Hello, please tell me about corn genetics
maize. 
maize is so fucking weird. like i can’t even cover it in one post so i’m just gonna focus on one of the LARGEST reasons it’s so fucked up in this post so buckle in babes it’s time for a wild ride
to understand maize genetics on a fundamental level, we have to understand the work of Dr. Barbara McClintock, a brilliant botanist who dedicated her life to how fucked up corn is while simultaneously never being taken seriously because she was a woman. McClintock noticed a few things while studying maize in the early 1940s. as you might know, maize doesn’t always look all yellow; sometimes the kernels are colored differently, like this: 
Tumblr media
well yeah about that, she started noticing correlations in how the kernels were colored based on certain cases of the genes (imagine them as sections of DNA) she was looking at being rendered nonfunctional (or being “broken”).
for instance, lets say we breed a maize plant thats supposed to have only purple cobs, but when it grows up, the cobs are a different color entirely, or patterned differently, or completely different from what we were expecting. this happened a lot to McClintock. like, constantly. after testing the DNA of the plant, she would find that the reason the plant didn’t bear purple cobs was because of other genes randomly teleporting into the middle of the gene she was testing for. so our purple maize plant wouldn’t make purple cobs because some random ass shit inserted itself in the actual fucking middle of the ‘make purple pigment’ gene, causing it to ‘break’. we now know these teleporting little shits as “transposons”, and they’re a normal thing that casually happens IN ALL LIVING THINGS. but they didn’t know that in the 1940s. 
so not only did McClintock have random shit jumping into other random shit, but she had a REALLY hard time on her primary project of mapping the maize genome (the act of building a basic outline of which gene goes where on each chromosome) because it seemed like no matter what gene she was looking at, it would be in a different place in the genomes of all her plants (it should be noted that as we know them to be, many genes really are stable and stay in their same positions consistently through a species. for instance, lets say that there’s a gene on your 5th chromosome that codes for eye color. although your eye color may be different than the person next to you, their eye color gene is still located on the 5th chromosome; the code is just different. in McClintock’s case, NOTHING was staying consistently ANYWHERE between multiple samples of corn). 
so McClintock was like, “hey uhhhhh these genes can jump wherever and the genome isn’t actually a stable consistent thing that we’re born with like we’ve thought it was up until now. like it turns out an organism’s genes can change over the course of its life responding to different environmental pressures, and part of how DNA accomplishes this is through making these weird jumping genes change positions when the organism is exposed to certain things.” 
this was a BIG mistake. she continued to publish her results for the next 15 years until she got so much hate she had to stop publishing the evidence she found not only for the existence of transposons, but her theories as to why they were there and what purpose they serve. other scientists in her (primarily male) field of experimental genetics REFUSED to believe this from her until nearly two decades later, when two male scientists- fellow biology students may recognize the names Francois Jacob and Jacques Monod, who worked with confirming the regulation of the lac operon and are still considered the fathers of epigenetics despite you know, not actually being the fathers of epigenetics since she did it twenty years earlier and i personally refuse to worship their shitty ass milk triumph- confirmed that genes could be, you know, regulated, and that the genome could be changed over the course of your life and that transposons were VERY MUCH possible and were also rediscovered in the following decade in similar encounters. anyway she casually won the nobel prize for her work in 1983, literally 40 years after she discovered it when everyone realized that she had been right all along and that they’d been belittling her and shitting on her for decades over it lol. 
anyway, all that aside: why is corn weird? why did it take until literally 2009 for us to map the maize genome for the first time? 
well here’s the kicker: 
the maize genome is 70-85% transposons or transposon-like elements depending on which variety you choose. 
70-85% of the genome of maize, in it’s natural form, literally does not stay in one place between generations. it just doesn’t. it fumbles around and breaks shit CONSTANTLY when exposed to different things. its an actual trainwreck in a constant state of slamming shit into other shit until shit happens. like given, plants in general have weird genomes and like, i can understand that and accept that, but this is actually fucking ridiculous. to put this in perspective, roughly 44% of the human genome is transposons or transposon-like elements. take that amount and double it and you have about the same amount of genomic chaos as maize. i’ve said it before and i’ll say it again: 
the maize genome is a goddamn build-a-bear workshop and it scares me

