abstract：:Oat (Avena sativa L.) seeds harvested at 2-day intervals from anthesis to maturity were tested for their ability to incorporate [(35)S]sulfate into protein. Incorporation of [(35)S]sulfate into TCA-insoluble material began 2 to 4 days postanthesis (DPA), reached a peak 14 to 16 DPA, and was barely detectable by 24 DPA...
