Epigenetic regulation of mycorrhizal symbioses: from plastic responses to transgenerational legacies

open access: yesNew Phytologist, Volume 250, Issue 3, Page 1438-1452, May 2026.
Summary Mycorrhizal symbioses represent one of the most widespread and ecologically significant plant–microbe interactions, shaping plant nutrition, stress resilience, and ecosystem functioning. Beyond their role in nutrient exchange and systemic defense, growing evidence suggests that these symbioses also influence plant plasticity within and across ...

Floral Temperatures of the Southern‐Most Flowering Amorphophallus titanum and Seedling Growth Following Self‐Pollination

open access: yesNew Zealand Journal of Botany, Volume 64, Issue 1, March 2026.
Amorphophallus titanum (Becc.) Becc. (Araceae) is native to the rainforests of Sumatra, and famously produces a single, massive, thermogenic, and highly odoriferous inflorescence. Despite having both male and female flowers in close proximity, A. titanum does not readily self‐pollinate as it is strictly dichogamous, with female flowers receptive on the

HvTT8 Regulates Proanthocyanidin Accumulation in the Barley Testa Layer by Transcriptionally Activating the Flavonoid Biosynthesis Pathway

open access: yesPlant Direct, Volume 10, Issue 3, March 2026.
ABSTRACT Barley accumulates proanthocyanidins (PA), a type of flavonoid compound, in the testa layer. The accumulated PA have a detrimental effect on the quality of beer and pearled barley. Therefore, controlling PA accumulation in the testa layer is an important breeding objective in barley. PA accumulation is regulated by a ternary complex consisting
