“…For example, resting stage cells were found in the diatoms such as S. costatum (Itakura et al, 1992), Chaetoceros pseudocurvisetus Mangin (Kuwata et al, 1993;Oku and Kamatani, 1999), Leptocylindrus danicus Cleve (French and Hargraves, 1986) and C. wailesii (Nagai et al, 1995a). During the period from April to September, when the water column is stratified, conditions are thought to be unsuitable for vegetative growth of larger diatom species .…”

“…compressed with strongly condensed, granular chromosomes (Kennaway & Lewis, ). In the diatom Chaetoceros pseudocurvisetus , Oku & Kamatani () found changes in nucleotide content during resting‐stage formation. In the cyanobacterium Aphanizomenon ovalisporum , massive multiplication of the genome can occur in akinetes; the vegetative cells are also polyploid, but the copy number can be 15‐fold higher in akinetes (Sukenik et al., ).…”

The long‐term persistence of phytoplankton resting stages in aquatic ‘seed banks’

In the past decade, research on long-term persistence of phytoplankton resting stages has intensified. Simultaneously, insight into life-cycle variability in the diverse groups of phytoplankton has also increased. Aquatic 'seed banks' have tremendous significance and show many interesting parallels to terrestrial seed beds of vascular plants, but are much less studied. It is therefore timely to review the phenomenon of long-term persistence of aquatic resting stages in sediment seed banks. Herein we compare function, morphology and physiology of phytoplankton resting stages to factors central for persistence of terrestrial seeds. We review the types of resting stages found in different groups of phytoplankton and focus on the groups for which long-term (multi-decadal) persistence has been shown: dinoflagellates, diatoms, green algae and cyanobacteria. We discuss the metabolism of long-term dormancy in phytoplankton resting stages and the ecological, evolutionary and management implications of this important trait. Phytoplankton resting stages exhibiting long-term viability are characterized by thick, often multi-layered walls and accumulation vesicles containing starch, lipids or other materials such as pigments, cyanophycin or unidentified granular materials. They are reported to play central roles in evolutionary resilience and survival of catastrophic events. Promising areas for future research include the role of hormones in mediating dormancy, elucidating the mechanisms behind metabolic shut-down and testing bet-hedging hypotheses.

“…Studies have been conducted to identify the resting stage cells of diatom species such as S. costatum (Itakura et al, 1992), Chaetoceros pseudocurvisetus Mangin (Kuwata et al, 1993;Oku and Kamatani, 1999), Leptocylindrus danicus Cleve (French and Hargraves, 1986) and C. wailesii (Nagai et al, 1995), which are predominant species in Harima-Nada. It is well known that diatoms generally form resting stage cell in unsuitable conditions for vegetative growth (Itakura, 2000;Kuwata et al, 1993).…”
