Abstract:
... Impacts of climate change are apparent in natural systems around the world. Many species are and will continue to struggle to persist in their current location as their preferred environment changes. Traditional conservation efforts aiming to prevent local extinctions have focused on two aspects that theoretically enhance genetic diversity—population connectivity and population size—through ‘passi ...

Abstract:
... When prey experience size‐based harvesting by predators, they are not only subject to selection due to larger individuals being preferentially harvested but also selection due to reductions in population density. Density‐dependent selection represents one of the most basic interactions between ecology and evolution. Yet, the reduction in density associated with exploitation has not been tested as ...

Abstract:
... KEY MESSAGE: we identified a functional chromogen gene C from wild rice, providing a new insight of anthocyanin biosynthesis pathway in indica and japonica. Accumulation of anthocyanin is a desirable trait to be selected in rice domestication, but the molecular mechanism of anthocyanin biosynthesis in rice remains largely unknown. In this study, a novel allele of chromogen gene C, OrC1, from Oryza ...

Abstract:
... Ectotherms can respond to global warming via evolutionary change of their upper thermal limits (CTₘₐₓ). Thus, the estimation of CTₘₐₓ and its evolutionary potential is crucial to determine their vulnerability to global warming. However, CTₘₐₓ estimations depend on the thermal stress intensity, and it is not completely clear whether its evolutionary capacity can be affected. Here, we performed an a ...

Abstract:
... Breeding or genetic improvement refers to the process of artificial selection following domestication; as such, it has had a major influence on modern agriculture and animal production. Improvement generally focuses on traits that greatly affect the economic performance. Therefore, understanding the genetic basis underlying improvement will contribute to the identification of genes controlling eco ...

Abstract:
... Many crops are polyploid or have a polyploid ancestry. Recent phylogenetic analyses have found that polyploidy often preceded the domestication of crop plants. One explanation for this observation is that increased genetic diversity following polyploidy may have been important during the strong artificial selection that occurs during domestication. In order to test the connection between domestica ...

Abstract:
... Macroalgal domestication and farming can induce significant ecological and biological changes in exploited species. In the red macroalga, Agarophyton chilense, marine farming is based on clonal propagation by cuttings of the largest plants. This type of mass selection by farmers can have a considerable impact on the life history characteristics of cultivated strains. In this study we investigated ...

Abstract:
... Artificial group selection has long been proposed as a useful method for crop breeding, yet the possibility that group selection occurs naturally in agroecosystems has not been explored. Due to natural and/or artificial selection, the fitness of an individual can depend on both the individual’s traits, the traits of neighboring individuals, and on group’s emergent traits (as density). This process ...

Abstract:
... Highly efficient and accurate selection of elite genotypes can lead to dramatic shortening of the breeding cycle in major crops relevant for sustaining present demands for food, feed, and fuel. In contrast to classical approaches that emphasize the need for resource-intensive phenotyping at all stages of artificial selection, genomic selection dramatically reduces the need for phenotyping.

Abstract:
... When the JCVI-syn3.0 genome was designed and implemented in 2016 as the minimal genome of a free-living organism, approximately one-third of the 438 protein-coding genes had no known function. Subsequent refinement into JCVI-syn3A led to inclusion of 16 additional protein-coding genes, including several unknown functions, resulting in an improved growth phenotype. Here, we seek to unveil the biolo ...

Abstract:
... The metabolic, physiological, and behavioral processes in most of the living organisms exhibit an approximate 24-h rhythmic, self-sustained circadian (L. circa = about, dies = day) oscillations. These oscillations, apart from passively persisting in synchrony with external cues, exist in their absence as well, conferring adaptive advantage by following environmental cycle (extrinsic adaptation) an ...

Abstract:
... The impact of sexual selection on the adaptive process remains unclear. On the one hand, sexual selection might hinder adaptation by favouring costly traits and preferences that reduce nonsexual fitness. On the other hand, condition dependence of success in sexual selection may accelerate adaptation. Here, we used replicate populations of Drosophila melanogaster to artificially select on male desi ...

Abstract:
... Brassicaceae (Cruciferae) are ostensibly defended in part against generalist insect herbivores by toxic isothiocyanates formed when protoxic glucosinolates are hydrolysed. Based on an analysis of published host records, feeding on Brassicas is widespread by both specialist and generalists in the Lepidoptera. The polyphagous noctuid moth Helicoverpa armigera is recorded as a pest on some Brassicas ...
