Abstract Chrysanthemum ( morifolium Ramat.) is a globally important ornamental plant with great economic, cultural, and symbolic value. However, research on chrysanthemum challenging due to its complex genetic background. Here, we report near-complete assembly annotation for C. comprising 27 pseudochromosomes (8.15 Gb; scaffold N50 of 303.69 Mb). Comparative evolutionary analyses reveal whole-genome triplication (WGT) event shared by species approximately 6 million years ago (Mya) the...
Abstract Background N 6 -methyladenosine (m A) is a prevalent and conserved RNA modification in eukaryotes. While its roles the 3’ untranslated regions (3’ UTR) are well-studied, role 5' UTR relationship with histone modifications remain underexplored. Results We demonstrate that m A methylation 5’ of mRNA triggers downstream shift H3K4me3 modification. This regulatory mechanism Arabidopsis , rice, chrysanthemum. The observed genetically controlled by modifiers influences gene expression....
Background Simple sequence repeats (SSRs) are ubiquitous in eukaryotic genomes. Chrysanthemum is one of the largest genera Asteraceae family. Only few expressed tag (EST) sequences have been acquired to date, so number available EST-SSR markers very low. Methodology/Principal Findings Illumina paired-end sequencing technology produced over 53 million reads from C. nankingense mRNA. The subsequent de novo assembly yielded 70,895 unigenes, which 45,789 (64.59%) unigenes showed similarity NCBI...
The gene encoding the MYB (v-myb avian myeloblastosis vira l oncogene homolog) transcription factor CmMYB19 was isolated from chrysanthemum. It encodes a 200 amino acid protein and belongs to R2R3-MYB subfamily. not transcriptionally activated in yeast, while transient expression experiment conducted onion epidermal cells suggested that product localized nucleus . induced by aphid (Macrosiphoniella sanborni) infestation, abundance of transcript higher leaf stem than root. over-expression...
Flavones are among the major colorless pigments synthesized through branches of flavonoid pathway in plants. However, due to absence a gene encoding flavone synthase (FNS) model plant Arabidopsis thaliana species, regulatory mechanism FNS-catalyzed biosynthesis has rarely been studied Here, it was found that flavones play predominant role elimination excess reactive oxygen species (ROS) at high temperatures organs. A novel atypical subgroup 7 (SG7) R2R3-MYB transcription factor, CmMYB012, be...
Chrysanthemum, one of the most important commercial ornamental crops, is susceptible to salinity, which limits its cultivation and application in coastal inland saline areas. Grafting widely used improve salt tolerance horticultural but mechanisms grafted chrysanthemum responses stress remain unclear. In this study, we showed that heterografted chrysanthemums with Artemisia annua as rootstock exhibited increased compared self-grafted self-rooted chrysanthemums. Under high stress, roots...
Heat shock proteins are associated with protection against various abiotic stresses. Here, the isolation of a chrysanthemum cDNA belonging to HSP70 family is reported. The cDNA, designated CgHSP70, encodes 647-residue polypeptide, estimated molecular mass 70.90 kDa and pI 5.12. A sub-cellular localization assay indicated that product deposited in cytoplasm nucleus. performance Arabidopsis thaliana plants constitutively expressing CgHSP70 demonstrated gene enhances tolerance heat, drought...
A major constraint affecting the quality and productivity of chrysanthemum is unusual period low temperature occurring during early spring, late autumn, winter. Yet, there has been no systematic investigation on genes underlying response to in chrysanthemum. Herein, we used RNA-Seq platform characterize transcriptomic by comparing different transcriptome Chrysanthemum nankingense plants subjecting them a sub-zero temperature, with or without prior acclimation. Six separate libraries were...
Summary Salinity‐induced Na + toxicity and oxidative stress hamper plant growth. Here, we showed that expression of the chrysanthemum Cm HSFA 4 , a homologue heat‐shock factor At 4a is inducible by salt localizes to nucleus. It transcription activator binding with HSE . Chrysanthemum overexpressing displayed enhanced salinity tolerance limiting accumulation while maintaining K concentration, which consistent up‐regulation ion transporters SOS 1 HKT 2 Additionally, transgenic plants reduced H...
MYB transcription factors are widely involved in the development of and physiological processes plants. Here, we isolated chrysanthemum R2R3-MYB family factor CmMYB15, a homologous gene AtMYB15. It was demonstrated that CmMYB15 expression induced by aphids could bind to AC elements, which usually exist promoter lignin biosynthesis genes. Overexpression enhanced resistance aphids. Additionally, content several genes increased. In summary, results indicate regulates enhance
ICE (Inducer of CBF Expression) family genes play an important role in the regulation cold tolerance pathways. In earlier study, we isolated gene CdICE1 from Chrysanthemum dichrum and demonstrated that freezing was enhanced by overexpression. Therefore, sought to determine mechanism which ICE1 participate tolerance.Using EMSA (Electrophoretic Mobility Shift Assay) yeast one-hybrid assays, confirmed binds specifically MYC element CdDREBa promoter activates transcription. addition,...
Summary For a flowering plant, the transition from vegetative stage to reproductive growth is probably most critical developmental switch. In model plant Arabidopsis thaliana , product of BBX7 group II member BBX family, acts delay floral transition. this study, presumed chrysanthemum homolog second gene AtBBX8 designated CmBBX8 had been isolated and characterized. The transcription followed diurnal rhythm as regulator. Overexpression accelerated flowering, while its (artificial microRNAs)...
The objective of this study was to identify the major volatile compounds and their relative concentrations in flowers different chrysanthemum cultivars wild relatives. organic components fresh were analyzed using a headspace solid-phase microextraction coupled with gas chromatography-mass spectrometry. In total, 193 detected; scent monoterpenoids oxygenated monoterpenoids, which accounted for 68.59%–99.93% total volatiles all tested materials except Chrysanthemum indicum collected from...
