A comprehensive exploration of molecular aspects of rice-Ustilaginoidea virens interactions.
Review in Plant molecular biology, 2026. 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
Rice false smut (RFS) caused by Ustilaginoidea (U.) virens has become an emerging threat to global rice production, driven by complex host-pathogen interactions and stage-specific infection processes. We present a comprehensive review of the omics approach to delve into the interplay of genes and their functional validation in decoding the pathway of infection by U. virens and the resistance mechanism exhibited by rice. Firstly, the pathogenesis genes are discussed, which are triggered at spore germination, progressing to hyphal colonization of floral tissues and smut ball formation. Furthermore, these processes are a consequence of tightly regulated expression of genes of different pathways such as cAMP-MAPK signaling, transcriptional regulators, cell wall integrity factors, virulence determinants, secondary metabolites, and carbohydrate-active enzymes. The rice plants also respond by activating a plethora of defense genes such as phytoalexin biosynthesis, pathogenesis-related proteins, receptor-like kinases, transcription factors, anti-oxidation, etc. The mapping of these genes to related quantitative trait loci and short sequence repeat sequences may aid in gene pyramiding strategies for molecular-assisted breeding programs. The molecular manipulation of resistance genes using CRISPR-Cas9 may further facilitate targeted development of improved rice varieties. Overall, molecular insights of host-pathogen interactions offer decoding of sustainable strategies for developing resilient cultivars and effective management of false smut disease.
