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)

article{4213140, abstract = {In apomictic Boechera spp., meiotic diplospory leads to the circumvention of meiosis and the suppression of recombination to produce unreduced male and female gametes (i.e. apomeiosis). Here, we have established an early flower developmental staging system and have performed microarray-based comparative gene expression analyses of the pollen mother cell stage in seven diploid sexual and seven diploid apomictic genotypes to identify candidate factors for unreduced pollen formation. We identified a transcript unique to apomictic Boechera spp. called UPGRADE2 (BspUPG2), which is highly up-regulated in their pollen mother cells. BspUPG2 is highly conserved among apomictic Boechera spp. genotypes but has no homolog in sexual Boechera spp. or in any other taxa. BspUPG2 undergoes posttranscriptional processing but lacks a prominent open reading frame. Together with the potential of stably forming microRNA-like secondary structures, we hypothesize that BspUPG2 functions as a ...

Apomictic and Sexual Ovules of Boechera Display Heterochronic Global Gene Expression PatternsApomictic and Sexual Ovules of Boechera Display Heterochronic Global Gene Expression Patterns
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 ...

Speciation in flowering mustard plant driven by alleles adapted to local conditions - Genome Sequencing CenterSpeciation in flowering mustard plant driven by alleles adapted to local conditions - Genome Sequencing Center
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 ...

Dandelion root, a cancer cell killer, has a long history as medicine - Infinite UnknownDandelion root, a cancer cell killer, has a long history as medicine - Infinite Unknown
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. (RELATED: Learn more about natural remedies at Remedies.news). Traditional herbalists, both in the East and the West, have utilized the properties of the dandelion for liver support and as a blood purifier.

Dandelion - New World EncyclopediaDandelion - New World Encyclopedia
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 ...

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 long invasion | Lincoln EcologyThe long invasion | Lincoln Ecology
In a new study published in Austral Ecology, Nicola Day and Hannah Buckley of Lincoln University have looked at the fate of three closely related invasive species over three decades. The plant species Hieracium (Hawkweed, Asteraceae) are native to Europe but are invasive in many parts of the world where they often degrade native and pastoral grasslands. In New Zealand, three species in particular, H. lepidulum, H. pilosella, and H. praealtum, were introduced accidentally in grass-seed mixtures and cause major problems in high country areas. Day and Buckley wanted to know which ecological and environmental traits explained the spread of these species, whether these traits were important at all scales and whether they were the same for all three species. To test these ideas they were able to make use of a fantastic long term study. In the mid 1980s, 124 study sites were set up in high altitude tussock grasslands in Otago and southern Canterbury. Information about the plant species found at these ...

Comments for Wanted Weeds Part 1: The DandelionComments for Wanted Weeds Part 1: The Dandelion
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. Lawn care companies and homeowners with green grass seem to have quite the vendetta against this weed. If they only knew how helpful this amazing plant is they wouldnt waste so much effort trying to eradicate it from their yards.. The Chinese name for dandelion is Pu Gong Ying. It is commonly called dandelion or taraxicum (Herba Taraxaci). In Chinese medicine we place this herb in the category Clear Heat, Eliminate Toxins. We use it both internally and externally. Pu Gong Ying has antibacterial properties and reduces inflammation in the skin. We use it for sores, lesions, ulcerations and red rashes on the skin. It is also great for pus-filled abscesses when combined with other herbs. It is quite helpful to relive sore throat, too. In my clinical practice, I add Pu Gong Ying to almost ...

NOTES ON THE FLORAL MORPHOLOGY AND ANATOMY OF TESSMANNIANTHUS CARINATUS (MELASTOMATACEAE)NOTES ON THE FLORAL MORPHOLOGY AND ANATOMY OF TESSMANNIANTHUS CARINATUS (MELASTOMATACEAE)
Aceptado: 08/04/2014. INTRODUCTION. The genus Tessmannianthus Markgr. has seven species and is restricted to the Neotropical countries of Panama , Colombia , Ecuador , and Peru (Almeda 1990). It is considered to be a member of the tribe Merianieae (Renner, 1993). Species in the genus are medium to large trees reaching 40 meters tall making them amongst the largest members of Melastomataceae (Almeda 1990). Tessmannianthus flowers are also unusual in that they are extremely heterantherous, with the small set of stamens bifurcating at the apex into two distinct pores whereas the large stamens have a single pore. This extreme heteranthery is used to diagnose the genus and gives the name to the type species, T. heterostemon Markgr. (Markgraf 1927). Another less uncommon but noteworthy feature of the androecium in Tessmannianthus is that the larger series of stamens are opposite the sepals rather than the petals, as is the more frequent condition in heterantherous taxa (Almeda 1989, Mendoza-Cifuentes ...

