Sporophytic apomixis in polyploid Anemopaegma species (Bignoniaceae) from central Brazil
(2013-09-01)
Apomixis and polyploidy have been important in the evolution of the angiosperms, and sporophytic apomixis has been associated with polyembryony and polyploidy in tropical floras. We studied the occurrence of polyembryony ...

Sporophytic apomixis in polyembryonic Handroanthus serratifolius (Vahl) SO Grose (Bignoniaceae) characterizes the species as an agamic polyploid complex
(Springer, 2016-06-01)
Neopolyploidy has been associated with gametophytic apomixis and breakdown of gametophytic self-incompatibility. Nevertheless, Bignoniaceae presents agamic polyploid complexes with neopolyploidy associated to sporophytic ...
Mating in the pseudogamic apomictic Anemopaegma acutifolium DC: Another case of pseudo-self-compatibility in Bignoniaceae?
(2013-09-01)
Self-compatibility in apomictic pseudogamic species is considered fundamental to assure reproduction by seeds in extreme situations, making apomictic species more advantageous than sexual ones in these scenarios. Anemopaegma ...
Polyembryony increases embryo and seedling mortality but also enhances seed individual survival in Handroanthus species (Bignoniaceae)
(Elsevier Gmbh, Urban & Fischer Verlag, 2012-01-01)
Polyembryony seems to be advantageous to mother plants in detriment of their siblings which face competition since the beginning of seed development. This competition may limit the turnover of embryos into seedlings and ...
