Transcriptomic analysis of Phytophthora infestans races and evaluation of their pathogenicity on potato.
Article in BMC plant biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Phytophthora infestans causes potato late blight and significantly impacts potato production. The pathogen's remarkable adaptability and ability to generate new physiological races through virulence variation undermine varietal resistance, posing challenges for disease prevention and control. To explore the genetic mechanisms behind these, different physiological races of P. infestans were inoculated on potato leaves and assayed through transcriptomics combined with metabolic profiling methods. It was found that the DL04 strain, which carries virulence factor 3, exhibited a high level of pathogenicity. Biologically, DL04 showed more rapid growth and denser mycelial structures compared to most other strains, indicating enhanced pathogenicity. DL04 induced a greater enrichment of carbon metabolism, biosynthesis of amino acids, and glycolysis/gluconeogenesis pathways during the infection process. This led to the upregulation of genes related to cell hydrolysis, accelerating leaf infection and contributing to its higher level of pathogenicity. The reasons for the differences in pathogenicity among different physiological races of P. infestans were clarified at the transcriptional level. This finding provides valuable insights into the genetic basis of P. infestans pathogenicity and offer critical information for developing effective control strategies, breeding for disease resistance, and improving potato production practice.
