Flood induced phenotypic plasticity in amphibious genus Elatine (Elatinaceae)

Editor rating: 7 / 10

Luis Eguiarte –– This paper seems to be the most important contribution for this group of poorly known plants in a long time, and shows the plasticity of the vegetative traits in the genus. The study will be useful for the future understanding of the group, in particular for solving taxonomic and conservation issues.
A new threat to bees? Entomopathogenic nematodes used in biological pest control cause rapid mortality in Bombus terrestris

Alexander Mikheyev –– Potentially important finding about the unexpected consequences of biocontrol.
No apparent correlation between honey bee forager gut microbiota and honey production

Editor rating: 7 / 10

Valeria Souza –– the problem of bee colonies been abandoned is a global issue for agriculture, however, even if the observations are not so new, as the second reviewer noted, the issue still controvertial

Ilaria Negri –– It will help highlight the symbiotic relationship between the insect model Drosophila and yeasts
Divergent thermal specialisation of two South African entomopathogenic nematodes

Editor rating: 7 / 10

Nigel Andrew –– Thermal physiology is a key discipline for many taxa. This work on nematodes crosses between theoretical research and applied research, thus making it an excellent publication for PeerJ
Genetic architecture of pollination syndrome transition between hummingbird-specialist and generalist species in the genus Rhytidophyllum (Gesneriaceae)

Editor rating: 7 / 10

Felix Forest –– As stated by one of the reviewers, this study is well executed and brings new information to the field of pollination biology.
Natural variation in teosinte at the domestication locus teosinte branched1 (tb1)

Editor rating: 7 / 10

Todd Vision –– The authors show that a hopscotch transposable element insertion in a regulatory region upstream of the maize domestication gene tb1 is part of the standing variation within the wild progenitor of maize, teosinte. This polymorphism seems to have been under selection, and hopscotch is very unlikely to have been driven to high frequency in some populations via gene flow from maize. Yet, in teosinte, there is not evidence that this locus alone contributes to the "maize domestication phenotype" of reduced tillering under crowding, and variation in the frequency of the insertion is not associated with obvious environmental differences among populations. This suggests that the maize apical dominance phenotype may result from epistasis between the the hopscotch insertion at tb1 and other yet to be identified loci, and that the high frequency of the hopscotch insertion in some teosinte populations is due to an unknown and unrelated phenotypic effect.
Comparative genomics and phylogenetic discordance of cultivated tomato and close wild relatives

Editor rating: 8 / 10

Gerard Lazo –– This work made good use of existing reference genomes for the Solanaceae and contributed additional sequencing efforts from related species. I am aware of some contentions regarding the phylogeny of species within this plant family and the methods used here provide some ways of resolving these issues.
Intragenomic polymorphisms among high-copy loci: a genus-wide study of nuclear ribosomal DNA in Asclepias (Apocynaceae)

Editor rating: 8 / 10

Gerard Lazo –– The authors present tools that can be tested and provide a data-set that can be evaluated. Though the end results may not sway the community in its current methods, it does provide yet another testable feature which will add value in the long-run.

@EvoEcoAmy In Rhytidophyllum (Gesneriaceae), nectar volume is not correlated to corolla shape nor flower color. Moreover, QTL mapping suggests they are not genetically linked. https://t.co/7pI7MUVoCD https://t.co/xdPGbN4eU1

@ellstrand Thanks. But doesn’t show sh4 isn’t dom locus, just can’t be only explanation. We see similar tb1 result in teosinte https://t.co/4yFkG2NL7u
