Planting on Plates

Make MS plates

  • To get weakling mutants started before potting in soil
  • Or to plant seeds on specified media
  • Or to see roots

Seed Preparation

Seeds must be sterilized before they are put on sterile plates.

After sterilization,

  • Make a line of seeds in agarose above the midline of the plate, either
    • either on the agar directly
    • on flattened cellophane
  • Tape plates shut with Micropore surgical tape
  • Stack plates flat
  • Refrigerate the plates for 2 days in the dark
  • Move plates to growth chamber
  • Stand plates on edge under the lights. Tape several together.

0.1% agarose for plating seeds

  • 100 mL sterile ddH2O
  • 0.1 g agarose . autoclave to melt; shake bottle after autoclaving

Sterilize seeds with EtOH & Tritonx

Sterilize seeds with EtOH & Tritonx kdorfman Mon, 02/14/2022 - 18:31

  • sterilize seeds in a solution of

    • 0.5 mL 70% EtOH,
    • 0.05% TritonX-100,
    • ~3 min mild agitation.

  • Let seeds settle, remove liquid

  • Replace with sterile water, 3X

  • Replace water with sterile 0.1% agar, 3X

  • Plate in a line, either

    • directly on agar, one seed per tiny drop or
    • on flattened cellophane (wet it if necessary)

  • Wrap plates with micropore tape

  • stack plates flat

  • cover in foil, refrigerate, 48 hours

Sterilize seeds with EtOH then dry

Sterilize seeds with EtOH then dry kdorfman Mon, 02/14/2022 - 18:39

  • Put appropriate number of seeds in a sterile microfuge tube

  • Sterilize filter paper with EtOH, let dry in sterile hood (can set it on top of an open sterile petri plate cover

  • Add 95% EtOH to seeds for 5 min, dump seeds onto filter paper

  • let dry, tap onto agar of an MS plate

Sterilize seeds with bleach

Sterilize seeds with bleach kdorfman Mon, 02/14/2022 - 18:37
  • Add ~1mL of bleach solution to each tube
  • Cap and shake
  • Leave tube on its side for 20-30 min, shaking periodically
  • Put upright after last shake (so seeds settle)
  • In laminar flow hood
    • Use a pipetman that has been sprayed with ethanol and air-dried in the hood
    • Remove as much bleach solution as possible from the tube
    • Add ~1 mL sterile ddH2O, mix and let seeds settle again
    • Do at least 4 washes, to dilute out the bleach
    • Add ~1mL sterile 0.1% agarose (so seeds will be suspended in the liquid)

Bleach solution for sterilizing seeds

  • 7 mL sterile ddH2O (must be freshly made!)
  • 3 mL Chlorox
  • 1 uL Triton X-100 (detergent to help get bleach into seed crevices)

0.1% agarose for plating seeds

  • 100 mL sterile ddH2O
  • 0.1 g agarose . autoclave to melt; shake bottle after autoclaving

Arabidopsis planting guide - Plants on soil

Routine weekly planting to produce plant material for observation or DNA extraction

  • Pots
    • 6 pots in a big flat with no holes
    • fill with clump-free potting soil, leaving some space at the rim
  • Treat with Gnatrol for fungus gnats
    • saturate with hot water the night before Teddi comes
    • Arrange for Teddi to do Gnatrol treatment
  • OR Heat in oven
    • pre-heat oven to 225F (=~107C)
    • Put soil-filled pots in aluminum lasagne pan
    • Cover with foil
    • insert thermometer in one pot near center
    • Heat to 180F (=~82C)
    • leave in oven for 30 min.
    • leave covered until ready to plant
  • Seeds for DNA
    • Start a set 4 weeks before needed, another set 3 weeks before
    • Columbia wild type (col-0)
    • Scatter seeds on surface of soil (remoisten before if it is dry)
    • Put on plastic cover
    • Put in refrigerator, keep dark (this synchronizes germination)
    • Transfer to growth chamber on the third day
    • If no room in fridge, put seeds in microfuge tube, add water, refrigerate in dark 2 days, then plant
  • Seeds for demo or experimental plants
    • Put seeds in microfuge tube, water, refrigerate, keep dark
    • 3rd day: pour into small beaker, add more water
    • Deposit one seed to each corner of the pot, plus one in the middle with a transfer pipet.
    • Transfer to growth chamber
  • Growth Chamber
    • 22C, 16H light, schedule continuous program
    • Water bottom flat ~3x per week
    • Remove cover after plants are well established.

*Making cDNA +Fe & -Fe roots and shoots**

20 MS plates, heavily sown with At Col0 seeds.

At 7 days, transplant all seedlings, half to MS plates, half to –Fe plates.

After 3 more days, harvest roots, shoots. 12 samples in all.

(In future, plant 4 full plates per root sample)

Use razor blade to amputate roots

Grind in ceramic mortar and pestle (bake 1st overnight!)

