QTL mapping of wheat plant architectural characteristics and their genetic relationship with seven QTLs conferring resistance to sheath blight.
Article in PloS one, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
Sheath blight is one of the most devastating wheat diseases worldwide. Breeding resistant cultivars is the most powerful strategy to defeat the disease. Plant resistance on "disease escape" works through modulation of morphological traits and shows sustainable resistance to disease. Plant architectural traits have been reported to play a significant role in disease response. Therefore, exploring the genetic relationship between plant architecture and disease resistance is of importance to the understanding of plant resistance via "disease escape". Using an F9 population of 266 RILs (Recombinant Inbred Lines) derived from the cross of Luke × AQ24788-83, we have generated a linkage map of 631 markers on 21 chromosomes. In this study, we present the QTL identification of fourteen plant architectural characteristics and heading time from two years and analyze their genetic relationships with seven previously published QTLs to sheath blight (QSBs, QSe.cau), including plant height (PH), the space between the flag leaf and penultimate leaf (fdR), heading date (Hd), and other traits. Twelve stable QTLs of the morphological traits were identified with good consistency across five replicates. For the seven previously published QSBs, we found no significant association with plant height. However, some of the QSBs displayed strong associations with plant architectural traits and heading date. Especially, QfdR.cau-1AS, QHd.cau-2BS, QfdR.cau-5DL, and QfdR.cau-6BL were respectively mapped to the same regions as QSe.cau-1AS, QSe.cau-2BS, QSe.cau-5DL, and QSe.cau-6BL. Taken together, we have demonstrated that plant height did not exert a direct influence on the resistance to sheath blight conferred by the seven QSBs and that the plant architecture and heading date did exhibit a tight relationship with the resistance. Therefore, this study provides a novel evidence to help understand sheath blight resistance in wheat. In addition, the linked morphological characteristics and the generated flanking markers will facilitate breeding for resistance to sheath blight in wheat.
