A literal elytral rainbow: tunable structural colors using single diamond biophotonic crystals in Pachyrrhynchus congestus weevils

Wilts, Bodo D. ; Saranathan, Vinodkumar

In: Small, 2018, vol. 14, no. 46, p. 1802328

The brilliant colors of many insects arise from the interference of incident light with complex nanostructured biomaterials that are present in their cuticle. Here, the rainbow‐colored spots on the elytra of a snout weevil, Pachyrrhynchus congestus pavonius (Coleoptera: Curculionidae), are investigated using synchrotron small‐angle X‐ray scattering, scanning electron microscopy,...

A meiotic XPF-ERCC1-like complex recognizes joint molecule recombination intermediates to promote crossover formation

De Muyt, Arnaud ; Pyatnitskaya, Alexandra ; Andréani, Jessica ; Ranjha, Lepakshi ; Laureau, Raphaëlle ; Fernandez-Vega, Ambra ; Holoch, Daniel ; Girard, Elodie ; Govin, Jérome ; Margueron, Raphaël ; Couté, Yohann ; Cejka, Petr ; Guérois, Raphaël ; Borde, Valérie

In: Genes and development, 2018, vol. 32, no. 3-4, p. 283-296

Meiotic crossover formation requires the stabilization of early recombination intermediates by a set of proteins and occurs within the environment of the chromosome axis, a structure important for the regulation of meiotic recombination events. The molecular mechanisms underlying and connecting crossover recombination and axis localization are elusive. Here, we identified the ZZS...
