Integrative transcriptomic and metabolomic profiling reveals dynamic differences in pathogen resistance to twig blight in Myrica rubra.

ABSTRACT:

Background

Twig blight (TB), caused by Pestalotiopsis-like species, induces twig dieback in Myrica rubra, leading to substantial economic losses in its production across China and posing a significant threat to M. rubra cultivation. To date, the immune response of M. rubra to Pestalotiopsis-like infections remains poorly understood.

Results

In this study, full-length transcriptomics and untargeted metabolomics were employed to investigate the immune responses of resistant "Dingao" (DA) and susceptible "Dongkui" (DK) M. rubra cultivars to Pestalotiopsis pathogen infection at early (1DPI) and later (5DPI) stage. The main findings revealed that the resistant DA triggered a rapid and robust immune response at 1DPI, with 1,111 differentially expressed genes (DEGs), including 583
