2. Supplementary Figures and Tables from Convergent evolution of elaborate nests as structural defences in birds

Author

Street, Sally E., Jaques, Robert, and De Silva, Thilina N.

Abstract

The pendent nests of some weaverbird and icterid species are among the most complex structures built by any animal, but why they have evolved remains to be explained. The precarious attachments and extended entrance tunnels characteristic of these nests are widely speculated to act as structural defences against invasion by nest predators, particularly tree-climbing snakes, but this hypothesis has yet to be systematically tested. We use phylogenetic comparative methods to investigate the relationship between nest structure and developmental period length, a proxy for offspring mortality, in weaverbirds (Ploceidae) and icterids (Icteridae), two bird families in which highly elaborate pendent nests have independently evolved. We find that more elaborate nests, particularly those with entrance tunnels, are associated with longer developmental periods in both families. This finding is robust to potentially confounding effects of body mass, phylogenetic relationships, nest location and latitude. Our results are consistent with the hypothesis that elaborate nest structures in birds can function as structural defences, resulting in lower offspring mortality and slower development. More generally, our findings suggest that constructing complex, protective structures may buffer against environmental hazards, reducing extrinsic mortality and contributing to the evolution of slower life histories in diverse animal lineages, even humans.

Abstract

Peanut grains are very susceptible to aflatoxin contamination. Aflatoxins are toxic metabolites produced by Aspergillus flavus, A. nomius and A. parasiticus. The aflatoxin B1 is most frequently found in peanuts, posing a high toxicological risk due to its carcinogenic, teratogenic and mutagenic properties. Alternative methods to fungicides can be used to protect grains. GRAS (Generally Regarded As Safe) substances can be an interesting option to avoid contamination, specially glycerol. In the present work, the ability of glycerol films to prevent aflatoxin production by A. parasiticus in peanuts was evaluated. Glycerol was established in two different ways: by immersion and aspersion. Aspersion was more efficient in reducing aflatoxin production (86.3%) than was the immersion process (66.9%) (P < 0.05). At the same time, a progressive reduction in A. parasiticus colony diameters was observed (from 38.6 ± 0.9 to 34.4 ± 1.7 mm) when the fungus was grown on GYEP medium supplemented with glycerol (0 to 5%). However, varying concentrations did not influence the production of spores, colonies, conidiophores or spore condition. Peanuts coated with 5% glycerol (by immersion or aspersion) had improved characteristics, with a cleaner and more shiny appearance, which can make the resulting product more acceptable to the population. In conclusion, the reduction of aflatoxin production in peanut grains with glycerol, particularly by aspersion, was satisfactory, and this GRAS substance shows promising potential to be used to prevent mycotoxin contamination in grains.Key words: GRAS substances. Mycotoxin. Grain storage. Food preservation. RESUMO O amendoim é muito suscetível à contaminação por aflatoxinas, que são metabólitos tóxicos produzidos por Aspergillus flavus, A. parasiticus e A. nomius. A aflatoxina B1 é a mais frequentemente encontrada nos amendoins e apresenta risco toxicológico devido às suas propriedades carcinogênicas, teratogênicas e mutagênicas. Entre os métodos de prevenção da contaminação, o uso de substâncias GRAS (substâncias geralmente consideradas seguras) pode apresentar grande potencial de exploração, especialmente o glicerol. No presente trabalho, foi avaliada a capacidade de filmes de glicerol para o controle da produção de aflatoxinas em amendoins. O glicerol foi inoculado por imersão ou aspersão, sendo a aspersão mais eficiente na redução da produção de aflatoxina (86,3%) que a imersão (66,9%) (P < 0,05). Ao mesmo tempo, foi observada uma redução nos diâmetros das colônias de A. parasiticus (38,6 ± 0,9 para 34,4 ± 1,7 mm) quando cultivado em meio GYEP suplementado com glicerol (0 a 5%). Apesar disto, diferentes concentrações não influenciaram a produção ou morfologia dos esporos e conidióforos. Amendoins revestidos com 5% de glicerol apresentaram características interessantes, tais com: maior brilho e coloração mais intensa, o que pode tornar o produto mais atraente para o consumidor. Em conclusão, a redução da produção de aflatoxinas em amendoim pelo glicerol, principalmente por aspersão foi satisfatória. Sendo assim, esta substância apresenta um potencial promissor para utilização para a prevenção da contaminação do amendoim por aflatoxinas.Palavras-chave: Substâncias GRAS. Micotoxinas.

Abstract

This is a pre-copyedited, author-produced version of an article accepted for publication in Carcinogenesis following peer review. The version of record Banach, M., Edholm, E.-S., Gonzalez, X., Benraiss, A. & Robert, J. (2019). Impacts of the MHC class I-like XNC10 and innate-like T cells on tumor tolerance and rejection in the amphibian Xenopus. Carcinogenesis, 40(7), 924–935. is available online at: https://doi.org/10.1093/carcin/bgz100 The conditions that lead to antitumor or protumor functions of natural killer T (NKT) cells against mammalian tumors are only partially understood. Therefore, insights into the evolutionary conservation of NKT and their analogs—innate-like T (iT) cells—may reveal factors that contribute to tumor eradication. As such, we investigated the amphibian Xenopus laevis iT cells and interacting MHC class I-like (XNC or mhc1b.L) genes against ff-2 thymic lymphoid tumors. Upon ff-2 intraperitoneal transplantation into syngeneic tadpoles, two iT cell subsets iVα6 and iVα22, characterized by an invariant T-cell receptor α chain rearrangement (Vα6-Jα1.43 and Vα22-Jα1.32 respectively), were recruited to the peritoneum, concomitant with a decreased level of these transcripts in the spleen and thymus. To address the hypothesize that different iT cell subsets have distinct, possibly opposing, roles upon ff-2 tumor challenge, we determined whether ff-2 tumor growth could be manipulated by impairing Vα6 iT cells or by deleting their restricting element, the XNC gene, XNC10 (mhc1b10.1.L), on ff-2 tumors. Accordingly, the in vivo depletion of Vα6 iT cells using XNC10-tetramers enhanced tumor growth, indicating Vα6 iT cell-mediated antitumor activities. However, XNC10-deficient transgenic tadpoles that also lack Vα6 iT cells were resistant to ff-2 tumors, uncovering a potential new function of XNC10 besides Vα6 iT cell development. Furthermore, the CRISPR/Cas9-mediated knockout of XNC10 in ff-2 tumors broke the immune tolerance. Together, our findings demonstrate the relevance of XNC10/iT cell axis in controlling Xenopus tumor tolerance or rejection.
