Transcriptome and metabolome analyses reveal the defense responses of Rhododendron hybridum 'Xiaotaohong' and 'Yangmeihong' petals to Neopestalotiopsis clavispora infection.

ABSTRACT:

Background

Flower blight is a fungal disease that significantly compromises the ornamental value of Rhododendron petals. However, the molecular mechanisms underlying the interaction between Rhododendron petals and pathogens remain poorly understood. To investigate the defense responses of Rhododendron hybridum petals to pathogenic infection, this study employed transcriptomic and widely targeted metabolomic approaches to analyze constitutive metabolites differences between the resistant cultivar Rhododendron hybridum 'Yangmeihong' (YMH) and the susceptible cultivar 'Xiaotaohong' (XTH), as well as changes in gene expression and metabolite accumulation following infection with Neopestalotiopsis clavispora.

Results

A total of 144 constitutive metabolites were identified in YMH
