Unravelling the physiological and anatomical basis of divergent adaptations in cultivated and wild tomatoes.

ABSTRACT: Distinct physiological and anatomical traits can lead to substantial variation in photosynthetic efficiency among plant varieties, which may, in turn, impact agronomically important traits. We conducted a comprehensive comparative analysis of leaf physiology, anatomy, and biochemistry in Solanum lycopersicum (LEA), a modern inbred variety suited for the processing industry, and Solanum pennellii (Lost, accession LA5240), a drought-tolerant, green-fruited wild species, to investigate differences in photosynthetic performance and stomatal physiology. Lost exhibited higher photosynthetic capacity due to both biochemical and anatomical features. Chlorophyll fluorescence revealed that photosynthesis operates at a higher rate in Lost, due to greater electron sink capacity and efficient electron
