Abstract
Protein kinase plays important roles in plant growth, development, and responses to various biotic and abiotic stresses. Levels of nucleotide diversity, however, have not been investigated to date in natural populations of wild rice. In this study, the diversity of the MAPK5 gene and its characteristics were analyzed in samples of wild rice collected from natural populations in Thailand and Lao PDR, using a re-sequencing DNA technique. For the entire of 514 nucleotides sequence analyzed, non-synonymous, synonymous substitutions, and frame-shift indels were identified in coding sequence of exon1, but not for exon2. For non-coding sequences, indel mutations were present in the sequenced region of the first intron of the MAPK5 gene. These results suggest that alternative splicing transcripts of the MAPK5 gene are potentially generated in response to various environment factors. There was substantial nucleotide variation with a high estimate of nucleotide diversity (π = 0.18113), number of haplotypes (H = 15), and the number of polymorphic sites (S = 319). The Tajima's D value of the MAPK5 gene was 1.673 (p > 0.10), suggesting that the MAPK5 gene of wild rice evolved neutrally. The high level of nucleotide diversity found in natural populations of wild rice may provide populations with the opportunity to adapt to environmental changes in their natural habitats.

期刊介绍:
Gene Reports publishes papers that focus on the regulation, expression, function and evolution of genes in all biological contexts, including all prokaryotic and eukaryotic organisms, as well as viruses. Gene Reports strives to be a very diverse journal and topics in all fields will be considered for publication. Although not limited to the following, some general topics include: DNA Organization, Replication & Evolution -Focus on genomic DNA (chromosomal organization, comparative genomics, DNA replication, DNA repair, mobile DNA, mitochondrial DNA, chloroplast DNA). Expression & Function - Focus on functional RNAs (microRNAs, tRNAs, rRNAs, mRNA splicing, alternative polyadenylation) Regulation - Focus on processes that mediate gene-read out (epigenetics, chromatin, histone code, transcription, translation, protein degradation). Cell Signaling - Focus on mechanisms that control information flow into the nucleus to control gene expression (kinase and phosphatase pathways controlled by extra-cellular ligands, Wnt, Notch, TGFbeta/BMPs, FGFs, IGFs etc.) Profiling of gene expression and genetic variation - Focus on high throughput approaches (e.g., DeepSeq, ChIP-Seq, Affymetrix microarrays, proteomics) that define gene regulatory circuitry, molecular pathways and protein/protein networks. Genetics - Focus on development in model organisms (e.g., mouse, frog, fruit fly, worm), human genetic variation, population genetics, as well as agricultural and veterinary genetics. Molecular Pathology & Regenerative Medicine - Focus on the deregulation of molecular processes in human diseases and mechanisms supporting regeneration of tissues through pluripotent or multipotent stem cells.
