Perturbation of periodic spot-generation balance leads to diversified pigmentation patterning of harlequin Phalaenopsis orchids: in silico prediction.
Article in BMC plant biology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 3 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
backgroundA retrotransposon HORT1 in the promoter of the anthocyanin activator gene PeMYB11, microRNA858 (miR858) that targets PeMYB11, and a repressor PeMYBx have been implicated in pigmentation patterning diversity of harlequin Phalaenopsis orchids. However, the interrelationship among them remains to be elucidated.
resultsTo understand how these factors interact to generate anthocyanin spots in Phalaenopsis, we successfully developed a mathematical model based on the known reaction-diffusion system to simulate their interplay and refined the conceptual biological model. Intriguingly, the expression of both PeMYBx and PeMYB11 were in phase for purple spot formation, even though they showed adverse effects on anthocyanin accumulations. An increase in the self-activation rate of PeMYB11 resulted in the increased size of purple spots, but no effects on spot fusion. Decreased degradation rate of miR858 in the purple regions, led to disruption of the formation of spotted pigmentation patterning and a full-red pigmentation pattern. Significantly, the reduced miR858 level promotes the fusion of large dark purple dots induced by the solo-LTR of HORT1, eventually generating the purple patches. In addition, the spatially heterogeneous insertion of HORT1 caused by the remnant solo-LTR of HORT1 derived from random homologous unequal recombination of HORT1 in individual cells of floral organs could explain the diverse pigmentation patterning of harlequin Phalaenopsis.
conclusionsThis devised model explains how HORT1 and miR858 regulate the formation of the pigmentation patterning and holds great promise for developing efficient and innovative approaches to breeding harlequin Phalaenopsis orchids.