Extract RNA, following lab manual protocol.

From 5/7/10:

S-3 79.05 2.53 0.56 4.44

max ng in most dilute sample= 44.50

Can’t get 200 ng RNA in less than 5 µL in several samples.

Calculate the amount of RNA in 5 µL of the most dilute sample (-R2), calculate the µL of each sample required to get that amount. Add water to 5 µL.

Run on gel. R-3 was calculated wrong (or it degraded).

Initial spec reading was 6.3; reblanked and got 18. Maybe the 6.3 was right?

Gel:

Lane 1 2 3 4 5 6 7 8 9 10 11 12 13
HMW std R+1 R+2 R+3 S+1 S+2 S+3 R-1 R-2 R-3 S-1 S-2 S-3

Freeze the RNA.

Two choices for cDNA:
* omit R-3 (calculate amount of RNA from next most dilute, -R 2), * or recalculate R-3 from the initial 6.3 reading

From –R2: 11 µL contains 97.9 ng of RNA, almost 10% of the recommended amount.

Can run 11 RTPCR reactions, and only have 40 µL of R- samples, but 60 µL of all of the others.

From –R3 at 6.3ng/µL: 11 µL contains 69.3 ng, which is only 7% of the recommended amount.

Combine the 3 of each type into a single tube. Measure volume:

sterilize seeds

sterilize seeds kdorfman Fri, 05/24/2013 - 18:33

  • sterilize seeds in 0.5 mL 70% EtOH, 0.05% TritonX-100, ~3 min, mild agitation.

  • Let seeds settle, remove liquid

  • Replace with sterile water, 3X

  • Replace water with sterile 0.1% agar, 3X

  • plate heavily in a line on flattened cellophane (wet it if necessary)

  • stack plates flat

  • cover in foil, refrigerate, 48 hours

test platforms

test platforms kdorfman Fri, 05/24/2013 - 18:38

Try different porous platforms for seedling growth

Get samples from Magdalena's lab

Sterilize between sheets of filter paper in a glass petri dish.

  • Moss cellophane

  • Roll cellophane

  • Magenta box screen

  • Sheer fabric

Seeds grow fine on flat cellophane. The roots have trouble getting over a bump or air bubble.

Seeds do not grow well on mesh fabric.

Wire screen does not lie flat on agar.

Put samples of each on MS agar

Iron experiment

Iron experiment kdorfman Fri, 05/24/2013 - 18:46

Grow Col0 seeds to test effect of iron deprivation on gene expression

Make plates:

Sow sterile seeds on cellophane in 12 MS plates as heavily as possible.

After stratification,

  • 7 days in incubator

  • Transfer half to iron-free plates, half to MS plates

  • Harvest after 3 days

Grind tissue

Grind tissue kdorfman Fri, 05/24/2013 - 19:13

Grind roots +/-, shoots +/- in ball mill (Sam's Retch Mixer Mill MM400)

  • Precool the white block for the ball mill

  • prepare 2 2-mL tubes per plate (label tubes on side as well as top)

    • 3 roots + iron
    • 3 roots - iron
    • 3 shoots + iron
    • 3 shoots - iron

  • 2 metal beads per tube 3.2mm diameter ss beads (90g) - Cat. No. 11079132ss from www.biospec.com (Can also get from Fisher)

  • cool in LN2

  • Add tissue to cold tube, put back in LN2

  • Put all tubes in cold block

  • Shake 20 sec, check. The heat of shaking may start to defrost the tissue. Throw it back in the LN2. (Shake too long, and the cap may disintegrate!

  • Return to LN2

[RNA] by nano-drop

[RNA] by nano-drop kdorfman Fri, 05/24/2013 - 19:00
  1. Clean the pedestals

  2. Blank the machine

    1 µL buffer onto lower measurement pedestal

    F3 (Blank)

  3. Wipe again

  4. Test the blank:

    1 µL buffer

    F1 (Measure)

    if it's flat, you're good to go

  5. 1 µL sample. repeat.

RT

RT kdorfman Fri, 05/24/2013 - 18:50

Make cDNA by reverse transcription

Calculate the volume of each sample required to get 1 µg RNA

For reactions
with ng/µL RNA
add: µL oligo(dT)
add: µL RNA
add: µL 10mM dNTP mix
add µL water (final vol = 13µL/rxn) 65 C 1 min, then ice. Spin down.
add: µL 5X 1st strand buffer
add: µL 0.1M DTT
add: µL RNAseOUT
add: µL Superscript III (200U/µL). 50C 45 min. Stop rxn: 70C 15 min

Note I bought the 10 µL Superscript, mixed it with some leftover, and had enough to do one reaction per RNA sample (=60 µL per treatment). Should have bought the bigger size.

I should use some of the remaining RNA to try out the RT sample I got from Qiagen. Maybe the best 8 RNA's.
