Analysis of the browning mechanism of fresh-cut sweetpotato: based on physiological and biochemical dynamics and multi-omics integrated analysis

Q: What does this research mean for the field?

The browning of fresh-cut sweetpotato is driven by rapid membrane damage, reactive oxygen species bursts, and overactivated phenylpropanoid and hormone pathways regulated by transcription factors IbMYB308, IbMYB102, IbWRKY53, and IbWRKY29.

Key Points

The study aims to understand the browning mechanism in fresh-cut sweetpotato through physiological and biochemical analysis.
Analyzed membrane damage and reactive oxygen species (ROS) levels in Jishu 26 and Xinxiang varieties.
Utilized multi-omics to assess metabolic pathways involved in browning.
Investigated the regulation of key transcription factors IbMYB308, IbMYB102, IbWRKY53, and IbWRKY29.
Jishu 26 exhibited rapid membrane damage and significant ROS bursts compared to Xinxiang.
Multi-omics analysis indicated an overactivation of phenylpropanoid and hormone pathways during browning.
Transcription factors IbMYB308, IbMYB102, IbWRKY53, and IbWRKY29 were identified as regulators of the browning process.

Implication

Analysis demonstrates the browning process in fresh-cut sweetpotato, suggesting potential regulatory pathways.

Abstract

• Jishu 26 shows rapid membrane damage and ROS burst vs. Xinxiang. • Multi-omics reveals overactivated phenylpropanoid and hormone pathways. • IbMYB308, IbMYB102, IbWRKY53 and IbWRKY29 regulate browning.
