Abstract
The present invention provides polynucleotides and related polypeptides of the ZmERECTA gene family. The invention provides nucleic acid sequences for the Zm ERECTA genes. ZmERECTA is responsible for controlling plant growth, organ size and yield in crop plants.
Claims20
An isolated polynucleotide selected from the group consisting of:
- a. a polynucleotide having at least 70% sequence identity, as determined by the GAP algorithm under default parameters, to the full length sequence of a polynucleotide selected from the group consisting of SEQ ID NOS:
- 5, 7, 9, 11, 13, 15, 17, 19, 21, 23 and 25;
- wherein the polynucleotide encodes a polypeptide that functions as a modifier of organ size;
- b. a polynucleotide encoding a polypeptide selected from the group consisting of SEQ ID NOS:
- 6, 8, 10, 12, 14, 16, 18, 20, 22, 24 and 26 and
- c. a polynucleotide selected from the group consisting of SEQ ID NOS:
- 5, 7, 9, 11, 13, 15, 17, 19, 21, 23 and 25;
- and
- d. A polynucleotide which is complementary to the polynucleotide of (a), (b) or (c).

A product derived from the method of processing of transgenic plant tissues expressing an isolated polynucleotide encoding an ERECTA gene, the method comprising:
- a. transforming a plant cell with a recombinant expression cassette comprising a polynucleotide having at least 90% sequence identity to the full length sequence of a polynucleotide selected from the group consisting of SEQ ID NO:
- 5, 7, 9, 11, 13, 15, 17, 19, 21, 23 and 25, operably linked to a promoter;
- and
- b. culturing the transformed plant cell under plant cell growing conditions;
- wherein the growth in said transformed plant cell is modulated;
- c. growing the plant cell under plant-forming conditions to express the polynucleotide in the plant tissue;
- and
- d. processing the plant tissue to obtain a product.
