Positive control: M. capitata sample from Holobiont Integration M2410 from well B1 from dilution plate 2.
Negative control: Ultrapure water

Initially we were worried about the difference in band size between KW and AH/ES samples (KW appears to be closer to 400 bp and AH/ES bands seem to be closer to 300 bp long). This could be because AH and ES samples are picking up more of the 18S and mitochondria regions than the 16S regions. However, the positive control was a sample that we have sequenced previously and in the gel image above it looks like the M. capitata ES samples.

Positive control M2410 sequencing details

M2410 = HPW060 (Sequencing ID with URI GSC)

Denoising stats: M2410 was the 57th lowest # of reads after filtering out non-chimeric out of 262 samples.

Next steps could be to try a short run with more of the samples from Holobiont Integration - because I only did one of my pervious ones, I don’t know if the faint band is truly reflective of the below average denoising statistics above. We decided to move forward with the protocol as is.

Bacteria / Total:

  • M2410: 64.11% of reads are bacteria (12,612 out of 19,673 reads)
  • Average sample: 56.12% reads are bacteria

Chloroplast / Total:

  • M2410: 340 reads are chloroplast (1.73%)
  • Average sample: 2.62% reads are chloroplast

Re-did the gel for some samples from plate 2. These look OK. Ready to submit all of the above samples.

We choose the code WSH (Wong Strand Huffmyer)001 - 096 for the first plate, 101-196 for the second plate, and 201-296 for the third plate.
