Pre-meiotic bands and novel meiotic spindle ontogeny in quadrilobed sporocytes of leafy liverworts (Jungermannidae, Bryophyta)

  title={Pre-meiotic bands and novel meiotic spindle ontogeny in quadrilobed sporocytes of leafy liverworts (Jungermannidae, Bryophyta)},
  author={Roy Curtiss Brown and Betty E. Lemmon},
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 of sporogenesis in the largest group of liverworts important as living representatives of some of the first land plant lineages. These studies show that cytoplasmic quadrilobing of pre-meiotic sporocytes into future spore domains is initiated by… CONTINUE READING
