Micropropagation

A technique where small pieces of plant tissue are grown in a sterile, nutrient-rich medium to produce clones of the original plant.

Tissue Culture

Refers to the sterilized container where small plant tissues are grown in micropropagation.

Explant

The small piece of plant tissue used in micropropagation.

Agar

A solid media containing nutrients like glucose and amino acids, used to support the growth of plant explants.

Study Notes

Micropropagation and Tissue Culture

  • Micropropagation uses tissue culture to grow plants from cells.
  • Aseptic conditions are crucial, sterilizing the workspace and equipment to prevent competing microorganisms.
  • Plant material (explants) are taken, often from leaves, roots, or buds, due to their active mitosis.
  • Explants are sterilized using bleach or alcohol.
  • Explants are placed on agar containing nutrients like glucose (for respiration) and amino acids (for protein synthesis).
  • Cell division (mitosis) forms a callus.
  • The callus can be subdivided to create more calluses.
  • Hormones (auxin or cytokines) can be used to induce root formation or other desired development.
  • Plantlets are transitioned to soil or water, eventually to a greenhouse.

Advantages of Micropropagation

  • Preserves desirable traits in offspring (like taste, quantity of fruit).
  • Faster production than growing from seeds.
  • Enables seedless fruit production.

Disadvantages of Micropropagation

  • Low genetic diversity.
  • Increased susceptibility to disease as clones share the same genetic information.
