资源简介：
Structure of polytene chromosomes of (A) wild-type, (B) DmSetdb110.1a homozygous mutant (DmSetdb110.1a/DmSetdb110.1a), and (C and D) overexpressing DmSETDB1421–1,261 (UAS-DmSetdb1421–1,261 daGal4 homozygotes) of third instar larvae are shown. Polytene chromosomes were stained with orcein. “C” points at the chromocenter and “4” at Chromosome 4. Overexpression of DmSETDB1421–1,261 causes loosening of the chromocenter and constrictions on the arms. The polytene chromosomes of DmSetdb110.1a homozygous mutant do not present any abnormalities.

本数据集展示了三龄幼虫的多线染色体（polytene chromosomes）结构，分别为(A)野生型、(B)DmSetdb110.1a纯合突变体（DmSetdb110.1a/DmSetdb110.1a），以及(C、D)过表达DmSETDB1421–1,261的UAS-DmSetdb1421–1,261; daGal4纯合子。所有多线染色体均经地衣红（orcein）染色。图中标记"C"指向染色中心（chromocenter），标记"4"指向第4号染色体。过表达DmSETDB1421–1,261会引发染色中心松散，并使染色体臂出现缢缩。DmSetdb110.1a纯合突变体的多线染色体未表现出任何异常。(1.9 MB PPT)
