GM trees under experimental development have been modified with traits intended to provide benefit to industry, foresters or consumers. Due to high regulatory and research costs, the majority of genetically modified trees in silviculture consist of plantation trees, such as eucalyptus, poplar, and pine.
Plants are also used as feedstock for many industrial products including timber, paper and textiles, as well as a wide range of chemicals. Ornamental plants give millions of people pleasure through gardening, and floriculture is a popular pastime among many.

Grain, fruit, and vegetables are basic human foods and have been domesticated for
Although there are some differences between oxygenic photosynthesis in plants, algae, and cyanobacteria, the overall process is quite similar in these organisms.

Plant breeding can be performed using many different techniques, ranging from the selection of the most desirable plants for propagation, to methods that make use of knowledge of genetics and chromosomes, to more complex molecular techniques. Genes in a plant are what determine what type of qualitative or quantitative traits it will have.
In addition, climate change has caused challenges like early spring and late frosts, flooding, drought, and extreme heat, all of which effect fruit trees. Severe droughts and flooding affect the trees' growth, making them more susceptible to pests and diseases. Extreme heat can damage growing fruit directly on the tree. [6]
