Floral shape and color impact heat accumulation and thermal stability of the floral microenvironment in a subalpine meadow

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise The floral thermal microenvironment impacts plant reproduction through its effects on gametophyte performance and plant–pollinator interactions. Color and shape are axes of floral variation that may mediate floral temperature because they affect the absorption and reflection of solar radiation, but their interactive effects are unclear.

Stacked scattering: The key to bright flowers lies in the mesophyll

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise The coloration of flowers is caused by wavelength‐selective absorption by pigments and scattering of light by floral structures. Although the molecular, physiological, and chemical properties of floral pigments have been studied in considerable detail, how floral structures contribute to the visual signal remains largely unknown.

Reconstructing the evolutionary history of herbaceous crops through trait‐based ecology

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Reconstructing the evolution of crop plants is fundamental to understanding their origins, ecological adaptations, and impacts on ecosystem processes. However, our understanding of crop evolution stems largely from archaeology and genetics, with less focus on a trait‐based ecological approach.

Identification and Characterization of a Novel Biallelic SLC12A2 Variant Associated With Kilquist Syndrome (OMIM #619080)

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT This study presents the case of a child with multiple congenital anomalies, severe hypotonia, and profound bilateral sensorineural hearing loss. Functional bioenergetic assessments showed no significant mitochondrial respiratory defects, and riboflavin (Rf) status evaluation excluded a deficiency in Rf transporters as a cause of hearing loss ...
