1. A method of increasing the tolerance of a corn plant to water deficit, comprising overexpressing in said corn plant a R2R3-MYB subfamily 4 transcription factor, having at least 95% identity with the sequence SEQ ID NO: 1, wherein said R2R3-MYB subfamily 4 transcription factor is derived from a monocotyledonous plant, and comprises the conserved amino acids located at positions 1-9, 11-13, 15-22, 24-25, 27, 30-41, 43-70, 74-75, 77-78, 80-83, 85-93, 95-111, 113-116, 120-127, 138, 140-141, 197, 202-212, 214, 234, 239, 242, 252, 254-255, 261-263, 267-271 and 274-275 of said sequence SEQ ID NO: 1 when it is aligned with said sequence SEQ ID NO: 1 and said overexpression is obtained by:
genetic transformation of said corn plant with one or more copies of a polynucleotide encoding said R2R3-MYB subfamily 4 transcription factor, combined with cis regulatory sequences for its expression. |