Lessons from the Gods
These are personal lessons I have learned while interacting with individual gods that I thought could be helpful lessons to others as well
Zeus- One’s past mistakes should not influence their present chances, within reason.
Hera- It is alright to not be a perfect mother and you shouldn’t try hiding any postpartum. It is better to admit the fear, pain, and bad thoughts and get help than to let them fester.
Hephaestus- Beauty belongs to those who stand tall despite what others say... Focus on what you can do and not what you can’t. Please yourself not others
Apollon- There’s a “beast” in each of us that we must face daily and you won’t always win, but you should keep fighting anyways.
Artemis- “Roles” are just loose guidelines that one should not take seriously. Do you. Always do you
Persephone- Your story will change with each new mouth that speaks it. Don’t let it bother you. You know the truth and those who matter will know the truth. That is what is important
Hermes- You can be extremely childish and act dumb all you want and still be extremely smart, cunning, and mature when the situation calls for it
Nyx- Elegance and grace does not come naturally to everyone and if it doesn’t for you but you still wish to cultivate it do not give it up. 
Hestia- Spoiling others for no real reason makes you feel so much happier.
Aphrodite- Whatever makes you feel beautiful is alright. If you feel beautiful covered in makeup wonderful. If you feel beautiful all natural, wonderful. If you feel beautiful with mud on your face.. Guess what? That’s wonderful. Real beauty shines through when you feel happy in your skins, no matter what covers it.
Hades- Doom and gloom is fun. Doom and gloom does not spell evil. Take pride in your personal doom and gloom. ((I like watching creepy stuff in the middle of the night and can’t fall asleep without a good ghost video playing and that’s awesome))
Athena- there is always more to learn and asking questions, no matter how “silly” or “stupid” they feel, is not something to apologize for. 
Thanatos- Being death positive is a good thing. We shouldn’t fear the most natural of things. Yes it is hard to imagine being gone from this world, but it is better to embrace it now and have things planned then to leave your loved ones with nothing to go on. Own your mortality and make it amazing while you can
Morpheus- Dreams don’t have to end when you open your eyes, you just have to keep working for them.

Im pretty sure those dandelion mutation pics are fake:/
actually, that’s an effect called fasciation, and it’s relatively common in the world of plant mutations! it’s characterized by the accidental fusing together of tissues on the stem/organ in question, which can lead to the weird funky/siamese twin flowers you see in the post. more specifically, it happens when the hormones in a plant’s growing tip (the apical meristem, for those plant physiology nerds out there) get messed up for whatever reason and the plant gets confused on what to separate, which results in a ‘crested’ flattened/fused organ. for example in certain plant illnesses it’s directly caused by a bacterial infection; the hormones secreted by the bacteria living in the growing tip mess up the plant’s chemical signaling and cause the fusing effect. it can also happen through all sorts of stuff, including viral, chemical, fungal, and genetic causes. 
i’ve seen three plants in my life like that: two were dandelions living by the side of a parking lot at my high school, and one was a branch of a bush that my plant pathology professor brought in to show us. it was on a plant in his backyard, and it had become infected with a bacterial infection that’s known for causing it. he was pretty excited lmao 
fasciation happens like...in a SHITLOAD of plants, as long as they’re vascular (meaning not mosses, basically), which makes sense, because the mutation needs a solid stem structure to happen. here’s a fasciated palm!
Tumblr media
and a fasciated rose! (no flowers on this one, although i think its really interesting that the plant still managed to make some thorns, if a bit tumultuously):
Tumblr media
and of course, gotta have a saguaro cactus! apparently this one lives happily in a botanical park in phoenix, arizona. good for her, out living her best life. shown here next to a normal cactus of the same species. 
Tumblr media
EXTRA fun fact, you may have seen THIS bad boy at ur local greenhouse, called Celosia argentea var. cristata, or ‘cockscomb celosia’ for short:
Tumblr media
well guess what it is??? a fasciated version of Celosia argentea grown commercially specifically for its rad ass appearance!! the normal, unmutated plant looks like this:
Tumblr media
seeing the two side by side makes it really easy to see how the plant could have messed them up just by failing to separate the flower stems right.
side note: these are not to be confused with the other variety of this plant, Celosia argentea var. plumosa, which is also popular in north american greenhouses for their funky little floofs (this pic shows a few different available colors, some of which the fasciated version are also grown in): 
Tumblr media
so in short.... those pics are real. plants just be fucked up like that.

What I’ve learned in 2017: 1. Vibes don’t lie. Trust the energy you’ve been receiving from the people you’re surrounded with. 2. I am an eternal and infinite source. As long as I’m alive there’s always love to give and things to learn. 3. There’s power in speaking words. If you want something say it out loud. Tell yourself and tell the universe. 4. Love exists but only if you speak highly of it in full belief. Love exists because I exist. 5. Sharing a couple of laughs with people doesn’t turn them into friends. Friends just happen. 6. Staying in the same places keeps you limited. There are pieces of you lying in different corners of the world. Home is home but sometimes you need to get out.

SOUL TIES
Tumblr media
Souls always connect, at the perfect time and place to fulfil an emotional, physical, mental or spiritual task or karmic bond. We are never connected to anyone by chance, there is always a higher lesson and a deeper message from the Universe. You atttact what your energy vibrates.
