celltype. For plantcells, enrichment with nitrogen, phosphorus, and potassium is especially important. Water is provided as a constituent part of the gel media.
Uses
A plantcell callus consists of somatic undifferentiated cells from an adult subject plant.
A callus is not necessarily genetically homogeneous because a callus is often made from structural tissue, not individual cells. Nevert
