Developmental dynamic transcriptomics reveals multiple effectors and transcription factors critical for Ditylenchus destructor parasitism.

ABSTRACT:

Background

Plant-parasitic nematodes (PPNs) pose a major threat to global agricultural production, yet fundamental research on their biology remains limited. The origin and evolutionary trajectory of PPNs remain elusive, largely due to the scarcity of chromosome-level genomic data. Among them, migratory PPNs are considered a key transitional form between free-living and obligate parasitic lifestyles, as they exhibit both plant parasitism and fungal feeding behaviors.

Results

In this study, we assembled a chromosome-level genome of the sweet potato rot nematode Ditylenchus destructor and confirmed the presence of four chromosomes through Hi-C scaffolding and karyotype analysis. Comparative genomic analysis with two others migratory PPNs, Bursaphelenchus xylophilus and Aphelen
