Cyperaceae family biology discussion

The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges.The family is large, with some 5,500 known species described in about 90 genera, the largest being the true sedges genus Carex with over 2,000 species. These species are widely distributed, with the centers of diversity for the group occurring in tropical Asia and tropical South America Cyperaceae (sedges) represent the third largest monocot family in terms of species diversity, after Orchidaceae (orchids) and Poaceae (grasses), with c. 90 genera and c. 5,500 species (Govaerts et al. 2018).The family has an almost cosmopolitan distribution (Simpson et al. 2011), and occupies a broad range of habitats from rain forests to tundra (Bruhl 1995; Smith et al. 2009; Simpson et al.

Department of Biology (Botany), Universidad Autónoma de Madrid, Campus Cantoblanco, 28049 Madrid, Non-natural groups defined by morphological data are known all over Cyperaceae family due to the effect of homoplasy or symplesiomorphy (e.g., Larridon et al., 4 Discussion 4.1 Phylogenetic. Cronquist (1968) considered that the families are also related on account of some chemical data. Hegnauer (1963) has also supported the same view. Hutchinson (1959) believes that the origin of Grasses i.e., the family Poaceae (Gramineae) took place on parallel line with Cyperaceae through Juncaceae which was derived directly from Liliforean stock Kukkonen, I. 1967.

The family is commonly called carrot family. It was also named as Umbelliferae. It includes 295 genera and 2,850 species according to Willis. In India the family is represented by 180 species and 30 genera. The plants are distributed almost throughout the world except the arctic regions Division of family and chief genera: The Commelinaceae is divided into two sub-families and each with two tribes: Sub-family I. Commelinoideae: Guard cells mostly 4. Flowers zygomorphic. Tribe (i) Declinateae: Flower buds bent downwards and away from the inflorescence axis. Examples: Commelina, Floscopa etc. Tribe (ii) Inclinateae In the family Cyperaceae, the first C 4 evolution (Bulbostylis) has likely occurred between 19.6 (± 4.9) and 10.1 (± 3.6) Ma, but the other C 4 appearances all arose during the last 12 My , making C 4 sedges generally younger than their grass counterparts (Christin, Besnard, et al. 2008)

Phylogeny and Systematics of Cyperaceae, the Evolution and

  1. The cosmopolitan family Cyperaceae (Poales) contains 104-122 genera containing ca. 5,000 species, with the species diversity corresponding to 23 % of Poales (Bruhl 1995; Goetghebeur 1998; Govaerts et al. 2007).Sedges have been used for various purposes such as in medicine, as food, and as materials for craftwork (Simpson 2008).. One of the most extensive taxonomic studies on Cyperaceae was.
  2. Cyperaceae and Poaceae have traditionally been treated as related families (Cronquist, 1981). Recent cladistic analysis using molecular and morphological data confirms a closer relationship with Juncaceae, with the sedge clade consisting of Cyperaceae, Juncaceae, and Thurniaceae (Chase et al.,2000). Many species of Cyperaceae are heliophytes
  3. INTRODUCTION. The sedge genus Carex contains approx. 2000 species, making it one of the most species-rich angiosperm genera (Reznicek, 1990).The sedge family (Cyperaceae) exhibits diffuse centromeres (holocentric or holokinetic chromosomes), pseudomonad origin of pollen (except in the subfamily Mapanioideae; Simpson et al., 2003) and post-reductional meiosis (reviewed in Hipp et al., 2009)
  4. Euphorbiaceae Characters , formula , floral diagram & economic Importance is discussed in this biology article. Habit: Annual perennial Herbs, shrubs, or tree; most of plants are xerophytic; presence of milky juice
  5. Members of the Cyperaceae family exhibit an asymmetric microsporogenesis that results in the degeneration of three out of four meiotic products. Efforts have been made previously to describe the resulting structure, named the pseudomonad, but mechanisms concerning the establishment of cell domains, nuclear development, and programmed cell death are largely unknown
  6. The genus Carex L. belongs to the Cyperaceae family and is an enormous genus. It is one of the most vital genera of vascular plants in the environment [], with more than 2000 species widespread all over the world [] and nearly 500 species in China [].Carex species are widely used as a ground cover for home lawns as well as for slope stabilization in many parts of the world because of cold and.

The Australian Journal of Botany is an international journal publishing original research encompassing all plant groups including fossil plants. Plant science areas covered by the scope are as follows: ecology and ecophysiology, conservation biology and biodiversity, forest biology and management, cell and molecular biology, palaeobotany, reproductrive biology and genetics, mycology and. C 4-linked positive selection on this gene is tested using phylogenetic analyses of commelinoid monocots including all known major C 4 lineages in the Poaceae and Cyperaceae families (Sage 2004; Bruhl and Wilson 2007; Christin et al. 2008). Sites that underwent adaptive changes in C 4 plants are identified and compared among C 4 lineages The split of the two major lineages within the Entorrhizales (corresponding to the genera Entorrhiza and Juncorrhiza) took place somewhat later than the split between the host families Cyperaceae and Juncaceae, which was estimated to have happened during the Late Cretaceous and Paleogene according to recent datings [Cyperaceae—82.3 Mya (73.7-87.6 Mya), Juncaceae—71.8 Mya (51-87 Mya. Juncaceae and Cyperaceae are two families of monocotyledonous plants in which holocentric chromosomes are a synapomorphy (Greilhuber, DISCUSSION C-value and its influence on karyotype differentiation. From the point of view of karyotypes and chromosomal biology,. Our aim is to understand the evolution of species-rich plant groups that shifted from tropical into cold/temperate biomes. It is well known that climate affects evolutionary processes, such as how fast species diversify, species range shifts, and species distributions. Many plant lineages may have gone extinct in the Northern Hemisphere due to Late Eocene climate cooling, while some tropical.

