Dual recognition specificity of an MLA immune receptor in barley demonstrates that the deployment of mildew-resistant cultivars by plant breeders has unintentionally affected nonhost resistance to wheat stripe rust.

The difference in phloem pressure is the driving force that moves photosynthetic products and other solutes from the source to the sink. Measurements with emerging technologies reveal that sugar loading is not essential for maintaining phloem pressure and phloem bulk flow in the maize sugar-loading-defective mutant sut1.

Equatorial latitudes are often assumed to be regions of high biodiversity from which new species radiate. However, late Silurian–Early Devonian strata show that during their first major diversification, land plants were less diverse in the tropics.

Over-expressing TaWOX5 substantially increases the transformation efficiencies of wheat and other cereals, including barley and maize, with reduced genotype dependency, and transformed transgenic plants can readily be screened using a visible phenotype.

The crucial enzyme for photosynthesis, Rubisco, is deactivated during periods of shade and slowly recovers when illuminated. In fluctuating light conditions crop productivity could be substantially increased by slowing Rubisco deactivation during shade.

This paper reports the discovery of two fossils of Rhamnaceae preserved in amber that provide evidence of fire adaptation in Cretaceous angiosperms.

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 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.

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 essential nutrient magnesium is mainly stored in the plant vacuole. Arabidopsis proteins identified by homology to a yeast Mg transporter mediate vacuolar Mg sequestration.
