Isolated transcription factors of Carica papaya and its application to obtain tolerant plants at extreme temperatures.

摘要

This invention refers to four isolated cprap2 genes of Carica papaya, identified as cprap2.4a, cprap2.4b, cprap2.1, cprap2.10 and consisting of SEQ sequences. ID No: 1, SEQ. ID No: 2, SEQ. ID in: 3 and SEQ. ID No: 4, as well as methods of genetic transformation for the over -expression of said genes and the production of non -transgenic tolerant plants using grafts. The genetic transformation of plants that overexploited cprap2 genes and their offspring demonstrated that they can survive at extreme temperatures; up to 12 days in heat and more than thirty days in the cold.
