Project description:Transcriptome analysis of circular RNAs in the fast-growing species moso bamboo
2019-01-01 | GSE104951 | GEO
Project description:Moso bamboo is a fast-growing bamboo species with high economic, social and cultural value. The method of transplanting moso bamboo seedlings for afforestation has become a more economical and effective method. The effect of light on the growth of plant seedlings is mainly reflected in the regulation of different light quality on the growth and development of seedlings, including light morphogenesis, photosynthesis and secondary metabolites. Therefore, studying the effects of specific wavelength light on the physiology and proteome of moso bamboo seedlings will play an important role in growing seedlings and seed cultivation of moso bamboo. Here, moso bamboo seeds were germinated in the dark and then were transferred to the blue and red-light conditions. After 14 days, we observed the effects of different light treatments on the growth and development of seedlings, and then compared and analyzed their proteome.

Project description:Moso bamboo is well known with its rapid growth rate. In order to shed light on the underlying mechanism of growth, we applied Gibberellin (GA) to mimic the fast development process in bamboo and found that exogenous GA can significantly increase the length of internode of moso bamboo. Subsequently, we sequenced the transcriptome by high-through sequencing and identified 5,148 different expressed genes (DEG) and find out 22 genes that take part in GA signaling pathway is significantly differently expressed, including GID1A, GID1B and GAI. From GO analysis, a group of genes related to response hormone stimulus are enriched in up-regulated DEGs and 178 GA-responded genes are involved in other plant hormone signaling pathway, of which genes MYB74 and NCED5 are belong to both two pathways. Besides, clusters of genes about photosynthesis are enriched in down-regulated DEGs. By looking into the content of chlorophyll, we find out that the concentrations of chlorophyll are obviously decreased which verify that photosynthesis do weakened after GA treatment. Through method of slicing by hand, it appears that an increased condensation of lignin after GA treatment. The results imply a functional role of GA in bamboo growth, and maybe major in cell wall formation, and photosynthesis. Differential AS alternative splicing (AS) events upons GA induce suggested that post-transcriptional regulation is involved in the GA response.

Project description:Moso bamboo (Phyllostachys edulis) is one of the fast-growing plant species and has high comprehensive utilization value. However, how Moso bamboo realize the transition from initial growth of winter shoot to fast growth of spring shoot is still unknown. Large increase of biomass in spring shoot suggests that alterations in bioenergetic processes may contribute to fast growth initiation. In this study, we successfully isolated mitochondria from winter shoots and spring shoots of Moso bamboo, and performed a total and mitochondrial transcriptomic and proteomic analysis using RNA sequencing and Label-free quantitative proteomics technology. The main objective of the study was to augment the genomic and proteomic data available for Moso bamboo, identify key genes/proteins involved in energy metabolism, and systematically understand the energy metabolism mechanism of shoots growth during the transitory stage from initial growth to rapid growth.

Project description:Transcriptome analysis of Gibberellin-response gene in the fast-growing species moso Bamboo

Project description:Gill transcriptome of fast- and slow-growing mussels reared under continuous food supply was recently analysed in order to ascertain the differential gene expression underlying interindividual differences in growth rate. The present study aims to analyse the gene expression differences between fast- and slow-growing mussels submitted to an air exposure of 8 hours a day during the rearing period. Transcriptome will be also compared with their continuously submerged counterparts in order to analyse the effect of air exposure on the gene expression of fast- and slow-growing individuals.

Project description:Brassinosteroids (BRs) are a group of plant steroid hormones that play crucial roles various of growth and developmental processes. Biological function and signal transduction pathway of BR has been well characterized in model plants like Arabidopsis and rice. However, their biological roles are still unclear in tree species, especially in an important non-timber plant moso bamboo, which has great ecological and economic value and distinguish fast-growth feature. Here we reported that reduce endogenous brassinosteroid by biosynthesis inhibitor propiconazole reduced both root and shoot growth in seedling stage. Exogenous BR application promoted shoot bract elongation and inclination of lamina joint and bract. Genome-wide transcriptome analysis were performed to identify hundreds of differential expressed genes by BR and propiconazole treatment in shoot and root parts of bamboo seedling, respectively. GO analysis revealed that BR regulates cell wall related genes, hydrogen peroxide catabolic genes and auxin related genes to promote bamboo root development and elongation. Our study identified BR response genes and provides a comprehensive resource for molecular mechanism research of bamboo growth.

Project description:Background: Food supply is a major factor influencing growth rates in animals. This has important implications for both natural and farmed fish populations, since food restriction may difficult reproduction. However, a study on the effects of food supply on the development of juvenile gonads has never been transcriptionally described in fish. Methods and Findings: This study investigated the consequences of growth on gonadal transcriptome of European sea bass in: 1) 4-month-old sexually undifferentiated fish, comparing the gonads of fish with the highest vs. the lowest growth, to explore a possible link between transcriptome and future sex, and 2) testis from 11-month-old juveniles where growth had been manipulated through changes in food supply. The four groups used were: i) sustained fast growth, ii) sustained slow growth, iii) accelerated growth, iv) decelerated growth. The transcriptome of undifferentiated gonads was not drastically affected by initial natural differences in growth. Further, changes in the expression of genes associated with protein turnover were seen, favoring catabolism in slow-growing fish and anabolism in fast-growing fish. Moreover, while fast-growing fish took energy from glucose, as deduced from the pathways affected and the analysis of protein-protein interactions examined, in slow-growing fish lipid metabolism and gluconeogenesis was favored. Interestingly, the highest transcriptomic differences were found when forcing initially fast-growing fish to decelerate their growth, while accelerating growth of initially slow-growing fish resulted in full transcriptomic convergence with sustained fast-growing fish. Conclusions: Food availability during sex differentiation shapes the juvenile testis transcriptome, as evidenced by adaptations to different energy balances. Remarkably, this occurs in absence of major histological changes in the testis. Thus, fish are able to recover transcriptionally their testes if they are provided with enough food supply during sex differentiation; however, an initial fast growth does not represent any advantage in terms of transcriptional fitness if later food becomes scarce.
