Regulation of heavy metals accumulated by Acorus calamus L. in constructed wetland through different nitrogen forms.

Improving accumulation of heavy metals (HMs) by plants is an important pathway for constructed wetland (CW) to alleviate the environmental risks caused by their release. This study aims to regulate HMs (Cr, Ni, Cu, Zn, and Cd) accumulated by Acorus calamus L. in the sandy substrate CW with different nitrogen forms, including ammonia (NH), nitrate (NO‾), and NH/NO‾ (1:1) in synthetic tailwaters.

Wolbachia localization during Laodelphax striatellus embryogenesis.

Wolbachia are intracellular bacteria carried by thousands of arthropod species. The success of Wolbachia is due to efficient vertical transmission by the host maternal germline. Wolbachia's behavior during host oogenesis is well characterized, although their behavior during embryogenesis is unclear.

Vertical Transmission of Is Associated With Host Vitellogenin in .

in host germ lines are essential for their vertical transmission to the next generation. It is unclear how the regulation of host oocyte development influences location and the mechanistic basis of transmission. Here, we investigated whether vitellogenin influences transmission in .
