Ramping It Up: Assessing Genetic Diversity of the Allium tricoccum complex Aiton (Alliaceae) in Great Smoky Mountains National Park with Next-Gen Sequencing

Lauren A. Gray, Cameron W. Corbett, Craig F. Barrett, Jennifer Rhode Ward et autres

In an era of unprecedented biodiversity loss, understanding the extent to which species lose genetic diversity is imperative for conservation efforts. Reduced genetic diversity can cause species to be less resilient to stochastic change and more susceptible to extirpation and possibly extinction. …

New microsatellite markers distinguish two species of ramps (Allium tricoccum Aiton Complex, Amaryllidaceae) and show variation in clonality and genetic diversity between species and among populations

Sarah E. Nilson, Matt C. Estep, Eric P. Burkhart, Harvey E. Ballard et autres

A ramp (Allium tricoccum Aiton), or wild leek, is a perennial herbaceous plant native to the forests of eastern North America. Like other members of the Allium genus, ramps produce sulfur-containing compounds that give them culinary and medicinal appeal. Ramps reproduce clonally …

Ramps ( Allium tricoccum Aiton) as a Wild Food in Northern Appalachia

Cathryn V. Pugh, Eric P. Burkhart, Sarah E. Nilson, Joshua D. Lambert

Ramps (Allium tricoccum Aiton) are an edible wild allium native to Eastern North America. Ramp harvesting is an important tradition for both indigenous and non-indigenous Appalachian communities. In recent years, ramps have grown in popularity, especially in urban areas beyond their native …

Habitat Associated with Ramps/Wild Leeks (Allium tricoccum Ait.) in Pennsylvania, USA: Guidance for Forest Farming Site Selection

Ezra Houston, Eric P. Burkhart, Cassie Stark, Xin Chen et autres

Ramps or wild leeks (Allium tricoccum) are a popular foraged non-timber forest product in North America consumed for their edible bulbs and leaves. The agroforestry practice of forest farming is a possible solution to conservation challenges surrounding the wild exploitation of this …

Two Ramp Taxa, Allium tricoccum and A. burdickii, Differ in Abiotic Habitat Characteristics and Floristic Associates in Pennsylvania

Cassie Stark, Sarah E. Nilson, Eric P. Burkhart

The name ramp or wild leek refers to two taxa: Allium tricoccum and A. burdickii. The latter, named narrow-leaf ramp, has historically been recognized as a variety but recently as a distinct species. Habitat differences between these species have been reported, although …

The α-Subunit of the Arabidopsis Heterotrimeric G Protein, GPA1, Is a Regulator of Transpiration Efficiency

Sarah E. Nilson, Sarah M. Assmann

Land plants must balance CO2 assimilation with transpiration in order to minimize drought stress and maximize their reproductive success. The ratio of assimilation to transpiration is called transpiration efficiency (TE). TE is under genetic control, although only one specific gene, ERECTA, has …

Heterotrimeric G proteins regulate reproductive trait plasticity in response to water availability

Sarah E. Nilson, Sarah M. Assmann

Phenotypic plasticity is the ability of one genotype to display different phenotypes under different environmental conditions. Although variation for phenotypic plasticity has been documented in numerous species, little is known about the genetic mechanisms underlying phenotypic plasticity. Given their widespread roles in …
