Project description:Background: The growth and development of leaf and petiole have an important influence on the photosynthesis of plants. The research on molecular mechanism of leaf and petiole development is of great significance, whether it is to improve plant photosynthetic efficiency, cultivate varieties with high photosynthetic efficiency, or improve the yield of crops using leaves as food organs. In this study, we aimed to identify the mRNAs, long non-coding RNAs (lncRNAs), microRNAs (miRNAs), and circular RNAs (circRNAs) related to leaf and petiole development in Chinese cabbage (Brassica campestris L. ssp. pekinensis). These data were then used to construct competitive endogenous RNA (ceRNA) networks, which can provide valuable information for better understanding the mechanism of leaf and petiole development. Results: In this study, the leaf and petiole of the baby Chinese cabbage inbred line ‘PHL’ were used as research materials for whole-transcriptome sequencing. A total of 10646 differentially expressed (DE) mRNAs, 303 DE lncRNAs, 7 DE circRNAs, and 195 DE miRNAs were identified between the leaf and petiole. Some transcription factors or proteins that play important roles in leaf and petiole development were identified, such as xyloglucan endotransglucosylase/hydrolase (XTH) protein, expansion protein, TCP15 transcription factor, bHLH transcription factor, LOB domain protein, cellulose synthase (CESA), MOR1-like protein, and plant hormone biosynthesis related genes. Additionally, we constructed a leaf and petiole development-related ceRNA regulatory network, and obtained 85 pairs of ceRNA relationships, including 71 DEmiRNA-DEmRNA, 12 DEmiRNA-DElncRNA and 2 DEmiRNA-DEcircRNA. Three LSH genes (BrLSH1, BrLSH2 and BrLSH3) with significant differential expression between leaf and petiole of baby Chinese cabbage were screened from transcriptome data for subcellular localization analysis and overexpression transgenic verification. The results showed that BrLSH1, BrLSH2 and BrLSH3 were nucleoprotein and BrLSH2 has an obvious inhibitory effect on the growth and development of Arabidopsis thaliana. Conclusions: Our results revealed the potential mRNAs and non-coding RNAs (ncRNAs) involved in leaf and petiole development, which laid a foundation for further research on the molecular mechanism of leaf and petiole development in Chinese cabbage.

Project description:BackgroundThe growth and development of leaves and petioles have a significant effect on photosynthesis. Understanding the molecular mechanisms underlying leaf and petiole development is necessary for improving photosynthetic efficiency, cultivating varieties with high photosynthetic efficiency, and improving the yield of crops of which the leaves are foodstuffs. This study aimed to identify the mRNAs, long non-coding RNAs (lncRNAs), microRNAs (miRNAs), and circular RNAs (circRNAs) related to leaf and petiole development in Chinese cabbage (Brassica campestris L. ssp. pekinensis). The data were used to construct a competitive endogenous RNA (ceRNA) network to obtain insights into the mechanisms underlying leaf and petiole development.ResultsThe leaves and petioles of the 'PHL' inbred line of Chinese cabbage were used as research materials for whole transcriptome sequencing. A total of 10,646 differentially expressed (DE) mRNAs, 303 DElncRNAs, 7 DEcircRNAs, and 195 DEmiRNAs were identified between leaves and petioles. Transcription factors and proteins that play important roles in leaf and petiole development were identified, including xyloglucan endotransglucosylase/hydrolase, expansion proteins and their precursors, transcription factors TCP15 and bHLH, lateral organ boundary domain protein, cellulose synthase, MOR1-like protein, and proteins related to plant hormone biosynthesis. A ceRNA regulatory network related to leaf and petiole development was constructed, and 85 pairs of ceRNA relationships were identified, including 71 DEmiRNA-DEmRNA, 12 DEmiRNA-DElncRNA, and 2 DEmiRNA-DEcircRNA pairs. Three LSH genes (BrLSH1, BrLSH2 and BrLSH3) with significant differential expression between leaves and petioles were screened from transcriptome data, and their functions were explored through subcellular localization analysis and transgenic overexpression verification. BrLSH1, BrLSH2 and BrLSH3 were nuclear proteins, and BrLSH2 inhibited the growth and development of Arabidopsis thaliana.ConclusionsThis study identifies mRNAs and non-coding RNAs that may be involved in the development of leaves and petioles in Chinese cabbage, and establishes a ceRNA regulatory network related to development of the leaves and petioles, providing valuable genomic resources for further research on the molecular mechanisms underlying leaf and petiole development in this crop species.

