Morphological and Anatomical Study of Bidens Pilosa Var.Pdf (440.3
1 Morphological and Anatomical Study of Bidens pilosa var. minor (Blume.) Sher. From Tribe Heliantheae Dr Ngu Wah Win1 & Min Htay Wai Linn2 Abstract In this research, morphology and anatomy of Bidens pilosa var. minor (Blume) Sher. of tribe Heliantheae belonging to the family Asteraceae were studied, photomicrographed and described. The plant is annual erect herb. Leaves are trifoliolate compound and the florets of rays and disc in a head are bisexual and monoecious heads are also found. In anatomical characters, although endodermis are inconspicuous only in roots, it is conspicuous in stem and root. The stomata types are anomocytic and vascular bundles are bicollateral, open and covered by one-layer of bundle sheath. The resulting characters are valuable for the identification of study species for further researchers. Key words – Asteraceae, endodermis, vascular bundles, bicollateral Introduction Asteraceae also called Sunflower family is one of the most important economic family and the second largest of flowering plant families. It consists of several tribes. Its flowers have two types of florets. Disc florets are in the center of head and ray florets in the outer. Many plants of Asteraceae family are economically important as weed, ornamentals, medicinal, green vegetables and poisonus plants. Commercially the flowers of this Asteraceae family are very famous of their colourful florets and beautiful petals. Several plants of this family are commonly cultivated for ornamental purpose in the gardens plots and field. The studied species of this Asteraceae family are native of America, Africa, India and all warmer countries (Grierson 1980). The study species is widely distributed in Pyin Oo Lwin of Mandalay Region. -

ENH1308 Biology and Management of Spanish Needles (Bidens spp.) in Ornamental Crop Production1 Yuvraj Khamare, Chris Marble, Shawn Steed, and Nathan Boyd2 Introduction Family All eight species of Bidens in Florida are commonly referred Asteraceae (Compositae) to as Spanish needles or beggar-ticks (Wunderlin, 2019). This document focuses on Bidens alba and B. pilosa, which Other Common Names are common weeds in container nurseries and landscapes Blackjack, beggar-ticks, cobbler’s pegs, farmer’s friends in Florida. Both of these species are very similar in appear- ance and biology and are capable of interbreeding (Norton, Life Span 1991). Due to the similarity between these species, they are Both species are annual or short-lived perennials sometimes recognized as one in the literature (Wunderlin, 2019). Their differences are distinctive, however, as B. pilosa Habitat flowers usually do not have petals while B. alba usually does. B. alba is also more widely distributed throughout Spanish needles occur in many different habitats, ranging Florida than B. pilosa.

B. pilosa has been traditionally used in foods and medicines without obvious adverse effects. Despite significant progress in phytochemical and biological analyses of B. pilosa over the past few years, comprehensive and critical reviews of this plant are anachronistic or relatively limited in scope. The present review aims to summarize up-to-date information on the phytochemistry, pharmacology, and toxicology of B. pilosa from the literature. B. pilosa is a major crop weed, threat to native fauna, and a physical nuisance. It is considered one of the most noxious annual weeds in East Africa. B. pilosa had strong allelopathic effects which is beneficial in enhancing its capacity in interspecific competition and to promote its invasion. It is used as a folkloric medicine for the treatment of various diseases and used extensively by indigenous people, especially in Africa, for the treatment of a variety of ailments. Various compounds with biological activity, mainly, polyacetylenes and flavonoids have been isolated and identified in all parts of the plant. Pharmacognostic studies and phytochemical screenings of B. pilosa had also shown the presences of other compounds with biological activities which include terpenes, essential oils, tannins, polysaccharides, phenols, amino acids, ascorbic acid and organic acids. -

In the present study, we investigated the effects of an ethyl acetate extract of Bidens pilosa leaves on pulmonary hypertension in rats induced by intraperitoneal injection of monocrotaline (50 mg/kg) in Wistar rats. One week later, the animals were treated orally with the extract (100 or 200 mg/kg) or sildenafil (1.7 mg/kg) used as control drug for fourteen days. Three weeks after monocrotaline injection, pulmonary arterial pressure and lung weight was significantly increased in the vehicle-treated group, whereas they were attenuated by the extract treatment at the highest dose studied (200 mg/kg). -
Pollination Ecology of Bidens Pilosa L. (Asteraceae)
Taiwania 63(2): 89-100, 2018 DOI: 10.6165/tai.2018.63.89 Pollination ecology of Bidens pilosa L. (Asteraceae) Usharani BUDUMAJJI and Aluri Jacob SOLOMON RAJU* Department of Environmental Sciences, Andhra University, Visakhapatnam 530 003, India. *Corresponding author: email:[email protected]; Phone: +91-9866256682 (Manuscript received 6 January 2018; accepted 29 March 2018; online published 30 April 2018) ABSTRACT: Information on pollination ecology is essential to understand the sexual reproduction in Bidens pilosa L. The study is aimed at providing details of sexual system, breeding system, pollination mechanism, pollinators, seed dispersal modes and germination aspects B. pilosa based mostly on field study. Paper chromatography technique was used for recording sugar and amino acid types in the nectar since they are important to evaluate the pollination syndrome. The study indicates that B. pilosa displays vegetative, flowering and fruiting phases throughout the year. The plant produces heterogamous capitula with all ray florets opening on the first day and disc florets opening on the next four consecutive days. The ray florets are sterile while disc florets are fertile, dichogamous, protandrous, herkogamous, self-compatible, self-pollinating (vector-mediated) and facultative xenogamous. The disc florets display secondary pollen presentation. The tubate corolla, production of sucrose-rich nectar with essential and non-essential amino acids, and tri-colporate, echinate tri-colpate pollen grains in disc florets suggest entomophily. The plant is accordingly entomophilous but principally psychophilous. Disc florets produce non-dormant, long and short cypselas from the same capitulum. Seed dispersal is polychorous involving anemochory, anthropochory, zoochory and ombrohydrochory. The long cypselas of disperse farther away from parental sites and germinate readily under a wide range of conditions while short cypselas disperse to short distances and germinate under specific germination conditions at parental sites/in similar habitats. -

