老黄, did you see yesterday's news? Chinese scientists finally uncovered the secret of 'plant cell totipotency'.

I saw it! Truly stunning. Before, it was just a concept—that a single leaf could grow into a new seedling—but no one knew the precise mechanism.

Right. This time the team used single-cell sequencing and live imaging to fully document how one cell divides and becomes a new plant.

I recall they mentioned a 'switch': when a large amount of auxin accumulates in a cell, under specific environmental cues it can turn into a totipotent stem cell.

Exactly. And this discovery isn’t just cool—it can drastically shorten breeding cycles. For crops like wheat and soybeans, new varieties might be developed in just a few years.

This is hugely significant for agriculture—especially for conserving rare crops. Breeding used to be slow and resources could be lost, but now we can clone and preserve them quickly.

I think this will also affect food security. To solve China's '吃饭问题', we need original breakthroughs like this.

Plus, the results were published in *Cell*, showing strong recognition by international peers. After decades of effort, we finally have an answer.

Honestly, this is more exciting than any hype-tech. What truly changes the future are breakthroughs in basic science like this.

Yes. As the old saying goes: 'It takes ten years to grow a tree and a hundred years to cultivate a person.' Science is similar—it demands patience, but once a breakthrough arrives, its impact can last a century.
