Sanger sequencing preps for Moorea 2023 project at URI

During my visit to URI this past week I processed DNA for Sanger sequencing for species identification. These samples are from the 2023 Moorea Symbiotic Exchange project. In this project, I collected corals of three genera (Acropora, Pocillopora, Porites) including adults and recruits. We used Sanger sequencing and RFLP to identify species within these genera.

Overview

gDNA extractions were completed by Pierrick in October 2024.

My samples were included on Plate 38, 39, 40, and 41 of extractions. Sample metadata is on GitHub here.

Protocols used

Sequencing metadata sheets and all images of gels and associated data is on my GitHub here.

Pocillopora

To identify cryptic species in Pocillopora we use mtORF sequencing as described in Johnston et al. 2018 and Burgess et al. 2024. Our protocol for this is described here.

mtORF sequencing identifies haplotypes. For haplotype 1a (grandis/meandrina complex), we then conduct an RFLP analysis as described in Johnston et al. 2018 to distinguish between these two species. This week I finished up preparing samples for sequencing and ran an RFLP.

mtORF sequencing

Today I prepared the following samples for mtORF sequencing. These were previously extracted by Pierrick, amplified for mtORF, and the PCR product was cleaned. The plate maps and gels for these samples can be found on GitHub here.

  • All plate 39 Huffmyer Pocillopora samples: Wells A1-C8
  • Samples in wells F2, F5, F8, F11, and H11 in plate 38 that failed sequencing in a previous run

I’ll post another notebook post detailing sequencing analyses.

Protocol:

  1. Dilute forward primer (FatP6.1) to 3.2 uM by adding 33.3 uL of 10 uM primer to 66.6 uL of nuclease-free water
  2. Add 8 uL of water to each strip tube for samples
  3. Add 2 uL of sample clean PCR product to respective tube
  4. Add 2 uL of F primer at 3.2 uM to each tube

Sample information is as follows for samples labeled with “Project 1” for sequencer.

These were dropped off for sequencing on 20241120 by Hollie.

Poc Histone RFLP

20241117

I performed an RFLP using the protocol linked above for all Pocillopora samples. I decided to run all samples before all have been sequenced because I will not have enough time to get back sequences and analyze before I leave URI. By performing RFLP on all samples, I will have the RFLP data to reference after analyzing sequences and will not require someone to run the RFLP for me later.

I ran the RFLP on 81 total samples.

I prepared the master mix.

Component 1 rxn 100 rxns
EmeraldAmp 2X TT master mix 12.55uL 1255ul
POC Histone F primer (10uM) 0.32uL 32uL
POC Histone R primer (10uM) 0.32uL 32uL
Ultrapure H20 10.8uL 1080uL
Template DNA 1uL  
  25uL 23.99uL

I ran all reactions in a 96 well PCR plate. Added 24 uL of master mix to each well. Then added 1 uL of template DNA of each sample. 1uL of water was used in one well as a control.

I used a positive control as sample #159 from Hollie. There was very little DNA left in the tube.

The PCR protocol was as follows:

  • 94°C for 60 sec [1 cycle]
  • 94°C for 30 sec, 53°C for 30 sec, 72°C for 60 sec [30 cycles]
  • 72°C for 5 min [1 cycle]
  • Hold at 4°C

After PCR, samples were stored in the fridge overnight.

The plate map is included below. Note that the sample ID’s in this plate map are the well numbers of the gDNA from the original gDNA plate. The plate map for gDNA (below) will have the tube ID for this project.

After PCR for POC Histone, I ran the restriction enzyme incubation for the RFLP. I generated a master mix containing rCutSmart Buffer (1.9 uL per reaction) and XholRE (1.9 uL per reaction) with 15 uL of PCR product in each reaction.

I added the enzymes and sample to each well with 15 uL of water added to a new negative control (NEG2).

Samples were incubated at 37°C for 1 hr then at 65°C for 20 minutes with a 10°C hold in a thermocycler.

Samples were loaded in the same positions as the PCR plate. Sample ID in the plate maps indicates the well from the original gDNA plate.

I then looked at the PCR product on a gel after the enzyme incubation. If there is a cut, the sample is P. grandis and if the enzyme does not cut, the sample is P. meandrina. We are only going to use this to look at samples where the mtORF sequence analysis indicates that the sample is in haplotype 1a (grandis/meandrina complex) as described in linked protocols and papers above.