Dandelion greens are a favorite springtime wild edible, but if you dont get them early enough, they begin to toughen.

EntomologyEntomology
... (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, ...

TrilliumTrillium
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 ...

Gametophytic apomixis3
  • Agamospermy occurs mainly in two forms: In gametophytic apomixis, the embryo arises from an unfertilized egg cell (i.e. by parthenogenesis) in a gametophyte that was produced from a cell that did not complete meiosis. (wikipedia.org)
  • Therefore, the genetic control of apomictic reproduction found in citrus (nucellar embryony) is quite complex compared to what has been reported for gametophytic apomixis. (citrusgenomedb.org)
  • However, plants can also produce seeds via asexual reproduction, avoiding the need for fertilization, in a process known as gametophytic apomixis (hereafter referred to as apomixis, see Glossary, Box 1 ). (biologists.org)
Meiosis2
  • Contrary to the sexual pathway, wherein the diversity of progeny is derived from meiotic recombination during gamete formation followed by parental gamete fusion and embryogenesis at fertilization, apomixis avoids meiosis during female gamete development, and embryogenesis initiates without fertilization. (beds.ac.uk)
  • Apomixis is the mechanism of seed production without involving the process of meiosis and syngamy. (saralstudy.com)
Apomictic5
  • Apomixis is the asexual production of seeds, so that apomictic seeds are clones of the mother plant. (grain.org)
  • In Poa pratensis the cDNA-AFLP method of mRNA profiling allowed us to visualize a total of 2248 transcript-derived fragments and to isolate 179 sequences that differed qualitatively or quantitatively between apomictic and sexual genotypes at the time of flowering when the primary stages of apomixis occur. (deepdyve.com)
  • Molecular markers linked to QTLs governing apomixis will be useful to assist selection of future apomictic rootstocks for citrus varieties. (citrusgenomedb.org)
  • Observed changes in small RNA targets and biogenesis pathways within sexual and apomictic ovaries will underlie future functional research into apomixis initiation in Hieracium . (beds.ac.uk)
  • As apomixis is not evident in major seed crops, isolation of genes from apomictic model species with the intention to transfer them to crops has been a major focus of research. (beds.ac.uk)
Fertilization7
  • In botany, apomixis is asexual reproduction without fertilization. (wikipedia.org)
  • In autonomous apomixis, seed development occurs without pollination and thus without fertilization of either the egg cell or the polar cell. (pnas.org)
  • Apomixis is a reproductive process in plants where seed are produced without the union (fertilization) of the egg cell and sperm (gametes) to form an embryo. (usda.gov)
  • Reproduction without fertilization (synonym to apomixis). (springer.com)
  • In another instance of apomixis, the ovule cells (2n) grow into an embryo opposite to fertilization. (gardenguides.com)
  • Sometimes apomixis includes embryo development as well as egg fertilization. (gardenguides.com)
  • Apomixis (including apospory and diplospory) is a type of reproduction that does not involve fertilization. (wikipedia.org)
Crops12
  • Since most major crops do not express natural apomixis, it is useful to understand the origin and maintenance of apomixis in natural plant systems. (cabi.org)
  • The utilization of apomixis in crops must consider the potential risks of pollen transfer and introgression into sexual crop fields, which might be overcome by using pollen-sterile or cleistogamous variants. (cabi.org)
  • This article examines apomixis research, and the main implications that transferring apomixis into crops may have for industry, farmers and the environment. (grain.org)
  • Uncommon in wild plants and rare in crops, apomixis is one of the most cherished dreams of plant breeders. (grain.org)
  • But in spite of earlier claims that its transfer into crops was around the corner, apomixis is proving elusive. (grain.org)
  • The most obvious benefit of introducing apomixis into crops would be to allow selecting an individual plant and propagate it as clones through its seeds. (grain.org)
  • Like genetic engineering, apomixis would demolish some of the species barriers that have contained the evolution of our crops. (grain.org)
  • As demonstrated by fruit crops, apomixis enables breeders to fix valuable traits and heterozygosity. (nature.com)
  • Use of apomixis in plant breeding could economize and speed delivery of new plant varieties by preserving unlinked complex traits, such as heterosis in hybrid crops, within a single seed generation. (beds.ac.uk)
