Microsporogenesis and male gametogenesis are essential for the alternating life cycle of
flowering plants between diploid sporophyte and haploid gametophyte generations. Rice …

Programmed cell death is essential for the development of multicellular organisms, yet
pathways of plant programmed cell death and its regulation remain elusive. Here we report …

Anther cuticle and pollen exine act as protective envelopes for the male gametophyte or
pollen grain, but the mechanism underlying the synthesis of these lipidic polymers remains …

The Zingiberales are a tropical group of monocotyledons that includes bananas, gingers,
and their relatives. The phylogenetic relationships among the eight families currently …

Orbicules, or Ubisch bodies, are sporopollenin particles lining the inner tangential and
sometimes also the radial tapetal cell walls. They occur only in species with a secretory …

This paper critically reviews the distribution of microsporogenesis types in relation to recent
concepts in monocot systematics. Two basic types of microsporogenesis are generally …

Inaperturate pollen is widespread in the monocotyledons, includes a diverse range of forms,
and has arisen independently numerous times. Evidence for this comes from the …

The distribution of tapetal types in basal angiosperms is reviewed both from the literature
and new observations in the context of recent phylogenetic analyses. Secretory tapeta …
