Low-affinity iron transport protein Uvt3277 is important for pathogenesis in the rice false smut fungus Ustilaginoidea virens.

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
Ustilaginoidea virens is the causal agent of rice false smut disease resulting in quantitative and qualitative losses in rice. To gain insights into the pathogenic mechanisms of U. virens, we established a T-DNA insertion mutant library of U. virens through Agrobacterium tumefaciens-mediated transformation and selected an enhanced pathogenicity mutant (i.e., B3277). We analyzed the biological characteristics of the wild-type P1 and B3277. The growth rate and sporulation of B3277 were decreased compared with those of P1; the ferrous iron could be utilized by B3277, but inhibited the growth of P1. Southern blot analysis was performed to verify the copy number of the foreign gene inserted in the genomic DNA and only one copy of the T-DNA was found. The combined hiTAIL-PCR with RACE-PCR analysis showed the successful cloning of full length of the T-DNA flanking gene associated with pathogenicity, named Uvt3277. Gene expression was analyzed using real-time PCR. Results revealed that Uvt3277 was expressed at lower levels in B3277 than in P1. This gene was then subjected to bioinformatics analysis. The encoded protein of Uvt3277 exhibited high homology with low-affinity iron transporter proteins in some fungi. Transformation of the RNAi vector by constructing the hairpin RNA of the target gene was confirmed as successful. The pathogenicity of the transformant also increased. These results suggested that Uvt3277 may have an important function associated with the pathogenesis of U. virens. This study provides insights into the pathogenic mechanism of U. virens and a molecular target of disease control.
