Abstract:The Drosophila melanogaster was cultured in different temperature conditions and made into slice through the method of modified Carbol Fuchsin staining. The result showed that the distribution of chromosomes in the puff region changed significantly in different temperature conditions, and these regions were relational with the body regulation and gene expression. The changes of regional chromosome under the 15℃ and 27 ℃ temperature conditions were more distinct than under the 19℃ or 23℃. Therefore it was assumed that taking protection measures to disadvantage living of the organism lead to more gene and chromosome changes. And some special genes on puffing of the chromosome region in different temperatures are discussed.