O. T. Ashafa and A. J. Afolayan* Centre for Phytomedicine Research, Department of Botany, University of Fort Hare, Alice 5700, South Africa. Accepted 5 July, 2009 Bidens pilosa L. is a medicinal plant in many regions of the world. The antimicrobial activity of the methanol, acetone and water extracts from the root of the South African ecotype was evaluated using agar dilution method. The extracts showed significant activity against all the bacteria and some fungi species tested in this study. The methanol extract inhibited all Gram-positive and Gram-negative bacteria with minimum inhibitory concentrations ranging from 5 to 10 mg/ml. Although the water extract did not inhibit any of the bacteria, the acetone extract was able to suppress the growth of Staphylococcus aereus, Staphylococcus epidermidus, Escherichia coli and Klebsella pnuemoniae in the same concentration range as the methanol extract. All the extracts exhibited 100% inhibition against Penicilium notatum at 0.1 mg/ml. In the same pattern, all the extracts showed good activity against Aspergillus niger but none could inhibit Aspergillus flavus. The best activity was observed in the methanol extract against most bacteria and fungal strains, which suggest the use of organic solvent extraction for good antimicrobial activity. Our results have shown that extracts from the root of this species could inhibit both Gram-positive and Gram-negative bacteria as well as some fungi species. -

The most important is Lettuce mosaic virus (LMV), a potyvirus found worldwide transmitted by seeds and aphids, in a non-persistent manner. LMV causes quite variable symptoms, including mosaic, dwarfing, failure to form proper heads, and sometimes necrotic reactions. Cultivars carrying the mo11 and mo12 genes have resistance to the common strains, although most (mo breaking seed transmitted) strains can overcome this resistance. At least three species of tospovirus, including Tomato spotted wilt virus (TSWV), Tomato chlorotic spot virus (TCSV) and Groundnut ringspot virus (GRSV) causes significant losses, especially during summer, in which high populations of thrips vectors can be found in the field. Tospoviruses causes systemic necrosis and plant death. During the cooler season (May to September), two viruses have been found associated with big-vein disease, Mirafiori lettuce big-vein virus (MLBVV) which belongs to the genus Ophiovirus and Lettuce big-vein associated virus (LBVaV; genus Varicosavirus). LBVaV and MLBVV are both transmitted by the soil-borne fungus Olpidium brassicae. Lettuce mottle virus (LeMoV, genus Sequivirus); Cucumber mosaic virus (CMV, genus Cucumovirus), and Bidens mosaic virus (BiMV, genus Potyvirus) are also found to cause mosaic symptoms on lettuce, although their incidence in lettuce fields is low throughout the year. -
Flower Heads in Asteraceae—Recruitment of Conserved
Elomaa et al. Horticulture Research (2018) 5:36 Horticulture Research DOI 10.1038/s41438-018-0056-8 www.nature.com/hortres REVIEW ARTICLE Open Access Flower heads in Asteraceae—recruitment of conserved developmental regulators to control the flower-like inflorescence architecture Paula Elomaa 1,YafeiZhao1 and Teng Zhang 1 Abstract Inflorescences in the Asteraceae plant family, flower heads, or capitula, mimic single flowers but are highly compressed structures composed of multiple flowers. This transference of a flower-like appearance into an inflorescence level is considered as the key innovation for the rapid tribal radiation of Asteraceae. Recent molecular data indicate that Asteraceae flower heads resemble single flowers not only morphologically but also at molecular level. We summarize this data giving examples of how rewiring of conserved floral regulators have led to evolution of morphological innovations in Asteraceae. Functional diversification of the highly conserved flower meristem identity regulator LEAFY has shown a major role in the evolution of the capitulum architecture. Furthermore, gene duplication and subsequent sub- and neofunctionalization of SEPALLATA- and CYCLOIDEA-like genes in Asteraceae have been shown to contribute to meristem determinacy, as well as flower type differentiation—key traits that specify this large family. Future challenge is to integrate genomic, as well as evolutionary developmental studies in a wider selection of Asteraceae fl 1234567890():,; 1234567890():,; 1234567890():,; 1234567890():,; species to understand -
