Transcriptome profiling of sulfate deprivation responses in two agarophytes Gracilaria changii and Gracilaria salicornia (Rhodophyta)
Seaweeds survive in marine waters with high sulfate concentration compared to those living at freshwater habitats. The cell wall polymer of Gracilaria spp. which supplies more than 50% of the world agar is heavily sulfated. Since sulfation reduces the agar quality, it is interesting to investigate the effects of sulfate deprivation on the sulfate contents of seaweed and agar, as well as the met...
متن کاملUNIVERSITY OF HAWAI'I LIBRARY INFLUENCE OF ULTRAVIOLET RADIATION ON THE PIGMENTATION AND GROWTH OF THE RED ALGA, GRACILARIA sALICORNIA
Physiological damage to macroalgae from both UVA (320-400 nm) and UVB (280-320 nm) radiation is well documented in the scientific literature. Due to the occurrence of mycosporine-like amino acids (MAAs) in marine algae from the poles to the tropics, and their UV absorption maxima between 310 and 360 nm, it is assumed that MAAs act as sunscreens to counter this stress while allowing the light-ha...
متن کاملMetabolomic Assessment of Induced and Activated Chemical Defence in the Invasive Red Alga Gracilaria vermiculophylla
In comparison with terrestrial plants the mechanistic knowledge of chemical defences is poor for marine macroalgae. This restricts our understanding in the chemically mediated interactions that take place between algae and other organisms. Technical advances such as metabolomics, however, enable new approaches towards the characterisation of the chemically mediated interactions of organisms wit...
متن کاملDistribution of invasive red alga Womersleyella setacea (Hollenberg) R.E. Norris (Rhodophyta, Ceramiales) in the Adriatic Sea
Womersleyella setacea (Hollenberg) R.E. Norris (Rhodophyta, Ceramiales) is an invasive macrophyte in the Mediterranean Sea, first recorded from the coast of Italy in 1986. This is a review of the geographic distribution and depth limits of W. setacea invasion in the Adriatic Sea since its first record in 1997. Algal turfs were collected and examined from different locations in the Croatian part...
متن کاملRoadside Survey of Ants on Oahu, Hawaii
Hawaii is home to over 60 ant species, including five of the six most damaging invasive ants. Although there have been many surveys of ants in Hawaii, the last island-wide hand-collection survey of ants on Oahu was conducted in 1988-1994. In 2012, a timed hand-collection of ants was made at 44 sites in a systematic, roadside survey throughout Oahu. Ants were identified and species distribution ...
