Occurrence of indoleacetic acid in the bryophytes. Processes of Organic Evolution. Salt Tolerance in Phaseolus vulgaris.
Generally, most references will be to the primary literature i. Popular literature and the Internet should be used sparingly and with caution. Other sources such as book chapters and pamphlets typically have their own specific citation formats.
If necessary, be sure to find out what these formats are and use them appropriately. For a much more detailed discussion about writing scientific papers, consult: Council of Biology Editors, Inc. This guide is based on a paper by Gubanich, A. Writing the scientific paper in the investigative lab.
Examples from the scientific literature that illustrate material in various sections of a scientific paper. Revision of the theory of phototropism in plants: However, determination of the absolute amounts of indoleacetic acid IAA in the agar blocks, using a physicochemical assay following purification, showed that the IAA was evenly distributed in the blocks from the illuminated and shaded sides. In the blocks from the shaded and dark-control halves the amounts of IAA were 2.
Chromatography of the diffusates prior to the Avena curvature test demonstrated that the amounts of two growth inhibitors, especially of the more polar one, were significantly higher in the agar blocks from the illuminated side than in those from the shaded side and the dark control.
These results show that the basic experiment from which the Cholodny-Went theory was derived does not justify this theory. The data rather indicate that phototropism is caused by the light-induced, local accumulation of growth inhibitors against a background of even auxin distribution, the diffusion of auxin being unaffected.
Inducible defensive responses in plants are known to be activated locally and systematically by signaling molecules that are produced at sites of pathogen or insect attacks, but only one chemical signal, ethylene, is known to travel through the atmosphere to activate plant defensive genes.
Methyl jasmonate, a common plant secondary compound, when applied to surfaces of tomato plants, induces the synthesis of defensive proteinase inhibitor proteins in the treated plants and in nearby plants as well.
The presence of methyl jasmonate in the atmosphere of chambers containing plants from three species of two families, Solanaceae and Fabaceae, results in the accumulation of proteinase inhibitors in leaves of all three species. When sagebrush, Artemesia tridentata , a plant shown to possess methyl jasmonate in leaf surface structures, is incubated in chambers with tomato plants, proteinase inhibitor accumulation is induced in the tomato leaves, demonstrating that interplant communication can occur from leaves of one species of plant to leaves of another species to activate the expression of defensive genes.
Cytokinins in a genic male sterile line of Brassica napus. The failure or inability of an individual to produce functional gametes under a given set of environmental conditions is known as sterility.
Male sterility in plants is generally associated with the lack of production of viable pollen; however its expression can vary Frankel and Galun , Kaul In any event, male sterility is of fundamental importance in the production of hybrid seeds and in breeding programs.
Plant growth substances, both exogenously applied and endogenous, have often been implicated in the regulation of male sterility in several plant species Frankel and Galun , Kaul Cytokinins, gibberellins, auxins and abscisic acid, as well as polyamines, are all known to affect pollen and stamen development in a number of species e.
The objective of this study was to determine a possible relationship between endogenous cytokinins with male sterility in the genic male sterile system in Brassica napus. Thus, an analysis of a number of cytokinins in various organs of the wild type and genic male sterile plants was conducted.
Species-dependent effects of seed predation and ground cover on seedling emergence of old-field forbs. A major goal of plant ecology is to explain spatial variation in a species frequency of occurrence.
Spatial variation in seed predation may contribute to spatial variation in plant frequency by reducing seed supply sufficiently to limit seedling emergence more at one location than another Louda , Anderson Spatial variation in seed predation is well documented e.
Since factors such as dense ground cover may suppress seedling emergence regardless of the amount of seed predation Harper , additional studies are needed to clarify the effect of seed predation on seedling emergence.
Therefore, we examined the effects of both seed predation and ground cover i. Mode of action of natural growth inhibitors in radish hypocotyl elongation -- influence of raphanusanins on auxin-mediated microtubule orientation. Seeds of Raphanus sativus L. After 3 days in darkness at 25oC, 4-mm hypocotyl segments were excised below the hook of the 3 cm long etiolated seedlings.
In other experiments, segments were preincubated for 1 h in small petri dishes containing 1 mM IAA solution, and then raphanusanin B was added to the medium final concentrations 1 or 3 mM. Segment lengths were measured using a microscope with microgauge. All manipulations were carried out under dim green light 3mW m Dynamics of cytoplasmic organelles in the cell cycle of the fission yeast Schizosaccharomyces pombe: Three-dimensional reconstruction from serial sections.
Schizosaccharomyces pombe h90, the homothallic, readily sporing haploid strain, was used. The strain was maintained on malt extract-yeast extract MY agar as described by Tanaka and Kanbe Cells at the exponential phase were spread on a MY plate and further incubated at 30oC for 4 to 6 h before harvesting for microscopy. For the staining of F-actin, cells were washed and suspended in Rh-ph solution Molecular Probes, Inc. Stimulation of root elongation and curvature by calcium.
A scientific paper is a paper that is written for scientists by scientists - or, in case of student writers, for scientists by student scientists. A scientific paper should be precise, structured, and meet the guidelines for scientific works. Find out how to write a convincing scientific paper. Unlike some other written paper types that have a more relaxed approach to formatting, a scientific paper requires a much more thorough approach to the format.
Scientists who often write papers usually use the IMRaD format, which stands for the following:. In this case, you can also include the following sections into your scientific paper:. The way you format your paper should be dictated by the instructions from your professor, by the guidelines of your school, and, in some cases, by your own preferences or view of your future paper. You can get a pretty good idea about writing a scientific paper from a template found online, but your writing will also benefit from a detailed guide into every part of the paper.

Writing the Scientific Paper. W hen you write about scientific topics to specialists in a particular scientific field, we call that scientific writing. (When you write to non-specialists about scientific topics, we call that science writing.) T he scientific paper has developed over the past three centuries into a tool to communicate the results of scientific inquiry. In this paper, I will discuss the issues related to the writing process of a scientific paper. Specifically, I will focus on the best approaches to start a scientific paper, tips for writing each section, and the best revision strategies. Having a list of journal priorities can help you quickly resubmit your paper if your paper is rejected.
