Ovule development: identification of stage-specific and tissue-specific cDNAs.
Article in The Plant cell, 1996. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 43 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
A differential screening approach was used to identify seven ovule-specific cDNAs representing genes that are expressed in a stage-specific manner during ovule development. The Phalaenopsis orchid takes 80 days to complete the sequence of ovule developmental events, making it a good system to isolate stage-specific ovule genes. We constructed cDNA libraries from orchid ovule tissue during archesporial cell differentiation, megasporocyte formation, and the transition to meiosis, as well as during the final mitotic divisions of female gametophyte development. RNA gel blot hybridization analysis revealed that four clones were stage specific and expressed solely in ovule tissue, whereas one clone was specific to pollen tubes. Two other clones were not ovule specific. Sequence analysis and in situ hybridization revealed the identities and domain of expression of several of the cDNAs. O39 encodes a putative homeobox transcription factor that is expressed early in the differentiation of the ovule primordium; O40 encodes a cytochrome P450 monooxygenase (CYP78A2) that is pollen tube specific. O108 encodes a protein of unknown function that is expressed exclusively in the outer layer of the outer integument and in the female gametophyte of mature ovules. O126 encodes a glycine-rich protein that is expressed in mature ovules, and O141 encodes a cysteine proteinase that is expressed in the outer integument of ovules during seed formation. Sequences homologous to these ovule clones can now be isolated from other organisms, and this should facilitate their functional characterization.
