General description

Agar (Type A) is extracted from agarocytes of the red alga Rhodophyceae. It is a polysaccharide complex, consisting of a neutral gelling fraction, agarose, and a non-gelling fraction, agaropectin. Type-A agar forms a thermoreversible gel, and is most suitable for plant cell culture.


Type A agar has been used:
  • to perform metal(loid)-related phenotyping of the Arabidopsis thaliana metal-sensitive mutant strains
  • as a component of Murashige and Skoog (MS) media to culturing Arabidopsis thaliana seeds
  • to culture Cicer arietinum L. (Chickpea) seeds for Agrobacterium rhizogenes mediated root transformation

Plants live in close relationships with complex populations of microorganisms, including rhizobacterial species commonly referred to as plant growth-promoting rhizobacteria (PGPR). PGPR are able to improve plant productivity, but the molecular mechanisms involved in this process remain largely unknown. Using
