Phytochrome types in Picea and Pinus. Expression patterns of PHYA-Related types.
Article in Plant molecular biology, 1999. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
Knowledge of the genes in gymnosperms encoding the apoproteins of the plant photoreceptor phytochrome is currently scanty as for gymnosperm nuclear protein coding sequences in general. Here we report two complete cDNA-derived sequences which code for two different types of gymnosperm phytochrome. One sequence stems from Norway spruce (Picea abies) and the other from Scots pine (Pinus sylvestris). More detailed studies have shown that both types of phytochrome gene are present in Norway spruce. From phylogenetic analyses, these types appear to branch off from progenitors that are also the common ancestors of the angiosperm PHYA/PHYC and PHYB/PHYD/PHYE lineages. Partial phytochrome sequences of other gymnosperms cluster with either the one type or the other of the gymnosperm phytochrome genes characterized here. Southern blot analysis of Picea DNA using probes derived from the full-length Picea gene indicated a family of at least five members. Whether they code for new types may be doubted since only two phylogenetic clusters were found. Studies using RNA-PCR of Picea RNA extracted from either light- or dark-grown seedlings indicated that the steady-state levels of the transcripts of two PHYA/C-related genes were hardly affected by light.
