List The Steps of Preparation of stained Temporary Mount-Plant Care

PREPARATION OF TEMPORARY MOUNT:
Temporary mount of diseased specimen is frequently required for microscopic examination. Such mounts can be made as follows:

Take a clean slide and cover slip.

Place a drop of water on the slide.

Now add the specimen which needs to be examined. Care must be taken that the specimen should not be of large size. Size of specimen should be in few millimeters so that it could easily settle down in drop of water.

In many cases it may be necessary to tease the specimen with dissecting needle so that it spreads uniformly in a thin layer and does not form a clamp which will hamper the observation.

Then the cover slip is placed on the slide. To avoid the air bubble in mount it is necessary to place the cover slip carefully. First place the one edge of cover slip in contact with water then with the help of dissecting needle gently and slowly lower the cover slip.

Instead of water, lectophenol can also be used for mount preparation but in this case specimen should be stained with cotton blue.

Preparation of Media For Culture-PDA, PDB & NA Recipes

PREPARATION OF MEDIA FOR CULTURE: Media play an important role not only for the nutrition and growth of the pathogen but also in identification through growth pattern on media. Fungi and Bacteria need synthetic media enriched with essential element for the growth. In general different types of media are prepared to culture fungi and bacteria but Potato dextrose agar (PDA) for fungi and Nutrient agar for bacteria are being used commonly. RECIPES OF DIFFERENT MEDIA: POTATO DEXTROSE AGAR: Potato Starch 250 mL/15g Dextrose-15g Agar -Agar 15g Distilled water 750 mL/1000mL PROCEDURE TO PREPARE POTATO DEXTROSE AGAR MATERIAL: Petri dish, Flask, test tubes, Agar-agar, Dextrose, Potato starch, Water PROCEDURE: First of all take potatoes to extract potato starch. Peel the potatoes and cut into small pieces. Preferably 200 g of potato pieces are weighed, washed quickly in running water, placed in 1l liter of water and boiled for nearly

GEL Procedure Of Gel Electrophoresis For Separation DNA/RNA

GEL Procedure Of Gel Electrophoresis For Separation-DNA/RNA GEL ELECTROPHORESIS GEL Procedure Of Gel Electrophoresis For Separation-DNA/RNA Mix 1 g agarose in 99mL of TAE/TBE buffer and heat it in the oven. Add 10 uL of 10mg/mL ethidium bromide in 100 mL of hand cold agarose gel solution. Pour this mixture into gel caster/tray having comb and sealed from sides. Let it be solidified at room temperature for 30-60 minutes. Remove the comb seals from the gel caster and place it inside the gel tank containing TAE/TBE buffer. Put the DNA samples/PCR product (mixed in 6x loading dye) inside each well and note it in the lab. Notebook. Attach the cathode (towards wells) end of gel and anode (at the bottom) of the power supply to the gel tank. Switch on the power supply giving 80-120 volts and run it for sufficient time allowing the samples to travel in more than half of the gel length. Take the gel out of the gel tank and observe it in a gel doc system/UV transillumin

Total Plant RNA Isolation-Trizol Reagent Method

Total Plant RNA Isolation Using Trizol Reagent 1. Crush 100 mg of tissues in 1mL of triazole reagent by pestle mortar or micro pestle 1.5 or 2.0 mL RNase free Eppendorf tubes. *Incubate for 2-3 minutes at room temperature. 2. Add 200 uL chloroform and mix by gently inverting the tube. *Incubate for 2-3 minutes at room temperature. 3. Centrifuge at 12000xg at 4oC for 15 minutes. 4. Transfer the supernatant into fresh 1.5 mL RNA’s free tube. 5. Add 500 μL isopropanol mix gently by inverting the tube. *Incubate for 10 minutes at room temperature. 6. Centrifuge at 12000xg at 4oC for 10 minutes. *Discard the supernatant and keep the pallet in the tube. 7. Add 1mL of ice-chilled 75% ethanol to wash the pallet. 8. Centrifuge at 7500xg at 4oC for 5 minutes. *Discard the supernatant and keep the pallet in the tube. *Keep lid opened tube at 4oC for 15 min to air dry the pallet. 9. Add 50-100 uL RNA’s free water in pallet and mix by gentle pipetting. 10. Incubate for 10-15 m
