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:Anther development is a complex process, and the study of its molecular mechanism has an important impact on plant breeding. This study aims to identify microRNA (miRNA), mRNA, long non-coding RNA (lncRNA), and circular RNA (circRNA) related to anther development of Chinese cabbage, so as to construct competitive endogenous RNA (ceRNA) regulatory networks and provide valuable knowledge for the exploration of pollen development mechanism of Chinese cabbage. A total of 9055 mRNA, 585 miRNA, 1344 lncRNA, and 165 circRNA were identified as differentially expressed in the anther of Chinese cabbage compared with Mix (roots, stems and leaves) by whole-transcriptome sequencing. The anther-related ceRNA-miRNA-target gene regulatory network through miRNA targeting relationships was constructed and 450 pairs of ceRNA relationships, including 97 DEmiRNA-DEmRNA, 281 DEmiRNA-DElncRNA, and 23 DEmiRNA-DEcircRNA interactions were obtained in Chinese cabbage. The genes in the ceRNA network were enriched in the pathways including starch and sucrose metabolism, carbon metabolism, pyruvate metabolism and carbon fixation in photosynthetic organisms, plant hormone signal transduction, and RNA degradation. This study identified some important genes and their interaction lncRNAs, circRNAs, and miRNAs involved in microsporogenesis (BraA06g035480.3C), tapetum and callose layer development (BraA09g009280.3C, BraA04g028920.3C, and BraA10g022680.3C etc), pollen wall formation (BraA06g000980.3C, BraA02g023130.3C, and BraA10g029650.3C etc), and anther dehiscence (BraA10g027200.3C, BraA04g023740.3C, and BraA04g030860.3C etc). Additionally, we analyzed the promoter activity of six anther predominant expression genes, and the results showed that they were all expressed specifically in the anther of Chinese cabbage. This study lay the foundation for further research on the molecular mechanism of anther growth and development.

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.

Project description:PURPOSE:To 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. Transcriptome analysis indicated that BraA09g066480.3C was expressed in ‘FT’ but not in ‘CX001’.The work presented herein demonstrated that BraA09g066480.3C was the causal gene for wax-less flowering Chinese cabbage ‘CX001’
