What is the genome size of Cyanidioschyzon merolae?

16 Mb
The nuclear genome is compact (16 Mb), comprising 20 chromosomes with 5,331 predicted genes. Interestingly, only 26 of the predicted genes have introns. The genome was assembled by the Cyanidioschyzon merolae Genome Project.

What does Cyanidioschyzon Merolae do?

merolae makes it the perfect organism for studying mechanisms of eukaryotic cell and organelle division. Synchronization of the division of organelles in cultured cells can be very simple and usually involves the use of light and dark cycles.

How many chromosomes does red algae have?

20 chromosomes
Here we report the 16,520,305-base-pair sequence of the 20 chromosomes of the unicellular red alga Cyanidioschyzon merolae 10D as the first complete algal genome. We identified 5,331 genes in total, of which at least 86.3% were expressed.

Does red algae have DNA?

Early diverging red algal lineages are characterized by relatively small 2C DNA contents while a wide range of 2C values is found within the derived Florideophyceae. Current data do support polyploidy and aneuploidy as pervasive features of red algal genome evolution.

How many chromosomes are in green algae?

Is red algae closely related to plants?

Present-day green and red algae appear to be close relatives of other plants. Algae play a significant role in aquatic ecology. Microscopic algae, called phytoplankton, that live suspended in water form the food base for most marine food chains.

Do algae have DNA?

The algal cell. The nucleus contains most of the genetic material, or deoxyribonucleic acid (DNA), of the cell. In most algae, the molecules of DNA exist as linear strands that are condensed into obvious chromosomes only at the time of nuclear division (mitosis).

Which algae has smallest chromosome?

The Ostreococcus genus exhibits the smallest genomes among sequenced green algae and as in other unicellular green algae, each chromosome is present in one copy.

How many chromosomes do fruit flies have?

eight chromosomes
These body (somatic) cells undergo mitosis. Fruit fly somatic cells have eight chromosomes.

What is red algae most closely related to?

According to recent phylogenetic studies of evolutionary relationships, some algae (the red algae and most green algae) are indeed most closely related to the land plants, but other algae are related to certain protist groups.

Are algae Autotrophs or Heterotrophs?

Algae, along with plants and some bacteria and fungi, are autotrophs. Autotrophs are the producers in the food chain, meaning they create their own nutrients and energy.

How do algae contain genetic information?

When was the complete sequence of the Merola genome released?

C. merolaegenome sequence released (Apr 8 2004) We have a pleasure to announce the release of the complete sequence of C. merolaenuclear genome. The first analysis of C. merolaegenome can be found in the paper Matsuzaki, M. et al.Nature428, 653-657 (2004). Reference: Matsuzaki, M. et al.Nature428, 653-657 (2004)

Why is there no myosin gene in c.merolae?

The lack of a myosin gene, in addition to the unexpressed actin gene, suggests a simpler system of cytokinesis. These results indicate that the C. merolae genome provides a model system with a simple gene composition for studying the origin, evolution and fundamental mechanisms of eukaryotic cells.

Is the C merolaegenome genome 100% complete?

100% genome sequence is published (10 Jul 2007) After 3 years effort, we have achieved literally 100% completeness of C. merolaegenome sequences. The detail is reported in the paper Nozaki, H. et al.BMC Biology5, 28 (2007). ***PLEASE NOTE that the database is still based on old incomplete sequences***.

How does red algae reproduce?

Red algae reproduce sexually as well as asexually. Asexual reproduction can occur through the production of spores and by vegetative means (fragmentation, cell division or propagules production).

Where does red algae come from?

Habitat and Distribution. Red algae are found around the world, from polar waters to the tropics, and are commonly found in tide pools and in coral reefs.

How many chromosomes do crabs have?

Animal chromosome numbers range from 254 in hermit crabs to 2 in a species of roundworm. The fern called Ophioglossum reticulatum has 1260 chromosomes! Humans have 46, chimpanzees have 48, and yes, potatoes also have 48.

How does an algae reproduce?

Algae regenerate by sexual reproduction, involving male and female gametes (sex cells), by asexual reproduction, or by both ways. Many small algae reproduce asexually by ordinary cell division or by fragmentation, whereas larger algae reproduce by spores.

How do fungi and algae reproduce?

Asexual Reproduction Fungi reproduce asexually through three methods: Spores: Spores are formed by the fungi and released to create new fungi. Spores are haploid reproductive cells found in some bacteria, plants, algae, fungi, and protozoa. Theoretically, spores can reproduce asexually to produce countless offspring.

What causes red algae in a pond?

The most common cause of reddish ponds is the leeching of organic colour, called tannins, into surrounding water from decomposing matter. Although any type of debris can cause tannin, if your pond is looking particularly red in color, it is likely being produced by specific debris, such as maple leaves.

What kind of environment does Cyanidioschyzon merolae live in?

It possesses a complex life cycle with distinct vegetative and sexual stages for which specialized functions may have evolved. In contrast, Cyanidioschyzon is an asexual alga that lives in acidic sulfur- and metal-rich (Fe, Ni, etc.) hot springs ( Gross, 2000; Ciniglia et al., 2004 ).

Which is more complex Cyanidioschyzon or Chlamydomonas?

Chlamydomonas appears to be more complex than Cyanidioschyzon with respect to the size of the different transporter families ( Table 10.1 ). Chlamydomonas is a motile organism that needs to adapt to a fluctuating environment in water and soils.

When does the inner PD ring assemble in c.merolae?

In C. merolae, the inner PD ring assembles first, followed by near simultaneous assembly of the middle and outer PD rings. Once all three rings are in place, chloroplast constriction commences.

What kind of life cycle does Chlamydomonas have?

Chlamydomonas is a motile organism that needs to adapt to a fluctuating environment in water and soils. It possesses a complex life cycle with distinct vegetative and sexual stages for which specialized functions may have evolved.
