Barley HvBODYGUARD1 controls cuticular specialisations regulated by SHINE transcription factors

New Phytologist, Volume 251, Issue 3, Page 1188-1208, August 2026.
Cuticle defects result from defective HvBDG1 alleles. Summary Land plants secrete a protective outer cuticular layer with diverse functions. Barley (Hordeum vulgare L.) develops two cuticular specialisations: the β‐diketone rich wax bloom on vegetative tissues and an adherent grain surface which sticks to the hulls, leading to barley's distinctive ...

Neglected seed dispersers and research compartmentalisation: how much do we know about what we don't know?

New Phytologist, Volume 251, Issue 3, Page 967-974, August 2026.
Geographic distribution of seed dispersal studies by disperser guild. Summary Seed dispersal is critical for long‐term ecosystem resilience. However, excessive compartmentalisation of research into particular disperser guilds (e.g. birds) hampers our understanding of their relative contributions to overall seed dispersal, risking erroneous conclusions ...

Investigating GERMs: how genotype, environment, and rhizosphere microbiome interactions underlie heat response in maize and sorghum

New Phytologist, Volume 251, Issue 4, Page 2152-2167, August 2026.
Three genotypes – a heat‐resistant maize (Zea mays), a heat‐susceptible maize, and a sorghum (Sorghum bicolor) variety – were grown to the V4 stage in growth chambers under optimal conditions or subjected to heat stress. Plants were grown in soil containing a complex microbial community, or in the same soil with a depleted microbiome.
