ATXR5 and ATXR6 are H3K27 monomethyltransferases required for chromatin structure and gene silencing. [PDF]

open access: yes, 2009
Constitutive heterochromatin in Arabidopsis thaliana is marked by repressive chromatin modifications, including DNA methylation, histone H3 dimethylation at Lys9 (H3K9me2) and monomethylation at Lys27 (H3K27me1).

Lacandonia granules are present in the cell nucleus of Welwitschia mirabilis

open access: yesBotan‪ical Sciences, 2018
Background: Lacandonia granules are extranucleolar ribonucleoprotein (RNPs) particles, 32 nanometers in diameter that were first described in the nucleus of Lacandonia schismatica. Cytochemical and immunocytochemical studies suggest that these particles

Beyond species means – the intraspecific contribution to global wood density variation

open access: yesNew Phytologist, EarlyView.
Summary Wood density is central for estimating vegetation carbon storage and a plant functional trait of great ecological and evolutionary importance. However, the global extent of wood density variation is unclear, especially at the intraspecific level. We assembled the most comprehensive wood density collection to date, including 109 626 records from

Effects of Increased N Deposition on Leaf Functional Traits of Four Contrasting Tree Species in Northeast China

open access: yesPlants, 2020
Northeast China is persistently affected by heavy nitrogen (N) deposition. Studying the induced variation in leaf traits is pivotal to develop an understanding of the adaptive plasticity of affected species.

The evolutionary history of the ancient weevil family Belidae (Coleoptera: Curculionoidea) reveals the marks of Gondwana breakup and major floristic turnovers, including the rise of angiosperms

open access: yeseLife
The rise of angiosperms to ecological dominance and the breakup of Gondwana during the Mesozoic marked major transitions in the evolutionary history of insect-plant interactions.

Haplotype‐Resolved Genome Assembly and Population Genomics Reveal Evolutionary History and Agronomic Traits of Mulberry

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Mulberry is a representative economic tree species valued for both poverty alleviation and medicinal use. To advance the understanding of mulberry genomics and demography, we assembled high‐quality haploid genomes of two widely cultivated mulberry varieties NS14 and QS1, and analysed 376 accessions from 12 countries, including 39 ancient trees

Evolutionary Conserved and Divergent Responses to Copper Zinc Superoxide Dismutase Inhibition in Plants

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT After an initial evolution in a reducing environment, life got successively challenged by reactive oxygen species (ROS), especially during the great oxidation event (GOE) that followed the development of photosynthesis. Therefore, ROS are deeply intertwined into the physiological, morphological and transcriptional responses of most present‐day

Legacies from early‐season hot drought: how growth cessation alters tree water dynamics and modifies stress responses in Scots pine

open access: yesPlant Biology, EarlyView.
Early‐season hot drought in Scots pine limits growth and productivity but improves resilience to late‐season drought through reduced water use. Abstract Tree responses to drought are well studied, but the interacting effects of drought timing on growth, water use, and stress legacy are less understood.
