methods for improving plants

The invention provides compositions and methods useful for producing plant cells or plants with altered tolerance to at least one environmental stress selected from drought, cold, freezing, heat and salinity.

Compositions and methods for the improvement of plants

The invention provides compositions and methods useful for producing a plant cell or plant with altered tolerance to drought by transformation of the plant cell or plant with a genetic construct encoding a polypeptide with at least 90% identity to the amino acid sequence of SEQ ID NO:4.
