Morphology and ultrastructure of Tilioideae pollen: how to differentiate Craigia, Mortoniodendron, and Tilia [PDF]

Botanical Studies
Assigning fossil Tilioideae pollen grains to the extant genera Craigia, Mortoniodendron, and Tilia is difficult. Firstly, the pollen from these genera appears similar when studied only with light microscopy.

Climate adaptation and functional constraints drive pollen evolution in Apiales [PDF]

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 ...

Redundant Glycerol‐3‐Phosphate Acyltransferases Regulate Thermo‐Sensitive Genic Male Sterility in Rice [PDF]

Plant Biotechnology Journal, Volume 24, Issue 7, Page 4689-4703, July 2026.
ABSTRACT Thermo‐sensitive genic male sterility (TGMS) lines play a pivotal role in two‐line hybrid rice breeding. However, the availability of elite TGMS germplasm remains limited, and the molecular mechanisms underlying fertility transition of TGMS lines are still poorly understood.

24 million years of pollination interaction between European linden flowers and bumble bees [PDF]

New Phytologist, Volume 248, Issue 4, Page 2111-2127, November 2025.
Summary Pollination is the most common insect–plant mutualism, binding them in a co‐evolutionary framework. Historic evidence of this interaction can be partly inferred from time‐calibrated molecular phylogenies of plant and insect lineages or directly from fossils.

Structural and Functional Characterization of EXPO‐Derived Extracellular Vesicles in Plants [PDF]

Advanced Science, Volume 13, Issue 14, 9 March 2026.
In this study, 3D electron tomography (ET), cryo‐ET, and immunogold transmission electron microscopy (TEM) are employed to characterize plant extracellular vesicles (EVs) under physiological conditions. EVs are classified into three distinct categories according to their size, content, and molecular‐marker profiles. Furthermore, Exo70E2‐positive medium
