Massive <i>Ulva</i> Green Tides Caused by Inhibition of Biomass Allocation to Sporulation

The green seaweed <i>Ulva</i> spp. constitute major primary producers in marine coastal ecosystems. Some <i>Ulva</i> populations have declined in response to ocean warming, whereas others cause massive blooms as a floating form of large thalli mostly composed of uniform somat...

description The green seaweed <i>Ulva</i> spp. constitute major primary producers in marine coastal ecosystems. Some <i>Ulva</i> populations have declined in response to ocean warming, whereas others cause massive blooms as a floating form of large thalli mostly composed of uniform somatic cells even under high temperature conditions—a phenomenon called “green tide”. Such differences in population responses can be attributed to the fate of cells between alternative courses, somatic cell division (vegetative growth), and sporic cell division (spore production). In the present review, I attempt to link natural population dynamics to the findings of physiological in vitro research. Consequently, it is elucidated that the inhibition of biomass allocation to sporulation is an important key property for <i>Ulva</i> to cause a huge green tide.