  • There has been a great deal of interest in using apomixis in the development of uniform, true breeding, vigorous hybrids in many of the food and grain crops, but apomixis does not naturally occur in any of these major crops. (usda.gov)
  • Efforts to transfer apomixis to these crops from wild relatives using conventional breeding methods have not been successful. (usda.gov)
  • Crops that reproduce through apomixis conserve the same traits from one generation to the next, essentially locking in sought-after characteristics such as drought tolerance or high nutritional value. (rural21.com)
Genes7
  • Isolation of candidate genes for apomixis in Poa pratensis L. (deepdyve.com)
  • We also narrowed the genetic locus responsible for citrus polyembryony, a form of apomixis, to an 80-kb region containing 11 candidate genes. (nature.com)
  • This study provides new insights into citrus apomixis and constitutes a promising resource for the mining of agriculturally important genes. (nature.com)
  • Alice: Coexpression and transcriptome analyses identify active apomixis-related genes in Paspalum notatum leaves. (embrapa.br)
  • Identification of apomixis genes is confounded by the polyploid nature, high genome complexity and lack of genomic sequence integration with reproductive tissue transcriptomes in most apomicts. (beds.ac.uk)
  • Identification of genes regulating apomixis has been hindered due to limited genomic and transcriptomic resources available in apomict model species. (beds.ac.uk)
  • In this study, molecular tools were used to search for genes that are involved in the expression of apomixis. (usda.gov)
Polyploidy1
  • Polyploidy and apomixis may contribute to taxonomic difficulties by locking suites of traits together into morphologic forms. (efloras.org)
Types of apomixis3
  • Thus "normal asexual reproduction" of plants, such as propagation from cuttings or leaves, has never been considered to be apomixis, but replacement of the seed by a plantlet or replacement of the flower by bulbils were categorized as types of apomixis. (wikipedia.org)
  • Maheshwari used the following simple classification of types of apomixis in flowering plants: Nonrecurrent apomixis: In this type "the megaspore mother cell undergoes the usual meiotic divisions and a haploid embryo sac [megagametophyte] is formed. (wikipedia.org)
  • There are two main types of apomixis. (publishyourarticles.net)
Example of apomixis2
  • The first example of apomixis in citrus was reported in 1719, when Leeuwenhoek observed the development of two plantlets from the same seed 4 . (nature.com)
  • Recently, an example of apomixis in gymnosperms was discovered (see Pichot, C., et al, in the 5 July 2001 issue of Nature ). (biology-pages.info)
Boechera2
  • Boechera is the only among the more than 370 genera in the Brassicaceae where apomixis is well documented. (frontiersin.org)
  • In this review, we discuss the advantages of the Boechera genus to study apomixis, consider its modes of reproduction as well as the inheritance and possible mechanisms controlling apomixis. (frontiersin.org)
Paternal apomixis2
  • Male apomixis (paternal apomixis) involves replacement of the genetic material of an egg by the genetic material of the pollen. (wikipedia.org)
  • Is this paternal apomixis in a surrogate mother a desperate attempt to avoid extinction? (biology-pages.info)
Forms of asexual2
  • Some authors included all forms of asexual reproduction within apomixis, but that generalization of the term has since died out. (wikipedia.org)
  • How is the ability to reproduce by apomixis advantageous compared with other forms of asexual. (bartleby.com)
Facultative3
  • Facultative apomixis means that apomixis does not always occur, i.e. sexual reproduction can also happen. (wikipedia.org)
  • These findings suggest that the accessions analyzed may reproduce by facultative apomixis. (usda.gov)
  • Background: Semigamy in cotton is a type of facultative apomixis controlled by an incompletely dominant autosomal gene (Se). (ebscohost.com)
Reproductive1
  • Apomixis is a common feature of perennial plants, which occurs in ca . 60% of the British flora, but has been largely ignored by reproductive theoreticians. (royalsocietypublishing.org)
Koltunow1
  • R. A. Bicknell and A. M. Koltunow, "Understanding apomixis: recent advances and remaining conundrums," Plant Cell , vol. 16, pp. (hindawi.com)
Embryos2
  • Apomixis in citrus is sporophytic-the embryos develop from somatic nucellar cells-and very stable among commercial varieties, including sweet oranges, mandarins, grapefruits and lemons 7 . (nature.com)
