Arabidopsis Fused kinase TWO-IN-ONE (TIO) controls phragmoplast expansion through its interaction with the Kinesin-12 subfamily proteins that anchor the plus ends of interdigitating microtubules in the phragmoplast midzone. Previous analyses of loss-of-function mutants and RNA interference lines revealed that TIO positively controls both somatic and gametophytic cell cytokinesis; however, knowledge of the full spectrum of TIO functions during plant development remains incomplete.

A Hypomorphic Mutant of PHD Domain Protein Male Meiocytes Death 1
TLDR
A hypomorphic mmd1/duet allele that typically shows defects in microtubule organization and cytokinesis is reported in Arabidopsis mutant male meiotic restitution 1.
Plant Kinesin-12: Localization Heterogeneity and Functional Implications
TLDR
This review aims to summarize the current knowledge on kinesin-12 in plants and shed some light onto the heterogeneous localization and domain architecture, which potentially conceals functional diversification.

Plants have unique microtubule (MT) arrays, cortical MTs, preprophase band, mitotic spindle, and phragmoplast, in the processes of evolution. These MT arrays control the directions of cell division
The Solanum chacoense Fertilization-Related Kinase 3 (ScFRK3) is involved in male and female gametophyte development
TLDR
The ScFRK3 MAPKKK is involved in a signaling cascade that regulates both male and female gamete development, and most probably act upstream of ScMKK3 and ScMPK13.
Cell cycle-regulated PLEIADE/AtMAP65-3 links membrane and microtubule dynamics during plant cytokinesis.
TLDR
Physical and genetic interactions between Transport Protein Particle II (TRAPPII) tethering factors and microtubule-associated proteins of the PLEIADE/AtMAP65 family are document and provide a conceptual framework for how membrane and micro Tubule dynamics may be coordinated with each other and with the nuclear cycle during plant cytokinesis.
Maleic hydrazide elicits global transcriptomic changes in chemically topped tobacco to influence shoot bud development.
TLDR
The findings suggest that MH affects shoot bud development in chemically topped tobacco by altering the expression of genes related to meristem development, DNA repair and recombination, cell division, and phytohormone signaling.
A major quantitative trait locus on chromosome A9, BnaPh1, controls homoeologous recombination in Brassica napus
TLDR
This study is the first to assess homoeologous recombination and map associated QTLs resulting from deviations in normal pairing in allotetraploid B. napus and suggest candidate meiotic genes that could be manipulated in order to control this important trait.
Plant speciation through chromosome instability and ploidy change: Cellular mechanisms, molecular factors and evolutionary relevance
TLDR
A comprehensive overview of somatic and meiotic defects that lead to polyploidy or structural genome changes and their relevance for plant genome evolution and speciation is provided and their putative role in boosting adaptive genome evolution in hostile environments is elaborate.
Phragmoplast microtubule dynamics – a game of zones
TLDR
Mechanisms of the midzone establishment and initiation of cell plate biogenesis; and signaling in the phragmoplast are discussed, suggesting that microtubule loss there is irreversible.

Arabidopsis Fused kinase and the Kinesin-12 subfamily constitute a signalling module required for phragmoplast expansion.
TLDR
The results support the role of TIO as a functional protein kinase that interacts with Kinesin-12 subfamily members mainly through the C-terminal ARM repeat domain, but with a contribution from the N-Terminal kinase domain.
A Divergent Cellular Role for the FUSED Kinase Family in the Plant-Specific Cytokinetic Phragmoplast
TLDR
Phenotypic analysis of tio mutants reveals an essential role for TIO in conventional modes of cytokinesis in plant meristems and during male gametogenesis, and it is demonstrated that TIO is tightly localized to the midline of the nascent phragmoplast and remains associated with the expanding phragoplast ring.
TETRASPORE encodes a kinesin required for male meiotic cytokinesis in Arabidopsis.
TLDR
The predicted TES protein includes an N-terminal domain homologous to kinesin motors and a C-terminus with little similarity to other proteins except for a small number of plant kinesins, which is likely to function as a microtubule-associated motor in pollen formation.
AtMPK4 is required for male-specific meiotic cytokinesis in Arabidopsis.
TLDR
It is reported that Arabidopsis MPK4, an MAPK that was previously described as a regulator of disease resistance, can interact with and be phosphorylated by the cytokinesis-related MAP kinase kinase, AtMKK6.
The microtubule-associated kinase-like protein RUNKEL functions in somatic and syncytial cytokinesis.
TLDR
A common role for RUK is found in both phragmoplast-based cytokinesis in somatic cells and syncytial cytokinesIS in reproductive cells, supported by ultrasound analysis of male tetrads.
Two Arabidopsis Phragmoplast-Associated Kinesins Play a Critical Role in Cytokinesis during Male Gametogenesis
TLDR
It is concluded that Kinesin-12 members serve as dynamic linkers of the plus ends of antiparallel microtubules in the phragmoplast during cytokinesis in the microspore that is essential for cell plate formation.
Arabidopsis kinesins HINKEL and TETRASPORE act redundantly to control cell plate expansion during cytokinesis in the male gametophyte.
TLDR
HIK and TES are co-expressed in microspores and developing pollen, and, through analysis of microspore and pollen development in double heterozygote mutants, the occurrence of cell plate expansion defects during cytokinesis at PMI is observed.
The tobacco MAP215/Dis1-family protein TMBP200 is required for the functional organization of microtubule arrays during male germline establishment
TLDR
Depletion of TMBP200, a tobacco homologue of MOR1/GEM1 in gametophytic microtubule-reporter plants using microspore-targeted RNA interference, induced defects in microSpore polarity, division asymmetry and cytokinesis that were associated with striking defects in phragmoplast position, orientation, and structure.
TETRASPORE is required for male meiotic cytokinesis in Arabidopsis thaliana.
TLDR
Four mutant alleles of TETRASPORE (TES), a gene essential for microsporocyte cytokinesis in Arabidopsis thaliana, are described, which reveal a gene specific to male meiosis and aid investigation of a wide range of processes in pollen development and function.
Microtubule-Associated Kinase-like Protein RUNKEL Needed for Cell Plate Expansion in Arabidopsis Cytokinesis
TLDR
The results suggest that RUK plays a regulatory, rather than catalytic, role in phragmoplast microtubule organization during cell plate expansion in cytokinesis.
