Envisaging an Effective Global Long-Term Agrobiodiversity Conservation System That Promotes and Facilitates Use

open access: yesPlants, 2021
Genebanks were established out of a recognised need not just to provide genetic variation to support breeding objectives but to prevent crop diversity from being lost entirely for future users. Such conservation objectives may have led, over the past few

Genetic diversity and kelp forest vulnerability to climatic stress

open access: yesScientific Reports, 2018
Genetic diversity confers adaptive capacity to populations under changing conditions but its role in mediating impacts of climate change remains unresolved for most ecosystems.

Genetic diversity and genetic burden in humans

open access: yesInfection, Genetics and Evolution, 2006
We discuss categories of genetic diversity in humans. Neutral diversity, population differences in frequencies of genetic markers that we think are invisible to natural selection, provides a passive record of population history but is otherwise of little interest in human biology.

Human capital and genetic diversity [PDF]

open access: yesEurasian Economic Review, 2018
This paper investigates the relationship between human capital and the ancestral genetic diversity of populations. A simple model highlights a new channel through which genetic diversity can affect development: human capital. Additionally, empirical evidence of an unconditional hump-shaped relationship between genetic diversity and human capital is ...

Interaction vesicles as emerging mediators of host‐pathogen molecular crosstalk and their implications for infection dynamics

open access: yesFEBS Letters, EarlyView.
Interaction extracellular vesicles (iEVs) are hybrid vesicles formed through host‐pathogen communication. They facilitate immune evasion, transfer pathogens' molecules, increase host cell uptake, and enhance virulence. This Perspective article illustrates the multifunctional roles of iEVs and highlights their emerging relevance in infection dynamics ...

Vegetative propagation of Phytolacca acinosa Roxb. by rhizome cuttings: a step towards conservation and cultivation approach

open access: yesFrontiers in Conservation Science
IntroductionPhytolacca acinosa Roxb. is a highly valuable multipurpose herb native to the Himalayan region. Unsustainable harvesting of this species due to its diverse uses has resulted in a rapid decline in its population across natural habitats ...

Worldwide phylogeography and history of wheat genetic diversity

open access: yesScience Advances, 2018
A phylogeographical study reveals the reshuffling of wheat genetic diversity through time, in relation to human history. Since its domestication in the Fertile Crescent ~8000 to 10,000 years ago, wheat has undergone a complex history of spread ...

A stepwise emergence of evolution in the RNA world

open access: yesFEBS Letters, EarlyView.
How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

Genetic diversity in a crop metapopulation [PDF]

open access: yesHeredity, 2009
The need to protect crop genetic resources has sparked a growing interest in the genetic diversity maintained in traditional farming systems worldwide. Although traditional seed management has been proposed as an important determinant of genetic diversity and structure in crops, no models exist that can adequately describe the genetic effects of seed ...

B cell mechanobiology in health and disease: emerging techniques and insights into therapeutic responses

open access: yesFEBS Letters, EarlyView.
B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...
