Palaearctic seed beetle (Coleoptera, Chrysomelidae, Bruchinae) new to North America, arrival, distribution, and autecology.

First North American records are presented for Frölich, 1799 (Coleoptera, Chrysomelidae, Bruchinae), as confirmed by morphology from multiple sites in Canada: British Columbia, Ontario, and Québec. Diagnostic information is presented for in North America. This insect is expected to reduce plant reproductive output in infested L.

Calnexin is involved in apoptosis induced by endoplasmic reticulum stress in the fission yeast.

Stress conditions affecting the functions of the endoplasmic reticulum (ER) cause the accumulation of unfolded proteins. ER stress is counteracted by the unfolded-protein response (UPR). However, under prolonged stress the UPR initiates a proapoptotic response.
