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

Photosynthetic microalgae are promising green cell factories for the sustainable production of high-value chemicals and biopharmaceuticals. The chloroplast organelle is being developed as a chassis for synthetic biology as it contains its own genome (the plastome) and some interesting advantages, such as high recombinant protein titers and a diverse and dynamic metabolism. However, chloroplast engineering is currently hampered by the lack of standardized cloning tools and Design-Build-Test-Learn workflows to ease genomic and metabolic engineering. The MoClo (Modular Cloning) toolkit based on Golden Gate assembly was recently developed in the model eukaryotic green microalgae Chlamydomonas reinhardtii to facilitate nuclear transformation and engineering. Here, we present MoCloro as an extension of the MoClo that allows chloroplast genome engineering. Briefly, a Golden Gate-compatible chloroplast transformation vector (pWF.K.4) was constructed, which contains homologous arms for integration at the petA site in the plastome. A collection of standardized parts (promoters, terminators, reporter and selection marker genes) was created following the MoClo syntax to enable easy combinatorial assembly of multi-cassettes in the destination pWF.K.4 vector. The functionality of the biobricks was assayed by constructing and assessing the expression of several multigenic constructs. Finally, a generic vector pK4 was constructed for easy Golden Gate cloning of 5' and 3' homologous arms, allowing targeting at alternative plastome integration sites. This work represents a significant advancement in technology aimed at facilitating more efficient and rapid chloroplast transformation and engineering of green microalgae.
