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 ...
Cytogenetic and protein quantification in polyploid somatic tissue of Myrmeleon uniformis (Neuroptera, Myrmeleontidae)
(2015-04-27)
Myrmeleon unifomis Malpighian tubules cells were analyzed under two aspects: chro-matin structure and total protein quantifcation in the three larval phases (L<inf>1</inf>, L<inf>2</inf> and L<inf>3</inf>) and in adults. ...

Mechanism of micronuclei formation in polyploidizated cells of Allium cepa exposed to trifluralin herbicide
(Elsevier B.V., 2007-07-01)
The trifluralin is an agent that promotes a cellular damage due to its direct action on the microtubules. This action leads to a decontrol in the cellular division, bringing about polyploid cells. In this work, we show the ...

Sexual modulation in a polyploid Grass : a reproductive contest between environmentally inducible sexual and genetically dominant apomictic pathways
(Springer Nature editor, 2020-05-20)
In systems alternating between sexual and asexual reproduction, sex increases under unfavorable environmental conditions. In plants producing sexual and asexual (apomictic) seeds, studies on the influence of environmental ...
