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)

We have compared the transcriptomic profiles of microdissected live ovules at four developmental stages between a diploid sexual and diploid apomictic Boechera. We sequenced ,2 million SuperSAGE tags and identified (1) heterochronic tags (n = 595) that demonstrated significantly different patterns of expression between sexual and apomictic ovules across all developmental stages, (2) stage-specific tags (n = 577) that were found in a single developmental stage and differentially expressed between the sexual and apomictic ovules, and (3) sex-specific (n = 237) and apomixis-specific (n = 1106) tags that were found in all four developmental stages but in only one reproductive mode. Most heterochronic and stage-specific tags were significantly downregulated during early apomictic ovule development, and 110 were associated with reproduction. By contrast, most late stage-specific tags were upregulated in the apomictic ovules, likely the result of increased gene copy number in apomictic (hexaploid) ...
For angiosperms, apomixis means asexual reproduction by seed [1]. It is strongly associated with hybridity and polyploidy, and molecular mechanisms responsible for it remain shrouded in complexity [2-4]. Apomixis involves the reprogramming of unreduced (2n) cells of the ovule, which thereafter follow a very different developmental trajectory than had the plant been sexual. Specifically, ovules of apomictic plants produce asexual totipotent cells. These form in the nucellus, chalaza or integuments, and embryos develop from them either directly (adventitious embryony) or after 2n embryo sac (ES) formation (gametophytic apomixis). Apomictic (2n) ES usually resemble sexual ES, but embryony in them occurs parthenogenetically and often precociously. Whether in sexual plants or apomicts, embryony is the result of epigenome modifications that begin as early as floral transition [5, 6].. Gametophytic apomixis is further divided into i) apospory, where the 2n aposporous ES (AES) forms from a cell of the ...

On the slopes of the Northern Rocky Mountains, the flowering mustard plant Boechera stricta is undergoing a quiet transformation - that is, evolving into a fitter species better adapted to its local environment. HudsonAlpha faculty investigator Jeremy Schmutz was part of a team led by Thomas Mitchell-Olds of Duke University who analyzed the mechanisms by which Boechera stricta living in a hybrid zone in the Northern Rocky Mountains experienced positive directional selection. Their study was published in Nature Ecology and Evolution in April 2017.. "Here, in Boechera stricta we are capturing that moment of selection - the moment when the subpopulation with the inversion takes over from the pre-inversion genotype and outcompetes it," said DOE JGI Plant Program Head Jeremy Schmutz, a co-author on the study. "The inversion fixes a set of alleles in the population. Here the set of fixed alleles improves survivability over the previous genotypes." Schmutz is also the co-director of the HudsonAlpha ...

The roots, leaves and flowers of the dandelion plant are a potent and healthy herbal medicine, although folks might think those yellow dots popping up in their landscape are just nuisance weeds. Not so, as reported by Reset.me, who emphasizes that the botanical name for dandelion - Taraxacum officinal - aptly describes its medicinal potential. Taraxacum translates into an "inflammation curative." Officinal means that the lowly dandelion is revered as a bona fide, official medicinal plant. The use of the dandelion plant as a healing agent "predates written records," but it is understood that the Greeks and the Chinese used dandelion compounds to aid in digestion, and as a liver tonic and diuretic.

While the dandelion is considered a weed by many gardeners and lawn owners, and difficult to eliminate with its long taproot, the plant has also been prized over the centuries for several culinary and medicinal uses. Dandelions are grown commercially on a small scale as a leaf vegetable. The plant can be eaten cooked or raw in various forms, such as in soup or salad. They are probably closest in character to mustard greens. Usually the young leaves and unopened buds are eaten raw in salads, while older leaves are cooked. Raw leaves have a slightly bitter taste. Dandelion salad is often accompanied with hard boiled eggs.. Dandelion flowers can be used to make dandelion wine. The recipe usually contains citrus fruit. Another recipe using the plant is dandelion flower jam. Ground roasted dandelion root can be used as a coffee substitute. Drunk before meals, it is believed to stimulate digestive functions. Sold in most health food stores, often in a mixture, it is considered an excellent cleansing ...
Dandelion - the word comes from the french dent de lion meaning tooth of a lion. Herbalists absolutely love the dandelion… unfortunately, homeowners do not!

