Anuretes grandis sp . n . ,

A new species of caligid copepod (Siphonostomatoida), Anuretes grandis sp. n., parasitic on the painted sweetlips [Diagramma pictum (Thunberg)] in Taiwan is described. The new species is distinguished from its congeners by having: (1) free margin of cephalothorax not covering fourth pediger, (2) large genital complex longer than 2/3 of the cephalic shield, (3) no maxillary whip, (4) leg 3 with ...

Pullulomyxa botrytis n. sp.

A brief note was published some years ago by W. T. Morgan of the Lister Institute, London, and the writer (1932) describing the isolation from decayed woody tissues of a micro-organism which decomposes the specific polysaccharides of Shigella dysenteriae, Shiga; Shigella dysenteriae, Flexner Y; Pneumococcus Type II; and the tubercle bacillus. At the time a study of the relationship of this orga...

Quantitative Proteomics Reveals the Defense Response of Wheat against Puccinia striiformis f. sp. tritici

Wheat stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is considered one of the most aggressive diseases to wheat production. In this study, we used an iTRAQ-based approach for the quantitative proteomic comparison of the incompatible Pst race CYR23 in infected and non-infected leaves of the wheat cultivar Suwon11. A total of 3,475 unique proteins were identified from three key...

Diversity resistance to Puccinia striiformis f. sp Tritici in rye chromosome arm 1RS expressed in wheat.

The 1BL.1RS wheat-rye translocation contained in the Russian cultivar Aurora has been the most widespread alien translocation in wheat-breeding programs all over the world. However, following the prevalence of new biotypes of the pathogens, disease-resistance genes in this translocation chromosome have been overcome and consequently they have been eliminated in modern wheat-breeding programs. I...
