What is Allotetraploid genome?
1. a hybrid cell or individual possessing four times the chromosomes in a haploid organism. adjective. 2. possessing four times the chromosomes in a haploid organism.
How many genes does Oryza sativa have?
Oryza sativa has a haploid chromosome number of 12, containing 370 Mb with about 36,000 protein-coding genes. Rice was an obvious choice for the first whole genome sequencing of a cereal crop.
How many different genomes are there in rice?
The genus Oryza has 22 wild rice species with nine genomes (AA, BB, CC, BBCC, CCDD, EE, FF, GG and HHJJ). This is in addition to the two widely cultivated species Oryza sativa (AA genome) and O.
What is the genome size of indica rice type?
Table 1
| Rice | Genome type | Genome size (Mb) |
|---|---|---|
| O. sativa L. ssp. indica (cv. Shuhui498) | AA | 391.0 |
| O. sativa L. ssp. indica (cv. Minghui 63) | AA | 398.8 |
| AA | 387.4 | |
| O. sativa L. ssp. indica (cv. Zhenshan 97) | AA | 386.5 |
What is an example of Allotetraploid?
Both bread wheat and Triticale are examples of an allopolyploids with six chromosome sets. Cotton, peanut, or quinoa are allotetraploids with multiple origins.
What is the common name of Oryza sativa?
rice
rice, Oryza sativa Cyperales: Poaceae.
What is map based sequencing?
Mapping involves (1) dividing the chromosomes into smaller fragments that can be propagated and characterized and (2) ordering (mapping) them to correspond to their respective locations on the chromosomes. After mapping is completed, the next step is to determine the base sequence of each of the ordered DNA fragments.
Why does rice have more genes?
Whereas estimates of the number of genes in the human genome lie between 30,000 and 40,000, indica rice contains between 45,000 and 56,000 genes, and japonica rice could have as many as 63,000 genes. The reason for the multitude, scientists suggest, is because plants rely on gene duplication for protein diversity.
What is banana genome?
The acuminata genome, designated by the letter A in the nomenclature system used to classify edible bananas, is the genome of Musa acuminata, a species of wild bananas that has been involved in the domestication of the vast majority of edible bananas. It is also the first genome to be sequenced in the genus Musa.
Why is nipponbare important?
The rice genome sequence of Nipponbare has been pivotal in the development of a system for discovering the biological functions of approximately 32,000 genes identified in rice.
What is the main difference between Autopolyploid and allopolyploid?
The main difference between autopolyploidy and allopolyploidy is that autopolyploidy is the containment of multiple sets of chromosomes that are derived from the same species whereas allopolyploidy is the containment of multiple sets of chromosomes that are derived from different species.
What is the difference between Alloploidy and Autoploidy?
Autopolyploid organisms have more than two sets of chromosomes that are from the same species, such as the piggyback plant. Allopolyploid organisms have more than two sets of chromosomes that are from different species, such as the wheat plant, Triticum aestivum or the cotton genus Gossypium.
What is meant by allopolyploidy?
Definition of allopolyploid : a polyploid individual or strain having a chromosome set composed of two or more chromosome sets derived more or less complete from different species.
What is the family of Oryza sativa?
GrassesRice / Family
What is the meaning of L in Oryza sativa L?
The genus Oryza contains 23 species, two of which are cultivated; O. sativa L. (sativa means cultivated in botanical Latin) and O. glaberrima (African rice, grown in parts of West Africa).
What is the difference between genetic map and physical map?
What is the difference between a genetic and a physical map? Genetic maps depict relative positions of loci based on the degree of recombination. This approach studies the inheritance/assortment of traits by genetic analysis. Physical maps show the actual (physical) distance between loci (in nucleotides).
