N. Y. The Nitrogen Compounds of Plants and Their Metabolism . 



(Cornell) To (1) recognize, isolate and identify new soluble N compounds 

 that occur as constituents of plants and determine their 

 mode of origin and their function; (2) characterize protein 

 fraction of plants by hydrolysis and quantitative estimation 

 of amino acids so produced; and (3) investigate effects of 

 nutritional and environmental factors on soluble and insoluble 

 N fractions,

N. Y. Studies on the Basal Metabolism Rate of Various Apple 



(Cornell) Varieties . To use the measurement of the basal metabolism 



rate (respiration rate) of apples to build up a store of in- 

 formation that may be used in practical application.

N. C. A Study of the Cytochrome System of Higher Plants in 



Relation to Iron Requirements and Factors Affecting Iron 

 Metabolism. To (1) determine if cytochrome c reductase of 

 plants contains iron as an integral portion of enzyme, and 

 study certain nutritional and other factors that may affect 

 activity of this emzyme system; and (2) purify cytochrome 

 oxidase enzyme of higher plants and determine nutritional 

 and other factors that may affect activity of this enzyme.

N. C. Factors Influencing the Biosynthesis of Carotenoids by 



Yeasts . (1) Identify and characterize carotenoid pigments 

 produced by species of yeast in genera Rhodotorula , Torulopsis, 

 Crypto co ecus and related genera; (2) learn influence of 

 cultural conditions on carotenoid production by yeasts in 

 these genera.

Oreg. Respiration and Intermediary Metabolism in Economic 



Plants . To (1) determine respiratory mechanisms, energy- 

 yielding reactions, and oxidase systems operative in econom- 

 ically important plants; and (2) develop methods for invest- 

 igating practical problems which involve effects of abnormal 

 or adverse conditions upon metabolic reactions of plants.

Pa. Determination of Oxidative Enzyme Systems and Oxidative 



Pathways in Higher Plants . To (1) develop and improve tech- 

 niques for detecting presence and measuring the activity of 

 oxidative enzymes; (2) determine presence and activity of 

 oxidative enzymes in higher plants; and (3) relate presence 

 of oxidative enzymes to metabolic pathways in higher plants.
