Developmental regulation and downstream effects of the knox class homeobox genes Oskn2 and Oskn3 from rice.
Article in Plant molecular biology, 2002. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Plant homeobox genes of the class 1 knox (knotted1-like) type are involved in the regulation of shoot apical meristem formation and function. Their expression generally occurs either throughout the meristem or specifically at the lateral organ boundaries. Down-regulation in the organ primordia is tightly controlled and misexpression in leaves leads to a perturbed development. Here, the transcriptional control of two rice knox genes, Oskn2 and Oskn3, was addressed, showing that the promoter sequences of both genes mediate the initial down-regulation during lateral organ formation, but are insufficient to keep expression in lateral organs stably off. Therefore, maintenance of the repressed state requires control elements outside the promoter regions. Ectopic expression of Oskn2 or Oskn3 induced similar defects in panicle branching. internode elongation and leaf patterning. However, small differences suggested that their target gene specificities are not completely overlapping. This was supported by the observation that Oskn3 protein but not Oskn2 could interact with two reported recognition sequences of a KNOX protein from barley. Finally, protein-protein interactions may contribute to the functioning of KNOX proteins, as the ability of Oskn3 and Oskn2 to form heterodimers could be demonstrated.
