Life History and Laboratory Rearing of \u3ci\u3eGerris Argenticollis\u3c/i\u3e (Hemiptera: Gerridae) with Descriptions of Immature Stages

The life history of Gerris argenticollis was investigated in Jackson County, Illinois, March-June 1986, and the immature stages were described. The water strider also was reared from egg to adult under laboratory conditions. This univoltine species overwintered as adults that became active in early March, appearing on a temporary woodland pond after the air temperature exceeded 12°C. Seasonal occurrence of the adults and immatures is discussed. Adults were last observed in mid-June. Feeding records are given. G. argenticollis was reared on Drosophila melanogaster adults under a 10L: 14D photoperiod (ca. 2800 lux) at ca. 21°C. The incubation period averaged 12.5 days. The average durations of the five nymphal stadia were 9.0, 7.6, 8.0, 9.2, and 12.0 days. The total developmental period averaged 58.3 days

Binding of Vac14 to neuronal nitric oxide synthase: Characterisation of a new internal PDZ-recognition motif

AbstractPDZ domains mediate protein interactions primarily through either classical recognition of carboxyl-terminal motifs or PDZ/PDZ domain associations. Several studies have also described internal modes of PDZ recognition, most of which depend on β-finger structures. Here, we describe a novel interaction between the PDZ domain of nNOS and Vac14, the activator of the PtdIns(3)P 5-kinase PIKfyve. Binding assays using various Vac14 deletion constructs revealed a β-finger independent interaction that is based on a novel internal motif. Mutational analyses reveal essential residues within the motif allowing us to define a new type of PDZ domain interaction
