Transgenic Plants02:50

Transgenic Plants

8.2K
Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...

Constitutive and Regulated Gene Expression

685
Gene expression in prokaryotes is governed by constitutive and regulated systems, allowing cells to balance the production of essential proteins with adaptive responses to environmental changes.Constitutive Gene ExpressionConstitutive, or housekeeping, genes are continuously expressed as they encode proteins vital for fundamental cellular processes. These include enzymes for glycolysis, ribosomal components for protein synthesis, and proteins involved in DNA replication. Their constant...

Coordination of Gene Expression Processes in Bacteria

453
The DNA replication, transcription, and translation processes are intricately coupled in bacteria, allowing efficient gene expression and rapid protein synthesis. While this physical and functional coordination is advantageous, it introduces challenges that bacteria overcome through specific regulatory mechanisms.Coupling of Replication, Transcription, and TranslationThe coupling of replication, transcription, and translation is a hallmark of bacterial gene expression. As the replisome unwinds...

Area of Science:

  • Plant Science
  • Genomics
  • Bioinformatics

Background:

  • Rapeseed (Brassica napus) is a crucial global crop for oil and protein, but research is hindered by difficult access to expression data.
  • Understanding gene expression is key to improving rapeseed traits and yields.

Purpose of the Study:

  • To develop a centralized, user-friendly database for rapeseed gene expression data.
  • To facilitate research into gene function and rapeseed biology at the transcriptome level.

Main Methods:

  • RNA sequencing (RNA-Seq) of 103 tissues from rapeseed cultivar ZhongShuang11 across seven developmental stages.
  • Analysis of 70 additional rapeseed transcriptome datasets from the Sequence Read Archive (SRA) database.
  • Development of the Brassica Expression Database (BrassicaEDB) with specialized modules for expression profiles and gene sequences.

Main Results:

  • Generated expression profiles for 101,040 genes using FPKM analysis.
  • Integrated diverse expression data (FPKM, TPM, read counts) from internal and public datasets.
  • Created BrassicaEDB with modules including eFP browser, Treatment, Coexpression, Gene Feature, qPCR Primer, and BLAST.

Conclusions:

  • BrassicaEDB provides a comprehensive resource for rapeseed researchers.
  • The database enables efficient retrieval and visualization of gene expression data, supporting functional genomics and crop improvement efforts.
