Abstract

Combined Transcriptome- and Proteome-based Analyses for Mining of Genes Associated with Fruit Cracking in Chinese Jujube (Ziziphus jujuba Mill.)

Highlights

Chinese jujube (Ziziphus jujuba Mill.) is an economically important fruit tree that originated in China and has been introduced to 48 countries across 5 continents (Liu et al, 2020).fruit dehiscence is the most important and common physiological disorder of Chinese jujube, it results in more than 50% of yield losses in severe cases (Chen et al, 2012)
Fruit cracking was associated with genes that regulate cell wall metabolism, unsaturated fatty acid oxidation and fruit skin hormone balance, including expansion (EXP) genes, pectinesterase (PE), and polyphenol oxidase (PPO) (Chen et al, 2015; Wang et al, 2019 Correia et al, 2020) This study aimed to identify genes and examine molecular mechanisms that are related to fruit dehiscence of jujube to serve as guidance for breeding strategies of fruit cracking-resistant cultivar and effective prevention and control of fruit dehiscence in jujube
About 89 genes were annotated to the Gene ontology (GO) database and 27 differentially expressed genes (DEGs) were annotated to 19 metabolic pathways

Summary

INTRODUCTION

Chinese jujube (Ziziphus jujuba Mill.) is an economically important fruit tree that originated in China and has been introduced to 48 countries across 5 continents (Liu et al, 2020). Fruit dehiscence is the most important and common physiological disorder of Chinese jujube, it results in more than 50% of yield losses in severe cases (Chen et al, 2012). Previous studies on fruit dehiscence mainly focused on morphological, anatomical and physiological characteristics. Transcriptome analysis has been used to analyse fruit dehiscence. Fruit cracking was associated with genes that regulate cell wall metabolism, unsaturated fatty acid oxidation and fruit skin hormone balance, including expansion (EXP) genes, pectinesterase (PE), and polyphenol oxidase (PPO) (Chen et al, 2015; Wang et al, 2019 Correia et al, 2020) This study aimed to identify genes and examine molecular mechanisms that are related to fruit dehiscence of jujube to serve as guidance for breeding strategies of fruit cracking-resistant cultivar and effective prevention and control of fruit dehiscence in jujube
