Chromosomal and mutagenic study of the marine macroalga, Gracilaria tenuistipitata

Journal of Applied Phycology, 1995
A pressing need of algal aquaculture is the availability of strains with favourable characteristics. Since this goal cannot be achieved easily by traditional breeding methods for Gracilaria tenuistipitata, we developed mutagenesis and selection procedures that bypass the necessity for protoplast isolation and cultivation.

Biochemical and physiological responses of Gracilaria tenuistipitata under two different nitrogen treatments

Physiologia Plantarum, 1993
The influence of nitrogen on ribulose‐1.5‐bisphosphate carboxylase/oxygenase (Rubisco. EC 4.1.1.39) content is poorly understood in macroalgae. N‐deficient Gracilaria tenuistipitata Zhang et Xia var. liui was cultivated in the laboratory under constant light intensity and temperature. Biochemical and physiological variables were monitored after a high (

Photosynthetic response of P‐deficient Gracilaria tenuistipitata under two different phosphate treatments

Physiologia Plantarum, 1996
Phosphorus‐deficient Gracilaria tenuistipitata Zhang et Xia was cultured for 15 days at two different inorganic phosphate (Pi) concentrations: 3 μM (low Pi treatmenl) or 30 μM phosphate (high Pi treatment). The amount of ribulose‐l,5‐bisphosphate carboxy‐lase/oxygenase (Rubisco), phycobiliproteins, Chl a and total soluble proteins were higher in the ...

Comparison of ethanol production from Gracilaria fisheri and Gracilaria tenuistipitata cultivated in aquaculture system in Thailand

Journal of Applied Phycology, 2018
Several species of seaweeds contain higher amounts of polysaccharides and low lignin. These species can be sources for bioethanol production and can be utilized for other biochemical production. In Thailand, large amounts of the red seaweeds Gracilaria fisheri and G.

Reference genes for transcript quantification in Gracilaria tenuistipitata under drought stress

Journal of Applied Phycology, 2016
Gracilaria tenuistipitata is a red macroalga often found in intertidal environments, where it is frequently under drought stress due to tidal water scarcity. In order to be able to study the molecular mechanisms involved in G. tenuistipitata resistance to dehydration, we have done a dehydration assay, tested different RNA extraction protocols, and ...

The α-galactosidase of Gracilaria tenuistipitata and G. sordida (Gracilariales, Rhodophyta)

Phycologia, 1990
Abstract An α-galactosidase (α-galactopyranoside galactohydrolase, EC 3.2.1.22) has been isolated from the red seaweeds Gracilaria tenuistipitata Zhang et Xia from China and Gracilaria sordida W. Nelson from New Zealand, and its properties have been investigated.

Analysis of expressed sequence tags from the agarophyte Gracilaria tenuistipitata (Rhodophyta)

Journal of Applied Phycology, 2011
A total of 3,631 expressed sequence tags (ESTs) were established from two size-selected cDNA libraries made from the tetrasporophytic phase of the agarophytic red alga Gracilaria tenuistipitata. The average sizes of the inserts in the two libraries were 1,600 bp and 600 bp, with an average length of the edited sequences of 850 bp. Clustering gave 2,387

Induction of Oxidative Stress in the Red Macroalga Gracilaria tenuistipitata by Pollutant Metals

Archives of Environmental Contamination and Toxicology, 2003
Heavy metals are environmental pollutants that have the potential to induce severe stress-reactions in organisms on land as well as in the sea. We have studied effects of short term sublethal concentrations of copper (Cu2+) and cadmium (Cd2+) on the reactive oxygen metabolism of the marine red macroalga Gracilaria tenuistipitata.

Some aspects of the growth of Gracilaria tenuistipitata in pond culture

Hydrobiologia, 1993
The effect of temperature, salinity, nitrogen, culture density and depth on the growth of Gracilaria tenuistipitata were investigated between April 1985 and March 1986 in outdoor ponds in Guangxi Province,South China. The mean annual growth rate was 2.4% per day.

RNA Isolation method for polysaccharide rich algae: agar producing Gracilaria tenuistipitata (Rhodophyta)

Journal of Applied Phycology, 2007
RNA isolation is essential to study gene expression at the molecular level. However, RNA isolation is difficult in organisms (plants and algae) that contain large amounts of polysaccharides, which co-precipitate with RNA. Currently, there is no commercial kit available, specifically for the isolation of high-quality RNA from these organisms ...
