Proceedings Of The Workshop On Adaptation Of Plants To Soil Stresses, J.W. Maranville, V.C. Baligar, R.R. Duncan, J. M. Yohe

INTSORMIL Impacts and Bulletins

Sustainable production of food and forage with a focus on plant adaptation to stress environments will be a continued priority for developing countries in the future. Since many areas of the world which support substantial human populations are drought prone, such as the subsaharan African zone and others, the primary focus has been on drought. However, one of the greatest restraints to sustainability of agriculture worldwide is the lack of sufficient soil nutrients for crop growth, or other soil constraints such as acidity or salinity which hinder crop production substantially.

Optimizing soil fertility or amending acid and saline soils to …

The Population Biology And Demography Of Cimicifuga Rubifolia Kearney And The Genetic Relationships Among North American Cimicifuga Species, Rebecca Ann Cook

Doctoral Dissertations

In this beginning study of the population biology of Cimicifuga species, the life history and demography of the long-lived herbaceous perennial, Cimicifuga rubifolia Kearney, were investigated, the genetic structure of some of its populations was studied, and an investigation of the genetic relationships among the North American species was begun.

The life history and demography were monitored in two populations, one of approximately 1400 individuals (1987-1990) and the second of about 400 individuals (1988-1990). A model of leaf area was used to determine the leaf area (photosynthetic size) of individuals and this was followed during the study. Relationships between the …

Byenup Hill Catchment Report : Carlecatup Catchment Land Conservation District, Justin Hardy

Agriculture reports

The Byenup Hill Catchment is situated just west of Graham's Well which was a major watering point for early travellers. The area was first settled around 1890 and some of the names associated with early settlement are Hinchey, Dennis, Bilney, Holding and Gabette. Clearing with axes was a slow process and most of the sheep were run in the bush in areas free from poison bush. A reasonable number of trees were left standing and the last clearing was done in the 1980's. The first signs of salt appeared in the 1930's and advanced with increased clearing.

On The Relative Importance Of Floral Color, Shape, And Nectar Rewards In Attracting Pollinators To Mimulus, Steven D. Sutherland, Robert K. Vickery Jr.

Great Basin Naturalist

Pollinator preferences were observed for the six species of section Erythranthe of the genus Mimulus using greenhouse-grown plants placed in a meadow in the Red Butte Canyon Natural Area, Salt Lake County, Utah. The principal pollinators were hummingbirds and bumble bees. Hummingbirds preferred the species with the most reflexed tubular flowers regardless of color, whereas bumblebees preferred pink. lavender, or yellow flowers to red flowers regardless of shape. Results for the six species were confirmed by observations of F₂ hybrid recombinant plants selected such that flower color could be held constant and flower shape varied and vice versa.

Leptospira Genomes Are Modified At 5'-Gtac, David Ralph, Quideng Que, James L. Van Etten, Michael Mcclelland

Department of Plant Pathology: Faculty Publications

Genomic DNAs of 14 strains from seven species of the spirochete Leptospira were resistant to cleavage by the restriction endonuclease RsaI 1 (5'-GTAC). A modified base comigrating with m⁴C was detected by chromatography. Genomic DNAs from other spirochetes, Borrelia group VS461, and Serpulina strains were not resistant to h a 1 digestion. Modification at 5'-GTAm⁴C may occur in most or all strains of all species of Leptospira but not in all genera of spirochetes. Genus-wide DNA modification has rarely been observed in bacteria.

