Examining De Novo Transcriptome Assemblies via a Quality Assessment Pipeline
Summary
Evaluating de novo transcriptome assembly quality is crucial for non-model organisms. This study introduces a hybrid approach combining statistical and biological metrics for robust assessment, exemplified by the Pacific Whiteleg Shrimp.
Area of Science:
- Genomics
- Bioinformatics
- Marine Biology
Background:
- De novo transcriptome assembly is vital for studying organisms without reference genomes.
- Assessing the quality of these assemblies is challenging.
- Pacific Whiteleg Shrimp (Litopenaeus vannamei) lacks a robust genomic reference.
Purpose of the Study:
- To develop and validate a comprehensive workflow for evaluating de novo transcriptome assembly quality.
- To provide novel transcriptome assemblies and functional annotations for Litopenaeus vannamei.
- To highlight the limitations of relying solely on assembler statistics for quality assessment.
Main Methods:
- Composed a workflow integrating multiple quality check measurements.
- Applied statistical quality checks and biological-based evaluations.
- Generated new transcriptome assemblies and functional annotations for Litopenaeus vannamei.
Main Results:
- Demonstrated that purely statistical metrics can be misleading for assembly quality evaluation.
- Presented improved gene annotations for Litopenaeus vannamei.
- Showcased the utility of a hybrid assessment approach.
Conclusions:
- A hybrid approach combining statistical and biological evaluations provides a more accurate assessment of transcriptome assembly quality.
- The developed workflow and new annotations offer valuable resources for Litopenaeus vannamei research.
- This methodology can be applied to improve transcriptome assembly quality assessment in other non-model organisms.

16.9K
Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types. Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.

2.9K
Quality control is one of the three cyclical quality assurance activities that help keep a system under statistical control. Typical quality control activities include creating quality control charts, conducting proficiency testing, and documenting and archiving results.
Quality control helps track data, visualize trends, and identify variations, making it easier to detect deviations that may affect the accuracy of an analysis. One way to do this is by generating a quality control chart, which...

01:19Quality Assurance
2.5K
Quality assurance is the overarching term used to describe the activities employed to ensure the proper performance of a system. These activities can be classified into three categories: quality control, quality assessment, and internal corrective measures. Typically, these activities work cyclically: quality control is performed before and during the analysis, while quality assessment occurs during and after the investigation. Internal corrective measures are implemented based on the findings...

01:19Quality of Water

In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...

3.2K
Pulse amplitude is a crucial indicator of cardiac health because it provides valuable insights into the strength of left ventricular contractions and the overall uniformity of blood circulation within the vasculature. The strength of the pulse is directly related to the force with which the heart contracts and the volume of blood being pumped.
A weak or absent pulse may indicate reduced cardiac output or poor left ventricular contraction, which can be signs of cardiovascular dysfunction or...

When the quality of water for concrete preparation is uncertain, its impact on the setting time of cement and compressive strength of mortar is assessed by comparison with de-ionized or distilled water benchmarks. American Society for Testing and Materials (ASTM) C1602 requires the setting times to be within 90 minutes of the control, British Standard (BS) 3146:1980 allows a 30-minute variance in the initial setting, while British Standards European Norm (BS EN) 1008 specifies initial setting...
