Climate change: Improving heat tolerance in trees
Is it possible to improve tolerance of trees to high temperatures and other types of stress derived of climate change? Scientists are studying the tolerance of trees using molecular and biotechnological tools. Biologists succeeding in making popular trees significantly more tolerant to high temperatures, drought, and the presence of weed-killers.
Is it possible to improve tolerance of trees to high temperatures and other types of stress derived of climate change? A research group of the Universidad Politcnica de Madrid (UPM), led by Luis Gmez, a professor of the Forestry School and the Centre for Plant Biotechnology and Genomics (CBGP), is studying the tolerance of trees using molecular and biotechnological tools. The research work was published in the last issue of the journal Plant Physiology.The obtained poplars in this project, with the collaboration of the Universidad de Mlaga, are significantly more tolerant to high temperatures than the control trees. These trees are also more tolerant to drought, to the presence of weed-killer, to in vitro and ex vitro crops, to contamination and other ways of abiotic stress that have an applied interest for forestry. This work is a continuation of a project started by of a research team of the UPM a decade ago. This study focuses on mechanisms that plant cells use to protect themselves from stress factors.Due to the human pressure on forests, the Food and Agriculture Organization of the United Nations (FAO) is promoting intensive plantations as an alternative to meet the global demand of wood and other products. Besides, plantations have social and economic benefits (job creation, wealth and rural development). This model change has significant ecological consequences.The role of forests is essential for climate change mitigation and biodiversity preservation, amongst others. A documentary “El Bosque Protector,” co-produced by the UPM and available on “A la Carta” of RTVE shows the result of this study. Tree farming plantations as a realistic alternative will be possible if the current yield significantly increases. …