Turns out they are a nutritional powerhouse, brimming with minerals and vitamins! Truly, one mans weed is another mans salad!. For most, the dandelion is an unwelcome invader, but as a beekeeper, I can appreciate that it was european settlers who introduced the dandelion to the midwest as food for the honey bee (as it turns out, the settlers brought the honeybees too!)

The dandelion sure gets a bad rap in suburbia. The other day I caught my neighbor using a leaf blower to blow the puff balls off the dandelions in my yard so they wouldnt blow into his perfectly groomed lawn.

Ottawa, Canada As I pondered the economic state of my mountain village in Nepal after a visit this summer, I noticed a number of anomalies. While someone from almost every household is working in a foreign country and has been sending money back for years, I could not find much improvement in the material or spiritual wealth of the village. I could not find the remittance money working for the betterment of the villagers. Obviously the village has changed in many ways as the thatch roofs are replaced by tin roofs, ropes are made not of Babiyo (Eulaliopsis binata) but of plastic; containers are made of not copper or wood but of aluminum; and polyester and nylon have replaced cotton. There is reduced diversity of crops and reduced production of food, but virtually unchanged poverty and hardship. A Dalit man had committed suicide by hanging himself from a tree the night I reached there, and many had done similar deeds in the recent years an emerging but tragic phenomenon in the village.

Hm. Mores happened here since I wandered off. So… in order…. heteromeles-Ive heard that the case in Astragalus (the genus of plants, mind you, not the bone; not being too familiar with skeletons, I was a bit baffled the first time I stumbled across that one) is much the same as in Eriogonum; multiple markers have been applied without yielding any substantial resolution. Ive been working on another genus (Boechera, in Brassicaceae) with similar problems; 7 nuclear loci give good resolution of a good chunk of the relationships, but there are still a fair number of big polytomies & poorly-supported nodes.. Dartian-"Which is actually fair enough (and was never in dispute, at least not by me) - but it then follows that your whole original comment was largely irrelevant in the context of this discussion.". Well, I was responding to stuff mentioned in Darrens article. Seemed relevant.. Regarding mtDNA-it certainly does provide good phylogenetic inferences some, probably most, of the time*. ...

The rate of seed consumption increased after seed dispersal. This may be explained by the concurrent increase in activity density as carabids aggregated at sites where seeds were abundant. However, because predator abundance and seed consumption are poorly correlated (cf. Figs 2 and 4), it is also possible that predators learn to eat dandelion seeds when their availability increases (a functional response III, Begon et al. 1990), although behavioural studies would be needed to test this hypothesis.. Adults of the specialized consumer, Amara montivaga, appeared on the experimental sites at the time of maximum dandelion flowering (Fig. 1) and before the onset of seed dispersal (Fig. 4). This is consistent with observations of A. montivaga feeding on dandelion flowers (P. Saska, personal observation). The activity density of A. montivaga also increased with the numbers of dandelion seeds dispersing, suggesting that aggregation of this species in dandelion patches explained the increased predation. ...

Dandelion root, ubiquitous in lawns and gardens, is widely-used for cooling and cleansing the liver; it is excellent in herbal formulas for hepatitis, cirrhosis, and liver toxicity. It increases the flow of bile and has been used for a variety of liver-associated illnesses. Dandelion has anti-carcinogenic, estrogen-lowering, and blood cholesterol-lowering capabilities. It also helps with headaches, emotional swings before or during menstruation, acne, red, irritated eyes, mood swings, and other problems related to "liver heat" and is a strong diuretic. In Chinese medicine dandelion root is taken internally and applied topically for abscesses and nodules. Additionally, it is used to increase lactation and clear liver heat when there are symptoms such as painfully inflamed eyes. Dandelion root tea is also a famous specific for breast cancer but should be taken in conjunction with other blood purifying herbs, such as sarsaparilla, red clover, and burdock root, as well as appropriate ...
Suzanne Collins, Mockingjay. Maybe you are wondering why the quote above is in this post. What does it have to do with the medical qualities of dandelion? Nothing. But it could be counted as one of those small things that make our lives more beautiful or it could be perceived as hope. Fortunately, the dandelions attributes dont stop at its beauty.. Dandelions (family Asteraceae, genus Taraxacum) have been known as medicinal herbs since Antiquity. It is a marvel plant indeed. When consumed they can provide calcium, potassium, manganese, iron, magnesium, phosphorus, sodium, zinc and vitamins such as C, E, K, B1, B2, B3, B5, B6, B9 and other nutrients (source: USDA Nutrient Database).. They are said to have diuretic properties and are also effective in case of constipation or gallbladder issues. Its high content in nutritive salts are effective against acids in the blood and it can soothe irritated stomachs and promote better food appetite and proper digestion. I guess theres no need to ...

