Luminescent termite mounds caused by colonization of the luminescent larvae of the click beetle Pyrearinus termitilluminans (Costa, 1982) are well reported in Cerrado ecosystems (savannas) in central west Brazil (Costa 1982). Although luminous termit

A transcriptional and proteomic survey of Arachnocampa luminosa (Diptera: Keroplatidae) lanterns gives insights into the origin of bioluminescence from the Malpighian tubules in Diptera

Autor: J R, Silva, D T, Amaral, J W, Hastings, T, Wilson, V R, Viviani

Publikováno v: Luminescence : the journal of biological and chemical luminescence. 30(7)

Fungus-gnats of the genus Arachnocampa are unique among bioluminescent insects for displaying blue-green bioluminescence, and are responsible for one of the most beautiful bioluminescence spectacles on the roofs of the Waitomo Caves. Despite morpholo

Molecular phylogeny of Neotropical bioluminescent beetles (Coleoptera: Elateroidea) in southern and central Brazil

Autor: D T, Amaral, F G C, Arnoldi, S P, Rosa, V R, Viviani

Publikováno v: Luminescence : the journal of biological and chemical luminescence. 29(5)

Bioluminescence in beetles is found mainly in the Elateroidea superfamily (Elateridae, Lampyridae and Phengodidae). The Neotropical region accounts for the richest diversity of bioluminescent species in the world with about 500 described species, mos

The origin, diversity, and structure function relationships of insect luciferases

Autor: V. R. Viviani

Publikováno v: Cellular and molecular life sciences : CMLS. 59(11)

Luciferases are the enzymes that catalyze the reactions that produce light in bioluminescence. Whereas the oxidative mechanism which leads to light emission is similar for most luciferases, these enzymes and their substrates are evolutionarily unrela

Bioluminescence color determinants of Phrixothrix railroad-worm luciferases: chimeric luciferases, site-directed mutagenesis of Arg 215 and guanidine effect

Autor: V R, Viviani, Y, Ohmiya

Publikováno v: Photochemistry and photobiology. 72(2)

Chimeric proteins were produced using the green light-emitting luciferase of Phrixothrix vivianii (PxGr: lambda max = 548 nm) and the red light-emitting luciferase of Phrixothrix hirtus (PxRe: lambda max = 623 nm). Constructs containing residues 1-34

Cloning and molecular characterization of the cDNA for the Brazilian larval click-beetle Pyrearinus termitilluminans luciferase

Autor: V R, Viviani, A C, Silva, G L, Perez, R V, Santelli, E J, Bechara, F C, Reinach

Publikováno v: Photochemistry and photobiology. 70(2)

The larval click-beetle Pyrearinus termitilluminans elicits the phenomenon of luminous termite mounds in the central-west region of Brazil. The bioluminescence (BL) spectrum of this larva (lambda max = 534 nm) is one of the most blue-shifted reported
