Preparation of intact plant mitochondria

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1972
Abstract Mitochondria from mung bean hypocotyls and potato tubers have been separated from contaminating organelles and membrane fragments on discontinuous sucrose gradients. After removal from the centrifuge tubes only intact mitochondria survive dilution to 0.3 M sucrose.

Sample preparation for plant metabolomics

Phytochemical Analysis, 2009
AbstractSample preparation in plant metabolomics is a fundamental and critical step with important consequences for the accuracy of results. Depending on the analytical tools and the metabolites of interest, sample preparation has to be decided. However, the various methods reported in the literature have many steps in common and consequently the ...

THE OXIDATION OF ETHANOLAMINE BY PLANT TISSUE PREPARATIONS

Canadian Journal of Biochemistry, 1966
Ethanolamine-1,2-14C was oxidized to14CO2by tissue slices from carrots, onions, beets, turnips, parsnips, radishes, pea seedlings, wheat seedlings, corn seedlings, and oat seedlings. A monoamine oxidase from spinach, beet, and bean leaves which catalyzed the oxidation of ethanolamine to glycolaldehyde was partially characterized.

Survey of noise in coal preparation plants

The Journal of the Acoustical Society of America, 2007
In response to the continuing problem of noise induced hearing loss (NIHL) among mine workers, the National Institute for Occupational Safety and Health (NIOSH) has conducted numerous noise surveys in coal preparation plants. The research, consisting of worker dose monitoring, task observations, and equipment noise profiling, was completed in eight ...

Site preparation, soil management, and planting.

2013
Abstract This chapter focuses on the importance of the treatment and management of the site and soil before planting in improving the growth and productivity of blackberries. Some factors that need to be considered prior to blackberry cultivation, such as the soil physical, chemical and biological properties, soil quality and field layout, are ...

Protoplasts: Preparation from Higher Plants

Science, 1966
Protoplasts can be readily prepared from higher-plant tissue with a concentrated Myrothecium cellulase preparation. An ionic osmoticum produced a higher yield and more viable protoplasts than did the nonionic mannitol osmoticum. Addition of polyuronidases or of ethylenediaminetetra-acetate did not increase the yield.

Sample Preparation Focusing on Plant Omics

2019
Because of strong impact of omics in many fields, and the complexity of the samples when focusing on areas such as genomics, (metallo)proteomics, metabolomics, among others, it is easy to rationalize the great importance that sample preparation has for achieving reliable results, mainly considering plant science.

Preparation of transgenic plants

1970
Selectable marker genes are used in nearly all transformation procedures. They are required for efficient generation of transgenic plants, but serve no purpose once plants have been obtained that are homozygous for the transgene. On the contrary, their continued presence can pose technological problems, because it precludes retransformation (gene ...

THE ELECTROPHORETIC ANALYSIS OF PLANT VIRUS PREPARATIONS

Canadian Journal of Biochemistry and Physiology, 1959
Zone electrophoresis in agar gel has been used for separating tobacco mosaic virus and potato virus X from crude plant extracts and reaction mixtures. The viruses were located within the gel by autoradiographic, serological, and protein-staining methods.
