"1 is blue" 🤣. Maybe the first black people will appear in the next slide update

yes. totally. the philosopher may have had the wrong idea at her first glance, though

I found this problem with one of them, a Microbacteriaceae. For them, gyrB and recA are reliable for taxonomy. The solution was to consider that trash data as... trash data. I chose to cite it in my discussion; I think that the proper behaviour is to honestly announce the published wrong 🤷‍♂️.

Nice to read from you, Omid. Thank you for your insights. There, I am referring to a lateral work that I am conducting. In it, I am investigating the etiology of a bacteriosis reported by farmers in Brazil. We find at least three bacteria involved in disease.

After this consideration, I still consider this sequence a putative essential enhancer.

By the way, it had become a pleasant exercise, something like a tabletop RPG on science concepts. 😅

A modern example of the social impact of plant diseases. There are reports of "improvised" experiments conducted by small farmers by themselves to find solutions. Great to see farmers trusting in science. I hope that we deal with it quickly. 🧪

Ok. Conceptually, thinking of an exon without transcription is paradoxical. It may be an AI hallucination. However, I also hypothesise that enhancers could fit as the described sequence. It may regulate gene transcription of genes very distant in the genome sequence. How about it?

I see! Let's align our presupposed: with nonfunctional exon, you mean an ORF (with promoters, terminators, etc.) that is confirmedly not transcribed? I am still thinking on possibilities.

Post-transcriptionally, a 5' exon could act as a regulator of downstream functional exons on a given mRNA. A second possibility is post-translational modifications in the same notion. The 5' exon could experimentally be ignored due to its nonfunctionality to the protein activity.

Let me consider: intact = no mutations over millions of years? I am thinking of different possibilities 🤔; however, nothing much specific to plants.

it would be lovely if my application competitors were like that... 😅

There’s no report of this disease, nor a description of Koch's postulates. There is just a genome sequence 🤷‍♂️. NCBI classified the sequence as contaminated and fragmented. I BLASTed gyrB and recA sequences, which match a completely different genus. So... WHAT?! How do I discuss it in my work?
