Summary
Genomic research on parasitic flatworms is advancing, particularly for Schistosoma species. Transcriptome analysis reveals new genes and molecular mechanisms, identifying potential drug and vaccine targets.
Area of Science:
- Parasitology
- Genomics
- Molecular Biology
Background:
- The 'post-genomic era' has seen limited progress in understanding the genomic biology of parasitic flatworms.
- Knowledge of schistosome genomics remains particularly scarce, hindering effective disease control.
Purpose of the Study:
- To review the current state of knowledge regarding the mitochondrial and nuclear genomes of parasitic flatworms.
- To highlight recent advancements in gene discovery for Schistosoma species.
- To identify potential therapeutic targets and vaccine candidates.
Main Methods:
- Transcriptome analysis of Schistosoma mansoni and Schistosoma japonicum.
- Review of existing literature on parasitic flatworm genomes.
Main Results:
- Identification of novel genes and previously unreported genes in schistosomes.
- Elucidation of molecular mechanisms underlying host-dependent maturation, immune evasion, development, signaling, and sexual dimorphism.
- Discovery of potential vaccine candidates and drug targets.
Conclusions:
- Significant progress is being made in schistosome gene discovery.
- Sequencing complete schistosome genomes is a key future goal.
- Advancements in genomic understanding offer new avenues for therapeutic intervention against schistosomiasis.

Plants often form mutualistic relationships with soil-dwelling fungi or bacteria to enhance their roots’ nutrient uptake ability. Root-colonizing fungi (e.g., mycorrhizae) increase a plant’s root surface area, which promotes nutrient absorption. While root-colonizing, nitrogen-fixing bacteria (e.g., rhizobia) convert atmospheric nitrogen (N2) into ammonia (NH3), making nitrogen available to plants for various biological functions. For example, nitrogen is essential for the...

48.4K
The genome of most prokaryotic organisms consists of double-stranded DNA organized into one circular chromosome in a region of cytoplasm called the nucleoid. The chromosome is tightly wound, or supercoiled, for efficient storage. Prokaryotes also contain other circular pieces of DNA called plasmids. These plasmids are smaller than the chromosome and often carry genes that confer adaptive functions, such as antibiotic resistance.

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...

02:30Genomic Imprinting and Inheritance
36.9K
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.

03:21Genome 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.

02:16Comparing Mitochondrial, Chloroplast, and Prokaryotic Genomes
15.6K
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...
