Toward a functional understanding of novel fire regimes in tropical forests

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Climate change and land‐use alterations are driving forest fires to unprecedented frequencies and intensities worldwide. Even wet tropical forests—historically rarely subjected to fire—are increasingly experiencing fire disturbances. The impact of wildfires on these forests is likely large, since many of their tree species are not adapted to ...

Causes of delayed angiosperm diversification: The photosynthetic revolution, increased opportunity costs of anti‐herbivore defenses, selection for qualitative toxins, and acceleration of plant–herbivore coevolution

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Why did it take so long for angiosperms to diversify after they arose? Here I consider the indirect but potentially crucial impact of the “photosynthetic revolution” on plant–herbivore coevolution. Increased vein density in fossil leaves implies a doubling in photosynthesis 125–100 million years ago.

Unravelling the Functional Diversity of Type III Polyketide Synthases in Fungi

open access: yesAngewandte Chemie, EarlyView.
Type III polyketide synthases (T3PKSs) produce diverse compounds of ecological and clinical importance. Here, the activity of 37 fungal T3PKSs was profiled, revealing unexpected products and generating several pharmaceutical precursors. The machine learning model trained on the activity data accurately extrapolates the predictions to other enzymes and ...

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 ...
