Genomic and Transcriptomic Analyses Provide Insights Into Erysiphe necator Pathogenicity and Grapevine Response.

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
Grapevine powdery mildew, caused by the fungus Erysiphe necator, is one of the most prevalent obligate biotrophic pathogens in vineyards, posing a significant threat to grape production. Despite its impact, research on E. necator pathogenicity and grapevine responses remains limited. In this study, we assembled a high-quality 69.93 Mb genome for E. necator isolate NAFU1, identifying 248 candidate-secreted effector proteins (CSEPs). RNA-Seq analysis of E. necator NAFU1 and the grapevine host during various infection stages revealed that expression of many genes, especially those encoding CSEPs, was induced in planta to facilitate host colonisation. Detailed analysis identified CSEP118 as a key highly induced effector gene, plays an important role in suppression of host defence. CSEP118 appears to interfere with the grapevine defence response to infection by targeting VviTrxz, a grapevine thioredoxin. Comparative transcriptome analysis of susceptible (Vitis vinifera cv. Cabernet Sauvignon) and resistant (Vitis piasezkii accession Baishui-40) grapevines upon infection by E. necator identified VviTCP14, encoding a transcription factor, to be a likely negative regulator of grapevine resistance against E. necator. Supporting this, VviTCP14-silenced plants exhibited increased expression of resistance-related genes such as those encoding stilbene synthases (STSs) and elevated stilbene contents when compared with the wild type grapevine. In summary, this study utilised a multi-omics approach to understand mechanisms underlying E. necator effector-triggered suppression of grapevine immunity and transcriptional regulation of host defence response during grapevine-powdery mildew interaction. The regulatory mechanisms uncovered in this study should provide valuable insights for improving grapevine resistance to powdery mildew.