Morphological, embryological, and palynological studies support the retention of Kyllinga as a genus distinct from Cyperus. Aspects of the life history of Kyllinga brevifolia Rottb are described The anther wall is four-layered The endothecial cells develop spiral thickenings and globular markings. Some cells of the secretory tapetum later become binucleate No dicot family is strictly C 4, and in all cases, the number of C 4 genera and species present in a family are in the minority, usually by a large degree. Only 4 dicot families (Amaranthaceae, Chenopodiaceae, Molluginaceae, Zygophyllaceae ) have more than 10% C 4 representation at the generic and species level, whereas seven families have only one identified genus with C 4 species

Discussion. Our phylogenetic tree of Cyperaceae CenH3 is congruent with the species phylogenies of Cyperaceae based on multiple nuclear and chloroplast markers (Márquez-Corro et al., 2019; Semmouri et al., 2019), suggesting that our dataset does not contain paralogous sequences resulting from ancient duplications.It is possible that our primers simply did not recognize potential paralogs 4 Discussion The historical biogeography and ecological diversification of Cyperaceae is evident in the distribution of sedge diversity across the climatically heterogeneous USA and Canada.

Taxa were selected to represent adequately all families of Poales. For the two largest families Cyperaceae and Poaceae, genera were chosen to represent the basal lineages as reconstructed by Musaya et al.

Cyperaceae are usually regarded as non-mycorrhizal, but the frequent observation of mycorrhizal fungi in their roots, sometimes even with arbuscules (Muthukumar et al. 2004; Veselkin et al. 2014a), has caused some authors to propose a possible classification of Cyperaceae as variable non-mycorrhizal-arbuscular mycorrhizal (NM-AM) family (Brundrett 2009) Medicinal Properties of Cyperus Species (Sedge Family, Cyperaceae) by Lata Maishaya Udari THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE -BIOLOGICAL SCIENCES IN THE GRADUATE SCHOOL, EASTERN ILLINOIS UNIVERSITY CHARLESTON, ILLINOIS 2018 I HEREBY RECOMMEND THAT THIS THESIS BE ACCEPTED A

While Cyperaceae have been inferred to have arisen in South America at the late Cretaceous, it was the migration of the ancestors of Carex to the Northern Hemisphere that was the catalyst for the major diversification of this lineage (Léveillé-Bourret et al., 2014, 2015, 2018a, 2018c; Spalink et al., 2016b) A recent molecular phylogenetic study revealed four distinct evolutionary lineages in the genus Costularia s.l. (Schoeneae, Cyperaceae, Poales).

Cyperaceae (sedges), Restionaceae (rushes) and Juncaceae (reeds), similar to Proteaceae, occur on some of the poorest soils in the south-west of Western Australia (Lamont, 1981; Meney et al., 1993)

We referred to the World Checklist of Selected Plant Families (WCSP; Govaerts et al., 2020) to guide nomenclature and authorities for the Cyperaceae taxa considered in this study. The 152 species of Schoenus included in our list include those accepted by the WCSP, as well as several new species published within the last two years that have yet to be added to the WCSP website (see Appendix S1 ) A ligule (from Latin: ligula strap, variant of lingula, from lingua tongue) is a thin outgrowth at the junction of leaf and leafstalk of many grasses (Poaceae) and sedges.A ligule is also a strap-shaped extension of the corolla, such as that of a ray floret in plants in the daisy family Asteraceae In the Cyperaceae family, which is the largest group of holocentric plants, chromosomes vary from n = 2 to n = 108 (Roalson, 2008). Although the lowest chromosome number in angiosperms is found in Rhynchospora tenuis ( n = 2), we can also find extraordinarily very high chromosomes numbers in other genera within this family, for instance in Carex ( Wieclaw et al., 2020 ) and Cyperus ( Roalson. 1 Introduction. Based on molecular DNA and morphological studies we presented a generic classification and hierarchical tree with detailed relationships of all subfamilies, tribes, and subtribes within the Poaceae (Soreng et al., 2015b).In the same year a comprehensive treatment of the Poaceae was completed by Kellogg that included, in addition to a generic classification outlining. The ultrastructural studies with C 4 Cyperaceae conducted in species from the four Kranz types have mainly examined species of tribe Cypereae (chlorocyperoid) and tribe Abildgaardieae (fimbristyloid) (Carolin et al. 1977 Carolin, R.C.; Jacobs, S.W.L. & Vesk, M. 1977.

Cyperus esculentus produces large amounts of oil as one of the main oil storage reserves in underground tubers, making this crop species not only a promising resource for edible oil and biofuel in food and chemical industry, but also a model system for studying oil accumulation in non-seed tissues. In this study, we determined the chloroplast genome sequence of the cultivated C. esculentus. Caustis deserti, commonly known as desert twig-rush, is a sedge that is native to a small area in the Goldfields-Esperance region of Western Australia to the east of Kalgoorlie.. References ↑ Caustis deserti Have you ever wondered why some flowers bloom in bunches while some others bloom vertically? No, that is no magic! There is pure science behind it. You must be aware of the term inflorescence. In this chapter, we will study more about inflorescence. We will also look at the various inflorescence types
