This is the paper Chris is talking about, I just don't know how to post a .pdf file   http://link.springer.com/article/10.1023/A:1022986615694

  It`s a very good question. I don`t know if there are any feedback loops, but I`d be very surprised if there weren`t. Allosteric hinderance is more a spatial thing, where the binding of something to something else prevents access to that binding site. That`s one way that feedback loops can...

Only a tiny proportion of the Valine/Phenylalanine are funnelled into this pathway, so on a plant-wide scale it`s not important. If you mess up specific amino acid biosynthesis, then yes, you could kill the plant, assuming it isn`t getting them from exogenous sources, such as fungi or bacteria...

  Yes, I did. Biochemistry, Cell Biology and Genetics. 20+ years of Cancer Research.

  That`s all absolutely right. In practice, biosynthetic pathways have extra control steps built in, too. Things like turning enzymes on or off at a specific stage. Most also have what is called a rate-limiting step. That`s one step that is like a bottleneck. The size of the bottle neck...

Many Capsicum traits are already liked to specific genes. The classic example is the PUN1 gene (pungency 1). Cultivated Capsicums with no heat almost always have a deletion in that gene, making the gene product unable to function and the plants unable to make capsaicin. Here is an older...

  You can get it done for plants relatively inexpensively these days. There are numerous places, below is just one I picked at random. Costs are basically associated with tissue preparation, which in plants is a bit more tricky, but the rest is identical to testing any DNA. Market forces dictate...

  C.chacoense are a pain to eat, because of the seeds. Not easy to de-seed either, as they aren`t really worth the effort. Tepins and Donne Sali are nowhere near as bitter, to me anyway. Donne Sali are extremely fruity and the flesh is very soft; surprisingly hot, as well. Wonderful variety.

I know a lot of growers in the UK and I`ve yet to see anyone growing that. Another Jon Harper cross, like the Borg 9 and Bubblegum 7-pot. Let me ask a few folks.   OK, asked a couple of people in the UK and they`ve not seen it being grown, either. 

Depends on how many generations you want to grow out. You can enrich a population for a certain phenotype over time, if you select for the desired phenotype at every generation. Over numerous generations you will enrich for that phenotype, but it is a similar prospect to making a new hybrid...

Cappuccino Tepins - hunted down by Chris Phillips and seeds are from wild collected pods (there`s red and yellow too, from the same source). For those of you on Facebook it`s from "Chiltepines de la Sierra" in Mexico.   I`ll avoid the wilds and those mentioned so far, although I agree with all...

Just a quick note about Chris. He`s being guided towards a possible bone marrow transplant in the next month or two.   I`d just like to say that everyone has been incredible with donations and support, but that he still needs us. A transplant runs roughly half a million dollars and while Chris...

"Originally developed by our head horticulturist Steve Bender, the California Reaper is a cross between the Carolina Reaper and the Peach Ghost Scorpion. Dr. Bender has spent numerous grow seasons developing the California Reaper, which is essentially a peach version of the Carolina Reaper."  ...

  If you mean the original crosses, no I don`t. If you mean any potential unintentional crosses, that`s a no as well. Sorry.

Been there with pets and all sorts of plants. It sucks. A LOT, but the fun and love I get from our pets far exceeds anything a plant can give me. I do feel your pain, though!

OK, these are purely my opinions and I make no claims that they represent anything other than that.      Aji Mango (PL) - - - - - - - - Not tried these yet Bhut Jolokia Indian Carbon - - - - One of the hottest versions of the Red Bhut I`ve ever grown. Try the Burmese Naga instead, better flavour...

There is a new White Bhut that I think only Jim Duffy has for 2016 (there`s an Orange one, too). It originally came from the Weaver family in PA, as in Jay`s Red or Peach Ghost Scorpion or his Father, Jim, with Lightening Habaneros.    It looks like a Bhut, tastes like a dilute red Bhut is...

An update on Chris.   He started round 2 chemotherapy last Friday and on Sunday started taking a new drug known as a Tyrosine Kinase Inhibitor (TKI), in this case Dasatinib. This is because Chris' Leukemia is driven by a chromosomal translocation. A chunk of chromosome 22 accidentally got put on...

  It should be the same, yes. If you are unsure PM me.   The fees are the ones for using a credit or debit card that are paid on every transaction, usually by the person or business that accepts the card. In this case there is no accepting business, so the donator pays the fees incurred either...

I grew Genghis Khan`s Brain and Apocalypse in 2015, seeds direct from AIASP in Italy. Both are F6, I think. However, both also gave very variable results in terms of phenotypes. I know 20-30 people who grew them both and they were all over the place. A few actually got purple plants for...
