Transcriptomic, proteomic and biochemical comparison of luminescent and non-luminescent Keroplatinae larvae (Diptera: Keroplatidae). [PDF]

open access: yesInsect Mol Biol
Transcriptomic and proteomic comparison of luminescent O. fultoni and non‐luminescent Neoditomyia sp show that the substrate binding fraction (SBF) has a similar abundance of hexamerins and the presence of flavin‐dependent reductases. In addition to the high content of keroplatin, SBF also contains considerable amounts of riboflavin and displays ...
