Vestigial Plastids in Parasitic Plants: Evolutionary Remnants or Adaptive Innovations?
Review in Plant, cell & environment, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Throughout the evolutionary history of plants, chloroplasts originating from a cyanobacterial endosymbiosis have undergone remarkable adaptation and specialization, giving rise to a multitude of plastid types. The evolution toward parasitism in plants represents a particularly extreme case of such specialization. In holoparasitic species, the relaxation of selective pressures to maintain photosynthesis has led to the progressive loss of photosynthesis-related genes and the emergence of vestigial plastids. These organelles are often highly reduced in size, frequently devoid of thylakoids and can accumulate lipids, pigments, proteins and/or starch. The study of these reduced plastids in parasitic plants is conceptually challenging yet offers a unique opportunity to uncover fundamental principles of plastid biology during evolution. In this review, we discuss recent progress in understanding the biology of these vestigial plastids, exploring their unique morphology and functions, and how photosynthesis, photoprotection and retrograde signalling have evolved. Finally, we highlight the advantages of shifting such key physiological traits for adaptation into new ecological niches for the evolutionary success of holoparasitic plants.
