Diversity of 7 SL RNA from the signal recognition particle of maize endosperm.

abstract：:Instability of complex mammalian genomic DNA inserts is commonplace in cosmid libraries constructed in conventional multicopy vectors. To develop a means to construct stable libraries, we have developed a low copy number cosmid vector based on the E. coli F factor replicon (Fosmid). We have tested relative stability o...
