Novel nuclear intron-spanning primers for Arecaceae evolutionary biology.
نویسندگان
چکیده
In this study, 96 nuclear 'conserved intron-scanning primers' were screened across subfamilies the Arecaceae (palms) for potential use in research focused on palm evolutionary biology. Primers were evaluated based on their ability to amplify single polymerase chain reaction products in Arecaceae, the clarity of sequencing reads, and the interspecific variability observed. Ultimately, the results suggest that: (i) seven of the loci are likely to be suitable when comparing non-Arecaceae outgroups and Arecaceae ingroups; (ii) seven loci may be of use when comparing subfamilies of Arecaceae; and (iii) four of the loci may be of use when comparing closely related genera.

Novel primers for the amplification of nuclear DNA introns in the entomopathogenic nematode Heterorhabditis bacteriophora and their cross-amplification in seven other Heterorhabditis species.
We describe 24 novel primers that amplify intron regions in housekeeping and structural genes of Heterorhabditis bacteriophora. The cross-amplification potential of these primers in seven other Heterorhabditis species was determined. The results obtained showed interspecific nucleotide, length and splice site variability in the sequenced introns and for one gene, an intron gain was observed. Th...
متن کاملExon-primed, intron-crossing (EPIC) loci for five nuclear genes in deep-sea protobranch bivalves: primer design, PCR protocols and locus utility.
We describe PCR primers and amplification protocols developed to obtain introns from conserved nuclear genes in deep-sea protobranch bivalves. Because almost no sequence data for protobranchs are publically available, mollusk and other protostome sequences from GenBank were used to design degenerate primers, making these loci potentially useful in other invertebrate taxa. Amplification and sequ...

UNLABELLED PREMISE OF THE STUDY Novel nuclear exon-primed intron-crossing (EPIC) markers were developed to increase phylogenetic resolution among recently diverged lineages in the frankincense and myrrh family, Burseraceae, using Citrus, Arabidopsis, and Oryza genome resources. • METHODS AND RESULTS Primer pairs for 48 nuclear introns were developed using the genome resource IntrEST and we...
متن کاملPolymorphism across an exon-intron boundary in an avian Mhc class II B gene.
Twenty-three sequence haplotypes spanning the boundary of the second exon and intron of a red-winged blackbird Mhc class II B gene, Agph-DAB1, are presented. The polymorphism of the exon segment is distributed in two divergent allelic lineages which appear to be maintained by balancing selection. The silent nucleotide diversity of the exon (pi = 0.101) is more than five times that of the intron...
متن کاملContrasting population structure from nuclear intron sequences and mtDNA of humpback whales.
Powerful analyses of population structure require information from multiple genetic loci. To help develop a molecular toolbox for obtaining this information, we have designed universal oligonucleotide primers that span conserved intron-exon junctions in a wide variety of animal phyla. We test the utility of exon-primed, intron-crossing amplifications by analyzing the variability of actin intron...
