We have previously described a simple method to analyze the chromatin structure of Arabidopsis telomeres independently of that of Interstitial Telomeric Sequences (ITSs). By using this method, we found that, whereas ITSs are heterochromatic, Arabidopsis telomeres exhibit euchromatic features [1]. Some concerns have been recently raised about the accuracy of this procedure [2]. Here, we summarize these concerns and justify our experimental approaches and interpretation of results.
