  The genetic relationship of 20 Carnivora species in Thailand was determined based on sequence analysis of the Internal Transcribed Spacer (ITS) region of ribosomal DNA. Aligned sequences of the complete ITS region obtained from the 20 taxa and two primate outgroups resulted in 890 characters with 710 variable sites. Genetic distances and a phylogenetic tree were constructed from comparisons of ITS sequences using the Neighborjoining method. The dendogram demonstrates that the 22 taxa can be clearly grouped in six clusters: Mustelidae, Ursidae, Canidae, Felidae, Viveridae and Hylobatidae. Of these clusters, the 20 Canivora species are clustered together and the superfamilies Caniformia and Feliformia can be separated apart, whereas the outgroup Hylobatidae is segregated from the canivora. In superfamilies Caniformia, the families Mustelidae, Ursidae and Canidae are clustered together. In superfamilies Feliformia, the family Felidae is clustered with Viverridae. The phylogenetic tree of Viverridae species does not completely match the classification based on morphological characters. The Paradoxurinae, Arctictis binturong was grouped into the Viverrinae while the other Paradoxurinae, Paradoxurus hermaphroditus, Paguma larvata and Arctogalidia trivirgata are clustered together.

  Nepenthes gracilis Korth. is a member of carnivorous plants in family Nepenthaceae. The plants have beautiful and economically important pitchers. It is interesting to study the protein(s) correlated with the pitcher. Crude proteins were extracted from leaf, leaf with developing pitcher and developed pitcher of the same plant and analyzed by Sodium Dodecyl Sulfate Polyacrylamide Gel Electrophoresis (SDS-PAGE). Two protein bands with molecular weights of 42.7 and 38 kDa were obtained from young leaf and leaf with developing pitcher, respectively. The 42.7 kDa protein was identified as phosphoglycerate kinase (PGK) by Liquid Chromatography Mass Spectrometry (LC-MS/MS), but the 38 kDa band is an unknown protein. Both proteins were differentially expressed in each developing stage of the pitcher, thus may be powerful candidates play role in development pathway of leaf and pitcher.
