Abstract

The major 5S rRNA gene repeat of the marsupial frog, Gastrotheca riobambae, is 1052 bp in length. It contains a 5S rRNA gene similar to the Xenopus laevis somatic gene, two spacer regions, and a pseudogene. The G. riobambae haploid genome contains about 500 copies of this predominant repeat. This relatively low number of 5S rRNA genes is associated with a limited amplification of the 18S, 5.8S and 28S rRNA genes in oocytes and with a slow rate of early development.

摘要

袋蛙（Gastrotheca riobambae）的主要5S rRNA基因重复序列长度为1052 bp。它包含一个与非洲爪蟾体细胞基因相似的5S rRNA基因、两个间隔区和一个假基因。袋蛙的单倍体基因组包含约500个这种主要重复序列的拷贝。5S rRNA基因数量相对较少与卵母细胞中18S、5.8S和28S rRNA基因的有限扩增以及早期发育速度缓慢有关。
