Project description:We conducted genome-wide transcriptome analysis using the inbred Chinese cabbage line, ‘4004’, which displayed early flowering in response to vernalization. A total of 1,677 differentially-expressed genes (DEGs) were identified with and without vernalization. Transcriptome analysis identified 223 homologs of Arabidopsis Ft genes in Chinese cabbage, and 50 of these genes responded to vernalization. RT-qPCR analysis of major Ft genes showed that the majority of flowering enhancers were up-regulated in response to vernalization, whereas most flowering repressors were down-regulated in response to vernalization. Among the major Ft genes, the expression of BrCOL1-2, BrFT1/2, BrSOC1/2/3, BrFLC1/2/3/5, and BrMAF was strongly affected by vernalization.

Project description:We report the application of high-throughput RNA sequencing for comparing the expression levels of the coding and long noncoding RNAs (lncRNAs) in leaf samples from a glossy mutant nwgl and its wild-type (WT) in cabbage. By obtaining over 163.35 Gb cleaned data generated from six libraries (on average, more than 26.48 Gb clean data for each sample replicate), we identified 1247 differential expressed genes (DEGs) and 148 differential expressed lncRNAs in nwgl leaves relative to WT. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis revealed that the DEGs and cis-regulated target genes for differential expressed lncRNAs were significantly enriched in wax and lipid biosynthetic and/or metabolic processes. Our results provide the novel foundation to explore the complex molecular basis of cuticular wax biosynthesis.

Project description:The transition from vegetative growth to reproductive growth involves many pathways. Vernalization is crucial to the formation of floral organs, the regulation of flowering time and plant breeding. The purpose of this study was to identify the mRNA, microRNA (miRNA), long non-coding RNA (lncRNA), and circular RNA (circRNA) related to vernalization of Chinese cabbage, and to construct a competitive endogenous RNA (ceRNA) network, so as to provide valuable information for exploring the molecular mechanism of vernalization of Chinese cabbage. Results: The results of whole-transcriptome sequencing showed that 2702 mRNAs, 151 lncRNAs, 16 circRNA, and 233 miRNAs were differentially expressed in vernalized (‘Ver’) and non-vernalized (‘Nor’) seeds of Chinese cabbage. Some transcription factors and regulatory proteins that play important roles in vernalization pathway have been identified, such as the transcription factors of WRKY, MYB, NAC, bHLH, and MADS-box, zinc finger protein CONSTANS like gene and B3 domain protein. We constructed vernalization-related ceRNA-miRNA-target gene network and obtained 199 pairs of ceRNA relationships, including 108 DEmiRNA-DEmRNA, 67 DEmiRNA-DElncRNA, and 12 DEmiRNA-DEcircRNA interactions in Chinese cabbage. Meanwhile, several important vernalization-related genes and their interacting lncRNAs, circRNAs, and miRNAs were identified, which were involved in the regulation of flowering time, floral organ formation, bolting and flowering. Conclusions: The candidate differentially expressed mRNA, miRNA, lncRNA and circRNA for vernalization of Chinese cabbage were identified by the whole-transcriptome sequencing, and the ceRNA network was constructed. This study laid a foundation for further study on the molecular mechanism of vernalization in Chinese cabbage.

Project description:BackgroundEpidermal wax covers the surfaces of terrestrial plants to resist biotic and abiotic stresses. Wax-less flowering Chinese cabbage (Brassica campestris L. ssp. chinesis var. utilis tsen et lee) has the charateristics of lustrous green leaves and flower stalks, which are of high commercial value.ResultsTo clarify the mechanism of the wax deficiency, the wax-less flowering Chinese cabbage doubled-haploid (DH) line 'CX001' and Chinese cabbage DH line 'FT', obtained from isolated microspore culture, were used in the experiments. Genetic analysis showed that the wax-less phenotype of 'CX001' was controlled by a recessive nuclear gene, named wlm1 (wax-less mutation 1), which was fine-mapped on chromosome A09 by bulked segregant analysis sequencing (BSA-seq) of B.rapa genome V3.0. There was only one gene (BraA09g066480.3C) present in the mapping region. The homologous gene in Arabidopsis thaliana is AT1G02205 (CER1) that encodes an aldehyde decarboxylase in the epidermal wax metabolism pathway. Semi-quantitative reverse transcription PCR and transcriptome analysis indicated that BraA09g066480.3C was expressed in 'FT' but not in 'CX001'. BraA09g066480.3C was lost in the CXA genome to which 'CX001' belonged.ConclusionThe work presented herein demonstrated that BraA09g066480.3C was the causal gene for wax-less flowering Chinese cabbage 'CX001'. This study will lay a foundation for further research on the molecular mechanism of epidermal wax synthesis in flowering Chinese cabbage.

Project description:The leaf of Chinese cabbage is the major place of photosynthesis, the mutation of leaf may directly affect the rate of plant growth and development and the formation of leafy head, and ultimately influence the yield and quality of Chinese cabbage. We identified a developmentally retarded mutant (drm) exhibiting stable inheritance, which was derived from Chinese cabbage DH line âFTâ using a combination of isolated microspore culture and radiation treatment (60Co γ-rays). The drm exhibited slow growth and development at the seedling and heading stages, leading to the production of a tiny, leafy head, as well as chlorophyll-deficient leaves, especially in seedlings. Genetic analysis indicated that the phenotype of drm was controlled by a single recessive nuclear gene. Compared with wild-type line âFTâ, the drmâs chlorophyll content was significantly reduced and its chloroplast structure was abnormal. Moreover, the photosynthetic efficiency and chlorophyll fluorescence parameters were significantly decreased. The changes in leaf color, combined with these altered physiological characters may influence the growth and development of plant, ultimately resulting in the developmentally retarded phenotype of drm. To further understand the molecular regulatory mechanisms of phenotypic differences between âFTâ and drm, comparative transcriptome analysis were performed using RNA-Seq, a total of 338 differentially expressed genes (DEGs) were detected between âFTâ and drm. According to GO and KEGG pathway analysis, a number of DEGs which involved in the chlorophyll degradation and photosynthesis were identified, such as chlorophyllase and ribulose-1,5-bisphosphate carboxylase/oxygenase. In addition, the expression patterns of 12 DEGs, including three chlorophyll degradation- and photosynthesis-related genes and nine randomly selected genes, were confirmed by qRT-PCR. Numerous single nucleotide polymorphisms were also identified, providing a valuable resource for research and molecular marker-assistant breeding in Chinese cabbage. These results contribute to our understanding of the molecular regulatory mechanisms underlying growth and development and lay the foundation for future genetic and functional genomics studies in Chinese cabbage. The RNA from the third true leaves (day 15 to day 24 after the appearance of the third true leaves) of a developmentally retarded mutant (drm) and its wild type âFTâ in Chinese cabbage were sequenced by RNA-Seq, in triplicate.
