(Academic Press Inc Elsevier Science, 2011-05)
Plant genotypic effects can alter insects' ability of utilizing their host plant. Alligator weed, Alternanthera philoxeroides, is a South American amphibious Amaranthaceae, which invades aquatic and terrestrial habitats. ...
Heterochronic reproductive developmental processes between diploid and tetraploid cytotypes of Paspalum rufum
(Oxford University Press, 2019-05)
BACKGROUND AND AIMS: Apomixis is an asexual reproductive mode via seeds that generate maternal clonal progenies. Although apomixis in grasses is mainly expressed at the polyploid level, some natural diploid genotypes of ...

Origins of polyploidy in Paspalum stellatum and related species (Poaceae, Panicoideae, Paspaleae) inferred from phylogenetic and cytogenetic analyses
(Oxford University Press, 2018-08)
Paspalum stellatum is widely distributed in the American continent and it is known to include diploid cytotypes (2n = 2x = 20) and polyploid cytotypes (2n = 32 and 52). It is closely related to P. eucomum, P. malmeanum and ...
