  abstract = {{V}iral abundance and processes in the water {C}olumn and sediments are well studied for some systems; however, we know relatively little about virus-host interactions on particles and how particles influence these interactions. {H}ere we review virus-prokaryote interactions on inorganic and organic particles in the water column. {P}rofiting from recent methodological progress, we show that confocal laser scanning microscopy in combination with lectin and nucleic acid staining is one of the most powerful methods to visualize the distribution of viruses and their hosts on particles such as organic aggregates. {V}iral abundance on suspended matter ranges from 10(5) to 10(11) ml(-1). {T}he main factors controlling viral abundance are the quality, size and age of aggregates and the exposure time of viruses to aggregates. {O}ther factors such as water residence time likely act indirectly. {O}verall, aggregates appear to play a role of viral scavengers or reservoirs rather than viral factories. {A}dsorption of viruses to organic aggregates or inorganic particles can stimulate growth of the free-living prokaryotic community, e.g. by reducing viral lysis. {S}uch mechanisms can affect microbial diversity, food web structure and biogeochemical cycles. {V}iral lysis of bacterio- and phytoplankton influences the formation and fate of aggregates and can, for example, result in a higher stability of algal flocs. {T}hus, viruses also influence carbon export; however, it is still not clear whether they short-circuit or prime the biological pump. {T}hroughout this review, emphasis has been placed on defining general problems and knowledge gaps in virus-particle interactions and on providing avenues for further research, particularly those linked to global change.},
