Application

Murashige and Skoog medium is a widely used plant tissue culture growth medium. M&S Basal Medium contains macronutrients that include high levels of nitrate and organic additives such as agar, sugars, vitamins and growth regulators. Important growth regulators frequently added to M&S include IAA (auxin/morphogen) and the Kinetin (cytokinin/cell division promoter).

Biochem/physiol Actions

Murashige and Skoog medium can be reconstituted from powder or by combining products that are major components of complete M&S medium, such as macronutrient mixtures and vitamin mixtures. Murashige and Skoog Salt mixture (M8280) contain the macronutrients and micronutrients of the original classic formulation with sodium nitrate substituted for ammonium nitrate. It can be combined with M&S vitamins or Gamborg′s vitamins and supplemented with sucrose, agar, auxins (IAA) and cytokinins (Kinetin) to generate a complete medium for growth plant tissue culture.

Preparation Note

Modified by replacing ammonium nitrate with sodium nitrate.

Other Notes

NH4-free
With the macro- and micronutrients as described by Murashige and Skoog (1962).

Mechanical stimulation of plants triggers a cytoplasmic Ca(2+) increase that is thought to link the touch stimulus to appropriate growth responses. We found that in roots of Arabidopsis thaliana, external and endogenously generated mechanical forces consistently trigger rapid and transient
