Journal of Integrative Plant Biology, Volume 68, Issue 8, Page 2368-2387, August 2026.This review examines salt glands in exo‐recretohalophytes, in which epidermal stem cells differentiate into unicellular, bicellular, or multicellular salt glands. Salt ions are transported to the leaves via the transpiration stream and enter salt glands through symplastic and apoplastic pathways. Finally, salt glands actively secrete salt ions from the

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 ...

Re‐Examining Historical Trends of Tropical Cyclone Frequency
Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract The short duration of high‐quality, reliable tropical cyclone (TC) observations limits our ability to detect long‐term trends. Here, we analyze TC frequency trends in the NOAA 20th Century Reanalysis (20CR) versions 3 and 2c over the 19th and 20th centuries.
