Unravelling the physiological and anatomical basis of divergent adaptations in cultivated and wild tomatoes.
Article in Journal of experimental botany, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

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 flow through the photosystems. Lost also showed higher Rubisco content as well as greater chlorophyll a/b ratio and total soluble protein levels than LEA, demonstrating investments in carbon capture relative to light harvesting to support superior photosynthetic performance at higher light intensities. Equal stomatal numbers on the abaxial and adaxial surface for Lost supported its greater leaf thickness and higher photosynthetic capacity, whilst LEA's greater stomatal density on the abaxial surface is typical of commercial broadleaf crops. Grafting experiments demonstrated that LEA scions grafted onto Lost rootstocks displayed improved photosynthesis compared with non-grafted LEA and LEA self-grafted plants, demonstrating successfully transferred enhanced photosynthetic traits from rootstock of Lost to LEA scions. Our study highlights the photosynthetic advantages of Lost and suggests avenues for enhancing tomato productivity through trait transfer.
