[PMID: 38999704 PMCID: PMC11243879 DOI: 10.3390/plants13131865] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/17/2024] [Revised: 06/19/2024] [Accepted: 07/04/2024] [Indexed: 07/14/2024]
Abstract
Chrysanthemums are among the world's most popular cut flowers, with their color being a key ornamental feature. The formation of these colors can be influenced by high temperatures. However, the regulatory mechanisms that control the fading of chrysanthemum flower color under high-temperature stress remain unclear. This study investigates the impact of high temperatures on the color and biochemical responses of purple chrysanthemums. Four purple chrysanthemum varieties were exposed to both normal and elevated temperature conditions. High-temperature stress elicited distinct responses among the purple chrysanthemum varieties. 'Zi Feng Che' and 'Chrystal Regal' maintained color stability, whereas 'Zi Hong Tuo Gui' and 'Zi lian' exhibited significant color fading, particularly during early bloom stages. This fading was associated with decreased enzymatic activities, specifically of chalcone isomerase (CHI), dihydroflavonol 4-reductase (DFR), and anthocyanidin synthase (ANS), indicating a critical period of color development under heat stress. Additionally, the color fading of 'Zi Lian' was closely related to the increased activity of the peroxidase (POD) and polyphenol oxidase (PPO). Conversely, a reduction in β-glucosidase (βG) activity may contribute significantly to the color steadfastness of 'Zi Feng Che'. The genes Cse_sc027584.1_g010.1 (PPO) and Cse_sc031727.1_g010.1 (POD) might contribute to the degradation of anthocyanins in the petals of 'Zi Hong Tuo Gui' and 'Zi Lian' under high-temperature conditions, while simultaneously maintaining the stability of anthocyanins in 'Zi Feng Che' and 'Chrystal Regal' at the early bloom floral stage. The findings of this research provide new insights into the physiological and biochemical mechanisms by which chrysanthemum flower color responds to high-temperature stress.

Abstract
Autopolyploids often exhibit plant characteristics different from their diploid ancestors and are frequently associated with altered genes expression controlling growth and development. TCP is a unique transcription factor family in plants that is closely related to plant growth and development. Based on transcriptome sequencing of Chrysanthemum nankingense, 23 full-length TCP genes were cloned. The expression of CnTCP9 was most variable in tetraploids, at least threefold greater than diploids. Due to the lack of a C. nankingense transgenic system, we overexpressed CnTCP9 in Arabidopsis thaliana (Col-0) and Chrysanthemum morifolium. Overexpression of CnTCP9 caused enlargement of leaves in A. thaliana and petals in C. morifolium, and the expression of genes downstream of the GA pathway in C. morifolium were increased. Our results suggest that autopolyploidization of C. nankingense led to differential expression of TCP family genes, thereby affecting plant characteristics by the GA pathway. This study improves the understanding of enlarged plant size after autopolyploidization.

