Embryos isolated from grain of rye Lovaszpatonai with percentage viability of 95, 64, 48, 15 or 0% were used to study the causes of failure in protein synthesis during loss of viability. Reduced rates of germination and protein synthesis in vivo were characteristic symptoms of embryo ageing. Biochemical studies with poly U-dependent, cell-free systems indicated that enzymic binding of aminoacyl-tRNA to ribosomes (transferase 1 activity) was reduced concomitant with loss of viability.
