This transport process is called translocation. [2] In trees, the phloem is the innermost layer of the bark, hence the name, derived from the Ancient Greek word φλοιός (phloiós), meaning "bark". [3] [4] The term was introduced by Carl Nägeli in 1858. [5] [6] Different types of phloem can be distinguished. The early phloem formed in the ...
Twin-arginine translocation pathway, a protein export pathway found in plants, bacteria, and archaea; Translocation (botany), transport of nutrients through phloem; Protein translocation, also called protein targeting, a process in protein biosynthesis; Species translocation, movement of a species, by people, from one area to another
The translocation of 254 black bears to the Ozark Mountains in Arkansas resulted in more than 2,500 individuals 11 years later and has been seen as one of the most successful translocations in order Carnivora. [33] Another example of successful translocation is the gray wolf translocation in Yellowstone National Park.
Auxin also regulates the two types of cell in the vascular cambium, ray and fusiform initials. Regulation of these initials ensures the connection and communication between xylem and phloem is maintained for the translocation of nourishment and sugars are safely being stored as an energy resource.
The pressure flow hypothesis, also known as the mass flow hypothesis, is the best-supported theory to explain the movement of sap through the phloem of plants. [1] [2] It was proposed in 1930 by Ernst Münch, a German plant physiologist. [3]
The translocation efforts to create a wild northern bobwhite quail population in central Pennsylvania are off to a strong start as it appears there may be more birds now than in the spring. The ...
Xylem (blue) transports water and minerals from the roots upwards. Xylem is one of the two types of transport tissue in vascular plants, the other being phloem; both of these are part of the vascular bundle.
Otis Freeman Curtis (12 February 1888, Sendai, Japan – 4 July 1949, Cape Cod, Massachusetts) [1] was an American botanist and plant physiologist, at the State Agricultural Experimental Station, and professor of botany at Cornell University. [2]: 66 He made important contributions to the study of translocation. [2]: 66
