Pollen morphology and ultrastructure of Acalypha (Euphorbiaceae)

Acalypha wilkesiana extracts induce apoptosis by causing single strand and double strand DNA breaks

“…The genus 'Acalypha' encompasses about 450 different species (Webster, 1994;Radcliffe-Smith, 2001;Sagun et al, 2006). Acalypha wilkesiana Muell Arg belongs to the Euphorbiaceae family, or the spurge family.…”

Revision and phylogeny of <I>Acalypha</I> (<I>Euphorbiaceae</I>) in malesia

“…Acalypha is strongly supported by the chloroplast and combined datasets (Sagun 2008). Members of this clade share (also other dioecious Capitatae that were not sampled for this study) similar pollen (Sagun et al 2006) and style morphology (G. Levin, pers. obs.…”

“…With a light microscope, Acalypha pollen is quite uniform although there may be differences in the number of apertures (Sagun et al 2006). The size is generally small and the shape is spherical to oblate in equatorial view.…”

“…Pollen surface ornamentation cannot be resolved by light microscopy and appears either psilate or scabrate. However, scanning electron microscopy shows that exine ornamentation is rugulate to microrugulate or areolate with distinct scabrae localized on the margins of the muri or scattered over the pollen surface (Sagun et al 2006).…”

Pollen morphology of Chamaebuxus (DC.) Schb., Chodatia Paiva and Rhinotropis (Blake) Paiva (Polygala L., Polygalaceae)

“…Ortiz & Coutinho, 2001;Wang et al, 2003;Claxton et al, 2005;Sagun et al, 2006). Recently, pollen morphology has been used successfully to assess phylogenetic relationships between early divergent lineages of the Fabales clade (e.g.…”