Abstract
BACKGROUND Flowers of Chrysanthemum × morifolium Ramat. are used as tea in traditional Chinese cuisine. However, with increasing population and urbanization, water and land availability have become limiting for chrysanthemum tea production. Hydroponic culture enables effective, rapid nutrient exchange, while requiring no soil and less water than soil cultivation. Hydroponic culture can reduce pesticide residues in food and improve the quantity or size of fruits, flowers, and leaves, and the levels of active compounds important for nutrition and health. To date, studies to improve the yield and active compounds of chrysanthemum have focused on soil culture. Moreover, the molecular effects of hydroponic and soil culture on chrysanthemum tea development remain understudied. RESULTS Here, we studied the effects of soil and hydroponic culture on yield and total flavonoid and chlorogenic acid contents in chrysanthemum flowers (C. morifolium 'wuyuanhuang'). Yield and the total flavonoids and chlorogenic acid contents of chrysanthemum flowers were higher in the hydroponic culture system than in the soil system. Transcriptome profiling using RNA-seq revealed 3858 differentially expressed genes (DEGs) between chrysanthemum flowers grown in soil and hydroponic conditions. Gene Ontology (GO) enrichment annotation revealed that these differentially transcribed genes are mainly involved in "cytoplasmic part", "biosynthetic process", "organic substance biosynthetic process", "cell wall organization or biogenesis" and other processes. Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis revealed enrichment in "metabolic pathways", "biosynthesis of secondary metabolites", "ribosome", "carbon metabolism", "plant hormone signal transduction" and other metabolic processes. In functional annotations, pathways related to yield and formation of the main active compounds included phytohormone signaling, secondary metabolism, and cell wall metabolism. Enrichment analysis of transcription factors also showed that under the hydroponic system, bHLH, MYB, NAC, and ERF protein families were involved in metabolic pathways, biosynthesis of secondary metabolites, and plant hormone signal transduction. CONCLUSIONS Hydroponic culture is a simple and effective way to cultivate chrysanthemum for tea production. A transcriptome analysis of chrysanthemum flowers grown in soil and hydroponic conditions. The large number of DEGs identified confirmed the difference of the regulatory machinery under two culture system.

Abstract
Saffron is a well-known Chinese traditional herb, and crocin biosynthesis is related to the yield and quality of saffron. This study aimed to screen differentially expressed genes (DEGs) in saffron at different flowering stages and identify cytochrome P450 (CYP) genes involved in crocin biosynthesis. Saffron samples at different flowering stages were used for RNA sequencing, and DEGs between the samples at three days before the flowering stage (- 3da) and two days after the flowering stage (+ 2da) were screened. Thereafter, significantly differentially expressed CYP genes were identified, and CYP gene expression at different flowering stages and in various tissues of saffron was determined using real-time quantitative polymerase chain reaction (RT-qPCR). After sequencing and analysis, 1508 DEGs between the samples at - 3da and + 2da were identified, including 487 upregulated and 1021 downregulated genes, which were enriched in 16 biological processes, 5 cellular components, 3 molecular functions, and 11 KEGG pathways, including protein processing in endoplasmic reticulum, pentose and glucuronate interconversions, starch and sucrose metabolism, estrogen signaling pathway, and mitogen-activated protein kinase signaling pathway. In addition, 12 significantly differentially expressed CYP genes were identified. The RT-qPCR results showed that CYP76C4, CYP72A15, CYP72A219, CYP97B2, CYP714C2, CYP71A1, CYP94C1, and CYP86A8 were all expressed in the pistils, and CYP72A219, CYP72A15, CYP97B2, CYP71A1, and CYP86A8 were highly expressed in the pistils. Our study established a transcriptome library of saffron and found that CYP72A219, CYP72A15, CYP97B2, CYP71A1, and CYP86A8 may be candidates involved crocin biosynthesis in saffron.

Abstract
BACKGROUND Orchardgrass (Dactylis glomerata L.) is a popular cool-season perennial grass with a high production value, and orchardgrass seed is the fourth top-selling forage grass seed in the world. However, its yield and quality are often affected by flooding. To date, the molecular responses of orchardgrass to flooding were poorly understood. RESULTS Here, we performed mRNA-seq to explore the transcriptomic responses of orchardgrass to a short term flooding (8 h and 24 h). There were 1454 and 565 differentially expressed genes identified in the 8 h and 24 h of flooding, respectively, compared to well control. GO functional enrichment analysis showed that oxidoreductase activity and oxidation-reduction process were highly present, suggesting that flooding induced the response to oxygen stress. Pathways enrichment analysis highlights the importance of glutathione metabolism, peroxidase, glycolysis and plant hormone signal transduction in response to flooding acclimation. Besides, the ROS clearance system is activated by significantly expressed glutathione S-transferase and genes encoding SOD and CAT (CAT1 and CDS2). The significant positive correlation between RNA sequencing data and a qPCR analysis indicated that the identified genes were credible. CONCLUSION In the process of orchardgrass response to flooding stress, multiple differential genes and biological processes have participated in its acclimation to flooding, especially the biological processes involved in the removal of ROS. These results provide a basis for further research on the adaptation mechanism of orchardgrass to flood tolerance.

