Project description:MicroRNAs (miRNAs) are a class of non-coding small RNAs (sRNAs) that play crucial regulatory roles in various developmental processes. Silique length indirectly influences seed yield in rapeseed (Brassica napus); however, the molecular roles of miRNAs in silique length are largely unknown. Here, backcross progenies of rapeseed with long siliques (LS) and short siliques (SS) were used to elucidate this role. Four small RNA libraries from early developing siliques were sequenced, and a total of 814 non-redundant miRNA precursors were identified, representing 65 known miRNAs, and 394 novel miRNAs. Expression analyses revealed 12 known miRNAs and 5 novel miRNAs that were differentially expressed in LS and SS lines. Furthermore, though two degradome sequencing, we annotated 522 cleavage events. An analysis of correlated expression between differentially expressed miRNAs and their targets demonstrated that some transcription factors might repress cell proliferation or auxin signal transduction to control silique length, and that a Pi/Cu deficiency might also restrict silique development. More significantly, the overexpression of miR160 in rapeseed may repress auxin response factors and result in increased silique length, illustrating that silique length could be regulated via an auxin-response pathway. These results will serve as a foundation for future research in B. napus.

Project description:This study investigates the transcriptome and physiological responses of rapeseed to post-flowering temperature increases, providing valuable insights into the molecular mechanisms underlying rapeseed tolerance to heat stress. Two rapeseed genotypes, Lumen and Solar, were assessed under control and heat stress conditions in field experiments conducted in Valdivia, Chile. Results showed that seed yield and seed number were negatively affected by heat stress, with genotype-specific responses. Lumen exhibited a 9.3% average seed yield reduction, while Solar showed a 28.7% reduction. RNA-seq analysis of siliques and seeds revealed tissue-specific responses to heat stress, with siliques being more sensitive to temperature stress. Hierarchical clustering analysis identified distinct gene clusters reflecting different aspects of heat stress adaptation in siliques, with a role for protein folding in maintaining silique development and seed quality under high temperature conditions. In seeds, three distinct patterns of heat-responsive gene expression were observed, with genes involved in protein folding and response to heat showing genotype-specific expression. Gene coexpression network analysis revealed major modules for rapeseed yield and quality, as well as the trade-off between seed number and seed weight. Overall, this study contributes to understanding the molecular mechanisms underlying rapeseed tolerance to heat stress and can inform crop improvement strategies targeting yield optimization under changing environmental conditions.

Project description:Both of Histone Deacetylases HDA6 and HDA9 belong to RPD3/HDA1 class I subfamily, and they have similar protein structure. Loss of function of HDA9 display a blunt silique. Although there is not protein-protein interaction between HDA6 and HDA9, they simultaneously loss function led to “nock-shape” silique that more seriously silique phenotype than hda9. The silique valve cell of hda9 and hda6 hda9 were longer than wild type and hda6. The transcripts level of auxin signaling related genes were mis-regulated in hda9 and hda6 hda9 silique, and GFP signaling derived by auxin response promoter DR5 were weaker in hda9 and hda6 hda9 than wild type and hda6. Thus, our findings reveal that HDA6 and HDA9 coordinately control silique valve cell elongation through affecting auxin signaling related genes expression in silique.

Project description:Enhanced recovery after surgery (ERAS) has been reported to be associated with improved outcomes in many studies, most of which involve short-term effects. Only a few studies have reported the long-term effects of highly compliant ERAS. However, to the best of our knowledge, there are no large-scale comparisons between incomplete ERAS (compliance < 70%) and non-ERAS. The aim of this comparative study is to analyze and evaluate the long-term outcomes of incomplete ERAS in laparoscopic colorectal cancer surgery.

Project description:Purpose: Analysis of the effect of different fats and amonut of cDDGS in the feedstuff on miRNA expression in porcine backfat Methods: miRNA-seq analysis was performed on backfat samples collected from 24 male and female crossbred fatteners originating from sows (Polish Landrace × White Large Polish) mated with a boar (Duroc × Pietrain) divided into four dietary groups: 7-cDDGS+rapeseed oil (group I), n=6 (+cDDGS+rapeseed oil -group II), n= 6 (+cDDGS+beeftallow -group III),n=5 (+cDDGS+coconut oil -group IV). The miRNA libraries were constructed from total RNA using NEBNext Multiplex Small RNA Library Prep Set for Illumina (New England Biolabs) according to the manufacturer protocol. The quantification of the obtained libraries was performed on a Qubit 2.0 spectrophotometer (Invitrogen, Life Technologies), while a quality control on a TapeStation 2200 instrument (D1000 ScreenTape; Agilent). 100 single-end cycle sequencing was performed on the HiScanSQ platform (Illumina) with the use of TruSeq SR Cluster Kit v3- CBOT-HS and TruSeq SBS Kit v 3 - HS (Illumina). MicroRNA differentially expressed between dietary groups were identified with the DESeq2 software. Results: The comparison of miRNA profiles between dietary groups showed The highest number of miRNAs with altered expression was identified in the comparison of animals fed the diet containing cDDGS and coconut oil (group IV) with animals from the –cDDGS + rapeseed oil (group I) (37 miRNA, p adjusted <0.01). Moreover, in comparison between the group IV and groups III and II , 29 (12 upregulated and 17 downregulated in +cDDGS+coconut oil group) and 28 (10 upregulated and 18 downregulated in +cDDGS+coconut oil group) miRNAs were identified, respectively (p adjusted <0.1) Conclusions: Obtained results suggest that coconut oil induces changes in miRNA profile of backfat in pigs.
