Genetical and biochemical studies of yellow lethal larvae in the silkworm

(1). On the nature of pterin obtained from the yellow lethal strain

Abstract

In a previous paper, M. Tsujita, one of the authors, has reported on the allelic relation of yellow lethal to lemon in the silkworm, as well as on the maternal inheritance of yellow lethal. Subsequently, we are now carrying on genetical and biochemical studies of the yellow lethal larvae. As the first step, pterins and other fluorescence compounds contained in the yellow lethal larvae were investigated. This paper deals with this experimental results.
