Abstract
In the plant-parasitic nematode Meloidogyne arenaria, isolated rDNA repeats show length heterogeneity, and are unusual in that they contain putative 5S ribosomal RNA pseudogenes [Vahidi et al., J. Mol. Evol. 27 (1988) 222-227]. Potentially functional 5S rRNA-encoding genes can also be identified in various rDNA repeats, which appear to be tandemly organized in the genome.
摘要
在植物寄生线虫南方根结线虫中，分离出的核糖体DNA重复序列显示出长度异质性，其不同寻常之处在于它们含有推定的5S核糖体RNA假基因[瓦希迪等人，《分子进化杂志》27(1988)222 - 227]。在各种核糖体DNA重复序列中也能鉴定出潜在的功能性5S rRNA编码基因，这些基因在基因组中似乎是串联排列的。
