Expression and function analysis of a rice OsHSP40 gene under salt stress.
Article in Genes & genomics, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 17 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
Heat shock proteins (HSPs) play essential roles in both plant growth and abiotic stress tolerance. In rice, OsHSP40 was recently reported to regulate programmed cell death (PCD) of suspension cells under high temperature. However, the expression and functions of OsHSP40 under normal growth or other abiotic stress conditions is still unknown. We reported the expression and function of a rice OsHSP40 gene under salt stress. Homologous proteins of OsHSP40 were collected from the NCBI database and constructed the neighbor-joining (NJ) phylogenetic tree. The expression pattern of OsHSP40 was detected by qRT-PCR under NaCl (150 mM) treatment. Then, identified a rice T-DNA insertion mutant oshsp40. At last, we compared and analyzed the phenotypes of oshsp40 and wild type under salt stress. OsHSP40 was a constitutively expressed small HSP (sHSP) gene and was close related to other plant sHSPs. Moreover, the expression of OsHSP40 was regulated by salt, varying across time points and tissues. Furthermore, the growth of T-DNA insertion mutant of OsHSP40 (designated as oshsp40) was suppressed by NaCl (150 mM) compared with that of the WT at seedling stage. Detailed measurement showed root and shoot length of the oshsp40 seedlings were significantly shorter than those of the WT seedlings under NaCl stress. In addition, the pot experiment results revealed that seedlings of oshsp40 withered more seriously compared with those of WT after NaCl treatment and recovery, and that survival rate and fresh weight of oshsp40 seedlings were significantly reduced. Taken together, these data suggested that OsHSP40 had multiple functions in rice normal growth and abiotic stress tolerance.
