Phylogenetic and evolutionary analysis of NBS-encoding genes in Rutaceae fruit crops.
Article in Molecular genetics and genomics : MGG, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The nucleotide-binding site leucine-rich repeat (NBS-LRR) genes are the largest class of disease resistance genes in plants. However, our understanding of the evolution of NBS-LRR genes in Rutaceae fruit crops is rather limited. We report an evolutionary study of 103 NBS-encoding genes isolated from Poncirus trifoliata (trifoliate orange), Citrus reticulata (tangerine) and their F(1) progeny. In all, 58 of the sequences contained a continuous open reading frame. Phylogenetic analysis classified the 58 NBS genes into nine clades, eight of which were genus specific. This was taken to imply that most of the ancestors of these NBS genes evolved after the genus split. The motif pattern of the 58 NBS-encoding genes was consistent with their phylogenetic profile. An extended phylogenetic analysis, incorporating citrus NBS genes from the public database, classified 95 citrus NBS genes into six clades, half of which were genus specific. RFLP analysis showed that citrus NBS-encoding genes have been evolving rapidly, and that they are unstable when passed through an intergeneric cross. Of 32 NBS-encoding genes tracked by gene-specific PCR, 24 showed segregation distortion among a set of 94 F(1) individuals. This study provides new insight into the evolution of Rutaceae NBS genes and their behaviour following an intergeneric cross.
