Project description:Extreme weather events, such as heatwaves, are becoming increasingly frequent, long-lasting, and severe as global climate change continues, shaping marine biodiversity patterns worldwide. Increased risk of overheating and mortality across major taxa have been recurrently observed, jeopardizing the sustainability of ecosystem services. Molecular responses of species, which scale up to physiological and population responses, are determinant processes that modulate species sensitivity or tolerance to extreme weather events. Here, we analysed the whole-body proteome of the intertidal ragworm Hediste diversicolor (Müller, 1776), a keystone species in estuarine ecosystems and an emergent blue bio-resource, to long-lasting heatwaves (24 ºC vs 30 ºC for 1 month). We hypothesized that this species is phenotypically plastic and thus able to acclimate to heatwaves by inducing cytoprotective pathways and modulating energy metabolism to enhance its thermal tolerance and maintain survival. To test these hypotheses, worms were exposed to control (24 ºC) and a +6 ºC increase in water temperature (30 ºC) for a month, after which they were collected for whole-body proteomic (after 28 days of exposure) analysis. Concomitantly, fatty acid analysis (after 28 days of exposure) and cumulative survival, upper thermal tolerance limits and wet weight (after 30 days of exposure) were compared between control and heatwave exposed worms.

Project description:Rose (Rosa hybrida L.) is a major cut flowers in the world. Studying the molecular mechanism of auxin regulation in growth is of great significance for enhancing the understanding of the growth and development processes of rose and informing accurate exogenous auxin application in rose production. However, the response mechanism of rose to miRNA-mediated auxin signal transduction is unclear. In this study, rose plants were treated with IAA, and 75 known miRNAs and 168 novel miRNAs were identified by small RNA sequencing. Among them, 19 known miRNAs and 42 miRNAs were differentially expressed. Many differential miRNAs demonstrated staged responses to auxin treatment. The targeted relationship between miRNA and key transcription factors regulated by auxin in rose was analyzed, and the target genes in the ARF family and AUX/IAA family were screened. By using quantitative real-time PCR(qRT-PCR) to verify the expression patterns of the miRNA regulating the auxin signal transduction pathway and its target gene, we found that miR156a, miR160a, miR164a, miR167d, miR396b-3p, novel_miR_189, novel_miR_74, novel_miR_8, and novel_miR_207 interacted negatively with the ARF family, and miR390a-3p and novel_miR_101 interacted negatively with the AUX/IAA family. These results provide a theoretical basis for further studies on the auxin regulatory mechanisms in rose.

Project description:MicroRNAs (miRNAs) are small non-coding RNAs that regulate target mRNAs by inducing degradation or preventing translation of their target mRNAs. Rose, Rosa rugosa Thunb., is an important ornamental and edible plant, yet there are only a few studies on the miRNAs of rose. Here we carried out computational and experimental analysis of miRNAs and phased small interfering RNAs (phasiRNAs) in rose by analyzing 10 small RNA profiles from roots, petals, pollens, stamens, and leaves. To identify the targets of miRNAs and phasiRNAs, we generated a degradome profile for rose leaf which is analyzed using the SeqTar algorithm. This study identified 25 conserved pre-miRNAs, of which 24 have not been reported previously. We also found 22 novel pre-miRNAs. Three hundred and thirty nine 21 nucleotide (nt) PHAS loci, and forty nine 24 nt PHAS loci were also identified. We identified more than 4000 putative targets of the conserved miRNAs using a criteria of less than 4 mismatches between miRNA and targets. Among these targets, at least 171 have shown significant accumulation of degradome reads. Our results demonstrate that the miR482 family triggers the generations of phasiRNAs by targeting nucleotide-binding, leucine-rich repeat (NB-LRR) disease resistance genes in rose. These results significantly enhanced our knowledge of the miRNAs and phasiRNAs, as well as their potential functions in rose.