  • Agricultural scientists would dearly love to convert these plants to apomixis: making embryos that are genetic clones of themselves rather than the product of sexual reproduction with its inevitable gene reshuffling. (biology-pages.info)
Embryo is formed2
  • In adventitious embryony (sporophytic apomixis), an embryo is formed directly (not from a gametophyte) from nucellus or integument tissue (see nucellar embryony). (wikipedia.org)
  • Falcinelli, Mario 2005-04-07 00:00:00 The essential feature of apomixis is that an embryo is formed autonomously by parthenogenesis from an unreduced egg of an embryo sac generated through apomeiosis. (deepdyve.com)
Citrus2
  • The emergence of apomixis-the transition from sexual to asexual reproduction-is a prominent feature of modern citrus. (nature.com)
  • This makes apomixis one of the host important traits in breeding programs for citrus rootstocks. (citrusgenomedb.org)
Asexual reproduction through seeds1
  • Asexual reproduction through seeds, or apomixis, is a process that holds much promise for agricultural advances. (usda.gov)
Embryony3
  • Adventitious embryony is another developmental pathway toward apomixis. (cabi.org)
  • Sporophytic apomixis, including nucellar embryony, is not as well studied. (nature.com)
  • One of the markers associated to apomixis (Apo2) is also associated to embryony type. (citrusgenomedb.org)
Occurs4
  • See also androgenesis and androclinesis described below, a type of male apomixis that occurs in a conifer, Cupressus dupreziana. (wikipedia.org)
  • In nature, apomixis is widespread but infr-equent: it occurs in around 10% of the 400 families of flowering plants, but only in 1% of the 40,000 species that make up those families. (grain.org)
  • Apomixis occurs in many of the warm-season grasses including buffelgrass. (usda.gov)
  • Apomixis occurs in more than 400 plant species belonging to ∼40 genera. (biologists.org)
Polystichoid ferns1
  • Among polystichoid ferns, apomixis evolved several times independently in three different clades. (wikipedia.org)
Hieracium1
  • Examples of apomixis can be found in the genera Crataegus (hawthorns), Amelanchier (shadbush), Sorbus (rowans and whitebeams), Rubus (brambles or blackberries), Poa (meadow grasses), Nardus stricta (Matgrass), Hieracium (hawkweeds) and Taraxacum (dandelions). (wikipedia.org)
Hybridization1
  • Many studies suggest that hybridization, either on diploid or polyploid cytotypes, is a major trigger for the formation of unreduced female gametophytes, which represents the first step toward apomixis, and must be combined to parthenogenesis, the development of an unfertilized egg cell. (cabi.org)
Occur3
  • Apomixis is reported to occur in about 10% of globally extant ferns. (wikipedia.org)
  • In sum, apomixis is now known to occur in five of the nine Boechereae genera. (frontiersin.org)
  • Polyploid forms and asexual seed production (apomixis) occur in some species. (efloras.org)
Reproduction11
  • In flowering plants, the term "apomixis" is commonly used in a restricted sense to mean agamospermy, i.e., clonal reproduction through seeds. (wikipedia.org)
  • Although the evolutionary advantages of sexual reproduction are lost, apomixis can pass along traits fortuitous for evolutionary fitness. (wikipedia.org)
  • in other words, that "obligate apomixis" is an artifact of insufficient observation (missing uncommon sexual reproduction). (wikipedia.org)
  • Apomixis, the asexual reproduction via seed, has many potential applications for plant breeding by maintaining desirable genotypes over generations. (cabi.org)
  • But their pollen is often viable, so that apomixis can also be transmitted through the more common mechanism of sexual reproduction. (grain.org)
  • Here, we report sexual reproduction in diploid Nevada , diploid Sandbergia , and tetraploid Cusickiella and aposporous apomixis in tetraploids of Polyctenium and Sandbergia . (frontiersin.org)
  • Apomixis refers to the asexual reproduction through seed, and a better understanding of the underlying mechanisms has great potential for applications in agriculture. (frontiersin.org)
  • Asexual reproduction through seed, called apomixis, is key in developing new crop varieties for widespread use. (rural21.com)
  • an organism reproducing by, or formed by, apomixis, nonsexual reproduction from an unfertilized ovum. (absp.org.uk)
  • relating to apomixis, nonsexual reproduction, from an unfertilized ovum. (absp.org.uk)
  • Other plants, especially weeds such as hawkweed and dandelions, can produce true seeds that are clones of themselves without sexual reproduction -- a still poorly understood process called apomixis. (ucdavis.edu)
Genera2
