Protein synthesis in germinating pollen of Petunia: role of proline

Pollen of Petunia hybrida was germinated in artificial medium. At the beginning of the incubation, a large amount of proline, which comprises about half of the total free amino acid pool, was released into the me...

Identification of estrogen-inducible growth factors (estromedins) for rat and human mammary tumor cells in culture

The role of polypeptide growth factors (estromedins) as mediators of estrogen-responsive mammary tumor growth is studied in this report. Three possible new mechanisms were investigated that include endocrine, ...

Proline metabolism in pollen: degradation of proline during germination and early tube growth

Proline degradation inPetunia pollen germinated in vitro was studied in cultures supplemented with [¹⁴C]proline labeled at different positions. Despite its abundance in the cell, this amino acid is only a minor s...
