Molecular characterization of an ethylene receptor gene (CcETR1) in coffee trees, its relationship with fruit development and caffeine content.
Article in Molecular genetics and genomics : MGG, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
To understand the importance of ethylene receptor genes in the quality of coffee berries three full-length cDNAs corresponding to a putative ethylene receptor gene (ETR1) were isolated from Coffea canephora cDNA libraries. They differed by their 3'UTR and contained a main ORF and a 5'UTR short ORF putatively encoding a small polypeptide. The CcETR1 gene, present as a single copy in the C. canephora genome, contained five introns in the coding region and one in its 5'UTR. Alternative splicing can occur in C. canephora and C. pseudozanguebariae, leading to a truncated polypeptide. C. pseudozanguebariae ETR1 transcripts showed various forms of splicing alterations. This gene was equally expressed at all stages of fruit development. A segregation study on an inter-specific progeny showed that ETR1 is related to the fructification time, the caffeine content of the green beans, and seed weight. Arabidopsis transformed etiolated seedlings, which over-expressed CcETR1, displayed highly reduced gravitropism, but the triple response was observed in an ethylene enriched environment. These plants behaved like a low-concentration ethylene-insensitive mutant thus confirming the receptor function of the encoded protein. This gene showed no induction during the climacteric crisis but some linkage with traits related to quality.
