Most people meet plant cell culture in the grocery store without knowing it. You see it in the perfect row of blueberries, the identical bananas, the white orchids that look the same every single year. You do not see the lab bench and the flask behind them.
On The Innovators, I talked with Yoni Kalin, CEO of Plant Cell Technology, about the quiet infrastructure under all of that. His company has been working in plant tissue culture since 1993. What started as a small family business selling “pet plants” in jars has grown into a Utah based factory, a catalog of more than 500 products, and a bridge between plants, animal cells, fungi, and the people who work with them.
At the core, Plant Cell Technology makes the media and tools that keep cells alive and dividing. In the plant world that means the gel or liquid that feeds tiny cuttings, the nutrients that turn one node into a full clone. In the animal world that means the formulas that keep mammalian cells healthy in dishes and flasks. You can think of them as the food and basic kit that every lab needs before any vaccine or seedling can exist.
For the first thirty years they stayed in the plant lane. Last year they bought a manufacturing facility and stepped into mammalian cell culture. Now they blend media for human, animal, and insect cells as well. That move puts them inside the engine room of pharma and biotech, where the same cell lines are used for decades to test drugs and make biologic medicines.
Yoni gave a simple example. CHO cells, Chinese hamster ovary cells, have been in use since the middle of the last century. The original cells came from one animal. That line has been split and expanded for more than eighty years. Those cells are a standard test bed. If you want to grow a protein drug or check how something behaves, you feed those cells and watch. That kind of work used to mean a lot of live animal testing. The more you can do in culture, the less you have to do in a whole animal.
Plant cell culture is less visible but just as important. Instead of planting a seed and accepting whatever mix of traits comes back, growers take a cutting from a known plant, usually a meristem or small node, and regrow it in sterile media. The result is an exact clone of the parent. Every plant you make that way has the same genetics and the same performance.
If you are a berry grower, that consistency matters. It is the reason the box of blueberries you pick up in January tastes like the one you bought in July. If you are a greenhouse operator selling fancy houseplants, it means you can produce a thousand copies of the one pink variegated plant everyone wants instead of hoping more seeds turn out the same way. In orchards, forests, and replanting projects, it means you can fill a hillside with trees that all have the traits you need for that climate.
It is also the reason you can walk into a store like Trader Joe’s or Home Depot and see the same orchid color and shape every year. Orchid seeds are rough to work with. Cloning them in tissue culture lets growers keep exact copies of the best lines in circulation.
Plant Cell Technology sits in that supply chain as a “picks and shovels” vendor, to borrow Yoni’s phrase. They do not sell the fruit or the orchids. They sell the media, the bioreactors, the lab gear, and the training that lets growers and researchers do the work.
That education piece is important and it is where things get interesting outside the pure lab. Until a few years ago, if you wanted to learn plant tissue culture, you went to a university or a big corporate lab. You paid tuition or you got hired. Everyone else was on the outside.
Around 2020, while people were learning to bake sourdough and dance on short videos, Plant Cell Technology started posting long form instructional content. They now have hundreds of free videos that cover the basics, from aseptic technique to plant physiology to step by step protocols for setting up a small lab. On top of that they run in person and online master classes that focus on practical scale, not just textbook purity. Their goal is to teach you how to produce ten million banana plants, not just how to pass a midterm.
That effort has pulled in a new crowd, hobbyists and small entrepreneurs who want to clone rare plants at home. Anyone who has wandered into a trendy plant shop and seen a single cutting selling for forty or fifty dollars knows the appeal. With basic gear, a clean space, and the right media, you can take a small piece of that plant and grow hundreds of copies. That can feed a side business or just fill your home with green.
The same idea applies to fungi. Mycology is booming, and tissue culture is a good way to preserve and expand mycelium strains. It is easier in some ways, since many fungal media formulas are simple, often just agar and sugar. Yoni sees that as a gateway for people who might later move into more complex plant or mammalian work.
Behind the scenes, the company is pushing on automation. Tissue culture has been labor heavy for decades. A tech sits at a clean bench, cuts, transfers, seals jars, and repeats. That is slow and expensive.
Plant Cell Technology’s answer is a low cost bioreactor they call the BioCoupler, paired with an automated system called BioTilt. Instead of growing plantlets on gel in jars, they suspend plant cells or tiny explants in liquid and cycle them through soaking and draining. Soak, let them breathe, soak again. That simple rhythm gives the plant material full contact with nutrients, then air, which speeds up growth. Yoni says they see multiplication rates many times higher than on static gel media.
The cost drops too. Gel agents like agar and gellan gum are not cheap. A single kilogram can run close to a couple hundred dollars. A liquid system needs less of that. The BioTilt handles timing and immersion automatically. Sensors and software can watch the process, adjust schedules, and log data in a way a human tech with a clipboard cannot match.
The vision is clear. Larger labs and commercial houses will bring in robotics that can cut and move plant material. Bioreactors will handle the growth phase. AI systems will watch sensors, track contamination, and refine conditions. That kind of setup already exists at the very high end. Yoni wants to drag it into the middle of the market and make it less exotic.
When I asked him if this was the future of agriculture, he pushed back a bit. This is the present, he said. Seeds are not going away. Fields and barns are not going away. What he sees coming is a stack. At the bottom, a tissue culture lab where farmers keep their own genetics and do their own breeding. Above that, nursery space. Above that, growing and harvest.
Vertical farming has been a buzzword for a while. Tissue culture gives it teeth. You can stack genetics in a small lab that would need vast acreage outside. You can build local food systems that rely less on long chains of seed companies and middlemen. You can give farmers some control over the varieties they plant, instead of locking them into sterile seed contracts that keep them dependent.
Plant Cell Technology has moved a long way from a single “pet plant” in a jar. Under Yoni’s leadership, the company has turned into a small ecosystem, part manufacturer, part educator, part guide into a field that is usually hidden behind white coats and controlled access doors.
If you are a researcher who needs media, a grower who wants to scale, or a curious person who just wants to clone a favorite houseplant instead of buying three more, their site at plantcelltechnology.com is a place to start. The tools that shape our food and forests are no longer reserved for the biggest labs. They are slowly moving into reach, one flask at a time.
