Maize erecta genes to improve Plant Growth, transpiration efficiency and Drought Tolerance in crop plants.

摘要

Polynucleotides and polypeptides associated with the zmerecta Gene Family. Nucleic Acid sequences of the genes zmerecta. Zmerecta is responsible for the control of Plant Growth, the size of the Organs and yield in crop plants.Claim 1: an isolated polynucleotide wherein selected from the group consisting of: (a) a polynucleotide that has at least 70% Sequence identity with the algorithm, a certain Gap with the default parameters, The Complete sequence of a polynucleotide Selection The ado group consisting in SEQ ID no: 5, 7, 9, 11, 13, 15, 17, 19, 21,23 and 25; where the polynucleotide encodes a polypeptide that serves as a modifier, the size of the organs; (b) a polynucleotide that encodes a polypeptide selected from the group consisting of SEQ ID no: 6, 8, 10, 12, 14, 16, 18, 20, 22, 24 and 26, and (c) a polynucleotide selected d The group is in SEQ ID no: 5, 7, 9, 11, 13, 15, 17, 19, 21,23 and 25; (d) a polynucleotide which is complementary with the polynucleotide of (a), (b) or (c). Claim 3: a host Cell which comprises the expression cassette of claim 2. Claim 3: a transgenic Plant which comprises the recombinant expression cassette of claim 2. Claim: 8.A transgenic Seed characterized because it comes from the transgenic plant of claim 4.Claim 7: a method to modulate the size of organs in PlantsCharacterized in that it comprises: (a) introducing into a Plant Cell, a recombinant expression cassette comprising the polynucleotide operably linked to a promoter of claim 1; and (b) cultivate The Plant under appropriate conditions for cultivating plant cells, where they modulate The size of the organs in the Plant Cell.
