The syntenic X-chromosome region of three marsupial species (wallaby, Macropus eugenii; Tasmanian devil, Sarcophilus harrisii, and opossum, Monodelphis domestica) and one monotreme (platypus, Ornithorhynchus anatinus
) genome, focusing on the chromosomal region around the HPRT locus, has been systematically searched and no sequences similar to PLAC1 have been found.
The platypus, with the scientific name Ornithorhynchus anatinus
, is a cute and furry mammal that has a beak and lays eggs.
Isolation of Mucor corcinelloides from a case of ulcerative mycosis of platypus (Ornithorhynchus anatinus
), and a comparison of the response of Mucor circinelloides and Mucor amphibiorum to different culture temperatures.
Naturalists thought the first dried specimen (reaching England in 1799) was a hoax yet this 'highly interesting novelty' would take another 90 years to decide on its classification and nomenclature beginning with the popular forms of duck-bill mole and water-mole to Blumenbach's Ornithorhynchus paradoxus (1798, 1800) to George Shaw's Platypus anatinus (flat footed duck bill, 1799) before finally settling on Ornithorhynchus anatinus
(bird-like snout) as the name platypus had previously been used in 1793.
Splenic hemopoiesis of the platypus (Ornithorhynchus anatinus
): Evidence of primary hemopoiesis in the spleen of a primitive mammal.
