The Colletotrichum orbiculare SSD1 mutant enhances Nicotiana benthamiana basal resistance by activating a mitogen-activated protein kinase pathway.

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
Plant basal resistance is activated by virulent pathogens in susceptible host plants. A Colletotrichum orbiculare fungal mutant defective in the SSD1 gene, which regulates cell wall composition, is restricted by host basal resistance responses. Here, we identified the Nicotiana benthamiana signaling pathway involved in basal resistance by silencing the defense-related genes required for restricting the growth of the C. orbiculare mutant. Only silencing of MAP Kinase Kinase2 or of both Salicylic Acid Induced Protein Kinase (SIPK) and Wound Induced Protein Kinase (WIPK), two mitogen-activated protein (MAP) kinases, allowed the mutant to infect and produce necrotic lesions similar to those of the wild type on inoculated leaves. The fungal mutant penetrated host cells to produce infection hyphae at a higher frequency in SIPK WIPK-silenced plants than in nonsilenced plants, without inducing host cellular defense responses. Immunocomplex kinase assays revealed that SIPK and WIPK were more active in leaves inoculated with mutant fungus than with the wild type, suggesting that induced resistance correlates with MAP kinase activity. Infiltration of heat-inactivated mutant conidia induced both SIPK and WIPK more strongly than did those of the wild type, while conidial exudates of the wild type did not suppress MAP kinase induction by mutant conidia. Therefore, activation of a specific MAP kinase pathway by fungal cell surface components determines the effective level of basal plant resistance.
