1 · What the graph read from it

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.

2 · The registry

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

Two previously uncharacterized Vitis vinifera CONSTANS-like genes (VvCO, VvCOL1), which are predicted to encode proteins with homology to members of the Arabidopis CONSTANS family, were identified. Under controlled conditions, both genes show a diurnal expression pattern with peak at dawn. During grapevine bud development, VvCOL1 is mainly expressed in dormancy, suggesting a participation in the transcriptional photoperiod control of bud dormancy induction and maintenance in this species. On the other hand, VvCO expression in latent buds is in agreement with a function during flowering induction. A spatial and temporal relationship in the expression of VvCO, VFY and VvMADS8 (the Arabidopsis LEAFY and SUPPRESSOR OF OVEREXPRESSION OF CONSTANS 1 orthologues) in latent buds is observed, suggesting that these genes are involved in the seasonal periodicity of flowering in grapevines. Furthermore, our results provide a new molecular insight into tendril development showing that grapevine CO homologues are also expressed in this distinctive organ.
