The IQ67-domain protein IQD1 regulates fruit shape through complex multiprotein interactions in pepper (Capsicum annuum L.).

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
Natural genetic variation can be used to improve important crop agronomic traits, and understanding the genetic basis of natural variation in fruit shape can help breeders develop pepper varieties that meet market demand. In this study, we identified a QTL controlling fruit length-width ratio by conventional genetic mapping, encoding a previously uncharacterized gene CaIQD1. Reduced CaIQD1 expression resulted in short and wide fruits in pepper, whereas heterologous overexpression of CaIQD1 resulted in narrower fruits in tomato. Further experiments suggested that CaIQD1 regulates fruit shape in pepper by affecting cell proliferation, expansion and morphological changes. CaIQD1 also has a direct protein interaction with CaOFP20 in CaTRM-like-CaOFP20. Reduced CaOFP20 expression caused pepper fruits to become elongated and curved, whereas reduced CaTRM-like expression led to the formation of rounder fruits. These gene expression changes had a significant effect on the expression of genes related to the cell cycle and cell expansion. The CaTRM-like-CaOFP20-CaIQD1 module may thus represent a conserved regulatory pathway for controlling pepper fruit shape. CaIQD1 also showed direct interactions with the pepper calmodulin CaCaM7, the tubulin CaMAP70-2 and the microtubule motor protein CaKLCR1, suggesting that the regulation of fruit shape by CaIQD1 is related to changes in microtubule dynamics mediated by Ca
