Genome Analysis of South American Elymus (Triticeae) and Leymus (Triticeae) Species Based on Variation in Repeated Nucleotide Sequences
UC Davis UC Davis Previously Published Works Title Genome analysis of South American Elymus (Triticeae) and Leymus (Triticeae) species based on variation in repeated nucleotide sequences. Permalink https://escholarship.org/uc/item/54w48156 Journal Genome, 40(4) ISSN 0831-2796 Authors Dubcovsky, J Schlatter, AR Echaide, M Publication Date 1997-08-01 DOI 10.1139/g97-067 Peer reviewed eScholarship.org Powered by the California Digital Library University of California Genome analysis of South American Elymus (Triticeae) and Leymus (Triticeae) species based on variation in repeated nucleotide sequences Jorge DU~COVS~~,A.R. Schlatter, and M. Echaide Abstract: Variation in repeated nucleotide sequences (RNSs) at the level of entire families assayed by Southern blot hybridization is remarkably low within species and is a powerful tool for scrutinizing the origin of allopolyploid taxa. Thirty-one clones from RNSs isolated from different Triticeae genera were used to investigate the genome constitution of South American Elymus. One of these clones, pHch2, preferentially hybridized with the diploid H genome Hordeum species. Hybridization of this clone with a worldwide collection of Elymus species with known genome formulas showed that pHch2 clearly discriminates Elymus species with the H genome (StH, StHH, StStH, and StHY) from those with other genome combinations (Sty, StStY, StPY, and StP). Hybridization with pHch2 indicates the presence of the H genome in all South American Elymus species except Elymus erianthus and Elymus mendocinus. Hybridization with additional clones that revealed differential restriction fragments (marker bands) for the H genome confirmed the absence of the H genome in these species. Differential restriction fragments for the NS genome of Psathyrostachys were detected in E. -
Halophytic Hordeum Brevisubulatum Hbhak1 Facilitates Potassium Retention and Contributes to Salt Tolerance
International Journal of Molecular Sciences Article Halophytic Hordeum brevisubulatum HbHAK1 Facilitates Potassium Retention and Contributes to Salt Tolerance Haiwen Zhang 1, Wen Xiao 1,2, Wenwen Yu 1,2, Ying Jiang 1 and Ruifen Li 1,* 1 Beijing Key Laboratory of Agricultural Genetic Resources and Biotechnology, Beijing Agro-Biotechnology Research Center, Beijing Academy of Agriculture and Forestry Sciences, Beijing 100097, China; [email protected] (H.Z.); [email protected] (W.X.); [email protected] (W.Y.); [email protected] (Y.J.) 2 Beijing Key Laboratory of Plant Gene Resources and Biotechnology for Carbon Reduction and Environmental Improvement, College of Life Sciences, Capital Normal University, Beijing 100048, China * Correspondence: [email protected]; Tel.: +86-10-51503257 Received: 28 June 2020; Accepted: 20 July 2020; Published: 25 July 2020 Abstract: Potassium retention under saline conditions has emerged as an important determinant for salt tolerance in plants. Halophytic Hordeum brevisubulatum evolves better strategies to retain K+ to improve high-salt tolerance. Hence, uncovering K+-efficient uptake under salt stress is vital for understanding K+ homeostasis. HAK/KUP/KT transporters play important roles in promoting K+ uptake during multiple stresses. Here, we obtained nine salt-induced HAK/KUP/KT members in H. brevisubulatum with different expression patterns compared with H. vulgare through transcriptomic analysis. One member HbHAK1 showed high-affinity K+ transporter activity in athak5 to cope with low-K+ or salt stresses. The expression of HbHAK1 in yeast Cy162 strains exhibited strong activities in K+ uptake under extremely low external K+ conditions and reducing Na+ toxicity to maintain the survival of yeast cells under high-salt-stress. -
Origin, Divergence, and Phylogeny of Asexual Epichloë Endophyte in Elymus Species from Western China
RESEARCH ARTICLE Origin, Divergence, and Phylogeny of Asexual Epichloë Endophyte in Elymus Species from Western China Hui Song1,2, Zhibiao Nan1,2* 1 Key Laboratory of Grassland Agro-Ecosystems, Lanzhou, 730020, P. R. China, 2 College of Pastoral Agriculture Science and Technology, Lanzhou University, Lanzhou, 730020, P. R. China * [email protected] Abstract Asexual Epichloë species are likely derived directly from sexual Epichloë species that then lost their capacity for sexual reproduction or lost sexual reproduction because of interspecif- ic hybridization between distinct lineages of sexual Epichloë and/or asexual Epichloë spe- cies. In this study we isolated asexual Epichloë endophytes from Elymus species in western China and sequenced intron-rich regions in the genes encoding β-tubulin (tubB) and trans- lation elongation factor 1-α (tefA). Our results showed that there are no gene copies of tubB OPEN ACCESS and tefA in any of the isolates. Phylogenetic analysis showed that sequences in this study Citation: Song H, Nan Z (2015) Origin, Divergence, formed a single clade with asexual Epichloë bromicola from Hordeum brevisubulatum, and Phylogeny of Asexual Epichloë Endophyte in which implies asexual Epichloë endophytes that are symbionts in a western Chinese Ely- Elymus Species from Western China.

