Unravelling the ambiguous reproductive biology of Paspalum malacophyllum: a decades old story clarified
(Springer, 2015-08-22)
In a recent manuscript published by our group we analyzed the reproductive biology of the grass Paspalum malacophyllum by using traditional embryological techniques combined with current cytological and molecular methods. ...
Embryology and fertility of the natural tetraploid Lessingianthus plantaginoides (Asteraceae, Vernonieae): taxonomic implications
(Instituto de Pesquisas Jardim Botânico do Rio de Janeiro, 2021-10)
Lessingianthus plantaginoides (Vernonieae, Asteraceae) is a small natural tetraploid shrub that inhabits rocky highlands from South America. The population studied inhabits and covers an extensive region of a private reserve ...
Embryology in Helosis cayennensis (Balanophoraceae): Structure of Female Flowers, Fruit, Endosperm and Embryo
(MDPI, 2019-03)
Helosis cayennensis (Balanophoraceae s.str.) is a holoparasite characterised by aberrant vegetative bodies and tiny, reduced unisexual flowers. Here, we analysed the development of female flowers to elucidate their ...

Sexual modulation in a polyploid grass: a reproductive contest between environmentally inducible sexual and genetically dominant apomictic pathways
(Nature Publishing Group, 2020-05)
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 ...

Apospory followed by sterility in a hypotriploid hybrid (2x X 4x) of Paspalum
(Univ Florence Botany Inst, 2004-12)
A self-incompatible diploid plant (2n = 2x = 20) of Paspalum limbatum grown in a field nursery surrounded by tetraploid accessions of several Paspalum species produced a hypotriploid descendant (2n-1 = 3x = 29). Molecular ...
A molecular map of the apomixis-control locus in Paspalum procurrens and its comparative analysis with other species of Paspalum
(Springer, 2011-10)
Since apomixis was first mapped in Paspalum, the absence of recombination that characterizes the related locus appeared to be the most difficult bottleneck to overcome for the dissection of the genetic determinants that ...
Reproductive biology of the native forage grass Trichloris crinita (Poaceae, Chloridoideae)
(2017-05)
Trichloris crinita is a perennial forage grass species native to arid regions of the American continent. Due to its extensive area of distribution, good forage quality and resistance to drought and grazing, this species ...
