Higher Order Structure of the Condensed Chromatin in Interphase Nuclei of Wheat

Xiang Wei, Jiao Ming-da and Hao Shui   

Abstract: Using conventional transmission electron microscopy, higher order structure of the condensed chromatin in interphase nuclei of root tip meristems of Triticum aestivum L. was investigated. Chromonemata at different levels with 20–25 nm, 50 nm and 110–120 nm in diameter were observed. It has been found that the chromonema of 110–120 nm in diameter was organized from chromonema of 50 nm, and the latter was organized in turn from chromonema of 20–25 nm. The manner of condensation of higher order structure within these three levels was discussed in this paper.

Key words: Triticum aestivum, Condensed chromatin, Higher order structure
