From: tRNA-Cys gene clusters exhibit high variability in Arabidopsis thaliana
Mini clusters of tRNA-Cys genes. (A) A cluster of divergently transcribed tRNA-Cys genes on chromosome 2 conserved in all A. thaliana accessions analyzed in this study. (B) A cluster of tandemly repeated tRNA-Cys genes overlapping in antisense orientation the second intron of the gene encoding ubiquitin domain-containing protein on chromosome 1. (C) Schematic alignment of the chromosome 1 tRNA-Cys cluster region from various A. thaliana accessions. (D) Experimental evaluation of the observed clusters’ size variation using PCR amplification on genomic DNA (see also Supplementary Figure S8)
