# Issue Information

## TL;DR

A genetic duplication in the MdNAC18.1 promoter helps regulate fruit ripening by controlling ethylene production.

## Contribution

Discovery of an autosuppression module in the MdNAC18.1 promoter that fine-tunes fruit ripening.

## Key findings

- A 61-bp duplication in the MdNAC18.1 promoter acts as an autosuppression module.
- This module regulates fruit ripening by modulating ethylene biosynthesis.
- The study reveals a novel mechanism for controlling the tempo of fruit ripening.

## Abstract

Front cover image:

A 61‐bp duplication in the promoter provided MdNAC18.1 with an autosuppression module that regulates the overall tempo of fruit ripening through fine‐tuning ethylene biosynthesis. Cover illustration refers to the article published in this issue (Zhang et al., pp. 1216–1229).
