A study has been made of the effects of phenylthiourea on the increases in respiration and ascorbic oxidase activity, and on the growth responses which occur in excised sections of tobacco pith when cultured on agar containing indoleacetic acid. At 5—15X104 M, phenylthiourea acts differentially. usually completely inhibiting ascorbic oxidase activity and the growth while permitting a large respiratory increase on auxin. The demonstration that some of the metabolic changes initiated by auxin are not obligatorily coupled to one another nor to the enlargement process may be useful in the study of the mechanism of action of auxin.

The article reports on the rise of Doctors of Philosophy (Ph.D) courses in biosciences in the U.S. Figures reveal that since 1920, over a quarter million earned Ph.D.'s were awarded in the country wherein 46,000 were in biosciences courses including agriculture and health-related fields, resulting to an annual increase of 237 for the 1920s to 2320 for the 1960s. Such growth was attributed to the granting of engineering and education in recent years. Of all the biosciences courses, agriculture and biochemistry are the fastest growing fields at the Ph.D. level.
