Identification and expression analysis of P-type ATPase IIIA subfamily in Puccinia Striiformis f. sp. tritici.
Article in BMC genomics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPuccinia striiformis f. sp. tritici (Pst) causes wheat stripe (yellow) rust disease, which is one of the most destructive diseases affecting wheat worldwide. ATPases, a class of membrane proteins, play an important role in material exchange and signal transduction both within and outside biological cells by transporting ions and phospholipids. In plant pathogens, P-type ATPases primarily participate in pathogen development and virulence regulation. However, the P-type ATPase of subfamily IIIA (PMA) has not yet been identified in Pst. To investigate the potential functions of the PMA gene family in Pst, we conducted a genome-wide bioinformatics analysis and examined the expression profiles of the PMA gene family.
resultsSix PMA genes were identified in the genome of P. striiformis f. sp. tritici (CYR34 race). The PMA proteins encoded by these genes ranged in length from 811 to 960 amino acids (aa). Each of the six PMA genes contained a typical ATPase IIIA H superfamily domain and was distributed across four chromosomes. Thirty-six major cis-regulatory elements were detected within the PMA gene family members. Elements such as the CGTCA-motif and TGACG-motif play significant roles in responding to environmental stresses and hormone signals. Quantitative PCR analysis revealed that the expression of the PMA04 gene was generally higher at 9 °C under various temperature stresses. The PMA06 gene typically exhibited higher expression levels at 16 °C. During the infection of Pst, the expression levels of PMA04, PMA05, and PMA06 were elevated at 72 h post treatment.
conclusionsOur results indicate that the PMA gene family in the CYR34 strain comprises six PMA genes, which are crucial for managing temperature stress and pathogen infection, and exhibit a distinctive splicing pattern. This study not only identifies a target and direction for the development of new, efficient, and environmentally friendly control agents for wheat stripe rust but also establishes a foundation for analyzing its pathogenic mechanisms.
