Last name: MALBERT First name: Yannick Title: Flavonoid glucodiversification with engineered sucrose-active enzymes Speciality: Ecological, Veterinary, Agronomic Sciences and Bioengineering, Field: Enzymatic and microbial engineering. Year: 2014 Number of pages: 257 Flavonoid glycosides are natural plant secondary metabolites exhibiting many physicochemical and biological properties. Glycosylation usually improves flavonoid solubility but access to flavonoid glycosides is limited by their low production levels in plants. In this thesis work, the focus was placed on the development of new glucodiversification routes of natural flavonoids by taking advantage of protein engineering. Two biochemically and structurally characterized recombinant transglucosylases, the amylosucrase from Neisseria polysaccharea and the α-(1→2) branching sucrase, a truncated form of the dextransucrase from L. Mesenteroides NRRL B-1299, were selected to attempt glucosylation of different flavonoids, synthesize new α-glucoside derivatives with original patterns of glucosylation and hopefully improved their water-solubility. -

The area was nominated by the National Forest as a candidate RNA in 1986 to preserve an example of the Sierra Nevada mixed conifer forest for the South Coast Range Province. The RNA as defined in this report covers 2963 acres (1199 ha). The boundaries differ from those originally proposed by the National Forest (map 5, and see discussion of boundaries in later section). -

Silvipriya, Manakadan Asha Asokan* Department of Pharmaceutical Chemistry, Amrita School of Pharmacy, Amrita Viswa Vidyapeetham University, AIMS Health Sciences Campus, Kochi, Kerala, India *Corresponding Author Email: [email protected] Article Received on: 20/04/14 Revised on: 08/05/14 Approved for publication: 22/06/14 DOI: 10.7897/2230-8407.0506103 ABSTRACT Cancer is a disease affecting any part of the body and in comparison with normal cells there is an elevated level of lipoxygenase enzyme in different cancer cells. Thus generation of lipoxygenase enzyme inhibitors have suggested being valuable. Individual variation was identified by the functional effects of Single Nucleotide Polymorphisms (SNPs). 696 SNPs were identified from the ALOX12 gene, out of which 73 were in the coding non-synonymous region, from which 8 were found to be damaging. In silico analysis was performed to determine naturally occurring flavonoids such as isoflavones having the basic 3- phenylchromen-4-one skeleton for the pharmacological activity, like Genistein, Diadzein, Irilone, Orobol and Pseudobaptigenin. O-methylated isoflavones such as Biochanin, Calycosin, Formononetin, Glycitein, Irigenin, 5-O-Methylgenistein, Pratensein, Prunetin, ψ-Tectorigenin, Retusin and Tectorigenine were also used for the study. Other natural products like Aesculetin, a coumarin derivative; flavones such as ajoene and baicalein were also used for the comparative study of these natural compounds along with acteoside and nordihydroguaiaretic acid (antioxidants) and active inhibitors like Diethylcarbamazine, Zileuton and Azelastine as standard for the computational analysis. -

Perennial Grain Legume Domestication Phase I: Criteria for Candidate Species Selection

Temperate-adapted perennial grain legumes, though currently non-existent, might be uniquely situated as crop plants able to provide relief from reliance on synthetic nitrogen while supplying stable yields of highly nutritious seeds in low-input agricultural ecosystems. As such, perennial grain legume breeding and domestication programs are being initiated at The Land Institute (Salina, KS, USA) and elsewhere. This review aims to facilitate the development of those programs by providing criteria for evaluating potential species and in choosing candidates most likely to be domesticated and adopted as herbaceous, perennial, temperate-adapted grain legumes. We outline specific morphological and ecophysiological traits that may influence each candidate’s agronomic potential, the quality of its seeds and the ecosystem services it can provide. -

Federal law requires a non-federal landowner who wishes to conduct activities that may harm (“take”) threatened or endangered wildlife on their land to obtain an incidental take permit from the U.S. Fish and Wildlife Service. State law requires a non-federal public landowner who wishes to conduct activities that may harm threatened or endangered plants to obtain a permit from the Oregon Department of Agriculture. -
Enemy of My Enemy: Can the Rhizosphere Biota of Vincetoxicum Rossicum Act As Its “Ally” During Invasion?
Enemy of my Enemy: Can the Rhizosphere Biota of Vincetoxicum rossicum Act as its “Ally” During Invasion? by Angela Dukes A Thesis presented to The University of Guelph In partial fulfillment of the requirements for the degree of Master of Science in Environmental Biology Guelph, Ontario, Canada © Angela Dukes, November 2017 ABSTRACT Enemy of my Enemy: Can the Rhizosphere Biota of Vincetoxicum rossicum Act as its “Ally” During Invasion? Angela Dukes Advisors: Dr. Pedro Antunes University of Guelph, 2017 Dr. Kari Dunfield The ‘Enemy of my enemy’ (EE) is a major hypothesis in invasion ecology. It states that a non-native invader ‘accumulates generalist pathogens, which limit competition from indigenous competitors’. Few empirical studies have tested the EE hypothesis in plant invasions, especially on biotic rhizosphere interactions. Here, the EE hypothesis was tested by applying rhizosphere biota from the invasive plant Vincetoxicum rossicum (VIRO) to five co-occurring native plant species, and four native legume species, respectively. Each of the native plant species, and VIRO were grown under controlled conditions for three months, either in presence or absence of soil biota from VIRO invaded and non-invaded soils. Rhizosphere biota from invaded areas had variable effects among native plants (including legumes). It was concluded that the accumulation of rhizosphere enemies that ‘spill’ onto native plants may not be a major factor in the invasive success of VIRO. The EE hypothesis was not supported. iii ACKNOWLEDGEMENTS I deeply appreciated the patience of my supervisors: Dr. Kari Dunfield and Dr. Pedro Antunes.

The chemical structures of the isolated compounds were elucidated by 1D- and 2D-NMR analyses as well as MS spectroscopic data. The results suggest that flavonoids are characteristic of both plants. In the DPPH radical scavenging assay, (3 R)-vestitol (5) and 1234567890();,: 1234567890();,: isoquercetin (24) possessed the strongest antioxidative IC50 values of 42.20 µg/mL and 45.63 µg/mL, respectively, and their values were comparable to that of the positive control catechin (IC50 42.98 µg/mL).
