A nucleoside diphosphate kinase gene OsNDPK4 is involved in root development and defense responses in rice (Oryza sativa L.).
Article in Planta, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
MAIN
conclusionDysfunctional mutation of OsNDPK4 resulted in severe defects in root development of rice. However, the resistance of Osndpk4 against bacterial blight was significantly enhanced. Nucleoside diphosphate kinases (NDPKs) are an evolutionarily conserved family of important enzymes balancing the energy currency nucleoside triphosphates by catalyzing the transfer of their phosphate groups. The aim of this study was to elucidate the function of OsNDPK4 in rice. A dysfunctional rice mutant was employed to characterize the function of OsNDPK4. Its expression and subcellular localization were examined. The transcriptomic change in roots of Osndpk4 was analyzed by RNA-seq. The rice mutant Osndpk4 showed severe defects in root development from the early seedling stage. Further analysis revealed that meristematic activity and cell elongation were significantly inhibited in primary roots of Osndpk4, together with reduced accumulation of reactive oxygen species (ROS). Map-based cloning identified that the mutation occurred in the OsNDPK4 gene. OsNDPK4 was found to be expressed in a variety of tissues throughout the plant and OsNDPK4 was located in the cytosol. Osndpk4 showed enhanced resistance to the bacterial pathogen Xanthomonas oryzae pv. oryzae (Xoo) and up-regulation of pathogenesis-related marker genes. In addition, transcriptomic analysis showed that OsNDPK4 was significantly associated with a number of biological processes, including translation, protein modification, metabolism, biotic stress response, etc. Detailed analysis revealed that the dysfunction of OsNDPK4 might reorchestrate energy homeostasis and hormone metabolism and signalling, resulting in repression of translation, DNA replication and cell cycle progression, and priming of biotic stress defense. Our results demonstrate that OsNDPK4 plays important roles in energy homeostasis, development process, and defense responses in rice.
