Glucosylation prevents plant defense activation in phloem-feeding insects.

Osnat Malka, Michael L A E Easson, Christian Paetz, Monika Götz, Michael Reichelt, Beate Stein, Katrin Luck, Aleksa Stanišić, Ksenia Juravel, Diego Santos-Garcia, Lilach L Mondaca, Simon Springate, John Colvin, Stephan Winter, Jonathan Gershenzon, Shai Morin, Daniel G Vassão,

The metabolic adaptations by which phloem-feeding insects counteract plant defense compounds are poorly known. Two-component plant defenses, such as glucosinolates, consist of a glucosylated protoxin that is activated by a glycoside hydrolase upon plant damage. Phloem-feeding herbivores are not generally believed to be negatively impacted by two-component defenses due to ... Read more >>

Tracing animal genomic evolution with the chromosomal-level assembly of the freshwater sponge Ephydatia muelleri

Nathan Kenny, Warren Francis, Ramón Rivera-Vicéns, Ksenia Juravel, Alex de Mendoza, Cristina Díez-Vives, Ryan Lister, Luis Bezares-Calderon, Lauren Grombacher, Maša Roller, Lael Barlow, Sara Camilli, Joseph Ryan, Gert Wörheide, April Hill, Ana Riesgo, Sally Leys,

Abstract The genomes of non-bilaterian metazoans are key to understanding the molecular basis of early animal evolution. However, a full comprehension of how animal-specific traits such as nervous systems arose is hindered by the scarcity and fragmented nature of genomes from key taxa, such as Porifera. Ephydatia muelleri is a ... Read more >>

To B or Not to B: Comparative Genomics Suggests Arsenophonus as a Source of B Vitamins in Whiteflies.

Diego Santos-Garcia, Ksenia Juravel, Shiri Freilich, Einat Zchori-Fein, Amparo Latorre, Andrés Moya, Shai Morin, Francisco J Silva,

Insect lineages feeding on nutritionally restricted diets such as phloem sap, xylem sap, or blood, were able to diversify by acquiring bacterial species that complement lacking nutrients. These bacteria, considered obligate/primary endosymbionts, share a long evolutionary history with their hosts. In some cases, however, these endosymbionts are not able to ... Read more >>
