Abstract

Previous investigations by Southern hybridization of cDNA with compositional DNA fractions showed that the majority of maize genes are located in a narrow GC range of DNA fragments and that the corresponding gene space was GC-richer than the region of the genome where zein genes are found. Here, we revisited the maize gene space using new data from the maize genome sequencing initiative. We found that the maize gene space itself is formed of two compositional compartments, i.e., a GC-poor and a GC-rich, characterized by a different distribution of Opie and Huck retrotransposons. The GC-rich compartment tends to be richer in GC-rich genes than the GC-poor compartment. However, the gene space compartimentalization of maize is much simpler than that of human.

Limitations of encapsidation of recombinant self-complementary adeno-associated viral genomes in different serotype capsids and their quantitation.

We previously reported that self-complementary adeno-associated virus (scAAV) type 2 genomes of up to 3.3 kb can be successfully encapsidated into AAV2 serotype capsids. Here we report that such oversized AAV2 genomes fail to undergo packaging in other AAV serotype capsids, such as AAV1, AAV3, AAV6, and AAV8, as determined by Southern blot analyses of the vector genomes, although hybridization signals on quantitative DNA slot-blots could still be obtained. Recently, it has been reported that quantitative real-time PCR assays may result in substantial differences in determining titers of scAAV vectors depending on the distance between the primer sets and the terminal hairpin structure in the scAAV genomes. We also observed that the vector titers determined by the standard DNA slot-blot assays were highly dependent on the specific probe being used, with probes hybridizing to the ends of viral genomes being significantly overrepresented compared with the probes hybridizing close to the middle of the viral genomes. These differences among various probes were not observed using Southern blot assays. This overestimation of titer is a systemic error during scAAV genome quantification, regardless of viral genome sequences and capsid serotypes. Furthermore, different serotypes capsid and modification of capsid sequence may affect the ability of packaging intact, full-length AAV genomes. Although the discrepancy is modest with wild-type serotype capsid and short viral genomes, the measured titer could be as much as fivefold different with capsid mutant vectors and large genomes. Thus, based on our data, we suggest that Southern blot analyses should be performed routinely to more accurately determine the titers of recombinant AAV vectors. At the very least, the use of probes/primers hybridizing close to the mutant inverted terminal repeat in scAAV genomes is recommended to avoid possible overestimation of vector titers.

Random segment deletion based on IS31831 and Cre/loxP excision system in Corynebacterium glutamicum.

A simple and random genome deletion method combining insertion sequence (IS) element IS31831 and the Cre/loxP excision system generated 42 Corynebacterium glutamicum mutants (0.2-186 kb). A total of 393.6 kb (11.9% of C. glutamicum R genome) coding for 331 genes was confirmed to be nonessential under standard laboratory conditions. The deletion strains, generated using only two vectors, varied not only in their lengths but also the location of the deletion along the C. glutamicum R genome. By comparing and analyzing the generated deletion strains, identification of nonessential genes, the roles of genes of hitherto unknown function, and gene-gene interactions can be easily and efficiently determined.

Analysis of plasmids encoding extended-spectrum beta-lactamases (ESBLs) from Escherichia coli isolated from non-hospitalised patients in Seville.

Extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli is an emerging pathogen in the community. We investigated the specific types of ESBLs in E. coli isolates from non-hospitalised patients and the plasmids harbouring these ESBLs. Forty-eight consecutive ESBL-producing E. coli were studied. All the isolates were clonally unrelated. ESBLs were characterised by sequencing. Mobility of the undigested plasmids was investigated both by conventional electrophoresis and by pulsed-field gel electrophoresis. Southern restriction fragment length polymorphism (RFLP) experiments were carried out by digesting plasmids with EcoRI and HindIII. CTX-M-14 was the most frequent ESBL (28 isolates), followed by SHV-12 (16 isolates). Plasmids encoding CTX-M-14 appeared homogeneous both in hybridisation profile and mobility. In contrast, plasmids expressing SHV-12 were more varied in size and hybridisation patterns. Our data suggest that a single type or very closely related plasmids harbouring CTX-M-14 are spreading in the community among unrelated E. coli isolates in our area.
