Pyramiding the antimicrobial PR1aCB and AATCB genes in 'Tarocco' blood orange (Citrus sinensis Osbeck) to enhance citrus canker resistance.
Article in Transgenic research, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Citrus canker, caused by Xanthomonas citri subsp. citri (Xcc), is a major bacterial disease responsible for substantial economic losses in citrus-producing areas. To breed transgenic citrus plants with enhanced resistance to citrus canker, two antimicrobial peptide genes, PR1aCB and AATCB, were incorporated into 'Tarocco' blood orange (Citrus sinensis Osbeck) plants via co-transformation and sequential re-transformation. The presence of PR1aCB and AATCB in double transgenic plants was confirmed by PCR. The expression of PR1aCB and AATCB in double transformants was demonstrated by quantitative real-time PCR. An in vivo disease resistance assay involving the injection of Xcc revealed that the double transformants were more resistant to citrus canker than the single gene transformants and wild-type plants. An analysis of the bacterial population indicated that the enhanced citrus canker resistance of the double transformants was due to inhibited Xcc growth. These results proved that the pyramiding of multiple genes is a more effective strategy for increasing the disease resistance of transgenic citrus plants than single gene transformations.
