Evolution of crop phenotypic spaces through domestication. [PDF]

New Phytol
Summary We used domestication as an in vivo replicated experiment to investigate how divergent selection has shaped the evolution of multivariate phenotypic spaces. We measured 11–57 qualitative and quantitative traits in 13 species, either unique or shared between species, and established a framework for cross‐species comparisons. Our results revealed

Parentage Analysis in a Green Sea Turtle (<i>Chelonia mydas</i>) Population From French Polynesia Reveals a Tendency for Inbreeding and Unexpected Plasticity in Reproductive Behaviour. [PDF]

Ecol Evol
In this study, we examine the mating system of an endangered population of green sea turtles in Tetiaroa, French Polynesia, through genotype reconstruction and parentage analysis. We unravelled the mating behaviours of both males and females and determined if they serve as strategies to avoid inbreeding by investigating levels of relatedness between ...

Unravelling ecophysiological and molecular adjustments in the photosynthesis-respiration balance during Fusarium graminearum infection in wheat spikes. [PDF]

Physiol Plant
Abstract Wheat responses to F. graminearum result in a deep and sharp reprogramming of a wide range of biological processes, including energy‐associated functions and related metabolisms. Although these impacts have been thoroughly described at the molecular scale through proteomics and transcriptomics studies, phenotypic studies are still needed to ...

Conservation genetics of the white-bellied pangolin in West Africa: A story of lineage admixture, declining demography, and wide sourcing by urban bushmeat markets. [PDF]

Ecol Evol
Our work derives from an unprecedented, exhaustive genetic survey of the pangolin trade in three countries from West Africa (Guinea, Cote d'Ivoire, and Ghana). Our study combining mitochondrial DNA sequencing and microsatellite genotyping is the first to reveal a global pattern of admixture between two of the six mitochondrial lineages previously ...
