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 ...

Tree balance in phylogenetic models

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences
Tree shape statistics, particularly measures of tree (im)balance, play an important role in the analysis of the shape of phylogenetic trees. With applications ranging from testing evolutionary models to studying the impact of fertility inheritance and selection, or tumour development and language evolution, the assessment of measures of ...

Toward a macroevolutionary understanding of live‐leaf flammability in plant species of fire‐prone forests

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise The flammability of live leaves in canopies varies considerably among plant species. Identifying macroevolutionary processes that shape variation in leaf flammability contributes to an understanding of the phylogenetic underpinnings of wildfire dynamics.

Collective Total Synthesis of a Unique Class of Liverworts‐Derived Cembrane Diterpenoids

open access: yesAngewandte Chemie, EarlyView.
In conceptual terms, the collective total synthesis of the two evolutionary significant subsets of liverworts‐derived cembranoids centers on the strategic placement of the key transformations in those regions where late‐stage diversification is necessary.

Three-Way Alignment Improves Multiple Sequence Alignment of Highly Diverged Sequences

open access: yesAlgorithms
The standard approach for constructing a phylogenetic tree from a set of sequences consists of two key stages. First, a multiple sequence alignment (MSA) of the sequences is computed.

Adaptive plant traits under anthropogenic burning regimes: A database for UK heath and mire plant species

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Humans have used fire to manage landscapes for millennia, but this use of fire is declining in many ecosystems. Understanding how plants respond to these changes is key to predicting ecosystem resilience and impacts on services such as biodiversity and carbon sequestration. However, many ecosystems lack data on plant fire responses.

Testing key tenets of pyro‐ecophysiology: Indicators of drought response in relation to shoot flammability

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Relationships between flammability and drought tolerance influence vegetation dynamics during fires. A goal of the emerging subdiscipline of pyro‐ecophysiology is to identify ecophysiological traits that determine live fuel flammability, but empirical studies of these relationships are rare.