  • Recently, apomixis was reported in the Boechereae genera Borodinia and Phoenicaulis . (frontiersin.org)
  • Compounding the problem is that apomixis is common in several genera. (eol.org)
Traits1
  • Application of apomixis, or asexual seed formation, in crop breeding would allow rapid fixation of complex traits, economizing improved crop delivery. (beds.ac.uk)
Sexuality2
  • Despite its theoretical advantages, apomixis usually coexists with sexuality, suggesting 'hidden' disadvantages. (royalsocietypublishing.org)
  • Chi-square tests of independence were significant for both 1:1 ratios as expected with sexuality and 1:0 ratios as expected with apomixis. (usda.gov)
Species4
  • The combination of apomixis' capacity to create and stabilise new genetic combinations and to break the species barriers could lead to the 'asexual revolution', which some think could even dwarf the Green Revolution. (grain.org)
  • It is a widespread and well known group of over 375 species which reproduce by apomixis . (wikipedia.org)
  • In the past, a great deal of research has been conducted studying the genetics of apomixis in this grass, and because of this, buffelgrass is an excellent model species to use in learning more about apomixis. (usda.gov)
  • Consequently, understanding the genetic diversity of this species is relevant to the utilization and conservation of its germplasm resources, to population genetic studies, and to the evolution of apomixis in this dioecious species. (bioone.org)
Mechanisms2
  • Part I. The mechanisms of apomixis. (springer.com)
  • However, the molecular mechanisms underlying apomixis are currently poorly understood. (usda.gov)
Reproduce1
  • With this molecular marker, plant breeders can run a quick and inexpensive test when Brachiaria grasses are seedlings to identify whether they reproduce through apomixis. (rural21.com)
Agamospermy1
Genetic3
  • In discussions of the benefits genetic engineering can bring to small farmers, proponents love to point to apomixis - the production of cloned seed. (grain.org)
  • The genetic control of apomixis was studied in a 50-tree progeny derived from the cross C. volkameriana×P. trifoliata using 69 molecular markers and bulked segregant analysis. (citrusgenomedb.org)
  • Apomixis has been described in a close relative of Arabidopsis , Arabis holboellii ( 3 ), and some genetic data support a one or two gene control of apomixis ( 3 ), so we reasoned that a mutational approach in Arabidopsis might detect mutants displaying some components of apomixis. (pnas.org)
Genus1
  • Nosrati, H , Price, AH & Wilcock, CC 2010, ' No evidence of apomixis in matroclinal progeny from experimental crosses in the genus Fragaria (strawberry) based on RAPDs ', Euphytica , vol. 171, no. 2, pp. 193-202. (elsevier.com)
Hybrids3
  • If apomixis were well understood and harnessed, it could be exploited to indefinitely propagate superior hybrids or specific genotypes bearing complex gene sets. (deepdyve.com)
  • Many such hybrids use apomixis to propagate themselves. (biology-pages.info)
  • The many races of Kentucky bluegrass growing in lawns across North America and the many races of blackberries are two examples of sterile hybrids that propagate successfully by apomixis. (biology-pages.info)
Gametophytes1
  • In plants with independent gametophytes (notably ferns), the term is still used interchangeably with "apomixis", and both refer to the formation of sporophytes by parthenogenesis of gametophyte cells. (wikipedia.org)
Polyembryony1
Interspecific1
  • C. H. Park and M. Kato, "Apomixis in the interspecific triploid hybrid fern Cornopteris christenseniana (Woodsiaceae)," Journal of Plant Research , vol. 116, no. 2, pp. 93-103, 2003. (hindawi.com)
Pollen2
  • These have been attributed to either accidental selfing and/or pollen contamination, or apomixis. (elsevier.com)
  • Our results showed that the complete morphological similarity of progeny to the seed parent, even in recessive characteristics, cannot therefore be taken as evidence of apomixis, and may rather indicate the heterozygosity of the pollen parent, emphasising the need to use DNA markers for confirmation of apomixis. (elsevier.com)
Progeny1
  • The absence of apomixis among matroclinal progeny in this study casts doubt on previous reports of apomixis in Fragaria. (elsevier.com)
Evolution1
  • Also, a detailed analysis of evolution of the APOLLO apomixis-associated locus was performed. (preprints.org)
Loci1
  • Analysis of quantitative trait loci (QTLs) revealed the presence of six genomic positions (two in P. trifoliata and four in C. volkameriana) contributing individually up to 24% of the total variation for apomixis. (citrusgenomedb.org)