The Polymerase Chain Reaction And Plant Disease Diagnosis, Joan M. Henson, Roy C. French

Department of Plant Pathology: Faculty Publications

The polymerase chain reaction (PCR) provides a simple, ingenious method to exponentially amplify specific DNA sequences by in vitro DNA synthesis. Three essential steps to PCR (Figure 1) include (a) melting of the target (b) annealing of two oligonucleotide primers to the denatured DNA strands, and (c) primer extension by a thermostable DNA polymerase (123). Newly synthesized DNA strands serve as targets for subsequent DNA synthesis as the three steps are repeated up to 50 times. The specificity of the method derives from the synthetic oligonucleotide primers, which base-pair to and define each end of the target sequence to be …

Arkansas Rice Research Studies 1992, B. R. Wells

Arkansas Agricultural Experiment Station Research Series

The research reports in this publication represent one year of results; therefore, these results should not be used as a basis for longterm recommendations. Several research reports in this publication dealing with soil fertility also appear in Arkansas Soil Fertility Studies 1992, Arkansas Agricultural Experiment Station Research Series 425. This duplication is the result of the overlap in research coverage between the two series and our effort to inform Arkansas rice producers of all the research being conducted with funds from the rice check-off.

Flora Of The Quindalup Dunes Between Swan And Irwin Rivers, Western Australia, E A. Griffin

Research Reports

A study designed to determine the variation in the composition of the vegetation on the coastal Holocenes and deposits between Perth and Geraldton is described. The study was based on 545 sites at which descriptions of the geology, landform, soil and vegetation and a complete list of flora were made.The floristic composition of these sites varied considerably. Numerical classification showed some quite distinct communities and others which seemed part of a multi-dimensional continuum. Several factors appeared to be instrumental in the variation in composition. Landforms (incipient fore dunes, dunes or plains) were a major factor. So too were proximity to …

Treatment Of Pea (Pisum Sativum L.) Protoplasts With Dna-Damaging Agents Induces A 39-Kilodalton Chloroplast Protein Immunologically Related To Escherichia Coli Reca, Heriberto D. Cerutti, H. Z. Ibrahim, A. T. Jagendorf

Center for Plant Science Innovation: Faculty and Staff Publications

Organisms must have efficient mechanisms of DNA repair and recombination to prevent alterations in their genetic information due to DNA damage. There is evidence for DNA repair and recombination in plastids of higher plants, although very little is known at the biochemical level. Many chloroplast proteins are of eubacterial ancestry, suggesting that the same could be true for the components of a DNA repair and recombination system. A 39-kD protein, immunologically related to Escherichia coli RecA, is present in chloroplasts of pea (Pisum sativum L.). Bandshift gel assays suggest that it binds single-stranded DNA. Its steady-state level is increased …

Dna Strand-Transfer Activity In Pea (Pisum Sativum L.) Chloroplasts, Heriberto D. Cerutti, A. T. Jagendorf

Center for Plant Science Innovation: Faculty and Staff Publications

The occurrence of DNA recombination in plastids of higher plants is well documented. However, little is known at the enzymic level. To begin dissecting the biochemical mechanism(s) involved we focused on a key step: strand transfer between homologous parental DNAs. We detected a RecA-like strand transfer activity in stromal extracts from pea (Pisum sativum L.) chloroplasts. Formation of joint molecules requires Mg2+, ATP, and homologous substrates. This activity is inhibited by excess single-stranded DNA (ssDNA), suggesting a necessary stoichiometric relation between enzyme and ssDNA. In a novel assay with Triton X-100-permeabilized chloroplasts, we also detected strand invasion of the …

Evidence For Virus-Encoded Glycosylation Specificity, Ing-Nang Wang, Yu Li, Quideng Que, Meenakshi Bhattacharya, Leslie C. Lane, William G. Chaney, James L. Van Etten

Department of Plant Pathology: Faculty Publications

Four spontaneously derived serologically distinct classes of mutants of the Paramecium bursaria chlorella virus (PBCV-1) were isolated using polydonal antiserum prepared against either intact PBCV-1 or PBCV-1-derived serotypes. The oligosaccharide(s) of the viral major capsid protein and two minor glycoproteins determined virus serological specificity. Normally, viral glycoproteins arise from host-specific glycosylation of viral proteins; the glycan portion can be altered only by growing the virus on another host or by mutations in glycosylation sites of the viral protein. Neither mechanism explains the changes in the glycan(s) of the PBCV-1 major capsid protein because all of the viruses were grown in …
