Reduction Of Lignin In Tobacco Through The Expression Of An Antisense Caffeic Acid O-Methyltransferase, Ti̇jen Talas Oğraş, Kemal Kazan, Nermi̇n Gözükirmizi

Turkish Journal of Botany

Caffeic acid O-methyltransferase (COMT) is a methylation enzyme involved in the early stages of lignin biosynthesis. To examine the effect of antisense expression of a heterologous COMT gene on lignification, an antisense construct of a cDNA encoding a caffeic acid O-methyltransferase ( pOMT8) from Stylosanthes humilis Humb., Bonpl. & Kunth Fabaceae was transferred into tobacco via Agrobacterium tumefaciens. A large number of kanamycin-resistant shoots were recovered after transformation, and randomly selected putative transgenics were analysed for stable integration of the transgene into their genomes. The analyses demonstrated that antisense expression of pOMT8 resulted in reductions in total COMT activity, which …

A Neglected Lichen Collection From Turkey: Berkhamsted School Expedition 1971, Volker John, Mark R. D. Seaward, Jeff W. Beatty

Turkish Journal of Botany

Discovery of the unpublished report of the Berkhamsted School lichenological expedition to Turkey in 1971 and a reappraisal of the complementary (almost complete) collections in The Natural History Museum, London (BM), have added considerably to our knowledge of the Turkish lichen flora. In all, 171 taxa are listed, of which 21 species are new to Turkey and 220 records are new to one ore more of the 11 provinces; many additional records pre-date those made as a result of the upsurge of interest in the Turkish lichen flora over the past decade.

Monogenic Segregations In Backcross Progenies Of Capsicum Baccatumx Two Interspecific F_1 Hybrids And Some Possible Explanations For Distorted Segregation Ratios In Capsicum, A. Naci̇ Onuş, Barbara Pickersgill

Turkish Journal of Botany

Monogenic segregations of certain morphological and isozymic characters were studied in backcross progenies of Capsicum baccatumL. ( Solanaceae) x two interspecific F_1 hybrids and distorted segregation ratios were noted. It was observed that isozyme markers Est-5, Idh-1, Pgm-2, and Pgi-2, and morphological marker gene P for fruit persistence showed distorted segregation ratios in the first backcross generation of both C. baccatumHawkes 6489 (P.G.Smith) x F_1 ( C. baccatum Hawkes 6489 x Capsicum cardenasii Heiser Smith) and C. baccatum SA219 (P.G.Smith) x F_1 ( C. baccatum SA219 x Capsicum eximiumA.T.Hunz). Both progenies and an excess of individuals carrying alleles inherited from …

Germin-Like Oxalate Oxidase Activity Increase In Auxin-Treated Wheat Coleoptiles, Mahmut Çalişkan, Andrew C. Cuming

Turkish Journal of Botany

Oxalic acid or more commonly its salts, oxalates, are widely distributed throughout the plant kingdom. Oxalic acid is generally considered an inert product of metabolism and its accumulation is toxic to tissues. Therefore, the enzymes degrading oxalic acid have received considerable attention. Oxalate oxidase is an oxidoreductase which degrades oxalate into CO_2 and H_2O_2 . Recently, oxalate oxidase was shown to have high amino acid homology with germin proteins and at the same time cereal germin proteins were shown to have oxalate oxidase activity. Germin gene expression was shown to be auxin responsive. It was well demonstrated that coleoptile cells …

Structure Of The Stigma And Style In Capsicum Eximiumand The Effects Of Pollination, A. Naci̇ Onuş

Turkish Journal of Botany

Since the stigma surface provides the first point of contact for pollen grains, the initial pollen-pistil interaction takes place between these two structures. It is, therefore, important to understand the stucture of the stigma, as well as the style, in order to reveal the nature of pollen-pistil interaction. The aim of this study was to gather more information about interactions between pollen and pistil in Capsicum eximium A.T.Hunz Solanaceae by studying immature, mature unpollinated and mature pollinated styles. It was found that most features of the stigma and style of C. eximiumresembled those of other genera in the Solanaceae.

