Transcription-metabolism association analysis of molecular mechanisms in sweet orange plants in response to boron deficiency.

ABSTRACT: Sweet orange (Citrus sinensis) is the most widely grown citrus fruit worldwide, with the highest production and largest cultivated area. Serious problems associated with boron (B) deficiency are emerging in most old production areas, resulting in the lignification of sweet orange flesh and fruit souring. However, the molecular mechanisms through which sweet orange plants react to boron deficiency stress remain unreported in the literature. Through transcriptome analysis and RT-qPCR expression validation, this study revealed that CsBBX11, CsBBX13, and CsBBX14 may play important roles in the response of sweet orange plants to boron deficiency stress. Metabolomic analysis revealed that the contents of quercetin 3-glucoside, taxifolin, and isovitexin all exceeded 1 µg/g, with significant diffe
