Chromosome numbers and meiotic analysis in the pre-breeding of Brachiaria decumbens (Poaceae). (3/24)

A total of 44 accessions of Brachiaria decumbens were analysed for chromosome count and meiotic behaviour in order to identify potential progenitors for crosses. Among them, 15 accessions presented 2n = 18; 27 accessions, 2n = 36; and 2 accessions, 2n = 45 chromosomes. Among the diploid accessions, the rate of meiotic abnormalities was low, ranging from 0.82% to 7.93%. In the 27 tetraploid accessions, the rate of meiotic abnormalities ranged from 18.41% to 65.83%. The most common meiotic abnormalities were related to irregular chromosome segregation, but chromosome stickiness and abnormal cytokinesis were observed in low frequency. All abnormalities can compromise pollen viability by generating unbalanced gametes. Based on the chromosome number and meiotic stability, the present study indicates the apomictic tetraploid accessions that can act as male genitor to produce interspecific hybrids with B. ruziziensis or intraspecific hybrids with recently artificially tetraploidized accessions.  (+info)

Polyploidy Medical Definition.

Polyploidy is a condition where an organism has more than two sets of chromosomes, which are the thread-like structures that carry genetic information. It can occur in both plants and animals, although it is relatively rare in most species. In humans, polyploidy is extremely rare and usually occurs as a result of errors during cell division or abnormal fertilization.

In medicine, polyploidy is often used to describe certain types of cancer, such as breast cancer or colon cancer, that have extra sets of chromosomes. This can lead to the development of more aggressive and difficult-to-treat tumors.

However, not all cases of polyploidy are cancerous. Some individuals with Down syndrome, for example, have an extra copy of chromosome 21, which is a non-cancerous form of polyploidy. Additionally, some people may be born with extra copies of certain genes or chromosomal regions due to errors during embryonic development, which can lead to various health problems but are not cancerous.

Overall, the term "polyploidy" in medicine is used to describe any condition where an organism has more than two sets of chromosomes, regardless of whether it is cancerous or non-cancerous.

Polyarteritis nodosa (PAN) is a rare and potentially life-threatening autoimmune disorder that affects the blood vessels, particularly the arteries. It is characterized by inflammation of the walls of multiple arteries, which can lead to damage to the surrounding tissues and organs.

The symptoms of PAN can vary depending on the location and severity of the inflammation, but may include:

* Fever
* Headache
* Joint pain and swelling
* Skin rash or lesions
* Abdominal pain
* Weight loss
* Fatigue
* Numbness or weakness in the limbs

The exact cause of PAN is not known, but it is believed to be an autoimmune disorder, meaning that the body's immune system mistakenly attacks healthy tissues. It can occur at any age, but is more common in adults between the ages of 40 and 60.

There is no cure for PAN, but treatment options include:

* Corticosteroids to reduce inflammation
* Immunosuppressive drugs to suppress the immune system
* Plasmapheresis to remove harmful antibodies from the blood
* Biologics to target specific proteins involved in the disease process

The prognosis for PAN varies depending on the severity and location of the inflammation, as well as the promptness and effectiveness of treatment. In general, the condition can be challenging to diagnose and treat, and the long-term outcome is often uncertain.

Asexual1
  • Apomixis maybe defined (Winkler, 1908, 1934) as the substitution for sexual reproduction (amphimixis) of an asexual process which does not involve any nuclear fusion. (plantlet.org)
Seeds2
  • Some hybrids do reproduce true to type via nucellar seeds in a process called apomixis . (wikipedia.org)
  • A rare form of apomixis in which only pollen (i.e. male gamete) is required to produce viable seeds. (nih.gov)
Genetically2
  • In all cases of apomixis, through the avoidance of meiosis and fertilisation, the offspring is genetically identical to that of the mother plant. (europa.eu)
  • Apomixis allows the establishment of genetically stable seed propagating clones of crops, which can perpetuate themselves across countless sporophytic generations . (bvsalud.org)
Crops2
  • Apomixis is widespread in plants, but not among crops. (europa.eu)
  • The project will provide the tools and technology necessary to harness individual elements of apomixis and to perform first functional tests in both model systems and crops. (europa.eu)
Angiosperms1
  • Nygren, A. 1967: Apomixis in the angiosperms. (ufz.de)
Sexual reproduction1
  • Because apomixis occurs more frequently than sexual reproduction, most heritability estimates should fall closer to the midparent value, resulting in lower heritability. (ashs.org)
Plant1
  • Genetic mechanism and molecular basis of apomixis in plant]. (bvsalud.org)
High1
  • This indicates a high probability of their ability to seed reproduction by apomixis. (sgu.ru)
