Seedling resistance and chemical defenses against Psylliodes chrysocephala : the roles of seed age and sinapinic acid in Sinapis alba and Brassica napus

Key Points

The aim is to examine the variation in cotyledon-stage resistance to Psylliodes chrysocephala and the role of seed age and sinapinic acid.
Analyzed cotyledon-stage resistance among different Brassicaceae species.
Identified the role of sinapinic acid in seedling resistance.
Examined seed age effects on resistance traits.
Variation in resistance to Psylliodes chrysocephala was found among species.
Sinapinic acid plays a significant role in the resistance mechanisms.
S. alba shows potential as a source for breeding insect-resistant crops.

Abstract

We successfully identified variation in cotyledon-stage resistance to P. chrysocephala among Brassicaceae species. These findings highlight the potential of S. alba as a source of resistance traits and suggest that seed physiology influences seedling resistance, offering new avenues for breeding insect-resistant oilseed crops, which are needed for integrated pest management. © 2026 The Author(s).
