Dihydrospectinomycin binding to chloroplast ribosomes from antibiotic-sensitive and -resistant strains of Chlamydomonas reinhardtii

Abstract In this paper, we describe the binding of [ 3 H]dihydrospectinomycin to ribosomes isolated from the unicellular green alga, Chlamydomonas reinhardtii . Data presented demonstrate that dihydrospectinomycin binds only to ribosomes susceptible to inhibition by the drug. The specific site for the binding reaction is shown to reside on the small subunit of the 68-S chloroplast ribosome. In addition, binding experiments have been conducted with mutant strains of C. reinhardtii that are phenotypically resistant to spectinomycin. These experiments demonstrate that in a mutant strain with a uniparental pattern of inheritance of spectinomycin resistance, the chloroplast ribosomes no longer bind the antibiotic.

The Art of the Chinese Potter from the Han Dynasty to the End of the Ming

THOUGH this important work, by two of our foremost authorities and connoisseurs of Oriental ceramics, is more concerned with artistic results than with the somewhat uncertain history of scientific progress in porcelain-making, the work is still of considerable interest from the technical point of view. It describes the achievements of the workers at the most important Chinese pottery-centres during the period when fine porcelain, as we know it, was first in process of evolution, and then the orderly progress from the earlier varieties of earthenware and stoneware with which pottery-making begins in every region of the world where it has ever flourished.The Art of the Chinese Potter from the Han Dynasty to the End of the Ming.

Chinese Potters and Porcelain

THIS admirable account of the arts and crafts of the Chinese potters and porcelain-makers during those spacious days of its history when the Celestial Emperors held sway over the larger part of eastern and central Asia is worthy of its great subject; and one could not award it higher praise. The position of Chinese porcelain is so commanding in the history of mans art and craftsmanship, and its example and influence have proved so dominant in Europe, as well as in the Far East, that so comprehensive and reasoned a survey of its development will prove of signal interest to all lovers of fine and noble porcelains; whether their predominant interest is centred in the wares of Asia or in those, of later date, that have been made in Europe. Only an untiring student and scholar, who has charge of a famous collection such as that in the British Museum, and who has worked, there and elsewhere, at the subject in all its aspects, could have produced a volume of such sterling worth. All available sources of information have been utilised-the accounts of early European travellers are drawn upon equally with the latest records of exploration and research - so that we are here presented with as trustworthy an exposition of the subject as we are likely to obtain, and one which might well serve as a model for later workers in similar fields.The Wares of the Ming Dynasty.By R.

Old, Dutch Pottery and Tiles

IT is a pleasure to welcome this competent, scholarly, and interesting account of that renowned pottery-work of the Dutch craftsmen and artists which exercised such a profound and quickening influence on the potters art as it was practised in all the countries of northern and central Europe, especially during the course of the eighteenth century. We already possess, in English, quite a number of small handbooks which treat of this important subject; but here, at last, a volume is presented which may be acclaimed as worthy and complete in its text, and is also so handsomely illustrated as to satisfy every requirement of the collector.Old, Dutch Pottery and Tiles.By Elisabeth Neurdenburg.

The Early Ceramic Wares of China

THIS abridged edition of Mr. Hetheringtons excellent volume on the early pottery and porcelain of the Chinese artist-craftsmen will be welcomed by all those students who were unable to purchase the large and profusely illustrated volume from which this has been condensed. The work of reduction and compression has been so skilfully carried out that there is little or no loss of matter that is absolutely relevant, and the work here presented will serve as an admirable introduction to a complete knowledge of the subject, and to the more important works to which all of us must turn for the completion of the story of Chinese ceramics, in all its fascinating and masterly developments.The Early Ceramic Wares of China.By A.
