Our story

We started with a question no one had answered.

What if you could engineer the chloroplast?

Plastomics was founded on the premise that crop biotechnology had been looking in the wrong place. For four decades, agricultural biotech focused almost exclusively on the plant nucleus — the most obvious site to insert a new gene. But some of the most important genes in agriculture aren't in the nucleus. They're in the chloroplast.

The chloroplast genome encodes the machinery of photosynthesis — the single most important biological process in agriculture. Improving it could unlock step-change gains in crop yield, protein production, and resilience. But doing so requires the ability to access, transform, and edit chloroplast genes. That's what Plastomics was built to do.

Mission

To unlock the full potential of the chloroplast — engineering crops that are more productive, more resilient, and more capable than what's possible through nuclear biotech alone.

Where we are

Based in St. Louis, Missouri — the world's center of agricultural innovation. We bring together plant molecular biologists, crop scientists, and regulatory experts united by a single mission. St. Louis has long been home to the science that feeds the world; Plastomics is proud to carry that tradition into the next frontier of crop engineering.