Use Of Randomly Amplified Polymorphic Dna-Polymerase Chain Reaction (Rapd-Pcr) To Distinguish North American Populations Of Acroptilon Repens (L.) Dc, Raul A. Ruiz

Theses and Dissertations - UTB/UTPA

Sixty U.S. populations of Acroptilon repens collected in 1998 were analyzed using RAPD-PCR. Each population was represented by five specimens gathered from each location. A total of 301 specimens were examined using two Operon Technologies, RAPD-PCR primers (A 10 and C04). The DNA amplification products produced through the PCR process were electrophoretically separated to produce DNA fragments ranging from 100 to 2000 base-pairs in length. The 60 U.S. populations sampled, produce ten RAPD banding pattern types using A 10 primer and seventeen pattern types with C04. Genetic variation within and among the populations was low, however, one dendogram did show …

Conservation Implications Of Genetic Variation In Three Rare Species Endemic To Florida Rosemary Scrub, Rebecca W. Dolan, Rebecca Yahr, Eric S. Menges, Matthew Halfhill

Scholarship and Professional Work - LAS

Habitat conversion and fire suppression during the last 50 yr have greatly reduced and altered Florida scrub vegetation, resulting in threats to the persistence of its unique flora. As part of a larger conservation project, we investigated patterns of isozyme variation in three rare perennial scrub plants with overlapping ranges endemic to Florida rosemary scrub on the Lake Wales Ridge. All three species have low levels of genetic variation, comparable to or lower than those generally reported for rare plants with restricted geographic ranges. Liatris ohlingerae has more than twice the expected heterozygosity of the other two species, with little …

Ferns, Robert H. Mohlenbrock

Illustrated Flora of Illinois

Perhaps no other group of plants attracts more interest among both professional and amateur botanists than ferns. As early as 1846, when one of the first lists of Illinois plants was published, sixteen species of ferns were already known in the state. The longtime interest of a great many people makes the distribution of ferns better known than that of any other group of plants in Illinois.

This detailed account of ferns and fern-allies was first published in 1967 as the first volume in the series The Illustrated Flora of Illinois. Eminent botanist Robert H. Mohlenbrock has now revised Ferns …

Review Of A Classification Of North American Biotic Communities By David E. Brown, Frank Reichenbacher, Susan E. Franson, Robert B. Kaul

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

This is the latest of many efforts over the past century to classify North America's natural, undisturbed biological communities as they existed in pre-agrarian times and in many places continue to exist today. Its authors' stated objective is to integrate existing works into a hierarchical synthesis that can lead to a standardized system for researchers, land managers, conservation groups, and government agencies. To that end, the authors have modified and expanded David Brown's earlier classification for the Southwest to cover the continent, defined here as the area from the Panama Canal to the Arctic, including Greenland and some of the …

Arkansas Agricultural Experiment Station Research Series

Weed control is economically important for production of rice, a major crop in Arkansas. These findings summarize efforts of the team of Arkansas scientists working on weed control strategies for rice during 1998. Various technologies were evaluated in field studies involving the major weed problems and rice production systems used in the state. Results from these studies will add to the arsenal of weed control options for producers. The preliminary results reported here generally warrant further testing for more advanced findings and for the labeling of new technologies and, finally, are the basis for updating safe, effective, and economical recommendations …

Gender Variation In Croton Californicus (Euphorbiaceae), James Lynwood Smith Ii

Loma Linda University Electronic Theses, Dissertations & Projects

Croton californicus Muell. Arg. (Euphorbiaceae) is a subshrub suspected of being dimorphic with phase choices. Gender variation in C. californicus was studied in natural populations of southern California for three years (1994-96) to observe patterns of gender !ability. Some sites exhibited significantly male-biased sex ratios, and these sites often had the greatest number of monoecious morphs, cosexual plants with unisexual flowers. Gender variation was quantified for cosexual plants by calculating the Estimated Floral Gender (EFG) which varied from 1.00 (female) to 0.00 (male). The distribution of the EFG was highly skewed towards maleness. Monoecious individuals were then categorized by …
