Eukaryotic development and stem cell control depend on the integration of cell positional sensing with cell cycle control and cell wall positioning, yet few factors that directly link these events are known. The DEFECTIVE KERNEL1 (DEK1) gene encoding

Sporogenesis and the evolution of thick-walled meiospores were of paramount importance in the establishment of the first life on land nearly half a billion years ago. Indeed, the first evidence of plant life on land is the sudden appearance of spores

Meiosis in bryophytes retains unusual features that provide clues to the innovation of sporogenesis in early land plants. Sporocytes are typically quadrilobed before nuclear division and the meiotic spindle is quadripolar with poles in the four futur

Fossil spores from mid-Ordovician deposits (475 million yr old) are the first indication of plants on land and predate megafossils of plants by 30-50 million yr. Sporopollenin-walled spores distinguish land plants from algae, which typically have hea

As the earliest divergent land plants, bryophytes (mosses, hornworts, and liverworts) provide insight into the evolution of the unique plant process of sporogenesis by which meiosis results in heavy walled spores. New immunohistochemical data on micr

Indirect immunofluorescence and confocal microscopy were used to study the nucleation and organization of microtubules during meiosis in two species of leafy liverworts, Cephalozia macrostachya and Telaranea longifolia. This is the first such study o

γ-Tubulin is an essential component of the microtubule organizing center (MTOC) responsible for nucleating microtubules in both plants and animals. Whereas γ-tubulin is tightly associated with centrosomes that are inheritable organelles in cells of

Sporogenesis in the hepatic Marchantia polymorpha L. provides an outstanding example of the pleiomorphic nature of the plant microtubule organizing center (MTOC). Microtubules are nucleated from γ-tubulin in MTOCs that change form during mitosis and

DNA methylation (5-methylcytosine) in mammalian genomes predominantly occurs at CpG dinucleotides, is maintained by DNA methyltransferase1 (Dnmt1), and is essential for embryo viability. The plant genome also has 5-methylcytosine at CpG dinucleotides
