Differential Expression Profiling Reveals Stress-Induced Cell Fate Divergence in Soybean Microspores
Plants, 2020 Stress-induced microspore embryogenesis is a widely employed method to achieve homozygosity in plant breeding programs. However, the molecular mechanisms that govern gametophyte de- and redifferentiation are understood poorly.

Water cluster triggered vitrification in HKUST‐1 MOF crystal under pressure
InfoMat, EarlyView.Water molecules in the pore centre form an oriented pentagonal water cluster via H‐bonding, which exerts a pulling effect on Cu–O(ligand) bond and induces bond cleavage. Meanwhile, the broken fragment flips into an unfavourable arrangement that prevents the rejoining of the bond, which finally causes a continuous porous MOF network in the glassy state.

Impact of Ionic Liquids on Induction of Wheat Microspore Embryogenesis and Plant Regeneration
Agronomy, 2020 Ionic liquids are novel compounds with unique chemical and physical properties. They can be received based on synthetic auxins like 2,4-dichlorophenoxyacetic acid or dicamba, which are commonly used hormones in microspore embryogenesis.

Electron microscopy‐based three‐dimensional subcellular imaging of plant male gametophyte
Journal of Integrative Plant Biology, EarlyView.The Aquilos2 Cryo‐FIB workflows provide practical routes for cryo‐electron tomography and volume imaging in plant structural biology. ABSTRACT Understanding cellular events in three dimensions (3D) is of great importance for the annotation and illustration of biological processes in a contextual way. Imaging techniques based on electron microscopy (EM),

Climate adaptation and functional constraints drive pollen evolution in Apiales
New Phytologist, EarlyView.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 making of gametes in higher plants [PDF]
, 2005 Higher plants have evolved to be one of the predominant life forms on this planet. A great deal of this evolutionary success relies in a very short gametophytic phase which underlies the sexual reproduction cycle. Sexual plant reproduction takes place in
