DRP1A is responsible for vascular continuity synergistically working with VAN3 in Arabidopsis.
Article in Plant physiology, 2005. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
In most dicotyledonous plants, vascular tissues in the leaf have a reticulate venation pattern. We have isolated and characterized an Arabidopsis (Arabidopsis thaliana) mutant defective in the vascular network defective mutant, van3. van3 mutants show a discontinuous vascular pattern, and VAN3 is known to encode an ADP-ribosylation-factor-GTPase-activating protein that regulates membrane trafficking in the trans-Golgi network. To elucidate the molecular nature controlling the vein patterning process through membrane trafficking, we searched VAN3-interacting proteins using a yeast (Saccharomyces cerevisiae) two hybrid system. As a result, we isolated the plant Dynamin-Related Protein 1A (DRP1A) as a VAN3 interacting protein. The spatial and temporal expression patterns of DRP1AGUS and VAN3GUS were very similar. The subcellular localization of VAN3 completely overlapped to that of DRP1A. drp1a showed a disconnected vascular network, and the drp1a mutation enhanced the phenotype of vascular discontinuity of the van3 mutant in the drp1a van3 double mutant. Furthermore, the drp1 mutation enhanced the discontinuous vascular pattern of the gnom mutant, which had the same effect as that of the van3 mutation. These results indicate that DRP1 modulates the VAN3 function in vesicle budding from the trans-Golgi network, which regulates vascular formation in Arabidopsis.
