Darwin's bark spider shares a spidroin repertoire with Caerostris extrusa but achieves extraordinary silk toughness through gene expression

Nobuaki Kono, Rintaro Ohtoshi, Ali D. Malay, Masaru Mori, Hiroyasu Masunaga, Yuki Yoshida, Hiroyuki Nakamura, Keiji Numata, Kazuharu Arakawa

The paper investigates spidroin sequences and gene expression in Darwin's bark spider and its relative, finding that while spidroin genes are conserved, higher expression in Darwin's bark spider contributes to its tougher silk.

Multicomponent nature underlies the extraordinary mechanical properties of spider dragline silk

Nobuaki Kono, Hiroyuki Nakamura, Masaru Mori, Yuki Yoshida, Rintaro Ohtoshi, Ali D. Malay, Daniel A. Pedrazzoli Moran, Masaru Tomita, Keiji Numata, Kazuharu Arakawa

The paper identifies the multicomponent nature of spider dragline silk and shows that its mechanical properties arise from the combination of specific spidroin and SpiCE proteins.
