  eLife Assessment

  Insects can act as vectors of plant diseases, hence the study of insect-pathogen interactions is relevant for agriculture. This important study identifies in Diaphorina citri a dopamine receptor responsive to 'Candidatus Liberibacter asiaticus' infection, demonstrate direct regulation of this receptor by a microRNA, and integrate dopamine signaling into an established insect reproductive hormone framework. Multiple complementary experimental approaches convincingly support the findings, but key conclusions rely on correlative data and the mechanistic evidence for the proposed linear signaling cascade is incomplete. This work will be of interest for insect physiology and vector-pathogen biology, and more broadly for citrus agriculture.

  eLife Assessment

  This study provides an important assessment of how body size influences the occurrence of macro-organisms in urban areas across the globe. Size in most plants, but only some animal families, was positively associated with urban tolerance. The data set is impressive, but the evidence for broad-scale conclusions is incomplete due to methodological issues that need to be resolved.

  eLife Assessment

  This study provides important evidence that myristate, a fatty acid commonly present in soil environments, is taken up by arbuscular mycorrhizal fungi during symbiosis with a plant host. The evidence presented is solid, with multiple experimental approaches including stable isotope tracing, transcriptional analysis, and physiological measurements across different plant species and phosphorus conditions. However, the main claims are only partially supported.

Cardenolide toxin diversity impacts monarch butterfly growth and sequestration

  eLife Assessment

  This important study shows that different forms and mixtures of cardenolide toxins in tropical milkweed, especially nitrogen- and sulfur-containing types, change how monarch caterpillars eat, grow, and store these chemicals under laboratory conditions. It provides solid evidence to demonstrate that chemical diversity within a single group of plant toxins (cardenolides) can have combined effects on even highly specialized herbivores that are different from what one would expect from each toxin alone. However, as all experiments used leaf-disc assays with fixed "natural" toxin ratios and only one adapted herbivore species, tests on living plants, other mixture designs, and non-adapted herbivores would make the broader conclusions stronger.
