Possible involvement of genes on the Q chromosome of Nicotiana tabacum in expression of hybrid lethality and programmed cell death during interspecific hybridization to Nicotiana debneyi.
Article in Planta, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 17 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
Hybrid seedlings from the cross between Nicotiana tabacum, an allotetraploid composed of S and T subgenomes, and N. debneyi die at the cotyledonary stage. This lethality involves programmed cell death (PCD). We carried out reciprocal crosses between the two progenitors of N. tabacum, N. sylvestris and N. tomentosiformis, and N. debneyi to reveal whether only the S subgenome in N. tabacum is related to hybrid lethality. Hybrid seedlings from reciprocal crosses between N. sylvestris and N. debneyi showed lethal characteristics identical to those from the cross between N. tabacum and N. debneyi. Conversely, hybrid seedlings from reciprocal crosses between N. tomentosiformis and N. debneyi were viable. Furthermore, hallmarks of PCD were observed in hybrid seedlings from the cross N. debneyi x N. sylvestris, but not in hybrid seedlings from the cross N. debneyi x N. tomentosiformis. We also carried out crosses between monosomic lines of N. tabacum lacking the Q chromosome and N. debneyi. Using Q-chromosome-specific DNA markers, hybrid seedlings were divided into two groups, hybrids possessing the Q chromosome and hybrids lacking the Q chromosome. Hybrids possessing the Q chromosome died with characteristics of PCD. However, hybrids lacking the Q chromosome were viable and PCD did not occur. From these results, we concluded that the Q chromosome belonging to the S subgenome of N. tabacum encodes gene(s) leading to hybrid lethality in the cross N. tabacum x N. debneyi.
