Domestication‐associated reduction of methyl salicylate in tomato root and its significance for resistance to root‐knot nematode

New Phytologist, Volume 252, Issue 1, Page 414-426, October 2026.
Root volatile profiling reveals domestication‐associated variation in methyl salicylate (MeSA) accumulation in tomato. Summary Methyl salicylate (MeSA) plays diverse roles in the aerial parts of plants. By contrast, its biosynthesis and function in roots remain poorly understood.
