<i>AoMYB114</i> transcription factor regulates anthocyanin biosynthesis in the epidermis of tender asparagus stems.

ABSTRACT:

Introduction

Asparagus is a valuable vegetable, and its edible part is a tender stem. The color of the tender stem epidermis is an important trait. In particular, purple asparagus is rich in anthocyanins. However, the molecular mechanisms underlying anthocyanin accumulation in purple asparagus remains unclear.

Methods

The white variety 'Jinguan' (JG), the green variety 'Fengdao 2' (FD), and the purple variety 'Jingzilu 2' (JZ) were compared using physiological and transcriptomic analysis. High-performance liquid chromatography and real-time quantitative polymerase chain reaction were employed to detect anthocyanins and validate gene expression.

Results

Cyanidin 3-glucoside and cyanidin 3-rutinoside were detected as the main anthocyanins in JZ. Transcriptome data demon
