FeMoco (FeMo cofactor) is the primary cofactor of nitrogenase. Nitrogenase is the enzyme that catalyzes the conversion of atmospheric nitrogen molecules N 2 into ammonia (NH 3) through the process known as nitrogen fixation. Because it contains iron and molybdenum, the cofactor is called FeMoco. Its stoichiometry is Fe 7 MoS 9 C.
Dipterocarpaceae is a family of flowering plants with 22 genera [3] and about 695 known species [4] of mainly lowland tropical forest trees. Their distribution is pantropical, from northern South America to Africa, the Seychelles, India, Indochina, Indonesia, Malaysia and Philippines. [5] [6] The greatest diversity of Dipterocarpaceae occurs in ...
In western Canada and the United States, a culturally modified tree (CMT) is one which has been modified by indigenous people as part of their tradition. Such trees are important sources for the history of certain regions. In British Columbia, one of the most commonly modified trees, particularly on the coast, is the Western Red Cedar.
It has an unusually diverse tree flora, with as many as 30 tree species at a single site including many relics of the ancient forest that once covered North America more widely. Along with the forest there is a rich undergrowth of ferns , fungi , herbaceous plants , shrubs and small trees as well as areas of glade , heath , shale , peat bog and ...

Others showed tree-like symbols and weapons, and many of the trees have horizontal carvings, like rings. [ 6 ] The best known examples of momori rakau are at Hāpūpū / J M Barker Historic Reserve , where the carvings and trees are protected by a fenced enclosure and the protection of being one of only two National Historic Reserves in New ...
A genetically modified tree (GMt, GM tree, genetically engineered tree, GE tree or transgenic tree) is a tree whose DNA has been modified using genetic engineering techniques. In most cases the aim is to introduce a novel trait to the plant which does not occur naturally within the species.
A dendrochronology, based on these trees and other bristlecone pine samples, extends back to about 9000 BC, albeit with a single gap of about 500 years. [20] [3] An older bristlecone pine was reportedly discovered by Tom Harlan in 2009, based on a sample core collected in 1957. According to Harlan, the tree was 5,062 years old and still living ...
