Effects of heat treatment on the symbiotic system of an aphid mycetocyte
Production of essential amino acids from glutamate by mycetocyte
symbionts of the pea aphid, Acyrthosiphon pisum.
The distribution of mycetocytes
varies, being located along the digestive tube or concentrated in certain regions of it.
, which are specialized fat body cells harboring uricolytic bacteria, have been identified from only one termite species, Mastotermes darwiniensis (Bandi and Sacchi 2000).
The primary and secondary symbionts were located in mycetocytes
, microbe-containing structures commonly found in hemipteran insects (Baumann 2006), of D.
Phase contrast and electron microscopy of the mycetocytes
and symbionts of the pea aphid Acyrthosiphon pisum.
This ultra-structural examination afforded an additional control: commensals present in the lumen and specialized to that environment might not grow on culture plates, but commensals and mycetocytes
, insect cells that incorporate microorganisms (Chapman, 1969), can be distinguished at the ultrastructural level (Smith, 1968).
