چکیده
We report here the effects of cadmium on metabolome macroalga Gracilaria caudata. The IC50 3 mg/L (12 µM) was obtained after 48 hrs exposure and induced lower photosynthesis efficiency. Threshold concentrations determined by Brazilian Environmental Council (CONAMA) in marine waters (0.04 mg/L) effluent discharge (0.2 were also tested, latter changed photosynthetic efficiency similarly to IC50. A total 43 metabolites identified, including monosaccharides, carboxylic acids, amino acids. By an unsupervised PCA, we identified significative alterations An OPLS-DA analysis showed that Cd2+ caused variation 20 metabolites, mainly glyoxylate-related, ascorbate, floridoside proline. Five metabolic pathways altered accumulation carbon metabolism intermediates antioxidant responses Cd2+. recommend a review toxicity parameters methods guide environmental policies levels waters.

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 کاملAgars from three species of Gracilaria (Rhodophyta) from Yucatán Peninsula.
Gracilaria cervicornis, Gracilaria blodgettii and Gracilaria crassissima growing along the coasts of Yucatán were investigated for their agar content. The effect of different concentrations of NaOH in the alkali treatment was evaluated. The three species of Gracilaria produced agars, both native and alkali treated, with different properties confirming the heterogeneity of the agar polymers in t...

* Corresponding author Genes differentially expressed between tetrasporophytes and female gametophytes of Gracilaria/Gracilariopsis lemaneiformis were isolated by suppression subtractive hybridization (SSH) and screened by dot-blot macroarrays. Different expression profiles of selected clones based on the results of dot-blot macro-arrays were verified using virtual Northern blots. Totally, 14 p...
