Isolated transcription factors of Carica papaya and their application to obtain extreme temperature tolerating plants

摘要

The hereby invention provides four genes CpRap2 isolated from Carica papaya identified as CpRap2.4a, CpRap2.4b, CpRap2.1, CpRap2.10 and that consist of SEQ. ID NO: 1, SEQ. ID NO: 2, SEQ. ID NO: 3 and SEQ. ID NO: 4, as well as the genetic transformation methods for the overexpression of these genes and the obtaining of tolerant non-transgenic plants through grafts. Genetic transformation of plants that overexpress genes CpRap2 and their grafts showed they could survive extreme temperatures up to 12 days for heat and more than 30 days for cold.
