Light-Harvesting System of the Red Alga Gracilaria tikvahiae: II. Phycobilisome Characteristics of Pigment Mutants.
Phycobilisomes were isolated from wild type Gracilaria tikvahiae and a number of its genetically characterized Mendelian and non-Mendelian pigment mutants in which the principal lesions result in an increase or decrease in the accumulation of phycoerythrin. Both the size and phycoerythrin content of the phycobilisomes are proportional to the phycoerythrin content of the crude algal extracts. In...
متن کاملLight-Harvesting System of the Red Alga Gracilaria tikvahiae: I. Biochemical Analyses of Pigment Mutations.
Wild type Gracilaria tikvahiae, a macrophytic red alga, and fourteen genetically characterized pigment mutants were analyzed for their biliprotein and chlorophyll contents. The same three biliproteins, phycoerythrin, phycocyanin, and allophycocyanin, which are found in the wild type are found in all the Mendelian and non-Mendelian mutants examined. Some mutants overproduce R-phycoerythrin while...
متن کاملThe invasive red alga Gracilaria vermiculophylla in the Baltic Sea: adaptation to brackish water may compensate for light limitation
The recent introduction of Gracilaria vermiculophylla (Rhodophyta) to the Kiel Fjord area was a reason for concern, since this red macroalga perfoms best under mesohaline conditions and thus appears well adapted to thrive and spread in the Baltic Sea environment. A systematic survey on a coastal range of 500 km in 2006 and 2007 indicated considerable multiplication and spreading of G. vermiculo...
متن کاملMycosporine-like amino acids in the marine red alga Gracilaria cornea — effects of UV and heat
Ultraviolet (UV)-absorbing mycosporine-like amino acids (MAAs) were separated from a marine red alga Gracilaria cornea using HPLC. The isolated MAAs were identified as porphyra-334 and/or shinorine by comparing them with various standards. No in vivo induction of MAAs was detected in G. cornea even when the organism was grown for 4–5 days either in the presence of UV-A and UV-B only or in combi...
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...
