Rapid appearance of an mRNA correlated with ethylene synthesis encoding a protein ofmolecular weight 35000.

abstract：:The first hours of seed germination are characterized by an increase in the rate of RNA synthesis. Although this change is most easily accounted for by changes in the ribonucleotide pool sizes, we investigated two other aspects of rRNA synthesis which are likely to contribute to the phenomenon. Using isolated radish e...