Comparative Cytogenetics 10(4): 465–481. doi: 10.3897/CompCytogen.v10i4.9666 Abstract Molecular karyotypes of H. bogdanii Wilensky, 1918 (2n = 14), and H. brevisubulatum Link, 1844 ssp. brevisubulatum (2n = 28), were characterized by physical mapping of several repetitive sequences. A total of 18 repeats, including all possible di- or trinucleotide SSR (simple sequence repeat) motifs and satel- lite DNAs, such as pAs1, 5S rDNA, 45S rDNA, and pSc119.2, were used as probes for fluorescence in situ hybridization on root-tip metaphase chromosomes. Except for the SSR motifs AG, AT and GC, all the repeats we examined produced detectable hybridization signals on chromosomes of both species. A detailed molecular karyotype of the I genome of H. bogdanii is described for the first time, and each repetitive sequence is physically mapped. -

Acta Biologica Sibirica 7: 49–61 https://doi. org/10.3897/abs.7.e58204 Abstract Elaeagnus angustifolia L. (Russian olive) is a deciduous small tree or large multi-stemmed shrub that becomes invader in different countries all other the world. It is potentially invasive in some regions of Russia. In the beginning of 20th century, it was introduced to the steppe region of Altai Krai (Rus- sia, southwestern Siberia) to prevent wind erosion. During last 20 years, Russian olive starts to create its own natural stands and to influence on native vegetation. This article presents the results of eco- coenotic survey of natural plant communities dominated by Elaeagnus angustifolia L. first described for Siberia and the analysis of their possible syntaxonomic position. The investigation conducted during summer season 2012 in the steppe region of Altai Krai allows revealing one new for Siberia association Elytrigio repentis–Elaeagnetum angustifoliae and no-ranged community Bromopsis inermis–Elae- agnus angustifolia which were included to the Class Nerio–Tamaricetea, to the Order Tamaricetalia ramosissimae. -

White, Jr. Mariusz Tadych2 Department of Plant Biology and Pathology, Rutgers University, New Brunswick, New Jersey 08901-8520 Abstract: Nomenclatural rule changes in the International Code of Nomenclature for algae, fungi and plants, adopted at the 18th International Botanical Congress in Melbourne, Australia, in 2011, provide for a single name to be used for each fungal species. The anamorphs of Epichloë species have been classified in genus Neotyphodium, the form genus that also includes most asexual Epichloë descendants. A nomenclatural realignment of this monophyletic group into one genus would enhance a broader understanding of the relationships and common features of these grass endophytes. Based on the principle of priority of publication we propose to classify all members of this clade in the genus Epichloë. We have reexamined classification of several described Epichloë and Neotyphodium species and varieties and propose new combinations and states. In this treatment we have accepted 43 unique taxa in Epichloë, Copyright 2014 by The -

(Poaceae), or true grasses, the fifth-largest plant family in the world, are of great importance in terms of human life and civilization. Therefore, understanding the spatial distribution of the family members is important for botanists, plant producers, and breeders. Turkey is one of two gene centers of this family. In this study, the spatial distribution of Triticeae in Turkey was mapped in geographic information systems (GIS) by utilizing a large number of specimens collected from 1006 georeferenced sampling sites between 2004 and 2010. Canonical correspondence analysis (CCA) was carried out in order to understand the spatial distribution of determined taxa. Environmental data for CCA were extracted from the available environmental raster map layers of Turkey. We identified and mapped a total of 76 species including 42 annuals and 34 perennials. CCA indicated that 6 environmental variables, namely potential evapotranspiration, elevation, distance to seas, maximum temperature, slope, and longitude, are the most effective in explaining the spatial distribution of the 12 annual species. -
Pyrrolizidine Alkaloids and Homospermidine Synthases in Grasses (Poaceae)
Pyrrolizidine alkaloids and homospermidine synthases in grasses (Poaceae) Dissertation zur Erlangung des Doktorgrades der Mathematisch‐Naturwissenschaftlichen Fakultät der Christian‐Albrechts‐Universität zu Kiel vorgelegt von Anne‐Maria Wesseling Kiel, 2017 Erster Gutachter: Prof. Dr. Dietrich Ober Zweite Gutachterin: Prof. Dr. Eva H. Stukenbrock Tag der mündlichen Prüfung: 27.02.2017 Zum Druck genehmigt: 27.02.2017 Thesis abstract The specialized metabolism of plants (also called secondary metabolism) and the evolution of proteins are two fascinating and active fields of biological research which overlap in the subject of the present doctoral thesis: pyrrolizidine alkaloid biosynthesis. On the one hand, pyrrolizidine alkaloids (PAs) represent a typical group of plant specialized metabolites. These compounds are produced only by specific flowering plant taxa and are important for the plant’s interactions with its environment. In the case of PAs, the compounds are mainly known as chemical defense molecules protecting the plant from herbivory. On the other hand, this specialized biosynthetic pathway provides interesting subjects for the study of protein evolution. The production of PAs in plants relies on the enzymatic activity of homospermidine synthases (HSS) which evolved from a gene duplicate of a deoxyhypusine synthase (DHS), a ubiquitous and essential enzyme of primary metabolism. The evolutionary history of the HSS is especially fascinating as the gene evolved several times independently in different flowering plant taxa. The range of flowering plants species that produces PAs is wide and includes several grass species (family Poaceae). While there is extensive literature on HSS biochemistry and evolution as well as on natural occurrences and the structural diversity of PAs in general, only very little of it deals with PAs produced by the members of the grass family. -
