Profiling methyl jasmonate-responsive transcriptome for understanding induced systemic resistance in whitebark pine (Pinus albicaulis).

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
key messageRNA-seq analysis on whitebark pine needles demonstrated that methyl jasmonate (MeJA)-triggered transcriptome re-programming substantially overlapped with defense responses against insects and fungal pathogens in Pinus species, increasing current knowledge regarding induced systemic resistance (ISR) to pathogens and pests in whitebark pine. Many whitebark pine populations are in steep decline due to high susceptibility to mountain pine beetle and the non-native white pine blister rust (WPBR). Resistance, including induced systemic resistance (ISR), is not well characterized in whitebark pine, narrowing the current options for increasing the success of restoration and breeding programs. Exogenous jasmonates are known to trigger ISR by activating the plant's immune system through regulation of gene expression to produce chemical defense compounds. This study reports profiles of whitebark pine needle transcriptomes, following methyl jasmonate (MeJA) treatment using RNA-seq. A MeJA-responsive transcriptome was de novo assembled and transcriptome profiling identified a set of differentially expressed genes (DEGs), revealing 1422 up- and 999 down-regulated transcripts with at least twofold change (FDR corrected p < 0.05) in needle tissues in response to MeJA application. GO analysis revealed that these DEGs have putative functions in plant defense signalling, transcription regulation, biosyntheses of secondary metabolites, and other biological processes. Lineage-specific expression of defense-related genes was characterized through comparison with MeJA signalling in model plants. In particular, MeJA-triggered transcriptome re-programming substantially overlapped with defense responses against WPBR and insects in related Pinus species, suggesting that MeJA may be used to improve whitebark pine resistance to pathogens/pests. Our study provides new insights into molecular mechanisms and metabolic pathways involved in whitebark pine ISR. DEGs identified in this study can be used as candidates to facilitate identification of genomic variation contributing to host resistance and aid in breeding selection of elite genotypes with better adaptive fitness to environmental stressors in this endangered tree species.
