General description

Agar or Agar-agar is one of the major components found in the cell wall of red algae. It is a polysaccharide complex, comprising about 70% agarose and 30% agaropectin.

Application

Washed agar has been used:
  • as a supplement (0.9% w/v) to Murashige and Skoog basal medium for plant growth
  • in the preparation of cocultivation medium for Agrobacterium tumefaciens mediated transformation in maize (Zea mays) hybrid Hi-II
  • as a component in the complete medium to regenerate protoplasts of Piriformospora indica
  • as a clean agar medium to culture Synechococcus WH7803 strain

Biochem/physiol Actions

Agar is an ester of sulfuric acid in a linear galactan form, that makes it soluble in hot water and insoluble in cold. Washed agar contain less impurities and low level of nutrients.

Cyanophages are a group of viruses which specifically infect cyanobacteria. The cyanobacteria are predominantly aquatic phototrophic bacteria and the two dominant genera Synechococcus and Prochlorococcus contribute significantly to primary production in the oceans. Cyanophages that infect marine cyanobacteria were first

High-frequency transformation of maize (Zea mays L.) using standard binary vectors is advantageous for functional genomics and other genetic engineering studies. Recent advances in Agrobacterium tumefaciens-mediated transformation of maize have made it possible for the public to transform maize using

Water is arguably the most important constituent of microbial microhabitats due to its control of physical and physiological processes critical to microbial activity. In natural environments, bacteria often live on unsaturated surfaces, in thin (micrometric) liquid films. Nevertheless, no experimental
