ABSTRACT Sheep production contributes to a secure and diverse food and fibre supply in the United States, with growing ethnic diversity strengthening demand. Katahdin is a composite hair‐type sheep breed developed in the United States that has become the most popular breed in many regions of the country and the first one to have genomic selection ...

Epistasis in a model of molecular signal transduction. [PDF]
Biological functions typically involve complex interacting molecular networks, with numerous feedback and regulation loops. How the properties of the system are affected when one, or several of its parts are modified is a question of fundamental interest,

Phenotypic plasticity is broadly adaptive across an elevation gradient in the Cutleaf Monkeyflower
Leaf shape plasticity expression is variable in Mimulus laciniatus. Summary Phenotypic plasticity is a key mechanism by which organisms cope with environmental heterogeneity, but its evolutionary consequences depend on how plastic responses align with the broader adaptive landscape.

Structural Variations Contribute to Subspeciation and Yield Heterosis in Rice
ABSTRACT Yield heterosis has been extensively exploited in hybrid breeding, with intersubspecific hybrids often exhibiting the most pronounced effects. However, developing elite hybrids remains a laborious and time‐consuming process. The genetic basis of heterosis has been debated for over a century, hindered largely by the lack of high‐quality genomes.

Perspective:Sign Epistasis and Genetic Constraint on Evolutionary Trajectories
Epistasis for fitness means that the selective effect of a mutation is conditional on the genetic background in which it appears. Although epistasis is widely observed in nature, our understanding of its consequences for evolution by natural selection ...

Independently evolving populations may adapt to similar selection pressures via different genetic changes. The interactions between such changes, such as in a hybrid individual, can inform us about what course adaptation may follow and allow us to ...

ABSTRACT Cultivated peanut (Arachis hypogaea L.) is an important oilseed and cash crop, and seed sucrose content (SSC), seed oil content (SOC) and seed protein content (SPC) are key determinants of seed flavour, texture, and overall quality. Identifying quantitative trait loci (QTLs) and candidate genes associated with SSC, SOC and SPC is therefore of ...

A Novel AP2/ERF Transcription Factor Controls Trichome Initiation and Fruit Development in Cucumber
ABSTRACT Trichomes, the hair‐like outgrowths of the plant epidermis, are critical for defence, reproduction and development. However, the underlying molecular mechanisms governing their initiation remain elusive. Here, we identified CsGL2, an AP2/ERF transcription factor, as a key integrator controlling trichome initiation and fruit development in ...

ABSTRACT Rising nighttime temperature (Tnight) can reduce crop yields while low Tnight may restrict plant growth and development. Despite quantifiable effects of Tnight, genetic basis underlying plant responses to Tnight remains unclear. We investigated natural variation in long‐term response of effective photosynthetic efficiency (Fq’/Fm’) to Tnight ...
