Subnuclear distribution of the entire complement of linker histone variants in Arabidopsis thaliana

Autor: J S Gantt, R Ascenzi

Publikováno v: Chromosoma. 108:345-355

Linker histones (e.g. H1, H5, H1 degrees ) are thought to exert control on chromatin function by restricting nucleosomal dynamics. All higher eukaryotes possess a diverse family of linker histones, which may exhibit functional specialization. Arabido

Nitrogen assimilation in alfalfa: isolation and characterization of an asparagine synthetase gene showing enhanced expression in root nodules and dark-adapted leaves

Autor: S N Twary, Susan S. Miller, Carroll P. Vance, R G Gregerson, Deborah A. Samac, P J Unkefer, L Shi, Hirofumi Yoshioka, J S Gantt

Publikováno v: The Plant Cell. 9:1339-1356

Asparagine, the primary assimilation product from N2 fixation in temperate legumes and the predominant nitrogen transport product in many plant species, is synthesized via asparagine synthetase (AS; EC 6.3.5.4). Here, we report the isolation and char

Immunogold localization of nodule-enhanced phosphoenolpyruvate carboxylase in alfalfa

Autor: J. S. Gantt, D. L. Robinson, Carroll P. Vance, S. M. Pathiran

Publikováno v: Plant, Cell and Environment. 19:602-608

Phosphoenolpyruvate carboxylase (PEPC; EC 4-1-1-31) plays a paramount role in providing carbon for synthesis of malate and aspartate in alfalfa (Medicago sativa L.) root nodules. PEPC protein and activity levels are highly enhanced in N2-fixing alfal

Plant cytosolic ribosomal protein S11 and chloroplast ribosomal protein CS17. Their primary structures and evolutionary relationships

Autor: M D Thompson, J S Gantt

Publikováno v: Journal of Biological Chemistry. 265:2763-2767

We have isolated cDNA clones specific for Arabidopsis thaliana cytosolic ribosomal protein S11 and plastid ribosomal protein CS17, both of which are encoded in the nuclear genome, through the use of the corresponding soybean and pea cDNAs as probes,

Decreased NADH glutamate synthase activity in nodules and flowers of alfalfa (Medicago sativa L.) transformed with an antisense glutamate synthase transgene

Autor: M A, Schoenbeck, S J, Temple, G B, Trepp, J M, Blumenthal, D A, Samac, J S, Gantt, G, Hernandez, C P, Vance

Publikováno v: Journal of experimental botany. 51(342)

Legumes obtain a substantial portion of their nitrogen (N) from symbiotic N2 fixation in root nodules. The glutamine synthetase (GS, EC 6.3.1.2)/glutamate synthase (GOGAT) cycle is responsible for the initial N assimilation. This report describes the

Molecular genetic analysis of the drought-inducible linker histone variant in Arabidopsis thaliana

Autor: R, Ascenzi, J S, Gantt

Publikováno v: Plant molecular biology. 41(2)

Linker histones are ubiquitous structural components of chromatin that have been shown to influence the expression of a subset of genes in diverse organisms. Plants contain a minor linker histone variant that is expressed in most tissues of all organ

Nodule Carbon Metabolism: Organic Acids for N2 Fixation

Autor: Gian B. Trepp, D. L. Robinson, J. S. Gantt, Susan S. Miller, B. T. Driscoll, D. A. Samas, Carroll P. Vance

Publikováno v: Biological Nitrogen Fixation for the 21st Century ISBN: 9789401061698

The energy burden (carbon (C) cost) imposed on plants for symbiotic nitrogen (N2) fixation is approximately 6 mg C · mg N reduced (Day, Copeland, 1991). Photosynthate, in the form of sucrose, is the ultimate source of carbon required for both N2 fix

A drought-stress-inducible histone gene in Arabidopsis thaliana is a member of a distinct class of plant linker histone variants

Autor: R, Ascenzi, J S, Gantt

Publikováno v: Plant molecular biology. 34(4)

We have isolated and characterized a gene, His1-3, encoding a structurally divergent linker histone in Arabidopsis thaliana. Southern and northern hybridization data indicate that A. thaliana expresses three single-copy linker histone genes, each enc

Molecular characterization of NADH-dependent glutamate synthase from alfalfa nodules

Autor: Susan S. Miller, J S Gantt, S N Twary, R G Gregerson, Carroll P. Vance

Alfalfa NADH-dependent glutamate synthase (NADH-GOGAT), together with glutamine synthetase, plays a central role in the assimilation of symbiotically fixed nitrogen into amino acids in root nodules. Antibodies previously raised against purified NADH-

Characterization of rps17, rp19 and rpl15: three nucleus-encoded plastid ribosomal protein genes

Autor: M D, Thompson, C M, Jacks, T R, Lenvik, J S, Gantt

Publikováno v: Plant molecular biology. 18(5)

Approximately two-thirds of the 55 to 60 plastid ribosomal proteins are encoded in the nucleus. Since the protein products of each of these genes are needed in equal amounts for ribosome assembly, their expression may be coordinately regulated by com
