Inhibition of Developmental Processes by Flavone in Caenorhabditis elegans and Its Application to the Pinewood Nematode, Bursaphelenchus xylophilus

Abstract

Flavone (2-phenyl chromone) is a well-known plant flavonoid, but its bioactivity has been little explored. Treatment of Caenorhabditis elegans or C. brissage with flavones induced embryonic and larval lethality that was pronounced in early larval stages. This anti-nematodal effect was also observed in the pinewood nematode, B. xylophilus. LD50 values were approximately 100 mM for both B. xylophilus and C. elegans. Our results indicate that flavone is an active nematicidal compound that should be further investigated with the aim of developing a potent drug against B. xylophilus.

Keywords Anti-Nematodal activity, bursaphelenchus xylophilus, caenorhabditis elegans, caenorhabditis briggsae, embryonic lethality, flavone (2-phenyl chromone), larval lethality

COVER PICTURE
Kim et al. (pp. 710-724) demonstrated that a pathogen-derived Ralstonia pseudosolanacearum type III effector RipL delays flowering time and enhances susceptibility to bacterial infection in Arabidopsis thaliana. Shown is the RipL-expressing Arabidopsis plant, which displays general dampening of the transcriptional program during pathogen infection, grown in long-day conditions.
