New Pathogen of Wheat, Based on Polyacrylamide Gel Electrophoresis of Cellular Proteins?
نویسندگان
چکیده
The known extant plant pathogenic Ccrynehuc~terirm species were analyzed by polyacrylamide gel electrophoresis of their cellular proteins. The patterns of the protein bands of 13 species and a new corynebacterial wheat pathogen showed seven distinct groups. Five of these groups consisted of only one species each, one group contained four species, and the last group contained the new wheat pathogen and the remaining four species. The pathogens that could not be distinguished by the polyacrylamide gel analysis differed in phenotypic characteristics, including pathogenic specificity. Thus, for these bacteria we propose recognition of the following taxa: Corynehactrrium fnscians (Tilford) Dowson, Corynehacteriurn i1ici.s (Mandel et al.), Corynehac~teriitm tritici (ex Hutchinson) nom. rev., Coiynebac-teriirm iranicirm (ex Scharif) nom. rev., Corynehacterium ra thay i ( Smith) Dow son, Cory ne bac te riir in JIac*c.irmfa ciens sub sp . f r a cc‘u mjiiciens (Hedge s ) Do w s o n , Co ry n e b a c. t e r ii4 in frtr c c‘ 14 r n j k cis n s sub s p . poinsettia e ( S t a rr and Pirone) comb. nov., Corynehacter*izrm flaccirmjciciens subsp. hetae (Keyworth et al.) comb. nov., Corynebacteriiim flaccumnfiiciens subsp. oortii (Saaltink and Maas Geesteranus) comb. nov., Cor~nebactet-ii4in michiganense subsp. michigarrense (Smith) Jensen, Copnebactcriuin michiganense subsp. nebraskense (Schuster et al.) comb. nov., Coi-ynehncterium michiganense subsp. insidiosum (McCulloch) comb. nov., Corynehacteriurn michiganense subsp. sepedcinicum (Spieckermann and Kotthom, comb. nov., and Coi-ynebacterium michigcrnense subsp. tessellariirs subsp. nov., the type strain of which is $train 78181 (= ATCC 33566 = PDDCC 7221).

Grouping of bread wheat cultivars by seed storage proteins. Sonia Kahrizi1, Mohammad Sedghi2* and Omid Sofalian2
To determine seed storage protein banding patterns in some bread wheat cultivars and the similarity of banding patterns among different cultivars, an experiment based on seed storage protein electrophoresis (albumin and globulin) was performed. Water and salt soluble proteins were extracted in sixteen wheat cultivars using polyacrylamide gel electrophoresis and banding pattern was obtained. Stu...

Earthworms possess antioxidant, antibacterial, antitumor, and hemolytic properties. To recognize the molecules responsible for various biological activities of earthworm’s coelomic fluid, a detailed knowledge about its protein contents is required. The aim of this study was to characterize the proteins present within the coelomic fluid of Eisenia foetida earthworm. Polyacrylamide-gel-elec...
متن کاملElectrophoresis and chromatography of wheat proteins: available methods, and procedures for statistical evaluation of the data.
Analysis of gluten proteins from the wheat grain endosperm has long challenged the analytical chemist. Several hundred unique polypeptides are present, many in large polymers. This complexity, plus useful relationships of composition to genotype and quality, encouraged development and application of electrophoresis and chromatography for gluten analysis. We review the methods of polyacrylamide ...

An isoelectric focusing method capable of resolving all groups of storage protein of the wheat seed, including the most basic low molecular weight glutenin (LMWG), was developed. Ultrathin polyacrylamide gels were used after drying and rehydration with 8 M urea, 50 mM DTE and 2.4% carrier ampholytes (pH 4-9). Densitometric scanning of the isoelectric focusing gels permitted a more accurate and ...
