BIO 608 BIOCHEMISTRY OF BIOTIC AND ABIOTIC STRESSES                                                                               (3L+0P) II

Objective
  To provide knowledge about the biochemical basis of biotic and abiotic stresses in plants.

Theory

UNIT I
  Plant- pathogen interaction and disease development, changes in metabolism of  cell wall composition and vascular transport in diseased plants, Expression, structure and activity of gene products caused by genetic mutation, epigenetic phenomena and environmental agents leading to diseases.

UNIT II
  Plant defense response, antimicrobial molecules, hypersensitive response and cell death, systemic and acquired resistance, pathogen derived resistance, antipathogenic principles.

UNIT III
  Plant viruses, host virus interactions, disease induction, virus movement and host range determination; viroids.

UNIT IV
  Biochemical basis of abiotic stresses namely: drought, salinity, temperature, heavy metals, and water pollutants, synthesis and function of proline and glycine betaine, stress tolerance, stress adaptation, interaction between biotic and abiotic stresses.

UNIT V
  Reactive oxygen species, antioxidants, enzymes of defense system. Molecular strategies for imparting tolerance against biotic and abiotic stresses.
