A new species of genus Leluthia Cameron (Hymenoptera: Braconidae), L. chinensis Li & van Achterberg, sp. nov. is described and illustrated. It was reared from Agrilus sp. (Coleoptera: Buprestidae), a twig-boring pest of Caragana korshinskii Kom. (Leguminosae) in Inner Mongolia Autonomous Region, NW China. A key to the East Palaearctic species of the genus Leluthia is provided.

Copper(II) oxide nanoparticles (CuO NPs) are used in different industries and agriculture, thus leading to their release to the environment, which raises concerns about their ecotoxicity and biosafety. The main toxicity mechanism of nanometals is oxidative stress as a result of the formation of reactive oxygen species caused by metal ions released from nanoparticles. Bacterial biofilms are more resistant to physical and chemical factors than are planktonic cells due to the extracellular polymeric matrix (EPM), which performs a protective function.

Norway maple and sycamore belong to the Acer genus and produce desiccation-tolerant and desiccation-sensitive seeds, respectively. We investigated the seed germination process at the imbibed and germinated stages using metabolomic and proteomic approaches to determine why sycamore seeds germinate earlier and are more successful at establishing seedlings than Norway maple seeds under controlled conditions. Embryonic axes and embryonic axes with protruded radicles were analyzed at the imbibed and germinated stages, respectively.

Two Gram-stain-negative, motile, non-spore-forming, aerobic or facultative anaerobic and short rod-shaped bacterial strains, 25B02-3 and BH-R2-4, were isolated from surface seawater collected from the Bering Sea and Chukchi Sea, respectively. The 16S rRNA gene sequences of the two strains were identical. The phylogenetic analysis of the 16S rRNA gene sequences indicated that they were related to the genus and shared 99.

Five aerobic, Gram-stain-negative bacterial strains, designated as C3-2-a3, B3-2-R+30, C3-2-a4, C3-2-M3 and C3-2-M8, were isolated from the coastal soil of LungmuCo Lake in the Tibet Autonomous Region, PR China. Phylogenetic analyses based on 16S rRNA genes and genomes indicated that these isolates belonged to the genus and showed a high similarity to LNNU 24178 (99.01%), RD2P54 (98.

The publication of several high-quality genomes has contributed greatly to clarifying the evolution of citrus. However, due to their complex genetic backgrounds, the origins and evolution of many citrus species remain unclear. We assembled de novo the 294-Mbp chromosome-level genome of a more than 200-year-old primitive papeda (DYC002).
