Speciation by physiological selection of environmentally acquired traits

The Journal of Physiology, 2023
AbstractA chance mutation affecting a single or extremely few individuals in a continuous population will be quickly diluted through interbreeding. Charles Darwin fully appreciated this difficulty with relying on natural selection alone, and suggested an enabling role for geographical isolation in the origin of species. However, Darwin also believed in

Adaptative Responses of Common and Tartary Buckwheat to Different Altitudes

Plants, 2022
Environmental conditions at different elevations are harsher at higher elevations and impose constraints upon plants. The response of common and Tartary buckwheats to environmental conditions at elevations between 300 and 1180 m above sea level (asl) was

Quantitative Trait Loci for Component Physiological Traits Determining Salt Tolerance in Rice [PDF]

Plant Physiology, 2001
Abstract Rice (Oryza sativa) is sensitive to salinity, which affects one-fifth of irrigated land worldwide. Reducing sodium and chloride uptake into rice while maintaining potassium uptake are characteristics that would aid growth under saline conditions.

Bayesian Sparse Factor Analysis of Genetic Covariance Matrices [PDF]

, 2013
Quantitative genetic studies that model complex, multivariate phenotypes are important for both evolutionary prediction and artificial selection. For example, changes in gene expression can provide insight into developmental and physiological mechanisms ...

Impact of Irrigation Levels and Weed Control Treatments on Annual Weeds, Physiological Traits and Productivity of Soybean under Clay Soil Conditions

Agronomy, 2022
Water scarcity and weed infestation are major challenges to soybean production. Therefore, two field experiments were conducted in a strip plot design including three replicates in the 2019 and 2020 summer seasons at Sakha Agricultural Research Station ...

Postcopulatory sexual selection [PDF]

, 2002
The female reproductive tract is where competition between the sperm of different males takes place, aided and abetted by the female herself. Intense postcopulatory sexual selection fosters inter-sexual conflict and drives rapid evolutionary change to ...

Genetic and morpho-physiological analyses of the tolerance and recovery mechanisms in seedling stage spring wheat under drought stress

Frontiers in Genetics, 2022
Drought is one of the complex abiotic stresses that affect the growth and production of wheat in arid and semiarid countries. In this study, a set of 172 diverse spring wheat genotypes from 20 different countries were assessed under drought stress at the

Functional traits of expanding, thicket-forming shrubs: contrasting strategies between exotic and native species [PDF]

, 2017
Woody expansion has been documented for decades in many different systems globally, often yielding vast changes in ecosystem functioning. While causes and consequences of woody expansion have been well documented, few studies have addressed plant ...

Physiological Traits for Improving Heat Tolerance in Wheat   [PDF]

Plant Physiology, 2012
Wheat ( Triticum aestivum ) represents about 30% of the world’s cereal area, with over 220 million ha cultivated worldwide, often under abiotic stress. Wheat growth can be impaired by heat stress ([HS][1]) at any developmental stage, and modeling scenarios predict even warmer temperatures in ...
