## TL;DR

A new genetic mutation in maize prevents silk growth, offering a novel way to control pollination useful for baby corn breeding.

## Contribution

A single-gene mutation is identified that inhibits silk growth in maize, providing a novel genetic approach to pollination control.

## Key findings

- A single-gene mutation inhibits maize silk growth.
- This mutation offers a novel genetic approach to control pollination.
- It has potential application in baby corn breeding.

## Abstract

A single-gene mutation inhibits maize silk growth, delivering a novel genetic approach to pollination control with an attractive potential for application in baby corn breeding.
