RNA-seq

RNA-seq

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while...

Ribosome Profiling

Ribosome Profiling

Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
The technique...

Genomic DNA in Eukaryotes

Genomic DNA in Eukaryotes

Eukaryotes have large genomes compared to prokaryotes. To fit their genomes into a cell, eukaryotic DNA is packaged extraordinarily tightly inside the nucleus. To achieve this, DNA is tightly wound around proteins called histones, which are packaged into nucleosomes that are joined by linker DNA and coil into chromatin fibers. Additional fibrous proteins further compact the chromatin, which is recognizable as chromosomes during certain phases of cell division.

To generate comprehensive gene sets for sugar beet and spinach.

Main Methods:

Utilized PacBio SMRT cDNA reads for gene model prediction and validation.
Developed an automated process for gene model validation.
Optimized training and prediction settings for gene prediction.
Incorporated mRNA-seq data with noise reduction from Illumina reads to assist gene prediction.

Main Results:

Achieved 98% of full-insert SMRT reads spanning complete open reading frames.
Demonstrated increased gene prediction sensitivity and precision through optimized settings and noise reduction.
Generated an improved genome-wide gene set for sugar beet (Beta vulgaris).
Produced the first genome-wide gene set for spinach (Spinacia oleracea).

Conclusions:

The developed workflow provides a valuable resource for obtaining comprehensive gene sets for newly sequenced eukaryotic genomes.
The method enhances the accuracy and efficiency of gene model prediction and validation.
This work contributes significantly to the genomic resources for sugar beet and spinach.
