Genome-wide analysis of long noncoding RNAs in response to drought stress in the seeds of Brassica napus.

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
backgroundLong noncoding RNAs (lncRNAs) have been shown to play important roles in plant abiotic stress response and adaptation. However, the identification and characterization of genome-wide drought-responsive lncRNAs in rapeseed (Brassica napus L.) have been limited. Therefore, this study was the first to identify the expression profile of lncRNAs in rapeseed seeds responding to prolonged drought stress and subsequent short-term rewatering.
resultsA total of 6 000 lncRNAs were identified, among which 181 were classified as differentially expressed lncRNAs (DELs) in response to either drought stress or subsequent rewatering. Comparative analysis revealed that only 14 DELs were shared between the 159 DELs identified during drought stress and the 27 DELs detected upon rewatering. GO enrichment analysis showed that the co-expressed DEGs, primarily involved in photosynthesis, central carbon metabolism, stomatal movement, and strigolactone metabolism, were significantly down-regulated under drought stress but markedly up-regulated in subsequent rewatering. Furthermore, drought‑responsive competing endogenous RNA (ceRNA) networks were constructed based on the identified DETs and DEGs. Two ceRNA modules, MSTRG.57345.1-bna-miR164a/b/c/d-HSP2 and MSTRG.57345.1-bna-miR395d/e/f-HSFA7a, which are based on the newly identified lncRNA MSTRG.57345.1, were detected for the first time in rapeseed under drought stress and subsequent rewatering.
conclusionsThe present study advances our understanding of the expression patterns and functional role of rapeseed lncRNAs in the response to drought stress and the subsequent rewatering. It provides novel insights into lncRNA-mRNA networks and lncRNA-miRNA-mRNA networks in the seeds of B. napus. These findings offer a valuable reference for further genetic research and molecular breeding programs aimed at rapeseed improvement.
