Understanding this lineage offers perspective on contemporary practices.
  • Gain insights into the essential components and rigorous protocols for establishing and maintaining a sterile plant tissue culture laboratory, covering everything from facility design considerations to sterilization techniques crucial for preventing contamination and ensuring experimental success in sensitive plant material.
  • Explore the critical role of nutrient media formulation, including the precise balance of macro and micronutrients, vitamins, and carbon sources required to support optimal growth and differentiation of various plant explants. The course elucidates how subtle changes in media composition can dramatically impact culture outcomes.
  • Understand the complex interplay of plant growth regulators (auxins, cytokinins, gibberellins, abscisic acid) and their specific concentrations in modulating plant cell division, differentiation, and morphogenesis in vitro. This module emphasizes how hormonal cues direct developmental pathways.
  • Delve into the diverse spectrum of culture types, including callus cultures for biomass production, suspension cultures for cell studies, organ cultures for specific plant parts, and embryo, anther, or pollen cultures for genetic purity and accelerated breeding programs. Each type presents unique opportunities and challenges.
  • Unravel the distinct pathways of plant regeneration: organogenesis, which involves the formation of new shoots and roots from undifferentiated cells, and somatic embryogenesis, the development of embryo-like structures from somatic cells, offering powerful tools for clonal propagation and genetic engineering.
