Comparing Mitochondrial, Chloroplast, and Prokaryotic Genomes02:16

Comparing Mitochondrial, Chloroplast, and Prokaryotic Genomes

15.1K
The present-day mitochondrial and chloroplast genomes have retained some of the characteristics of their ancestral prokaryotes and also have acquired new attributes during their evolution within eukaryotic cells. Like prokaryotic genomes, mitochondrial and chloroplast genomes neither bind with histone-like proteins nor show complex packaging into chromosome-like structures, as observed in eukaryotes. Unlike mitotic cell divisions observed in eukaryotic cells, mitochondria and chloroplasts...

Genomics

39.8K
Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Genome Size and the Evolution of New Genes

9.0K
While every living organism has a genome of some kind (be it RNA, or DNA), there is considerable variation in the sizes of these blueprints. One major factor that impacts genome size is whether the organism is prokaryotic or eukaryotic. In prokaryotes, the genome contains little to no non-coding sequence, such that genes are tightly clustered in groups or operons sequentially along the chromosome. Conversely, the genes in eukaryotes are punctuated by long stretches of non-coding sequence.

Keystone Species01:39

Keystone Species

24.2K
Measures of species biodiversity, such as richness (i.e., the number of species present) and evenness (i.e., their relative abundance), describe an ecological community’s structure. Many factors affect community structure, including abiotic factors (e.g., sunlight and nutrients), disturbances (e.g., fire or flood), species interactions (e.g., predation or competition), and chance events (e.g., foreign species invasion). Certain species—such as keystone species—also play a...

Formation of Species01:31

Formation of Species

44.7K
Speciation describes the formation of one or more new species from one or sometimes multiple original species. The resulting species are discrete from the parent species, and barriers to reproduction will typically exist. There are two primary mechanisms, speciation with and without geographic isolation—allopatric and sympatric speciation, respectively.

Area of Science:

  • Genomics and Bioinformatics
  • Parasitology
  • Molecular Biology

Background:

  • Malaria, a tropical disease caused by Plasmodium parasites, affects millions globally.
  • A significant portion of Plasmodium falciparum genes remain uncharacterized, hindering functional understanding.
  • Existing genomic data requires sophisticated tools for functional gene prediction.

Purpose of the Study:

  • To develop a comprehensive database (malaria.tools) for analyzing Plasmodium gene function.
  • To enable cross-species comparison of gene expression and co-expression networks.
  • To facilitate the identification of genes related to parasite pathogenicity and life stages.

Main Methods:

  • Construction of gene co-expression networks using transcriptomic data from Plasmodium falciparum and P. berghei.
  • Integration of genomic data from six Plasmodium species and two Apicomplexa species.
  • Development of bioinformatics tools within malaria.tools for network analysis and gene function prediction.

Main Results:

  • The malaria.tools database integrates genomic and transcriptomic data for multiple species.
  • Tools are available for identifying co-expressed gene neighborhoods, clusters, and life stage-specific expression.
  • The platform successfully demonstrates the identification of genes relevant to pathogenicity and parasite life stages.

Conclusions:

  • malaria.tools provides valuable resources for functional genomics in Plasmodium research.
  • The database facilitates cross-species comparative analysis to uncover conserved and unique gene functions.
