Aggregation and the Structure of Value

open access: yesNoûs, EarlyView.
ABSTRACT Roughly, the view I call “Additivism” sums up value across time and people. Given some standard assumptions, I show that Additivism follows from two principles. The first says that how lives align in time cannot, in itself, matter. The second says, roughly, that a world cannot be better unless it is better within some period or another.

Seeing herbaria in a new light: leaf reflectance spectroscopy unlocks trait and classification modeling in plant biodiversity collections

open access: yesNew Phytologist, EarlyView.
Summary Reflectance spectroscopy is a rapid method for estimating traits and discriminating species. Spectral libraries from herbarium specimens represent an untapped resource for generating broad phenomic datasets across space, time, and taxa. We conducted a proof‐of‐concept study using trait data and spectra from herbarium specimens up to 179 yr old,

Chromatin‐associated DEK proteins maintain H3K27me3 balance and coordinate developmental transitions in plants

open access: yesNew Phytologist, EarlyView.
Summary Chromatin organization and histone modifications play essential roles in regulating gene expression during development. DEK is a conserved chromatin‐associated protein implicated in DNA topology and transcriptional regulation, yet its in vivo function in plants has remained elusive.

Defender or accomplice? Dual roles of plant vesicle trafficking in restricting and enabling geminiviral systemic infection

open access: yesNew Phytologist, EarlyView.
Summary The vesicle trafficking system enables multidirectional cargo fluxes between endomembrane compartments. However, vesicle trafficking plays dual roles during pathogen infections. In plants, it mediates autophagic immune responses but can also be hijacked by pathogens to facilitate successful infections.
