Evidence of Coexistence of C3 and C4 Photosynthetic Pathways in a Green-Tide-Forming Alga, Ulva prolifera
Ulva prolifera, a typical green-tide-forming alga, can accumulate a large biomass in a relatively short time period, suggesting that photosynthesis in this organism, particularly its carbon fixation pathway, must be very efficient. Green algae are known to generally perform C₃ photosynthesis, but recent metabolic labeling and genome sequencing data suggest that they may also perform C₄ photosyn...
متن کاملIn situ growth potential of the subtidal part of green tide forming Ulva spp. stocks.
Ulva spp., the algae most responsible for green tides in Brittany (France), are found on the foreshore and in the most beachward wave area (MBWA) of many bays during green tide phenomena. These algae have recently been seen drifting at greater depths (reaching - 20 m). In view of the significant quantities of algae found at these depths, and the less favorable conditions for algal growth than i...
متن کاملSterols from the Green Alga Ulva australis
Three new sterols, (24R)-5,28-stigmastadiene-3β,24-diol-7-one (1), (24S)-5,28-stigmastadiene-3β,24-diol-7-one (2), and 24R and 24S-vinylcholesta-3β,5α,6β,24-tetraol (3), together with three known sterols (4-6) were isolated from the green alga Ulva australis. The structures of the new compounds (1-3) were elucidated through 1D and 2D nuclear magnetic resonance spectroscopy as well as mass spect...
متن کاملThe in vitro growth and differentiation of the alga Ulva rigida
The in vitro growth and differentiation of the alga Ulva rigida C. Agardh have been studied. Plants grown in enriched sea water (medium II and especially medium L) have a higher chlorophyll content and regularly release a large number of reproductive cells (in 10 days). This capability does not depend on the collecting season. It has been confirmed that axenic Viva cultures grown in solution de...
متن کاملThe ultrastructure of fertilization and zygote formation in the green alga Ulva mutabilis Foyn.
Fertilization and zygote formation in the multicellular green alga Ulva mutabilis Foyn were studied with the aid of transmission and scanning electron microscopes. The growth mutant 'slender' was used in this investigation. The initial contact between mating gametes is made by the flagella, whereupon cytoplasmic contact is established within a few seconds. Fusion of the cytoplasm of the 2 cells...
