PEK14: A Kinesin‐4 Necessary for Male‐Derived Fertility in Arabidopsis thaliana

Cytoskeleton, Volume 83, Issue 6, Page 337-353, June 2026.
ABSTRACT Of the 61 kinesins annotated in Arabidopsis thaliana , many are still without assigned function. Here, we have screened an insertional mutant library of Arabidopsis pollen‐expressed kinesins for fertility defects. Insertional mutants for three kinesins showed a significant reduction in seed set.

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 ...

In Vitro Live Cell Imaging Reveals Nuclear Dynamics and Role of the Cytoskeleton During Asymmetric Division of Pollen Mitosis I in Nicotiana Benthamiana

Cytoskeleton, Volume 83, Issue 6, Page 394-406, June 2026.
ABSTRACT Pollen is a male gametophyte of angiosperms. Following meiosis, the microspore undergoes an asymmetric division called pollen mitosis I (PMI), which produces two cells of different sizes: a large vegetative cell and a small generative cell. Polarized nuclear migration and positioning during PMI are important for successful pollen development ...

Fin1-PP1 Helps Clear Spindle Assembly Checkpoint Protein Bub1 from Kinetochores in Anaphase

Cell Reports, 2016
Summary: The spindle assembly checkpoint (SAC) monitors chromosome attachment defects, and the assembly of SAC proteins at kinetochores is essential for its activation, but the SAC disassembly process remains unknown.

Whose end is destruction: cell division and the anaphase-promoting complex.

Genes & Development, 1999
Cell proliferation depends on the duplication of chromosomes followed by the segregation of duplicates (sister chromatids) to opposite poles of the cell prior to cell division (cytokinesis).

Evolutionary Patterns of the Genes Involved in the Integrity and Segregation of Chromosomes in Sawflies (Hymenoptera: Symphyta)

Ecology and Evolution, Volume 16, Issue 6, June 2026.
This study identifies and characterizes the genes encoding cohesin and condensin complexes across Symphytan superfamilies, revealing their structural and functional roles with conserved motifs in maintaining genome stability. Phylogenetic analyses indicate that SMC genes originated from ancient duplication events, with notable gene loss (e.g., CAPG2 ...

Chiasmata promote monopolar attachment of sister chromatids and their co-segregation toward the proper pole during meiosis I.

PLoS Genetics, 2011
The chiasma is a structure that forms between a pair of homologous chromosomes by crossover recombination and physically links the homologous chromosomes during meiosis. Chiasmata are essential for the attachment of the homologous chromosomes to opposite

The checkpoint protein MAD2 and the mitotic regulator CDC20 form a ternary complex with the anaphase-promoting complex to control anaphase initiation.

Genes & Development, 1998
The spindle assembly checkpoint mechanism delays anaphase initiation until all chromosomes are aligned at the metaphase plate. Activation of the anaphase-promoting complex (APC) by binding of CDC20 and CDH1 is required for exit from mitosis, and APC has ...

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 ...

Pedunculoside Inhibits Hepatocellular Carcinoma Progression by Activating the MAPK Signaling Pathway Through Targeting and Suppressing CDK4

Phytotherapy Research, Volume 40, Issue 6, Page 3171-3189, June 2026.
Pedunculoside targets and suppresses CDK4; consequently, it activates the MAPK pathway and inhibits hepatocellular carcinoma progression. ABSTRACT Hepatocellular carcinoma (HCC) remains a major challenge in cancer prevention and treatment, highlighting the urgent need for effective and low‐toxicity anti‐HCC therapies. Recently, CDK4‐targeted inhibitors
