The following P{hsp26-pt-T} insertions were chosen by Sally Elgin to provide position-effect variegation patterns of miniwhite characteristic of centric, telomeric, Y and fourth chromosome heterochromatin.
P{hsp26-pt-T} carries Hsp26 regulatory sequences driving expression of a plant cDNA sequence and Hsp70 regulatory sequences driving expression of miniwhite.
