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.

Karyotype analysis, genome organization, and stable genetic transformation of the root colonizing fungus Piriformospora indica.

Alga Zuccaro et al.

Fungal genetics and biology : FG & B, 46(8), 543-550 (2009-04-09)

Piriformospora indica (Basidiomycota, Sebacinales) is a root colonizing fungus which is able to increase biomass and yield of crop plants and to induce local and systemic resistance to fungal diseases and tolerance to abiotic stress. A prerequisite for the elucidation

Isolation of cyanophages from aquatic environments.

Andrew D Millard

Methods in molecular biology (Clifton, N.J.), 501, 33-42 (2008-12-11)

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

Improvement of Agrobacterium-mediated transformation in Hi-II maize (Zea mays) using standard binary vectors.

Juan M Vega et al.

Plant cell reports, 27(2), 297-305 (2007-10-17)

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

Dancing with the Stars: Using Image Analysis to Study the Choreography of the Endoplasmic Reticulum and Its Partners and of Movement Within Its Tubules.

Lawrence R Griffing

Methods in molecular biology (Clifton, N.J.), 1691, 75-102 (2017-10-19)

In this chapter, approaches to the image analysis of the choreography of the plant endoplasmic reticulum (ER) labeled with fluorescent fusion proteins ("stars," if you wish) are presented. The approaches include the analyses of those parts of the ER that

In-vitro Strain and Modulus Measurements in Porcine Cervical Lymph Nodes.

Queeny Wing-Han Yuen et al.

The open biomedical engineering journal, 5, 39-46 (2011-06-07)

Cervical lymph nodes are common sites of metastatic involvement in head and neck cancers. These lymph nodes are superficially located and palpation is a common practice for assessing nodal hardness and staging cancer which is, however, too subjective and with