Abstract
Chrysanthemum (Chrysanthemum morifolium Ramat.) is a leading flower with applied value worldwide. Developing new chrysanthemum cultivars with novel characteristics such as new flower colors and shapes, plant architectures, flowering times, postharvest quality, and biotic and abiotic stress tolerance in a time- and cost-efficient manner is the ultimate goal for breeders. Various breeding strategies have been employed to improve the aforementioned traits, ranging from conventional techniques, including crossbreeding and mutation breeding, to a series of molecular breeding methods, including transgenic technology, genome editing, and marker-assisted selection (MAS). In addition, the recent extensive advances in high-throughput technologies, especially genomics, transcriptomics, proteomics, metabolomics, and microbiomics, which are collectively referred to as omics platforms, have led to the collection of substantial amounts of data. Integration of these omics data with phenotypic information will enable the identification of genes/pathways responsible for important traits. Several attempts have been made to use emerging molecular and omics methods with the aim of accelerating the breeding of chrysanthemum. However, applying the findings of such studies to practical chrysanthemum breeding remains a considerable challenge, primarily due to the high heterozygosity and polyploidy of the species. This review summarizes the recent achievements in conventional and modern molecular breeding methods and emerging omics technologies and discusses their future applications for improving the agronomic and horticultural characteristics of chrysanthemum.

Abstract
Heat stress limits the growth of roses and adversely affects the yield and the quality of the rose cut-flowers. To investigate the heat stress response (HSR) mechanisms of rose, we compared the transcriptome profiling generated from Rosa chinensis 'Slater's crimson China' exposed to heat stress for five different time duration (0, 0.5, 2, 6, 12 h). Overall, 6175 differentially expressed genes (DGEs) were identified and exhibited different temporal expression patterns. Up-regulated genes related to chaperone-mediated protein folding, signal transduction and ROS scavenging were rapidly induced after 0.5-2 h of heat treatment, which provides evidence for the early adjustments of heat stress response in R. chinensis. While the down-regulated genes related to light reaction, sucrose biosynthesis, starch biosynthesis and cell wall biosynthesis were identified after as short as 6 h of heat stress, which indicated the ongoing negative effects on the physiology of R. chinensis. Using weighted gene co-expression network analysis, we found that different heat stress stages could be delineated by several modules. Based on integrating the transcription factors with upstream enriched DNA motifs of co-expressed genes in these modules, the gene regulation networks were predicted and several regulators of HSR were identified. Of particular importance was the discovery of the module associated with rapid sensing and signal transduction, in which numerous co-expressed genes related to chaperones, Ca2+ signaling pathways and transcription factors were identified. The results of this study provided an important resource for further dissecting the role of candidate genes governing the transcriptional regulatory network of HSR in Rose.

Abstract
The enzyme RNAPII CTD phosphatase-like 1 is known as a transcriptional regulator of the plant response to various abiotic stresses. Here, the isolation of CmCPL1, a chrysanthemum (Chrysanthemum morifolium) gene encoding this enzyme is described. Its predicted 955 residue gene product includes the FCPH catalytic domain, two double-stranded RNA binding motifs, and a nuclear localization signal. A sub-cellular localization assay confirmed that CmCPL1 was expressed in the nucleus. CmCPL1 transcription was shown to be significantly inducible by heat stress. The over-expression and knockdown of CmCPL1, respectively, increased and diminished the tolerance of chrysanthemum to heat stress, which maybe dependent on the regulation of CmCPL1 and on the expression of downstream heat stress-responsive genes.

