UTILIZATION OF ZPT2-3 ZINC FINGER TYPE TRANSCRIPTIONAL FACTOR IN CONSTRUCTING PLANT WITH ENHANCED RESISTANCE TO DRYNESS

摘要

To investigate the function of ZPT2-3, petunia transformants overexpressing the ZPT2-3 gene under the control of the CaMV 35S promoter were generated to investigate the presence or absence of tolerance against desiccation stress treatment. Surprisingly, petunia plants transformants showed significant tolerance against desiccation as compared to the wild type plants. In addition, neither growth abnormality nor morphological abnormality was observed in petunia transformants, and thus overexpression of the ZPT2-3 gene was revealed to have no adverse effects on plant growth or such.
