• GENERATIVE CELL SPECIFIC 1 is essential for angiosperm fertilization.

  The double fertilization process in angiosperms is based on the delivery of a pair of sperm cells by the pollen tube (the male gametophyte), which elo…

• Defensin-like polypeptide LUREs are pollen tube attractants secreted from synergid cells.

  For more than 140 years, pollen tube guidance in flowering plants has been thought to be mediated by chemoattractants derived from target ovules. Howe…

• A cryptic algal group unveiled: a plastid biosynthesis pathway in the oyster parasite Perkinsus marinus.

  Plastids are widespread in plant and algal lineages. They are also exploited by some nonphotosynthetic protists, including malarial parasites, to supp…

• Pollen-tube guidance: beacons from the female gametophyte.

  The sperm cell of a flowering plant cannot migrate unaided and it must be transported by the pollen-tube cell before successful fertilization can occu…

• Cell cycle-regulated, microtubule-independent organelle division in Cyanidioschyzon merolae.

  Mitochondrial and chloroplast division controls the number and morphology of organelles, but how cells regulate organelle division remains to be clari…

• Division of cell nuclei, mitochondria, plastids, and microbodies mediated by mitotic spindle poles in the primitive red alga Cyanidioschyzon merolae.

  To understand the cell cycle, we must understand not only mitotic division but also organelle division cycles. Plant and animal cells contain many org…

• Review of cytological studies on cellular and molecular mechanisms of uniparental (maternal or paternal) inheritance of plastid and mitochondrial genomes induced by active digestion of organelle nuclei (nucleoids).

  In most sexual organisms, including isogamous, anisogamous and oogamous organisms, uniparental transmission is a striking and universal characteristic…

• An evolutionary puzzle: chloroplast and mitochondrial division rings.

  Consistent with their bacterial origin, chloroplasts and primitive mitochondria retain a FtsZ ring for division. However, chloroplasts and mitochondri…

• An mt(+) gamete-specific nuclease that targets mt(-) chloroplasts during sexual reproduction in C. reinhardtii.

  Although the active digestion of mating-type minus (mt-) chloroplast DNA (cpDNA) in young zygotes is considered to be the basis for the uniparental in…
