## TL;DR

A DEAD-box RNA helicase is crucial for rice embryo sac development and fertility.

## Contribution

Identifies OsRH52A as essential for functional megaspore specification and embryo sac development in rice.

## Key findings

- OsRH52A is required for proper embryo sac development in rice.
- Loss of OsRH52A leads to defective functional megaspore specification.
- OsRH52A plays a key role in seed setting and female fertility.
