Rice (Oryza sativa) has a small genome of about 0.4 Gb (size mentioned is that of the haploid genome in each of the cases); it has the simplest of the monocotyledonous genomes. The chromosome number is 2n = 24, n = 12 chromosomes.
It can be argued that the sex chromosomes are the most important pair of chromosomes given their role in determining gender and, therefore, allowing for reproduction and procreation. Considered together, sex chromosome aneuploidies are the most common chromosome abnormalities seen in live-born infants,...
The invention discloses rice thread minute chromosome and its gaining method. It is made up of centromere, telomere, and one in three short arm of the rice number 11 chromosome. One rush of chain of the telomere DNA extends from 5'to 3', grows 7-10.5kb by connecting 1000-1500 repeating...

using a dissection microscope (ZEISS, Dublin, CA). The number of ASC was calculated using the mean number of spots from triplicate wells. Mice demonstrating an average of less than 20 spots in the 5 × 106dilution were considered non-responders and not included in subsequent analyses. ...
(variable number tandem repeats);Aluinsertions may be polymorphic; chromosome deletions and rearrangements are polymorphic in humans; gene structure and copy number may be polymorphic. (The latter are copy number variants, which are common.) The extent of polymorphic variation in humans is exceptional...
Thus, the average gene density of chromo- some 1 is about one gene per 6.4 kb. If this distribution is assumed to be similar throughout the whole genome, then the total number of genes in the rice genome (400 Mb) is roughly 62,500. This number is 2.5 times larger than the gene ...
number of nucleoli; (2) decrease of growth rate, mitotic index and DNA synthesis rate; (3) loss of the ability to growth in soft agar medium, and non-tumorigenic under heterotransplantation to nude mice; (4) reduction of chromosome number mainly of rat derivative and decrease in chromosomal...
A quantitative pachytene chromosome map of rice (Oryza sativa L.) was developed using imaging methods. The map depicts not only distribution patterns of chromomeres specific to pachytene chromosomes, but also the higher order information of chromosomal structures, such as heterochromatin (condensed reg...
Survey of Chromosome Numbers in Rubus (Rosaceae: Rosoideae) A literature survey was made of chromosome number counts for Rubus species. Numbers are presented for 387 species, representing about 40% of the total numb... MM Thompson - 《Annals of the Missouri Botanical Garden》 被引量: 131发表...