Indian Wild Strawberry is a wild flower which has a bad reputation. I thought this invasive groundcover was poisonous, but around the world many eat not just the berry but the whole plant. The internet is full of information on the plants health and medicinal benefits. Duchesnea indica has many common names. Indian Strawberry, False Strawberry, Mock Strawberry, and She Mei are a few of its nicknames. In fact the plant is now placed in the Rose Family with the scientific name of Potentilla indica, (poh-ten-TIL-ah inn-DEE-kuh). The Rosoideae (Rose Family) has been subject to reorganization based on recent genetic analysis. It has been shown that both the wild strawberries (formerly Fragaria) and the Indian strawberries (formerly Duchesnea) are actually all part of the larger Potentilla within the Rose Family. This miniature plant looks like a common edible strawberry plant except for size and a yellow rather than white flower. This wildflower will grow anywhere from shade to full sun. The ...

The best example mentioned here is the dandelion plant. There s a very good chance that you already have dandelions growing on your land or near your home. Notoriously hardy and prolific, dandelions are all-too-often spurned as persistent pests. For this reason, they are cut down, weeded out, and treated with all kinds of chemical herbicides, but no matter what people throw at them, dandelions always seem to grow back. Could it be possible that such a resilient plant could also promote resilience within our own health as well, if we consume it? The answer is a resounding yes. If you live with dandelions in close proximity, you are very blessed indeed because you have a superfood, and one of nature s most potent medicines, in your midst. It is said that every part of the dandelion has a specific medicinal purpose - its roots being particularly beneficial for liver cleansing in the spring time. Dandelion greens are extremely nutritious and can be used in salads. They are particularly delicious ...

... (from Greek ἔντομος, entomos, "that which is cut in pieces or engraved/segmented", hence "insect"; and -λογία, -logia[1]) is the scientific study of insects, a branch of arthropodology. At some 1.3 million described species, insects account for more than two-thirds of all known organisms,[2] date back some 400 million years, and have many kinds of interactions with humans and other forms of life on earth. It is a specialty within the field of biology. Though technically incorrect, the definition is sometimes widened to include the study of terrestrial animals in other arthropod groups or other phyla, such as arachnids, myriapods, earthworms, land snails, and slugs.. Like several of the other fields that are categorized within zoology, entomology is a taxon-based category; any form of scientific study in which there is a focus on insect related inquiries is, by definition, entomology. Entomology therefore includes a cross-section of topics as diverse as molecular genetics, ...
See "Species of Trillium" below.. Trillium (trillium, wakerobin, tri flower, birthroot) is a genus of about 40-50 species of spring ephemeral perennials, native to temperate regions of North America and Asia.. It used to be treated in the family Trilliaceae or Trillium family, a part of the Liliales or Lily order. The AGP II treats Trilliaceae as a synonym of the family Melanthiaceae.. The above ground parts of Trilliums are scapes with three large, leaf-like bracts with the true leaves reduced to underground papery coverings around the rhizomes.. Typical species are Trillium grandiflorum (Large-flowered Trillium) in eastern North America and Trillium ovatum (Western Trillium). Both have white flowers that turn pink as they age.. Picking a trillium seriously injures the plant by preventing the leaf-like bracts from producing food for the next year. A plant takes many years to recover. For this reason in Michigan[1] and Minnesota[2] it is illegal to pick and/or transplant trilliums from public ...
A gametophyte is the haploid, multicellular phase of plants and algae that undergo alternation of generations, with each of its cells containing only a single set of chromosomes.. The gametophyte produces male or female gametes (or both), by a process of cell division called mitosis. The fusion of male and female gametes produces a diploid zygote, which develops by repeated mitotic cell divisions into a multicellular sporophyte. Because the sporophyte is the product of the fusion of two haploid gametes, its cells are diploid, containing two sets of chromosomes. The mature sporophyte produces spores by a process called meiosis, sometimes referred to as "reduction division" because the chromosome pairs are separated once again to form single sets. The spores are therefore once again haploid and develop into a haploid gametophyte.. In mosses, liverworts and hornworts (bryophytes), the gametophyte is the commonly known phase of the plant. An early developmental stage in the gametophyte of mosses ...
