| Zusammenfassung |
| Recent studies showed changes in phytoplankton lipid composition during viral
infection and have indicated roles for specific lipids in the mechanisms of
algal virus-host interaction. To investigate the generality of these findings
and obtain a better understanding of the allocation of specific lipids to
viruses, we studied the intact polar lipid (IPL) composition of virally
infected and non-infected cultures of the prymnesiophyte Phaeocystis
globosa G(A) and its lytic virus PgV-07T. The P. globosa IPL
composition was relatively stable over a diel cycle and not strongly affected
by viral infection. Glycolipids, phospholipids and betaine lipids were
present in both the host and virus, although specific groups such as the
diacylglyceryl-hydroxymethyltrimethyl-β-alanines and the
sulfoquinovosyldiacylglycerols, were present in a lower proportion or were
not detected in the virus. Viral glycosphingolipids (vGSLs), which have been
shown to play a role in the infection strategy of the virus EhV-86, infecting
the prymnesiophyte Emiliania huxleyi CCMP374, were not encountered.
Our results show that the involvement of lipids in virus–algal host
interactions can be very different amongst virus–algal host systems. |
