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

Little is known about the genes expressed during grapevine somatic embryogenesis. Both groups of Somatic Embryogenesis Receptor Kinase (SERK) and Leafy Cotyledon (LEC and L1L) genes seem to play key roles during somatic embryogenesis in various plant species. Therefore, we identified and analysed the sequences of VvSERK and VvL1L (Leafy cotyledon1-Like) genes. The deduced amino acid sequences of VvSERK1, VvSERK2 and VvSERK3 are very similar to that of registered SERK proteins, with highest homologies for the kinase domain in the C-terminal region. The amino acid sequence of VvL1L presents all the domains that are characteristic for LEC1 and L1L proteins, particularly, the 16 amino acid residues that serve as signature of the B-domain. Phylogenetic analysis distinguishes members of subclass LEC1 and subclass L1L, and VvL1L is closely related to L1L proteins. Using semi-quantitative RT-PCR, we studied gene expression of VvSERK1, VvSERK2, VvSERK3 and VvL1L in calli and somatic embryos obtained from anther culture of Vitis vinifera L. cv Chardonnay. Expression of VvSERK2 is relatively stable during in vitro culture. In contrast, VvSERK1, VvSERK3 and VvL1L are expressed more 4 to 6 weeks after transfer of the calli onto embryo induction medium, before the visible appearance of embryos on the calli as seen by environmental scanning electron microscopy. Later on (8 weeks after transfer) VvSERK1 expression is maintained in the embryogenic calli and VvSERK3 in the embryos, whereas VvL1L expression is very low. All together, these data suggest the involvement of VvSERK and VvL1L genes in grapevine somatic embryogenesis.
