Climate adaptation and functional constraints drive pollen evolution in Apiales

New Phytologist, Volume 249, Issue 5, Page 2574-2587, March 2026.
Summary Pollen grains exhibit remarkable morphological diversity, shaped by selective pressures from environmental factors and mechanical constraints. Here, we investigate macroevolutionary patterns of pollen morphology in Apiales, an order of angiosperms with significant ecological and geographical diversity, to disentangle the roles of climate and ...

The effect of salubrinal on the endoplasmic reticulum stress pathway in heat‐stressed spermatogonial cells in vitro

FEBS Open Bio, Volume 16, Issue 2, Page 340-351, February 2026.
This study investigates the protective role of salubrinal against heat‐induced endoplasmic reticulum (ER) stress in mouse spermatogenic cells (GC1 and GC2). By modulating the ER stress pathway, salubrinal alleviates cellular stress and supports spermatogenic cell survival, suggesting its potential as a therapeutic candidate for heat‐related infertility.

CCDC41 Drives Oocyte Meiotic Progression by Promoting Rab11a/Rab7‐Positive Vesicle Fusion with Target Membranes

Advanced Science, Volume 13, Issue 8, 9 February 2026.
CCDC41 is essential for meiotic maturation in mouse oocytes through regulating Rab7‐positive endosomes fusion with lysosomes and Rab11a‐positive vesicle fusion with the plasma membrane. Abstract Coiled‐coil domain‐containing protein 41 (CCDC41), a core component of centriolar distal appendages involved in centriole assembly and ciliary vesicle docking,

Bisphenol B Exposure Induces Miscarriage by Suppressing Migration/Invasion and Migrasome Formation

Advanced Science, Volume 13, Issue 7, 3 February 2026.
BPB (Bisphenol B) exposure up‐regulates ER (estrogen receptor) levels, enhances its interactions with the lnc‐HZ04 promoter region, and thus promotes ER‐mediated lnc‐HZ04 transcription. Subsequently, lnc‐HZ04 suppresses TCF4 (transcription factor 4)‐mediated PKCA (protein kinase C alpha) transcription and subsequently suppresses migration/invasion and ...

Mycoponics: Controlled Bioproduction Utilizing Biophysical, Solid‐State, Liquid Nutrient Delivery

Biotechnology Journal, Volume 21, Issue 2, February 2026.
Graphical Abstract and Lay Summary Mycoponic biotechnology, inspired by hydroponics—is enabled by antimicrobial ceramics as “substrate,” using a complete mycoponic media for continuous bioproduction of mycelial and mushroom products. Applications include food, mycoleather, and mycopharmaceuticals, representing 18% of the global market.
