APETALA2/ethylene responsive factor in fruit ripening: Roles, interactions and expression regulation

Area of Science:

• Plant Biology
• Molecular Biology
• Agricultural Science

Background:

• Fruit ripening involves complex physiological and biochemical changes essential for human nutrition and seed dispersal.
• The APETALA2/ethylene responsive factor (AP2/ERF) family of transcription factors plays a crucial role in regulating these ripening processes.
• Understanding AP2/ERF functions is vital for improving fruit quality and yield.

Purpose of the Study:

• To review the regulatory mechanisms of AP2/ERFs in fruit ripening.
• To highlight recent findings on AP2/ERF target genes and co-regulators.
• To provide a comprehensive perspective on AP2/ERF roles in fruit development and quality.

Main Methods:

• Literature review focusing on AP2/ERF transcription factors in fruit ripening.
• Analysis of published data on AP2/ERF target genes, co-regulators, and protein interactions.
• Synthesis of information on hormonal signaling and epigenetic modifications influencing AP2/ERF activity.

Main Results:

• AP2/ERFs are critical regulators of key fruit-ripening attributes like pigmentation, texture, and flavor.
• Their regulatory mechanisms involve interactions with other proteins and orchestration of phytohormone signaling networks.
• Epigenetic modifications play a role in modulating AP2/ERF gene expression during ripening.

Conclusions:

• AP2/ERFs are central players in the complex network controlling fruit ripening.
• Further research into AP2/ERF interactions and regulatory pathways can lead to enhanced fruit quality.
• This review serves as a reference for future studies on AP2/ERF functions in fruit development.
