Spatiotemporal localization of jasmonate in the regulation of fruit set in tomato.

ABSTRACT: Tomato (Solanum lycopersicum) is a globally important crop, typically requiring pollination for fruit set. Seedless fruit production-fruit set without pollination (parthenocarpy)-is a desirable trait for horticulture, but its molecular mechanisms are not fully understood. Research on tomato fruit set has largely focused on phytohormones such as auxin and gibberellins (GAs), while the role of jasmonic acid (JA) remains unclear. Here, we identified a novel seedless mutant, Sldad1 (Solanum lycopersicum defective in anther dehiscence1) with a mutation in JA biosynthesis induced by ethyl methanesulfonate mutagenesis in the 'Micro-Tom' background. The wild type SlDAD1 was found to be specifically transcribed in the stamen filament, particularly 2 d before anthesis, with JA levels correlating to
