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

backgroundPowdery mildews (Erysiphaceae, Ascomycota) belong to the most important plant pathogenic fungi that cause stress to forest and fruit trees and lead to a considerable loss of economic crops worldwide as well as in Taiwan. The checklist of Erysiphaceae in Taiwan is an important basis to control these pathogens. However, it has been published 25 years ago without any updating, while taxonomic concepts of genera and species changed and many new fungus and host records have been published. We update the checklist of Erysiphaceae by applying new taxonomical concepts and we add several new host records worldwide or for Taiwan based on own, recent collections.

resultsThe updated checklist of powdery mildew in Taiwan is presented including data on 13 species of Erysiphaceae on 28 species of host plants. Doubtful records are marked as such and proposed for further investigation. For agricultural application, information on the usage of host plants was added to the checklist. Besides, over twenty specimens of Erysiphaceae on common plants in Taiwan recently collected by the authors were identified based on ITS sequences and anamorphic morphology. Among the collections, twelve represented new host records worldwide, while seventeen were new host records for Taiwan. Six species of Erysiphaceae were found in Taiwan for the first time.

conclusionsThe checklist of Erysiphaceae in Taiwan is an important basis for taxonomic and biogeographical studies as well as for quarantine sanctions referring to powdery mildews. Our results reveal that the host spectra of these pathogens are still incompletely known worldwide. Moreover, the list includes some doubtful old records that might be synonyms or wrong identifications. Morphological characteristics and ITS sequences are usually useful for the identification of Erysiphaceae. Several species in certain genera, however, cannot be distinguished since the variation in sequence data of those closely related species is quite low. New collections and re-investigation of old specimens are imperative to clarify some doubtful records.
