Protéines nucléaires basiques et croissance chez l'hypocotyle de Lupinus albus L.

Nuclear basic proteins and growth in hypocotyls of Lupinus albus L. seedlings

Characteristic changes in the basic nuclear proteins/DNA ratio may be observed during the residual growth of lupine seedling hypocotyls.

This ratio decreases at the very beginning of hypocotyl growth (growth initiation) but increases during its active growth. A second decline coincides with gemmule development. No further increase in the relative amount of basic proteins can be observed during the diminishing elongation before growth ceases.

These results may be related to the known regulating action of the gemmule on hypocotyl growth.
