Rapid Changes in Protein Phosphorylation Associated with Light-Induced Gravity Perception In Corn Roots 1
AUTOR(ES)
McFadden, J. J.
RESUMO
The effect of light and calcium depletion on in vivo protein phosphorylation was tested using dark-grown roots of Merit corn. Light caused rapid and specific promotion of phosphorylation of three polypeptides. Pretreatment of roots with ethylene glycol bis N,N,N′, N′ tetraacetic acid and A23187 prevented light-induced changes in protein phosphorylation. We postulate that these changes in protein phosphorylation are involved in the light-induced gravity response.
