The impact of altered gravitation on the fibrillarin quantity and localization in nucleolus of cress root meristem
Cytology and Genetics 2003, v 37, number 4, 40-45
For the first time, under the conditions of altered gravity using fibrillarin antibodies and immunogold microscopy fibrillarin that is one of the most important proteins of rRNA processing was localized. The quantitative study of the density of gold particles in the nucleolus has shown that under clinorotation both the transition zone FC-DFC and the dense fibrillar component were less labeled as compared to the control. Thïèe obtained data allow us to suppose the lowering of the rRNA processing level in the nucleoli under the influence of altered gravity.
