Listening to the content while ignoring whatever annoys you about the delivery is a good skill to cultivate, and you owe it to your intellect.

No easy answers but differences between lab and field should not be seen as failure but motivate further inquiry and allow complementary discovery.

- This work started nearly 10 years ago and was once my main postdoctoral project at @plantevolution.bsky.social before I slowed work on it to a trickle because it became confusing. But it always remained extremely interesting. journals.plos.org/plosbiology/...
- A common and natural allele of the conserved gene ACD6 in Arabidopsis gave plants anti-disease superpowers in lab tests, but made them small. A growth-defense tradeoff. As someone with skills in microbiome science, I wanted to see exactly which microbes would be affected in true field conditions.
- But the always-robust phenotype vanished in field conditions, and so did the easy project. Vanished visually and molecularly. And there were no microbiome differences in the field between plants with this hyperactive allele and a standard one.

- Working with data from a collaborator who sent DNA to the Genewiz / Azenta 16S-EZ service. The company prepares amplicons and sequences. It is horrible! 1) All the amplicons all start in a different place. It seems they use some kind of cocktail of primers to amplify V3 + V4 variable regions. 1/4
- 2) They provide some stock analysis including a list of OTUs in the data.. these vary much more widely in length than 16S data, include some strange seqs that aren't 16S genes. For example, OTU2 in a plant microbiome 16S dataset is a perfect match to human "FKRP fukutin related protein". 2/4
- 3) Because of the length differences, even for the same template sequence, the data can't be directly clustered. They need to be trimmed. But Genewiz will not provide ANY information about the primers they use "because it's proprietary". 3/4
- Did anybody else use that service? In the >15 years I've worked with 16S data, I've never come across data more bizarre. The absolute lack of customer support regarding their bizarre primers is outrageous. From this experience, I cannot recommend that service in any way.