I ran 2% gels for 90 min at 80V to view the results. I ran this with 3 gels to fit all samples.

RFLP gel 1

RFLP gel 2

RFLP gel 3

There are some samples that cut very clearly and negative controls have no bands. The positive control did not show up, which is not surprising because of the very low DNA available in the original tube. There are also some higher bands in some samples. The variation in banding pattern may not be surprising because we ran this on all samples, which may contain several Pocillopora species and not just P. meandrina and P. grandis, as it was designed for.

We will use these results to look for the cut bands for samples identified at haplotype 1a when sequence data is returned. The RFLP bands will not be used to identify species other than grandis/meandrina.

The enzyme did successfully cut and for samples we had preliminary sequences for, it did cut only those identified as haplotype 1a.

Porites

H2-H4 sequencing

20241117

Hollie prepared the Porites H2-H4 PCR for all Porites samples using the protocol linked above. The gDNA for these samples came from plates 40-41 of gDNA extractions.

gDNA plate map 40 41

We PCR’d samples from Plate 40 B6-H12 and 41 A1-A2 for 81 total samples.

Component 1 rxn 90 rxns
EmeraldAmp 2X TT master mix 12.6uL 1134ul
zH2AH4f F primer (10uM) 0.3uL 27uL
zH2FrR R primer (10uM) 0.3uL 27uL
Ultrapure H20 10.8uL 972uL
Template DNA 1uL  
  25uL 23.99uL

The PCR protocol was as follows:

  • 96°C for 120 sec [1 cycle]
  • 96°C for 20 sec, 58.5°C for 20 sec, 72°C for 90 sec, 72°C for 90 sec [34 cycles]
  • 72°C for 5 min [1 cycle]
  • Hold at 4°C

We used a negative control of water only and used a positive control of a P. evermanni sample (JA 491 9/25/24).

Samples held overnight on the thermocycler at 4°C. We will run a gel in the morning.

The plate map sample ID refers to the tube ID, which is also what is recorded in the gDNA plate maps above.

POR H2 plate map

20241118

I ran a gel to look at the PCR product. I ran a 1.5% gel at 80V for 90 min with 3uL of sample. I also added a 1Kb ladder. I ran three gels to fit all samples.

POR H2 gel 1

POR H2 gel 2

POR H2 gel 3

Notes from gel results:

  • Wells A1, A2, A9-A12 had no bands
  • All other samples have a clear band
  • No bands in negative control
  • Postive control has a clear band

I then looked at the gDNA data and some of the samples had >10 ng/uL DNA concentrations, which is about twice of that of samples that amplified well. I then decided to re-amplify the samples that failed with half of the template DNA, because the DNA concentration may have been too high for this PCR reaction.

I therefore did another round of PCR for the failed samples with 1/2 of the DNA volume (0.5 uL of DNA and 0.5 uL of water in each reaction).

Component 1 rxn 10 rxns
EmeraldAmp 2X TT master mix 12.55uL 125.54ul
zH2AH4f F primer (10uM) 0.32uL 3.2uL
zH2FrR R primer (10uM) 0.32uL 3.2uL
Ultrapure H20 11.3uL 113uL
Template DNA 0.5uL  
  25uL 23.99uL

I used sample #75, which was a sample that successfully amplified yesterday as a postive control. Water was used as a negative control.

If these successfully amplify, they will replace the failed sample wells in the PCR product plate to submit for sequencing.

Ran in strip tubes labeled with tube ID. PCR ran as described above and I’ll run a gel in the morning.

20241119

I ran a 1.5% gel at 80V for 90min with 4uL of sample to check PCR product from samples that were re-done yesterday. There are 6 samples and 1 positive control, with 1 negative control.

POR H2 re do gel

All samples have bands - reducing DNA input worked! Positive control amplified and negative controls have no band.

We can now proceed with cleaning and preparation for sequencing for all Porites samples.

I then performed a clean up using the Zymo Zr-96 DNA clean up kit in a 96-well plate format. Note that during this process I removed the failed samples from the first round of PCR and replaced with the successful PCR product for those samples.

