Beschreibung:
24-Epibrassinolide (EBR) may act as a modulator for chilling injury in peach fruit during cold storage. The objective of this study was to investigate the potential role of EBR in regulating chilling resistance of peaches. Sucrose metabolism and energy metabolism were screened on the basis of GO annotation and KEGG pathway enrichment. Furthermore, EBR treatment promoted the activities and transcription levels of sucrose and energy metabolism-related enzymes. In addition, exogenous EBR maintained higher ATP content, energy charge, sucrose content, and hexose content, thus improved energy status and sucrose accumulation. These results provided a new insight that the enhancement of chilling resistance might be closely related to sucrose metabolism and energy metabolism in peach fruit by EBR treatment
