    • High-efficient bifunctional catalysts for oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) are critical to the practical application of zinc–air batteries. Herein, a comprehensive investigation on the synergetic contribution of nitrogen (N) and fluorine (F) species in porous carbon for ORR/OER catalyses is firstly conducted. The metal-free N, F co-doped porous carbon (NFPC) possesses appealing catalytic activities in zinc–air batteries and is superior to many other catalysts. Combined with the careful exploration of N and F dopants, seventeen optimized carbon cluster structures with all possible co-doping of N and F species are considered for density functional theory calculations. It can be inferred that the F doping with graphitic and pyridinic N triggers active paramagnetic centers. The co-doping of covalent F and graphitic N especially gives the lowest free energy barrier for both ORR/OER, which could account for the notable performance of NFPC catalysts in zinc–air batteries.

  • A massive expansion of effector genes underlies gall-formation in the wheat pest Mayetiola destructor

    • Gall-forming arthropods are highly specialized herbivores that, in combination with their hosts, produce extended phenotypes with unique morphologies [1]. Many are economically important, and others have improved our understanding of ecology and adaptive radiation [2]. However, the mechanisms that these arthropods use to induce plant galls are poorly understood. We sequenced the genome of the Hessian fly (Mayetiola destructor; Diptera: Cecidomyiidae), a plant parasitic gall midge and a pest of wheat (Triticum spp.), with the aim of identifying genic modifications that contribute to its plant-parasitic lifestyle. Among several adaptive modifications, we discovered an expansive reservoir of potential effector proteins. Nearly 5% of the 20,163 predicted gene models matched putative effector gene transcripts present in the M. destructor larval salivary gland. Another 466 putative effectors were discovered among the genes that have no sequence similarities in other organisms. The largest known arthropod gene family (family SSGP-71) was also discovered within the effector reservoir. SSGP-71 proteins lack sequence homologies to other proteins, but their structures resemble both ubiquitin E3 ligases in plants and E3-ligase-mimicking effectors in plant pathogenic bacteria. SSGP-71 proteins and wheat Skp proteins interact in vivo. Mutations in different SSGP-71 genes avoid the effector-triggered immunity that is directed by the wheat resistance genes H6 and H9. Results point to effectors as the agents responsible for arthropod-induced plant gall formation.
