title: Protein accumulation, RNA and soluble amino nitrogen content in developing endosperm of two varieties of Triticum aestivum with high and low protein seed.
abstract: The kinetics of protein accumulation, the variation in RNA, the soluble amino nitrogen content of developing endosperm of two varieties of Triticum aestivum, with high and low protein content in the mature seed, suggest a possible relation between maintenance of the RNA content and the ability to synthesize protein. A sudden halt in protein accumulation is observed as the RNA starts to decrease. The hypothesis is also advanced that maintenance of the RNA content might, in turn, be dependent on the presence, in the endosperm of developing wheat seed, of a certain level of soluble amino nitrogen which could then play the role of limiting factor for protein synthesis.
