In the present study, we investigated the genetic polymorphisms of 20 novel STR loci and one previously studied locus in the Xibe ethnic group from China, as well as its genetic relationships with neighboring populations. Totally 226 unrelated healthy Xibe individuals were involved in the study. At least 5 alleles were observed for each locus, with the minimum and maximum allelic frequencies of 0...
A full-length cDNA and genomic sequences of a translationally controlled tumor protein (TCTP) gene were isolated from Japanese larch (Larix leptolepis) and designated LaTCTP. The length of the cDNA was 1043bp and contained a 504bp open reading frame that encodes a predicted protein of 167 amino acids, characterized by two signature sequences of the TCTP protein family. Analysis of the LaTCTP gene...
Polar auxin transport provides a developmental signal for cell fate specification during somatic embryogenesis. Some members of the HD-ZIP III transcription factors participate in regulation of auxin transport, but little is known about this regulation in somatic embryogenesis. Here, four HD-ZIP III homologues from Larix leptolepis were identified and designated LaHDZ31, 32, 33 and 34. The occurrence...
While information for single nucleotide polymorphism is accumulating in many organisms, little is known about the magnitude and the occurrence of nucleotide dimorphism or higher order structural polymorphisms (grouped nucleotide polymorphisms or GNPs). To address these questions, we systematically investigated the genetic variations of 996 loci in 96 Arabidopsis accessions. Our data suggest that GNP...
High levels of inter-specific diversity are expected due to genetic isolation, the reproductive or geographical barriers, which lead to the accumulation of nucleotide variation. However, high levels of genetic variation are repeatedly observed even within species, notably at loci of the human major histocompatability complex and of plant resistance genes. Are molecular isolations responsible for the...
