A century of theories of balancing selection
Biological Reviews, Volume 101, Issue 2, Page 804-825, April 2026.ABSTRACT Traits that affect organismal fitness are often highly genetically variable. This genetic variation is vital for populations to adapt to their environments, but it is also surprising given that nature – after all – ‘selects’ the best genotypes at the expense of those that fall short.

Identification and Characterization of the PEBP Family Genes in Moso Bamboo (Phyllostachys heterocycla). [PDF]
, 2019 Moso bamboo is one of the economically most important plants in China. Moso bamboo is a monocarpic perennial that exhibits poor and slow germination. Thus, the flowering often causes destruction of moso bamboo forestry.

Evolution, 2019 Heritable genetic variation is necessary for populations to evolve in response to anthropogenic climate change. However, antagonistic genetic correlations among traits may constrain the rate of adaptation, even if substantial genetic variation exists.

Tissue Culture as a Source of Replicates in Nonmodel Plants: Variation in Cold Response in Arabidopsis lyrata ssp. petraea [PDF]
, 2016 While genotype–environment interaction is increasingly receiving attention by ecologists and evolutionary biologists, such studies need genetically homogeneous replicates—a challenging hurdle in outcrossing plants.

, 2021 Circadian clocks manifest adaptations to predictable 24-h fluctuations in the exogenous environment, but it has yet to be determined why the endogenous circadian period length in the wild varies genetically around the hypothesized optimum of 24 h. We quantified genetic variation in circadian period in leaf movement in 30 natural populations of the ...

, 2021 Differential local adaptation restricts gene flow between populations inhabiting distinct environments, resulting in isolation by adaptation. In addition to the statistical inferences of genotype-environment associations, an integrative approach is needed to investigate the effect of local adaptation on population divergence at the ecological, genetic ...

Temperature and the evolution of flower color: A review
American Journal of Botany, Volume 113, Issue 1, January 2026.Abstract Flower colors brighten our natural world. How and why have they evolved? How might ongoing global warming alter their evolutionary trajectories? In this review, I examine the influence of ambient temperature on the evolution of flower color.

Ecosphere, Volume 17, Issue 1, January 2026.Abstract All plant organs have the potential to harbor microbial communities and each organ may form unique niches for specialized microbial communities. There have been very few detailed investigations of microbiomes within a single plant organ along different developmental stages.

Status and Role of Antioxidant Enzymes in Sexual and Apomictic Species of \u3cem\u3eBoechera\u3c/em\u3e [PDF]
, 2020 Enzymatic and non-enzymatic antioxidation systems provide protection against the toxic effects of activated oxygen species including scavenging H2O2. It is evident that during stress plants produce different ROS which play a negative role in regulating ...
