1 · What the graph read from it

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.

2 · The registry

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

Brachypodium distachyon is a novel model system for structural and functional genomics studies of temperate grasses because of its biological and genetic attributes. Recently, the genome sequence of the community standard line Bd21 has been released and the availability of an efficient transformation system is critical for the discovery and validation of the function of Brachypodium genes. Here, we provide an improved procedure for the facile and efficient Agrobacterium-mediated transformation of line Bd21. The protocol relies on the transformation of compact embryogenic calli derived from immature embryos using visual and chemical screening of transformed tissues and plants. The combination of green fluorescent protein expression and hygromycin resistance enables early identification of transformation events and drastically reduces the quantity of tissue to be handled throughout the selection process. Approximately eight independent fully developed transgenic Bd21 plants can be produced from each immature embryo, enabling the generation of thousands of T-DNA lines. The process--from wild-type seeds to transgenic T(1) seeds--takes approximately 8 months to complete.
