Methylation-independent imprinting has been observed for some imprinted loci in mammals [ 54] and histone methylation by Polycomb group proteins has been shown to regulate several imprinted genes in plants [ 37, 44, 55].
Such imprinting has been found in other contexts.
Since then, imprinting has been observed in a number of bird species including geese, ducks and, of course, cranes.
Preeclampsia, for example, in which disordered imprinting has been implicated, also demonstrates growth restriction in utero.
Imprinting has been able to explain certain predicaments of life in utero.
Imprinting has been intensively studied only in birds, especially chickens, ducks, and geese, but a comparable form of learning apparently occurs in the young of many mammals and some fishes and insects.
Molecular imprinting has become an established technique.
Since then, the behavior, known as imprinting, has also been linked to mate choice.
Although molecular imprinting has been around for over 30 years, recently this technology has made rapid developments.
Beyond these applications, in the past few years molecular imprinting has become a tool for producing new kinds of catalysts.
Molecular imprinting has proved to be an effective technique for the creation of recognition sites on a polymer scaffold.
