What is it about?
In the present study, we utilized AtCBF3-transgenic potato plants to investigate whether overexpression of AtCBF3 could enhance the tolerance of the potato to high temperature. In addition, we also performed a preliminary examination of the regulatory pathway that plants use to resist high temperature in the presence of AtCBF3 and the mechanism involved in high-temperature-induced expression of AtCBF3.

Why is it important?
Transformation of tomato plants with the AtCBF3 gene enhanced tolerance to high temperatures. AtCBF3 improved the capacities of photosynthesis and antioxidant defense by regulating the expression of genes involved in these functions, and this enhanced tolerance might not depend on the regulatory pathways in which HSP70 is involved.
Perspectives
This article may interest to study the other important role of CBF on thr stress tolerance other than only cold or drought stress.
