Origin and Age of Australian Chenopodiaceae

Using a previously published rbcL phylogeny of the Amaranthaceae–Chenopodiaceae alliance (Kadereit et al. 2003) and new ITS phylogenies of the Camphorosmeae and Salicornieae, we conclude that Australia has been reached in at least nine independent colonization events: four in the Chenopodioideae, two in the Salicornieae, and one each in the Camphorosmeae, Suaedeae, and Salsoleae. Where feasible, we used molecular clock estimates to date the ages of the respective lineages. The two oldest lineages both belong to the Chenopodioideae (Scleroblitum and Chenopodium sect. Orthosporum/Dysphania) and date to 42.2–26.0 and 16.1–9.9 Mya, respectively. Most lineages (Australian Camphorosmeae, the Halosarcia lineage in the Salicornieae, Sarcocornia, Chenopodium subg. Chenopodium/Rhagodia, and Atriplex) arrived in Australia during the late Miocene to Pliocene when aridification and increasing salinity changed the landscape of many parts of the continent. The Australian Camphorosmeae and Salicornieae diversified rapidly after their arrival. The molecular-clock results clearly reject the hypothesis of an autochthonous stock of Chenopodiaceae dating back to Gondwanan times. -
Variability of Hypericins and Hyperforin in Hypericum Species from the Sicilian Flora
Chemistry & Biodiversity, Volume17, Issue1, January 2020, e1900596 Variability of Hypericins and Hyperforin in Hypericum Species from the Sicilian Flora Silvia Lazzara, Alessandra Carrubba, Edoardo Napoli Abstract Within Sicilian flora, the genus Hypericum (Guttiferae) includes 10 native species, the most popular of which is H. perforatum. Hypericum’s most investigated active compounds belong to naphtodianthrones (hypericin, pseudohypericin) and phloroglucinols (hyperforin, adhyperforin), and the commercial value of the drug is graded according to its total hypericin content. Ethnobotanical sources attribute the therapeutic properties recognized for H. perforatum, also to other Hypericum species. However, their smaller distribution inside the territory suggests that an industrial use of such species, when collected from the wild, would result in an unacceptable depletion of their natural stands. This study investigated about the potential pharmacological properties of 48 accessions from six native species of Hypericum, including H. perforatum and five ‘minor’ species, also comparing, when possible, wild and cultivated sources. The variability in the content of active metabolites was remarkably high, and the differences within the species were often comparable to the differences among species. No difference was enlightened between wild and cultivated plants. A carefully planned cultivation of Hypericum seems the best option to achieve high and steady biomass yields, but there is a need for phytochemical studies, aimed to identify for multiplication the genotypes with the highest content of the active metabolites. Introduction According to the available literature, 10 Hypericum species have been identified in Sicily: H. aegypticum L., H. androsaemum L., H. australe TEN., H. hircinum L., H. perfoliatum L., H. perforatum L., H. pubescens BOISS., H. -

More than 150 species occur worldwide, although dodder is most prevalent in the Americas. The genus Cuscuta is in the Cuscutaceae family, but sometimes it is included in the family Convolvulaceae (morning glories). Dodder species vary in the number of different host species they can infect. Some, such as C. salina, are in rather restricted sites such as salty marshes, flats, and ponds on just a few host plant species. Others, such as C. pentagona (C. campestris in some publications), are found on many crop and weed species including alfalfa, asparagus, melons, safflower, sugarbeet, tomato, field bindweed (Convolvulus arvensis), lambsquarters (Chenopodium album), and pigweed (Amaranthus species). C. indecora, also has a wide host range that includes alfalfa and weeds such as field bindweed, five-hook Dodder, Cuscuta species, on bassia (Bassia hyssopifolia), lambsquarters, and Russian thistle (Salsola tragus). tomato. Japanese dodder, C. japonica, which is native to Asia, recently has been found in California attacking and covering ornamental shrubs and fruit trees, with a Table 1.

In Vitro Shoot Proliferation of Hypericum Perforatum L. Through Indirect and Direct Plant Regeneration
Journal of Medicinal Plants and By-products (2017) 1: 81-89 Original Article In vitro shoot Proliferation of Hypericum perforatum L. through Indirect and Direct Plant Regeneration Manizhe Abdollahpoor1*, Siamak Kalantari1, Majid Azizi2 and Yusef Ali Saadat3 1Department of Horticultural Science, Tehran University, Karaj, Iran. 2Department of Horticultural Science, Ferdowsi University of Mashhad, Mashhad, Iran. 3Central Agriculture and Natural Resource of Fars Province, Shiraz, Iran. Article History: Received: 04 December 2016 /Accepted in revised form: 15 March 2017 © 2013 Iranian Society of Medicinal Plants. All rights reserve Abstract Hypericum perforatum L. (St. Johns’ wort) is the most commercially important species of the genus Hypericum and contains a wide range of components including naphthodianthrones, phloroglucinols, tannins, xanthones, phenolic acids and essential oil. In order to establish an efficient protocol for regeneration, the effects of explant type and plant growth regulators on direct and indirect shoot regeneration in H. perforatum were evaluated. According to obtained results the media supplemented with 0.1 mg l-1 Benzyl Adenine (BA) was effective for shoot proliferation from shoot tip explants of H. perforatum that showed the highest shoots number (15.5 shoots per explant) and shoot height (2.07 cm). In second experiment a method for rapid micro propagation of H. perforatum through indirect plant regeneration from calli has been developed. The results demonstrated that a combination of auxin and cytokinin was needed for optimum callus induction and leaf segments were suitable explant for callus induction in H. perforatum. Callus induction was observed in most studied treatments but the highest callus volume (1.43 cm3) was obtained by leaf segments in media supplemented with 0.25 mg l-1 2,4- Dichlorophenoxyacetic acid (2,4-D)+1 mg l-1 Kinetin. -
An Illustrated Key to the Amaranthaceae of Alberta
AN ILLUSTRATED KEY TO THE AMARANTHACEAE OF ALBERTA Compiled and writen by Lorna Allen & Linda Kershaw April 2019 © Linda J. Kershaw & Lorna Allen This key was compiled using informaton primarily from Moss (1983), Douglas et. al. (1998a [Amaranthaceae], 1998b [Chenopodiaceae]) and the Flora North America Associaton (2008). Taxonomy follows VASCAN (Brouillet, 2015). Please let us know if there are ways in which the key can be improved. The 2015 S-ranks of rare species (S1; S1S2; S2; S2S3; SU, according to ACIMS, 2015) are noted in superscript (S1;S2;SU) afer the species names. For more details go to the ACIMS web site.
