Re-evaluating Student Treatments of Barkcloth Artefacts from the Economic Botany Collection, Royal Botanic Gardens, Kew [PDF]

, 2017
Since 1995 textile conservation students have treated 17 pieces of barkcloth from the Economic Botany Collection, Royal Botanic Gardens, Kew. A re-examination of 8 treated objects has enabled comparison of the effectiveness of interventive treatments ...

Pollinator, herbivore, and climatic selective pressures differ across a floral color transition zone

American Journal of Botany, EarlyView.
Abstract Premise Spatial and temporal variations in climate and ecological interactions may underlie the origin and maintenance of floral color polymorphisms across a species range. Betalains are nitrogen‐containing, phylogenetically restricted pigments that, like the widespread and well‐studied anthocyanins and carotenoids, may attract pollinators ...

Factors accounting for limited sexual reproduction in a long-lived unisexual plant species

Frontiers in Plant Science
IntroductionPlant dispersal directly depends on reproduction success, and hence, on sexual systems. In bryophytes, wherein fertilization involves a continuous film of water between male and female sexual organs, reproduction in unisexual species involves

Intraspecific variation in stomatal architecture, gas exchange, and drought response of a dominant prairie grass sourced from broad climatic gradients

American Journal of Botany, EarlyView.
Abstract Premise Understanding how plant populations adapt to water limitation through stomatal traits is key to predicting drought responses. The dominant C4 grass Andropogon gerardi, distributed across sharp climate gradients in North America, offers an excellent focal species to study stomatal architecture (size and density).

Expanded application to plant reproductive tissues of a branched DNA probe‐based in situ hybridization method

Applications in Plant Sciences, EarlyView.
Abstract Premise Detecting clear tissue‐ and organ‐specific patterns of gene expression is key to understanding the genetic mechanisms that control plant development. In situ hybridization (ISH) of mRNA is one of the most precise, yet most challenging approaches to gene expression assays.
