Making Two out of One: Kinesin Motors Driving Plant Cell Division

Cytoskeleton, Volume 83, Issue 6, Page 384-393, June 2026.
ABSTRACT The Kinesin superfamily of microtubule dependent motors is present in all eukaryotes. Not all of the subfamilies are represented in all kingdoms, and the ones that are do not always show conserved functions. Tight control of the cytoskeleton is essential for proper progression and completion of mitosis and cytokinesis, and key functions are ...

3H-thymidyne incorporation into the microspores and pollen grains nuclei in excised Tradescantia stamens

Acta Societatis Botanicorum Poloniae, 2015
The development of microspores and pollen grains lasts in Tradescantia bracteata in vivo from the tetrad stage to pollen shedding about 14 days. This including 7 days of the microspore life cycle. In stamens excised and placed on a medium the microspores

Generative Cell Division, but Not Early Nuclear Reorganization, Requires Transcriptional Reactivation During Pollen Tube Growth

Plant Direct, Volume 10, Issue 6, June 2026.
ABSTRACT Bicellular pollen often enters a desiccated state wherein development is temporarily arrested, enabling long‐term survival while maintaining the capacity for rapid activation upon hydration. Although the generative cell in mature pollen of Lilium species is known to have completed DNA replication, its precise cell‐cycle status and the ...

Comparison of six different methods to calculate cell densities

Plant Methods, 2018
Background For in vitro culture of plant and animal cells, one of the critical steps is to adjust the initial cell density. A typical example of this is isolated microspore culture, where specific cell densities have been determined for different species.

Advances in gene cloning and functional genomics approaches for wheat (Triticum aestivum L.) improvement

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Wheat (Triticum aestivum L.) is a globally important cereal crop which provides ∼20% calories in human diet. Identifying genes and elucidating their functions is still challenging in wheat due to its large genome (∼16 Gb) with significant amount of repetitive elements.

Phospholipase C is a novel regulator at the early stages of microspore embryogenesis in Nicotiana tabacum

Plant Signaling & Behavior, 2022
Microspore transfers the developmental fate into embryogenesis in vitro regulated by determinant factors of stress-induced. However, the key regulators of microspore embryogenesis (ME) are still largely undiscovered to reveal the mechanism of cell fate ...

Systemic Delivery of Functional Proteins Into Plants Using an Engineered Membrane Translocation Domain

Plant Biotechnology Journal, Volume 24, Issue 6, Page 3939-3952, June 2026.
ABSTRACT Protein‐based biopesticides and biostimulants are critical for the future of sustainable agriculture, yet their utility is severely limited by inefficient delivery into plant cells. Traditional cell‐penetrating peptides enable protein uptake but lack the efficiency, systemic activity and scalability required for crop production.

The Rice Cis‐Natural Antisense Transcript NAT1850 of Pri‐miR1850 Negatively Regulates Cold Tolerance by Repressing NPR3

Plant Biotechnology Journal, Volume 24, Issue 6, Page 3969-3988, June 2026.
ABSTRACT Natural antisense transcripts (NATs) correspond to nearly 60% of annotated rice loci, however their functions are largely unknown. In this study, we characterise a rice cis‐NAT (NAT1850) that completely overlaps with a rice‐specific primary miRNA, pri‐miR1850.

In Vivo Propagation of Root Explants of the Dandelion Species Taraxacum kok‐saghyz, Taraxacum officinale and Their Interspecific Hybrids

Plant Breeding, Volume 145, Issue 3, Page 610-624, June 2026.
ABSTRACT The dandelion species Taraxacum kok‐saghyz is a promising new crop for natural rubber production and is currently in the early stages of the breeding process. To support these efforts, the multiplication and conservation of defined genotypes are crucial.

Electron microscopy‐based three‐dimensional subcellular imaging of plant male gametophyte

Journal of Integrative Plant Biology, Volume 68, Issue 5, Page 1290-1314, May 2026.
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),
