TRANSCRIPTION FACTORS ISOLATED FROM CARICA PAPAYA AND USE THEREOF FOR OBTAINING PLANTS TOLERANT TO EXTREME TEMPERATURES

摘要

The present invention relates to four CpRap2 genes isolated from Carica papaya, identified as CpRap2.4a, CpRap2.4b, CpRap2.1, CpRap2.10 and consisting of sequences SEQ. ID NO: 1, SEQ. ID NO: 2, SEQ. ID NO: 3 and SEQ. ID NO: 4, as well as to genetic transformation methods for the overexpression of said genes and the production of tolerant non-transgenic plants using scions. The genetic transformation of plants that overexpress the CpRap2 genes and the scions thereof has demonstrated that they can survive at extreme temperatures; up to 12 days in heat and more than 30 days in cold.
