Transcriptome analysis reveals key pathways and regulatory networks involved in soybean's early resistance to Peronospora manshurica.

ABSTRACT:

Background

Soybean downy mildew (SDM), caused by the obligate parasite Peronospora manshurica (Pm), is a global fungal disease that significantly reduces soybean yield and quality by inducing early leaf drop and decreasing both 100-seed weight and seed oil content. Therefore, investigating the molecular mechanisms underlying early resistance to Pm infection in soybean, along with its key regulatory networks, is of paramount importance for developing effective strategies to combat Pm invasion.

Results

This study employed transcriptome sequencing at six time points before and after Pm inoculation in a highly resistant (HR) soybean accession, Jiaohe xiaoheidou (JH), and a highly susceptible (HS) accession, Jilin 5 (JL). Differentially expressed genes (DEGs) in both accessions w
