Transcriptome profiling for seed abortion in Ponkan (Citrus reticulata)

Project description:Seed developmental arrest is one of the early phenotypes of seed abortion. However, the molecular mechanism underlying seed developmental arrest of citrus is still unclear. In this study, laser capture microdissection (LCM) was used to accurately divide the seeds of seedless Ponkan ‘Huagan No.4’ (Citrus reticulata) (HG) and seeded Ponkan ‘Egan No.1’ (Citrus reticulata) (EG) into nucellus and integument/seed coat tissues. The captured tissues were used for subsequent RNA-seq. Moreover, single-molecule real-time (SMRT) sequencing was used to generate full-length transcripts of EG, which were used as reference transcripts for RNA-seq. These data can be utilized to analyse the causes of citrus seedlessness formation and the molecular regulatory network in the process of seed abortion.

Laser capture microdissection-based spatiotemporal transcriptomes uncover regulatory networks during seed abortion in Ponkan (Citrus reticulate)

Project description:Seed abortion is one of the important reasons for the formation of seedless characters in citrus. However, the molecular mechanism of seed abortion in citrus is still unclear. We identified several genes that may play an important role in seed abortion of 'Huagan 4', such as CrWRKY74. The downstream regulatory network of CrWRKY74 was identified based on DAP seq analysis to gain insight into the molecular mechanism related to seed abortion.

Transcriptome analysis of Citrus reticulata ovule early development based on laser capture microdissection

Project description:Ovule developmental arrest is one of the early phenotypes of seed abortion. However, the molecular mechanism underlying ovule developmental arrest of citrus is still unclear. In this study, laser capture microdissection (LCM) was used to accurately divide the ovules of seedless Ponkan ‘Huagan NO.4’ (Citrus reticulata) (MT) and seeded Ponkan ‘Egan NO.1’ (Citrus reticulata) (WT) into nucellus and integument tissues. The captured tissues were used for subsequent RNA-seq. Moreover, single-molecule real-time (SMRT) sequencing was used to generate full-length transcripts of WT, which were used as reference transcripts for RNA-seq. These data can be utilized to analyse the causes of citrus seedlessness formation and the molecular regulatory network in the process of ovule abortion.

Mouse placenta in spontaneous abortion

Project description:Genetic profiles of mouse placenta were examined especially at the implantation sites of causing spontaneous abortion at day 14.5 of pregnancy. There is a number of the suffered patients from the recurrent spontaneous abortion by unknown causes. It is an important process to understand genetic profiles in the abortion placentas for the investigation of specific causes to induce rejection of normal embryos from the maternal attack. Our study was carried out on the laboratory mice targeted spontaneous abortion to approximate human disease models.

Development of a Laser Microdissection-Coupled Quantitative Shotgun Lipidomic Method to Uncover Spatial Heterogeneity.

Project description:Lipid metabolic disturbances are associated with several diseases, such as type 2 diabetes or malignancy. In the last two decades, high-performance mass spectrometry-based lipidomics has emerged as a valuable tool in various fields of biology. However, the evaluation of macroscopic tissue homogenates leaves often undiscovered the differences arising from micron-scale heterogeneity. Therefore, in this work, we developed a novel laser microdissection-coupled shotgun lipidomic platform, which combines quantitative and broad-range lipidome analysis with reasonable spatial resolution. The multistep approach involves the preparation of successive cryosections from tissue samples, cross-referencing of native and stained images, laser microdissection of regions of interest, in situ lipid extraction, and quantitative shotgun lipidomics. We used mouse liver and kidney as well as a 2D cell culture model to validate the novel workflow in terms of extraction efficiency, reproducibility, and linearity of quantification. We established that the limit of dissectible sample area corresponds to about ten cells while maintaining good lipidome coverage. We demonstrate the performance of the method in recognizing tissue heterogeneity on the example of a mouse hippocampus. By providing topological mapping of lipid metabolism, the novel platform might help to uncover region-specific lipidomic alterations in complex samples, including tumors.

Expression data from postharvest Ponkan (Citrus reticulata Blanco) fruit under cold storage

Project description:Low temperature storage of citrus fruits are susceptible to chilling disorder symptoms that impact fruit quality. Understanding the molecular frame underlying the cold storage process will provide a basic guidance for practical control. We used Affymetrix Citrus GeneChip to examine the transcriptional changes in cold-stored Citrus reticulata Blanco cv. ‘Ponkan’ pulp tissue for three successive months.
