NEMA 601 ADVANCES IN NEMATODES SYSTEMATICS                                                                                 (2L+1P) II

Objective
  Apprising of ultrastructural, cytogenetical, biochemical and molecular approaches in nematode systematics using SEM and TEM.

Theory

UNIT I
  Importance of ultrastructure of nematode body wall- cuticle, hypodermis and muscles; nematode feeding apparatus, and other parts of alimentary canal in nematode systematics.

UNIT II
  Importance of ultrastructure of  nematode sense organs, reproductive and excretory secretory systems in nematode systematics.

UNIT III
  Preparation of illustrations, keys and compendia for nematode species and other taxa.

UNIT IV
  Recent advances in nematode identification- molecular, biochemical, immunodiagnostic, molecular characterization and DNA finger-printing techniques.

UNIT V
  Databases and computer aided nematode identification programmes - NEMISYS (NEmatode Identification SYStem), NEMAID etc.

Practicals
  Detailed studies of morphological structures and identification of plant parasitic nematodes up to species level. Drawing and measurements of nematodes, preparation of compendia and keys. Identification of species/races of root-knot and cyst nematodes using PAGE.
