| identification and comparison of candidate olfactory genes in the olfactory and non-olfactory organs of elm pest ambrostoma quadriimpressum (coleoptera: chrysomelidae) based on transcriptome analysis. | the leaf beetle ambrostoma quadriimpressum (coleoptera: chrysomelidae) is a predominant forest pest that causes substantial damage to the lumber industry and city management. however, no effective and environmentally friendly chemical method has been discovered to control this pest. until recently, the molecular basis of the olfactory system in a. quadriimpressum was completely unknown. in this study, antennae and leg transcriptomes were analyzed and compared using deep sequencing data to identi ... | 2016 | 26800515 |
| selectivity and ligand-based molecular modeling of an odorant-binding protein from the leaf beetle ambrostoma quadriimpressum (coleoptera: chrysomelidae) in relation to habitat-related volatiles. | in this study, the most abundant and antenna-specific odorant-binding protein (obp) of the elm pest a. quadriimpressum, aquaobp4, was expressed and purified. the selectivity of aquaobp4 was investigated by screening against a panel of 40 habitat-relevant compounds. based on the obtained results, a homologous model of aquaobp4 was established. this model indicated that aquaobp4 is highly homologous to dmelobp lush and includes two main binding sites. a docking analysis showed that four of five ac ... | 2017 | 29133810 |
| a new phenylethyl alkyl amide from the ambrostoma quadriimpressum motschulsky. | a new phenylethyl alkyl amide, (10r)-10-hydroxy-n-phenethyloctadecanamide (1), was isolated from the beetle ambrostoma quadriimpressum motschulsky. the structure of the amide was determined by nmr and ms. the absolute configuration of compound 1 was confirmed by an asymmetric total synthesis, which was started from l-glutamic acid. the construction of the aliphatic chain was accomplished by the selective protection of the hydroxy groups and two-time implementation of the wittig olefination react ... | 2011 | 22043245 |