Abstract
Many plant species are autopolyploid, a condition frequently associated with improvements in both vegetative and reproductive vigor. The possible contribution of miRNAs to this improvement was investigated by characterizing the miRNA content of a diploid and an autotetraploid form of Chrysanthemum nankingense. 162 and 161 known miRNA sequences were identified in 2x and 4x library. The length of 22 and 25 nt was predominant in diploid. However, 21 and 24 nt showed dominance in autotetraploid. It seems likely that autopolyploidization have had an immediate effect the distribution of miRNAs. In addition, the abundance of the miRNAs differed markedly between the two ploidy levels and contributed to their targets diversity. A number of target genes associated with miRNAs play important roles in growth and development. The conclusion was that some miRNAs likely make a contribution to the vigor displayed by autotetraploid C. nankingense.

Abstract
KEY MESSAGE A NAC -like gene named DlNAC1 was identified in chrysanthemum and characterized; it may be involved in regulation of response to abiotic stressors, especially in tolerance to drought and salinity. NAC transcription factors in plants play crucial roles in tolerance to abiotic stressors, and overexpression of the NAC gene in Arabidopsis has been demonstrated to lead to improved drought tolerance. Functions of the NAC genes in chrysanthemum, however, remain poorly understood. In this study, a NAC-like gene named DlNAC1 was identified in chrysanthemum (Dendranthema lavandulifolium) and characterized. Phylogenetic analysis indicated that DlNAC1 contains a typical NAC domain and belongs to the ONAC022 subgroup. According to the subcellular localization and yeast one-hybrid assay, the DlNAC1 protein is localized to nuclei and has a transcription activation ability. Moreover, quantitative real-time PCR analyses showed that DlNAC1 was induced by low-temperature, high-salinity, and drought conditions (separately), but not by abscisic acid (ABA) and heat shock. In these experiments, the downstream genes of NAC transcription factors were found to be up-regulated, including stress-responsive genes KIN1 and AMY1. To further explore the effects of DlNAC1 in response to abiotic stressors, DlNAC1 was overexpressed in tobacco, and these transgenic plants showed significantly enhanced tolerance to drought and salinity. This study suggests that in chrysanthemum, the DlNAC1 gene is involved in regulation of the response to abiotic stressors, especially in tolerance to drought and salinity.

Transcriptomic Characterization of Tambaqui (Colossoma macropomum, Cuvier, 1818) Exposed to Three Climate Change Scenarios. PLoS One 2016; 11:e0152366.

Abstract
Climate change substantially affects biodiversity around the world, especially in the Amazon region, which is home to a significant portion of the world’s biodiversity. Freshwater fishes are susceptible to increases in water temperature and variations in the concentrations of dissolved gases, especially oxygen and carbon dioxide. It is important to understand the mechanisms underlying the physiological and biochemical abilities of fishes to survive such environmental changes. In the present study, we applied RNA-Seq and de novo transcriptome sequencing to evaluate transcriptome alterations in tambaqui when exposed to five or fifteen days of the B1, A1B and A2 climate scenarios foreseen by the IPCC. The generated ESTs were assembled into 54,206 contigs. Gene ontology analysis and the STRING tool were then used to identify candidate protein domains, genes and gene families potentially responsible for the adaptation of tambaqui to climate changes. After sequencing eight RNA-Seq libraries, 32,512 genes were identified and mapped using the Danio rerio genome as a reference. In total, 236 and 209 genes were differentially expressed at five and fifteen days, respectively, including chaperones, energetic metabolism-related genes, translation initiation factors and ribosomal genes. Gene ontology enrichment analysis revealed that mitochondrion, protein binding, protein metabolic process, metabolic processes, gene expression, structural constituent of ribosome and translation were the most represented terms. In addition, 1,202 simple sequence repeats were detected, 88 of which qualified for primer design. These results show that cellular response to climate change in tambaqui is complex, involving many genes, and it may be controlled by different cues and transcription/translation regulation mechanisms. The data generated from this study provide a valuable resource for further studies on the molecular mechanisms involved in the adaptation of tambaqui and other closely related teleost species to climate change.
