Two New Species of Tricoma (Tricoma) (Nematoda: Desmoscolecidae) from Korean Subtidal Sediments, with Notes on Labial Ultrastructure

Journal of Marine Science and Engineering
This paper reports two newly discovered species of Tricoma (Tricoma)—T. (T.) discrepans sp. nov. and T. (T.) parasetosa sp. nov.—obtained from the subtidal sediments at a depth of 13 m around Jindo Island, Korea. Tricoma (T.) discrepans sp. nov. differs from its congeners in possessing 40–41 main rings, an uncovered first main ring, large vesicular ...

A drought stress‐induced MYB transcription factor regulates pavement cell shape in leaves of European aspen (Populus tremula)

New Phytologist, Volume 251, Issue 5, Page 2688-2705, September 2026.
MYB305a promoter expression increases in pavement cells as they grow and acquire their complex shape. Summary Leaf pavement cells of many plant species develop jigsaw puzzle‐like shapes in which neighboring cells interdigitate, providing an ideal model for the study of cell shape regulation.

Endogenous RALF peptide function is required for powdery mildew host colonization

New Phytologist, Volume 251, Issue 4, Page 2073-2090, August 2026.
Model of RALF‐FER‐dependent effects on powdery mildew sporulation. Summary The receptor kinase FERONIA (FER) is a susceptibility factor for biotrophic powdery mildew fungal pathogens in Arabidopsis thaliana, but the underlying molecular mechanisms remain largely unknown. FER is required for the perception of endogenous RAPID ALKALINIZATION FACTOR (RALF)

The underappreciated roles of fog and dew on vegetation and biocrusts

New Phytologist, Volume 251, Issue 1, Page 46-63, July 2026.
Summary Fog and dew represent minor components of ecosystem water budgets in most ecosystems. However, fog and dew can play an essential role in ecosystem dynamics and are particularly important for water‐limited systems. In addition to serving as direct water inputs, fog and dew can influence microclimate and water redistribution, thereby promoting ...
