PGRs are the chemical switches dictating whether a cell multiplies, forms roots, or shoots. PGR Category Key Examples Primary Role in Tissue Culture IAA, IBA, NAA, 2,4-D plant tissue culture ppt pdf
Living plant tissues cannot be autoclaved. Surface sterilization removes surface-dwelling microbes without killing the plant cells. The tissue is washed under running tap water with a mild surfactant (Tween-20), followed by immersion in chemical sterilants within the LAF cabinet:

Storing rare or endangered species in "gene banks" without requiring vast tracts of land. Key Applications of Plant Tissue Culture This public
Plant tissue culture has a rich history, with the concept established by the pioneering scientist in the early 20th century, earning him the title "Father of Tissue Culture." The discovery of plant growth regulators (hormones) like auxins and cytokinins in the mid-20th century was a pivotal moment, allowing researchers to manipulate cell division and differentiation more effectively. Since then, the field has evolved into a powerful tool with countless applications, from mass-producing identical, disease-free plants to conserving endangered species and engineering new genetic traits.
