A genetically reformed tree (GMt, GM tree, genetically engineered tree, GE tree or transgenic tree) is a tree whose DNA has been reformed using genetic engineering methods. In most cases the goal is to introduce a novel trait to the plant which does not take place naturally within the species. Examples contain resistance to certain pests, diseases, environmental conditions, and herbicide tolerance, or the adaptation of lignin levels in order to bring down pulping costs.


Lignin alteration

Lignin abolition from wood fibers conventionally depends on costly and environmentally hazardous chemicals. By developing low-lignin GM trees it is expected that pulping and bleaching processes will need fewer inputs, therefore, mills provided by low-lignin GM trees may have a lesser impact on their surrounding ecosystems and communities. Nevertheless, it is argued that reductions in lignin may understand the structural integrity of the plant, thereby making it more permitting to wind, snow, pathogens and disease, which could be a key pesticide use exceeding that on traditional plantations.

Frost tolerance

Genetic moderation can let trees to cope with abiotic stresses connate that their geographic range is broadened.

Freeze-tolerant GM eucalyptus trees for making use in southern US plantations are nowadays being experimented in open air sites with such an objective in mind.

Until now the cultivation of eucalyptus has only been attainable on the southern tip of Florida, freeze-tolerance would substantially extend the cultivation range northwards.

Reduced vigour

Orchard trees require a rootstock with reduced vigour to allow them to prevail small. Genetic modification could allow the elimination of the rootstock, by making the tree slight vigorous, hence decreasing its height when fully grown. Research is being done into which genes are in control of for the robustness in orchard trees (such as apples, pears, etc).

Accelerated growth

There is perturbed that such objectives may further exacerbate the negative impacts of plantation forestry.

Increased water and soil nutrient dictate from faster growing species may lead to irrecoverable losses in site fecundity and further impinge upon neighbouring communities and ecosystems.

Researchers at the University of Manchester's Faculty of Life Sciences modified two genes in popular trees, called PXY and CLE, which are accountable for the rate of cell division in tree trunks.

As a result, the trees are growing twice as quick as normal, and also end up being taller, wider and with additional leaves.

Disease resistance

Ecologically inspired research into genetic modification is underway. Certain diseases have modification is underway. Certain diseases have reduced the populations of these emblematic species to the range that they are mostly lost in the wild.

Genetic modification is being followed concurrently with traditional breeding techniques in a try to endow these species with disease resistance.


Genetically altered forest trees are not yet approved ("deregulated") for commercial use with the deviation of insect-resistant poplar trees in China and one case of GM Eucalyptus in Brazil. Several genetically altered forest tree species are undergoing field trials for deregulation, and much of the research is being accomplished by the pulp and paper industry, primarily with the aim of raising the productivity of existing tree stock.
