Uncovering the key miRNA-target network of tea plants in resistance to sooty mold disease.

ABSTRACT:

Background

Sooty mold (SM) disease severely threatens tea plant health, reducing yield and quality. Driven by climate change and intensive farming practices, SM prevalence in China has surged, causing significant economic losses and forcing farmers to rely on chemical fungicides, which compromise environmental sustainability. Despite its impact, the molecular mechanisms underlying tea plant defenses against SM remain unclear.

Results

Integrated transcriptomic, sRNAome, and degradome analyses revealed that differentially expressed genes (DEGs) exhibited infection-level-dependent expression patterns. Post-transcriptional regulation by miRNAs was identified through sRNAome-degradome mapping, with six miRNA-target defense pairs validated by 5' RLM-RACE and qRT-PCR. Co-expression