  1. Add 100 uL DNA binding buffer to PCR samples, mix, and transfer to silicon A plate on top of column plate.
  2. Centrifuge at 3000g for 5 min.
  3. Add 300 uL of DNA wash buffer (100% ethanol added to buffer by HP) to each well.
  4. Centrifugure at 3000g for 5 min.
  5. Add 300 uL of DNA wash buffer again to each well.
  6. Centrifugure at 3000g for 5 min.
  7. Add 40uL nuclease free water to each well.
  8. Transfer the silicon A plate to the elution plate.
  9. Centrifuge at 3000g for 3 min.
  10. DNA is now in the elution plate.
  11. Store at -20°C until sending for sequencing.
  12. Discard of waste in hood.

I then assembled boxes for each of the projects for sequencing. Project 1 is the Pocillopora mtORF samples as described above. Project 2 is the Porites H2 samples. To prepare for sequencing, I added the plate of clean DNA to a labeled box and added in a tube of 3.2 uM primers. We decided to sequence both the forward and reverse due to the length of the sequence desired.

Sample information is as follows for sequencing. Sample name is a running number for Janet and the Sample Name includes the actual tube ID that I will use to track to sample.

20241119

Hollie and I talked about primers to use for Acropora species identification. Hollie previously tested some of the primers from the literature. We already have primers in the lab for PaxC (PaxC_intron_FP1 forward and PaxC_intron_RP1 reverse) and CRf/CO3r (CRF forward and CO3r reverse) so we will try those first.

PaxC_intron:

CRf/CO3r:

  • Mitochondrial putative control (933+ bp) + 83 bp of cytochrome oxidase III as in Vollmer et al. 2002

CRf/CO3r sequencing and PaxC_intron_FP1/PaxC_intron_RP1 sequencing

I prepared two PCR plates - one for each primer set.

CRf/CO3r:

Component 1 rxn 95 rxns
EmeraldAmp 2X TT master mix 12.55uL 1192.25ul
Ultrapure H20 10.80uL 1026uL
CRf primer (10uM) 0.32uL 30.4uL
CO3r primer (10uM) 0.32uL 30.4uL
Template DNA 1uL  
  25uL 23.99uL

PaxC:

Component 1 rxn 95 rxns
EmeraldAmp 2X TT master mix 12.55uL 1192.25ul
Ultrapure H20 10.80uL 1026uL
PaxC FP1 primer (10uM) 0.32uL 30.4uL
PaxC RP1 primer (10uM) 0.32uL 30.4uL
Template DNA 1uL  
  25uL 23.99uL

I used a Becker Heatwave Acropora pulchra as a postive control (no. 24 gDNA from 10/29/23). Water was used as a negative control in both plates.

The plate maps for these PCRs shows the sample ID as the well from the original gDNA plates.

The gDNA plates are as follows.

The PCR protocol (“acro” on Putnam account) was the same for both primers.

  • 95°C for 3 min [1 cycle]
  • 94°C for 30 sec, 53°C for 30 sec, 72°C for 1 min [35 cycles] melting temperature chosen based on lowest primer melting temperature
  • 72°C for 5 min
  • Hold at 4°C

Images of primer labels can be found on GitHub here.

I then ran a gel for the CRf/CO3r primer set. I’ll run the PaxC gel in the morning.

I ran PCR product on a 2% gel for 90 min at 80V.

The gel product looks really nice. No bands in the negative controls, a band in the positive control. There are bands present for all other samples. Sample AH229 had a faint band - but this is ok because it was an accidental Pocillopora sample that was included! All other samples look good.

Notes from the gel results:

  • Very interesting! The bands all have varying lengths. It will be interesting to see if band length corresponds with species after sequencing analyses.
  • Negative controls have no bad, the positive control as a band.
  • Interestingly, the Pocillopora sample amplified well (we won’t be analyzing this sample since it was an accidental inclusion).

All samples look good, we will move forward with cleaning and sample preps.

I cleaned the plates following the same protocol as above for Porites samples. Sample plates were labeled and stored in the freezer with one plate for each primer set.

We will sequence both the forward and reverse for the CRf/CO3r primer set and only the forward for the PaxC (smaller length).

Sample info is as follows.

Hollie dropped these off for sequencing.

Next steps

Next, I will analyze sequences to determine species ID and then decide how to proceed with sample processing for RNA and/or metabolomics.
