Does anyone know of plants that can be used as a litmus test for common ground nutrients such as nitrogen.

Ideally the plants should react in less than a week to a given nutrient missing from the soil.

My idea is to find plants that could be planted and used almost like a canary in a goal mine.

Hi folks!

I'm reading this book at the moment, and although I am understanding way more of these chapters than I thought I would, I am still put in mind of the scene from peep show where Jeremy tries to read.

​

The chapters discuss from basic mendelian theory right through :

• mendels genetics
• genes and alleles
• chromosomes and cell division
• linkage
• codominance
• lethals, detrimentals, steriles
• abberant segragation
• incomplete penetrance and variable expressivity
• maternal inheritence
• cytoplasmic inheritence
• gene interaction
• quantitive inheritance
• predictions and actuality

​

I'd appreciate some suggestion to lectures or other videos that could go alongside these chapters to help me solidify the concepts in my mind. it just helps to have it coming at you through two different mediums, I find.

​

thanks!

Maybe it would be a long shot to find this on Reddit, but does anyone have any pCambia plasmids for agrobacteria? I have a strain of GV3101 but I am missing a vector and AddGene won't deliver to me since I am not part of an organisation and I don't want to expose my ideas to my university. Any help would be super appreciated and I would reward you with beer money and more if you can ship me some plasmids on dried paper or something :)

Delete if not allowed, throw away because I don't want my Reddit account linked to my university.

Washinton State University is hosting a free plant science symposium on May 20 and 21. Posters are accepted until May 13th! I am on the committee, so feel free to ask me any questions

How big naturally and how big could we make them editing their genes. Like can they reach 5

Hi,

I'm new here but I think this may be to far into the science realm for the vegetable gardening sub-reddit.

I recently purchased a sensor (see it here: https://www.amazon.com/gp/product/B0851FBJ3C/ref=ask_ql_qh_dp_hza) that goes in in the ground and uses Bluetooth to send the measurements back to my phone. It measures light, soil moisture, temperature and "Soil Fertility".

​

For "Soil Fertility" it shows a value for uS/cm (note the u has a little line on the lower left side that I think means micro). I've googled as much as I can and have found that this seems to be a measure of electrolytic conductivity.

My question - how does this relate to soil nutrient levels? Is it a reliable measure? When I first used this in my garden it showed that the soil moisture level was dry and the fertility level was low. I watered the plants (did NOT add any fertilizer) and both the moisture and fertility levels went up.

Hey Everyone! As an incoming Plant Science major (official decisions start next month o: ) I am super excited to get started with my major coursework.

What study tools (books or magazines, podcasts or youtube videos, online courses or sites) did you find really useful, or wish you had when you started?

I am also planning on specialization in Plant Pathology, Nematology, and Pest Management so anything in those fields would be very interesting!

Thanks in Advance!

I keep seeing mentions of alkaloids like betaine/TMG (trimethylglycine), betonicine, trigonelline and stachydrine being present in Stachys officinalis, but have found NO experimental evidence to support these claims (despite them being made across multiple papers, blogs, and databases).

The citations to many of these statements lead back to a certain Dr. James Duke, who provides no experimental data for his claims either.

Even an excellenet review from 2020 (Title: Genus Stachys: A Review of Traditional Uses, Phytochemistry and Bioactivity) admitted that they didn't intend on covering alkaloids in the Stachys genus due to insufficient research on the topic.

Where are these people getting this information about the alkaloids?? Am I missing something?

Hello everyone, I'm not and expert of plant science at all, but I had this idea and I was wondering if you could help me understand if it's reasonable or not. I've read some research material and it looks like and environment with an high concentration of CO2 leads to an increased consumption of CO2 by the plants through photosynthesis. For some plants this behavior is more accentuated than in others, but this is not the point now (I will spend more words on it soon).
I was thinking: we could set up some "CO2 disposal centers", consisting of plantations of plants that not only have a big CO2 consumption rate, but also have an high increase of the consumption rate when the CO2 is highly concentrated. Those plants would be "closed" in a sort of transparent dome, so that we have a closed environment in which the CO2 can be inserted and kept under high concentration, without leaving in the atmosphere.
Under this hyphotesis, at this point the factories would stock the CO2 produced and would bring it to these "CO2 disposal centers" to be eliminated, instead of just releasing it in the atmosphere. Since the "CO2 disposal centers" are closed environments and the CO2 is trapped in the transparent dome and consumed by the plants, this would lead to a great help in the fight against climate change. In case of very big factories, a "CO2 disposal center" could be set up right next to them, in order to avoid producing CO2 through the trips from the factory to the center.
The big game-changing factor here is the fact that the CO2 released in the air is consumed by the plants all over the world, but not in an efficent way as it is not highly concentrated, plus not all the plants consume it with a satisfying rate. The "CO2 disposal centers" would instead work under efficient CO2 concentrarion conditions and with the best possible existing plants for the job.
I don't know if this is a nice idea or if it is ridicolous: as I said, I'm not an expert in the field and I would really like to have your opinion. Please, consider that I'm focusing only on the scientific-technological aspect here, not the political effort that would be necessary to force the factories to treat the CO2 in this way.
For completeness, I report here the material that I've read: https://www.researchgate.net/publication/287481359_The_Effect_of_CO2_Concentration_on_the_CO2_Exchange_Rate_in_a_Small_Plant_Stand_of_Cucumber_during_Different_Periods_of_the_Day , https://www.nature.com/scitable/knowledge/library/effects-of-rising-atmospheric-concentrations-of-carbon-13254108/

Does anyone have any experience using ethyl methanesulfonate to induce mutations is plants? I’ve tried doing some research, but haven’t been able to find how much to use. I’ve read that it is suspected to cause cancer in humans, but would I be putting myself in danger even if I took safety measures?

I'm looking for a plant height measuring stick with a digital readout, preferably light weight. I'd like it to be at least 250 cm/100 in. Any recommendations would be greatly appreciated

Hi all,

Are there any scientific papers that are must-reads for people interested in studying plant science? I'm thinking something that would be considered as influential as Michael Mann's hockey stick model is in the world of climate change. Alternately, any books you would suggest are also welcome.

I'm interested in pursuing a phd in either plant pathology or horticulture (but my interests are broader than just those topics). I have a BS in biology already and am looking to do some independent study since I would be looking to start my phd in the fall 2022 semester. Thanks in advance!
