Glycerophosphocholines of the Earthworm, Pheretima asiatica.

Glycerophosphocholines of the earthworm, Pheretima asiatica.

The lipid composition of the earthworm, Pheretima asiatica (Annelida), was analyzed. Four glycerophospholipids, together with four known glycosphingolipids, were isolated in pure form. The former four were 1-alkyl 2-acyl glycerophosphocholines possessing a C17:0 and/or C18:1 fatty acid residue. Their structures, including the position and geometry of the double bond, were determined on the base...

Effects of catecholamines on the neuromuscular junction of the somatic muscle of the earthworm Pheretima communissima.

The Role of the Earthworm, Pheretima (Metaphire) hilgendorfi, in Terrestrial Ecosystem Nutrient Cycling

In the gut tissues and contents of the earthworm Pheretima (Metaphire) hilgendorfi, cellulase activity which contributes to the terrestrial ecosystem nutrient cycling has been detected. The origin of the cellulase production, whether it is the earthworm itself or the microorganisms, has not been established at the molecular level. In our study, a cellulase [endo-β-1,4glucanase (EGase), EC3.2.1....

Syntheses of glycoclusters containing a phosphocholine residue related to a glycosphingolipid from the earthworm Pheretima hilgendorfi.

Three types of glycoclusters related to an amphoteric glycosphingolipid found in the earthworm Pheretima hilgendorfi were synthesized. The glycoclusters were prepared from a common precursor and a simple approach for the rational design of a glycocluster was developed.

Fifteen new earthworm mitogenomes shed new light on phylogeny within the Pheretima complex.

The Pheretima complex within the Megascolecidae family is a major earthworm group. Recently, the systematic status of the Pheretima complex based on morphology was challenged by molecular studies. In this study, we carry out the first comparative mitogenomic study in oligochaetes. The mitogenomes of 15 earthworm species were sequenced and compared with other 9 available earthworm mitogenomes, w...
