  3. 3. PLANT TISSUE CULTURE Definition Tissue culture is in vitro cultivation of plant cell or tissue under aseptic and controlled environmental conditions, in liquid or on semisolid well defined nutrient medium for the production of primary and secondary metabolites or to regenerate plant. Tissue culture relies on three fundamental abilities of plant there are: Totipotency Dedifferentiation competency 3
  4. 4. Haberlandt early 1900’S • proposed concept of totipotency • cells cultured under right conditions • Callus cultured from tree cambium Gautheret, Nobecourt, Whire In the 1930s. • cells kept alive but did not develop HISTORY 4

  7. 7. Antibiotics : Stertomycin,kanamycin Activated charcoal Other organic supplements : Protein, coconut milk,yest,malt extract, orange juice, and tomato juice Growth regulators : Auxins,cytokinins Water : Demineralized or distilled water Solidifying agents : Agar, gelatin. pH adjusters : 5 - 6 it is considered to be optimum. 7
  8. 8.  PREPARATION OF CULTURE MEDIA: Stock solution 1 : MgSo4,KH2Po4,KNO3,NH4No3,CaCl2 Stock solution 2 : H3Bo3,MnSo4,ZnSo4,CuSo4,Cocl2 Stock solution 3 : FeSo4,sodium EDTA Stock solution 4 : ionositol,thiamine,pyridamine,nicotinic acid,glycine To prepare 1 liter of medium: Take 50 ml of stock solution 1 + 5ml of stock solution 2 & 4 in a beaker. The stock solution 3 prepared separately in a other 450ml flask by adding double distilled water and heat with constant stirring. Mix two solutions and adjust PH to 5.5. 8
  9. 9.  STERILISATION OF MEDIA •The prepared media should be sterilized by ISI mark Autoclave( for large amounts) at 121º Domestic pressure cookers( for small amounts) •For the sterilization of glassware and metallic equipments Hot air oven with adjustable tray is required. 9Incubator Hot air oven
  10. 10.  BASIC REQUIREMENT FOR A TISSUE CULTURE LABORATORY For the successful achievement, the following general basic facilities are required:  Equipment & apparatus  Washing and storage facilities  Media preparation room  Sterilization room  Aseptic chamber for culture  Culture rooms or incubators fully equipped with temperature, light and humidity control devices  Observation or recording area well equipped with computer for data processing 10
  11. 11. 11 TISSUE CULTURE LABORATORY
  12. 12. 12 EQUIPMENT & APPARATUS  VESSELS & GLASS WARE : • All the glassware should be of Pyrex. • Large test tubes,flasks,graduated pipettes etc.. are used.  EQUIPMENT : • Scissors,scapels,foreceps are used for explants preparation. • A spirit burner for flame sterilization. • Hot air oven. • A PH meter. • A BOD incubator. • Laminar air flow chamber. • A balance to weigh nutrients. • Data collection and recording room.

  15. 15.  ESTABLISHMENT OF PLANT TISSUE CULTURE In vitro culturing of plant tissue culture involves the following steps.  Collecting & sterilization of glassware tools/vessels.  Preparation of explant.  Surface sterilization of Explant.  Production of callus from explant.  Proliferation of culture.  Sub culturing of callus.  Suspension culture 15
  16. 16.  EXPLANT PREPARATION EXPLANT : It is defined as a portion of plant body, which has been taken from the plant to establish a culture • Explant may be taken from any part of the plant like root,stem,leaf,or meristematic tissue like cambium, floral parts like anthers, stamens etc.. •Age of the explant. • Homozygous plants are preferred. 16
  17. 17. 17 flower leaf
  18. 18.  SURFACE STERILISATION OF EXPLANT For surface sterilization chromic acid, Hgcl(0.11%),calcium hypochlorite, sodium hypochlorite(1-2%),alcohal(70%) are used. Process depends on the type of explant. SEED : absolute ethyl alcohol calcium hypochlorite bromine water sterile water FRUIT : ethyl alcohol sodium hypochlorite sterile water STEM : running water sodium hypochlorite sterile water LEAF : surface clean Hgcl2 sterile water dried explant
  19. 19.  PRODUCTION OF CALLUS FROM EXPLANT • Sterilized explant is transferred aseptically onto defined medium. • Transfer to BOD incubator. • Temperature (25 2 ͦ) and light is necessary for callus production. • Callus produced with in 3-8 days. 19
  20. 20.  PROLIFERATION OF CULTURE • if callus is well developed, it should cut into small pieces & transferred to another fresh medium containing hormones, which supports growth. •The medium used for production of more amount of callus is called proliferation medium. 20
  21. 21.  CALLUS GROWTH 15 DAYS 30 DAYS 50 DAYS 80 DAYS 21
  22. 22.  SUBCULTURING OF CALLUS •After sufficient growth of callus it should be periodically transferred to fresh medium to maintain viability of cells. •This subculture will be done at the interval of 4-6 weeks. •After a maximum growth transfer into a pottling soil under required condition.
  23. 23.  SUSPENSION CULTURE •It contains a uniform suspension of separate cells in a liquid medium callus liquid medium agitated continuously finally cells separated sub-culture the cells •This can be achieved by rotary shaker attached within the incubator at a rate of 50-150 rpm. 23
  24. 24.  GROWTH PROFILE OF PLANT TISSUE CULTURE They are classified as : Single cell culture Callus culture SINGLE CELL CULTURE The single cell culture exhibits various stages of growth. a) Lag phase: Tissue starts to grow. b) Exponential phase: This phase is characterized by rapid cell multiplication. c) Linear phase: The growth follows a linear pattern with respect to time 24
  25. 25. d) Progressive declaration phase: Aging of culture increase cell division decreases e) Stationary phase: No growth of cells occur Rate of production of cells = rate of their death f) Senescent phase: Cell death occurs to lack of nutrients 25
  26. 26.  IN CALLUS CULTURE a) Lag phase: In this phase cell trying to adjust the new environment condition. b) Exponential phase : By utilizing nutrients rapid multiplication occurs. c) Decline phase : Due to starvation some cells leads to decline in the callus culture. d) Stationary phase : No growth is evident, requires sub culturing. 26
  27. 27.  GROWTH DETERMINATION Methods used to determine are..  CELL NUMBER • By counting the cell number in haemocytometer under a microscope. •Suspension culture is preferable. 27
  28. 28.  PACKED CELL VOLUME •Cell suspension is transfer to graduated centrifuge. •Centrifuged at 2000 rpm for 5mints. •Cell will form pellets called biomass volume, expressed by ml-1 28
  29. 29.  FRESH CELL WEIGHT •When cells increase in number, the liquid will be turbid. •As a result optical density altered, detected by colorimeter. 29
  30. 30.  VIABLE CELL TEST •The staining method such as fluorescein di-acetate is used for accessing the cell viability. •Dead cells appear as fluorescein red. 30
  31. 31.  TYPES OF CULTURE Callus culture Suspension culture Root tip culture Leaf or leaf primordial culture Shoot tip culture Complete flower culture Anther & pollen culture Ovule & embryo culture Protoplast culture 31