Project description:Anther development is precisely regulated by a complex gene network, which is of great significance to plant breeding. However, the molecular mechanism of anther development in Chinese cabbage is unclear. Here, we identified microRNAs (miRNAs), mRNAs, long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs) related to anther development in Chinese cabbage (Brassica campestris L. ssp. pekinensis) to construct competitive endogenous RNA (ceRNA) regulatory networks and provide valuable knowledge on anther development. Using whole-transcriptome sequencing, 9055, 585, 1344, and 165 differentially expressed mRNAs (DEmRNAs), miRNAs (DEmiRNAs), lncRNAs (DElncRNAs), and circRNAs (DEcircRNAs) were identified, respectively, in the anthers of Chinese cabbage compared with those in samples of the vegetative mass of four true leaves. An anther-related ceRNA regulatory network was constructed using miRNA targeting relationships, and 450 pairs of ceRNA relationships, including 97 DEmiRNA-DEmRNA, 281 DEmiRNA-DElncRNA, and 23 DEmiRNA-DEcircRNA interactions, were obtained. We identified important genes and their interactions with lncRNAs, circRNAs, and miRNAs involved in microsporogenesis, tapetum and callose layer development, pollen wall formation, and anther dehiscence. We analyzed the promoter activity of six predominant anther expression genes, which were expressed specifically in the anthers of Arabidopsis thaliana, indicating that they may play an important role in anther development of Chinese cabbage. This study lays the foundation for further research on the molecular mechanisms of anther growth and development in Chinese cabbage.

Project description:BackgroundThe transition from vegetative growth to reproductive growth involves various pathways. Vernalization is a crucial process for floral organ formation and regulation of flowering time that is widely utilized in plant breeding. In this study, we aimed to identify the global landscape of mRNAs, microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs) related to vernalization in Chinese cabbage. These data were then used to construct a competitive endogenous RNA (ceRNA) network that provides valuable information to better understand the vernalization response.ResultsIn this study, seeds sampled from the Chinese cabbage doubled haploid (DH) line 'FT' with or without vernalization treatment were used for whole-transcriptome sequencing. A total of 2702 differentially expressed (DE) mRNAs, 151 DE lncRNAs, 16 DE circRNAs, and 233 DE miRNAs were identified in the vernalization-treated seeds. Various transcription factors, such as WRKY, MYB, NAC, bHLH, MADS-box, zinc finger protein CONSTANS-like gene, and B3 domain protein, and regulatory proteins that play important roles in the vernalization pathway were identified. Additionally, we constructed a 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. Furthermore, several important vernalization-related genes and their interacting lncRNAs, circRNAs, and miRNAs, which are involved in the regulation of flowering time, floral organ formation, bolting, and flowering, were identified.ConclusionsOur results reveal the potential mRNA and non-coding RNAs involved in vernalization, providing a foundation for further studies on the molecular mechanisms underlying vernalization in Chinese cabbage.

Project description:Plants possess various defense strategies to counter attacks from microorganisms or herbivores. For example, plants reduce the cell-wall-macerating activity of pathogen- or insect-derived polygalacturonases (PGs) by expressing PG-inhibiting proteins (PGIPs). PGs and PGIPs belong to multi-gene families believed to have been shaped by an evolutionary arms race. The mustard leaf beetle Phaedon cochleariae expresses both active PGs and catalytically inactive PG pseudoenzymes. Previous studies demonstrated that (i) PGIPs target beetle PGs and (ii) the role of PG pseudoenzymes remains elusive, despite having been linked to the pectin degradation pathway. For further insight into the interaction between plant PGIPs and beetle PG family members, we combined affinity purification with proteomics and gene expression analyses, and identified novel inhibitors of beetle PGs from Chinese cabbage (Brassica rapa ssp. pekinensis). A beetle PG pseudoenzyme was not targeted by PGIPs, but instead interacted with PGIP-like proteins. Phylogenetic analysis revealed that PGIP-like proteins clustered apart from classical PGIPs but together with proteins, which have been involved in developmental processes. Our results indicate that PGIP-like proteins represent not only interesting novel PG inhibitor candidates in addition to classical PGIPs, but also fascinating new players in the arms race between herbivorous beetles and plant defenses.

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.
