Apospory - Open Access .click

Sexual Plant Reproduction, 2010
St. John's wort (Hypericum perforatum L., 2n = 4x = 32) is a medicinal plant that produces pharmaceutically important metabolites with antidepressive, anticancer and antiviral activities. It is also regarded as a serious weed in many countries. H. perforatum is furthermore an attractive model system for the study of apomixis.

Hybridity and autopolyploidy increase the expressivity of apospory in diploid Paspalum rufum [PDF]

Plant Systematics and Evolution, 2016
Paspalum rufum Nees is a perennial grass that forms a multiploid complex. natural populations are composed mainly of diploid (2n = 2x = 20) and tetraploid(2n = 4x = 40) cytotypes.

Inheritance of Apospory in Buffelgrass

Crop Science, 1994
Previous studies on inheritance of monopolar (Panicum type) apospory in the Panicoideae resulted in three widely different genetic models and mutually incompatible data sets. We report additional data for tetraploid buffelgrass [Pennisetum ciliate (L.) Link = Cenchrus ciliaris L.] and attempt to reconcile earlier studies.

Ultrastructural characterization of apospory in Panicum maximum

Sexual Plant Reproduction, 1995
The nucellar ultrastructure of apomictic Panicum maximum was analyzed during the meiocytic stage and during aposporous embryo sac formation. At pachytene the megameiocyte shows a random cell organelle distribution and sometimes only an incomplete micropylar callose wall. The chalazal nucellar cells are meristematic until the tetrad stage. They can turn
