The lack of correlation between the rate of rRNA transport from nucleoli into cytoplasm and the duration of G1 and G2 phases in root meristem cells.

Abstract:

:In root meristems of 3 species (Secale cereale L., Vicia faba L. subsp. minor, Allium cepa L.) the durations of cell cycles and their phases were calculated using 3H-thymidine labelling. In the above species and in Helianthus annuus L. (parameters of the cell cycle determined earlier) the G1 and G2 phase durations were different: G1 + 1/2 M from 3 h to 6.1 h, G2 + 1/2 M from 1.1. h to 8.3 h, depending on the species. The rate of rRNA transport from nucleoli into cytoplasm during recovery after cold treatment was calculated from our data presented earlier. The results indicate that in 4 species studied there is no correlation (at P = 0.05) between the rate of rRNA transport and the duration of G1 and G2 phases.
