Key Discovery in Identifying Drought-Resistant Trees!
Korea Forest Research Institute Unveils Mechanism of Oak Tree Drought Resistance Through Genetic and Physiological Studies
The Korea Forest Research Institute (Director: Bae Jae-soo) part of the Korea Forest Service has announced a significant breakthrough in finding environmental stress factors that can evaluate the drought resistance of oak trees. This discovery comes as part of ongoing efforts to combat climate change.
The research team focused on two species: the Sawtooth Oak which grows in dry regions and the Mongolian Oak which thrives in more humid areas. By analyzing RNA transcriptomes and physiological active substances the team sought to uncover the mechanisms behind the drought resistance of these oak species.
The results revealed that while the growth of the Sawtooth Oak in dry environments was delayed its photosynthetic mechanisms remained largely intact showing superior drought resistance and recovery compared to the Mongolian Oak.
Through this research the team identified critical environmental stress markers such as malondialdehyde (MDA) hydrogen peroxide (H2O2) and proline which are key indicators for breeding drought-resistant trees. Additionally they found differences in the drought response mechanisms between tree species highlighting the need for further refinement and application of these indicators in future studies.
With the increasing importance of breeding plants that can withstand global warming the research findings were also recognized academically being published in Volume 15 of the international journal Frontiers in Plant Science.
Dr. Lim Hye-min from the Tree Resources Research Division at the National Institute of Forest Science stated These findings will contribute to developing genetic and physiological selection techniques for breeding drought-resistant trees and establishing a digital evaluation framework. We will continue our efforts to support sustainable forest management by researching tree species that exhibit superior adaptation and growth under climate change conditions.
