The cryo-EM structure of the PSI–LHCI photosystem supercomplex from Physcomitrium patens shows that the red-shifted Lhca4 antenna is replaced by an Lhca2 paralogue. The structure demonstrates an adaptation of mosses to low light.
Loading of osmolytes into the phloem drives a pressure-flow transport mechanism. A maize sucrose transporter1 loss-of-function mutant has much reduced export of carbon from leaves, but increased potassium concentrations maintain phloem pressure.
The bound loci and functions of chromatin-associated RNAs remain unclear in rice. This study develops an RNA–DNA mapping method to reveal the identity and interaction patterns around active promoters within hierarchical genome architecture.
This paper examines the small proportion of trees that vastly outlive the median age for their species, and classify three age classes to analyse how these ‘lottery winners’ impact forests.
Mistakes in the maintenance of CG methylation are a source of heritable epimutations in plants. This study systematically identifies and characterizes epimutation hotspots along the Arabidopsis genome and dissects their molecular properties.
The essential nutrient magnesium is mainly stored in the plant vacuole. Arabidopsis proteins identified by homology to a yeast Mg transporter mediate vacuolar Mg sequestration.
