Dogs, Horses and Gardening, with a side of research on complexity and metabolic warfare in plants
There are lots of answers out there that are beautiful because the truth of the system is beautiful. If I find one of these beautiful facts, it doesn’t make me brilliant. Just right place and right time. True scientific heroes acknowledge that fact.

How many other people teaching Genetics go into how Mendelian genetics concepts do not need DNA to be true?

Or how Mendelian genetics does not inherently make causal arguments?

Or how polygenic traits follow Mendelian rules?

Enzyme/GO overlap note of the week.

Plant Glutathione-S-transferases might have more biosynthetic functions than ROS detoxification functions.

Also, CYP450s are listed as redox genes but are almost all biosynthetic.

So if you see ROS/Redox terms, take a glance to make sure it isn't biosynthesis.

I wonder how Ross Douthat from @nytimes.com is thinking his oped on current foreign policy success is aging? After only a week.

In plant-pathogen or plant-microbe interactions what is the proper null.

- there is specific coevolution of any pathogen/microbe such that it was at least partly adapted to the host isolated.

-the host of isolation may have not effected the pathogen in the slightest.

Why can’t an American brewery understand how simple is super tasty. No need for bourbon barrels, peanut butter, imperial, espresso, etc. just a solid brown/dark beer. Perfect fall yardwork break.

Admittedly the Maui coconut porter is a guilty exception.

So theoretical question, if one can shift a trait from oligo to polygenic simply by removing a large effect allele from the population, is there a real difference or is it just human desire to define?

Waiting for Ross Douthat at @nytimes.com to write an article about how the pope is wrong and that unrepentant violence and aggression against anyone is perfectly appropriate for a Catholic to support. While being pedantic about and around everything.

MPMI Terminology question - What simple phrasing would you use differentiate a plant response that happens to all members of a pathogen species versus the same plants response that is limited to one or a few pathogen genotypes in the species.

I'm thinking I should make this a weekly post -

Does anyone have good literature on a anthocyanin biosynthetic mutant having a stress sensitivity phenotype in the wild beyond UV-B?

@planteditors.bsky.social, any good suggestions on how to erase writing from ones head? I'm teaching a couple of writing classes and realizing I can't erase the previous document from my head efficiently enough to pay full attention to the next.

PS - Yes, I should not be teaching writing classes.

After having @planteditors.bsky.social look through a paper and only suggest a single wording change within the main text. Only took 24 years to get there. (Gotta love that caveat)

Host-pathogen cotranscriptome papers are really intricate to write as you have genes that are host influenced, pathogen influenced and interaction influenced in both the host and the pathogen.

Thinking of the standard senntence saying “because plants are sessile they …”. Is the direction arrow correct? Or is sessile not a cause but a consequence?

I.e. because plants are autotrophic, they are sessile.

If you were the predicting sort, how much of a plants metabolism would be in the following four categories?

Primary Anabolism
Primary Catabolism
Specialized Anabolism
Specialized Catabolism

Feel free to define "how much" by gene #, enzyme #, flux fraction, etc.

And your own 1 v 2 defn.

An interesting part of Brassica/Glucosinolate. There is so much myrosinase that the glucosinolates 1/2 life in herbivory is on the order of seconds. For any receptor signal to matter it has to cause significant effects in less time than seconds onlinelibrary.wiley.com/doi/10.1111/.... #secmet

Anyone have any literature on how yeast or other fungi detect plant phytohormones? I know they respond to them but am struggling with the search terms to find the genes that allow fungi to respond to plant compounds.

Just an outrageous amount of structural variation in pennycress. While not yet reproductively isolated, its likely these shredded pericentromeres contribute to some reproductive incompatibilities.
Whole-genome alignments revealed pennycress has nearly dichotomous genome compartmentalization: huge gene-poor pericentromeric regions (~300Mb; <1% genic) with frequent rearrangements and highly syntenic gene-rich chromosome arms (~150Mb; ~20% genic). What we call a "two-speed" genome structure. 3/
