Expression of d1- and d3-cyclin genes in pea (Pisum sativum L.) root meristem under clinorotation

Cytology and Genetics 2006, v 40, number 2, 34-38

Using in situ hybridization the d1- and d3-cyclin gene expression has been shown in pea (Pisum sativum L.) root meristem cells under slow horizontal clinorotation and in the stationary conditions. The clinorotation effect on expression of these genes during pea root germination was detected. The delay of degradation of cyclin subunits is the cause of G1-phase prolongation under clinorotation leading to delay of pea seed germination. This may explain the increase of cell cycle duration.
