Fertilization induces strong accumulation of a histone deacetylase (HD2) and of other chromatin-remodeling proteins in restricted areas of the ovules.
Article in Plant molecular biology, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 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
Fertilization triggers a unique and complex developmental program leading to embryogenesis and seed set. Recently, mutations affecting chromatin-remodeling enzymes in plants have shown their key roles in development as demonstrated before in animal cells. Using a negative selection screen to isolate genes expressed in ovary tissues upon fertilization, we have identified a histone deacetylase gene (named ScHD2a ) of the plant-specific HD2 family, which is predominantly expressed in ovaries of the self-incompatible species Solanum chacoense. The ScHD2a is the probable orthologue of the Arabidopsis thaliana AtHD2a gene, which upon antisense suppression leads to aborted seeds formation. Transcription of the ScHD2a gene is strongly triggered by fertilization and transcripts accumulate predominantly in the micropylar region of the ovule's integument. Interestingly, this fertilization-induced accumulation pattern was also observed for other genes involved in transcriptional repression but not for a MYST-family histone acetyltransferase. The strong increase in ScHD2a mRNA levels in ovules after fertilization suggests an important and localized role for transcriptional repression in seed development, and indicates why silencing of the AtHD2a gene leads to aborted seed formation.
