Evidence of pseudomonad pollen formation in Hypolytrum (Mapanioideae, Cyperaceae)
(CSIRO Publishing, 2010-01-01)
Cyperaceae are characterised by typical simultaneous microsporogenesis that results in the formation of pseudomonad pollen. Morphological studies indicate the occurrence of a distinct pollen type in Mapanioideae, the ...

Understanding male sterility in Miconia species (Melastomataceae): a morphological approach
(CSIRO PUBLISHINGCOLLINGWOOD, 2012)
Pollen abortion occurs in virtually all species and often does not prejudice reproductive success. However, large numbers of abnormal pollen grains are characteristic of some groups. Among them is Miconia, in which partial ...
Pollen development and anther morphology in 14 species of Rhamnaceae

Microsporogenesis, microgametogenesis, and anther structure of 14 species belonging to Rhamneae (Rhamnoids clade), Paliureae, Pomaderreae, Colletieae, and Gouanieae (Ziziphoids clade) of the Rhamnaceae family were analyzed ...
Ontogênese da antera, microsporogênese e microgametogênese de Dyckia strehliana H. Büneker & R. Pontes (bromeliaceae)
(Universidade Federal de Santa MariaBrasilCiências BiológicasUFSMPrograma de Pós-Graduação em AgrobiologiaCentro de Ciências Naturais e Exatas, 2021-03-26)
Many species of angiosperms are considered rheophytes, that is, they develop in the
banks of streams and fast-flowing rivers and are subject to the action of frequent floods,
as is the case of Dyckia strehliana ...
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 ...
Desenvolvimento de anteras em espécies de clados basais de Malpighiaceae
(Universidade Federal de Minas GeraisBrasilICB - DEPARTAMENTO DE BOTÂNICAPrograma de Pós-Graduação em Biologia VegetalUFMG, 2022-08-29)
Malpighiaceae comprises about 1,300 tropical species, distributed in 78 genera. The
family is proven monophyletic. However, many of its intrafamilial relationships have not
been elucidated, so its lineages are treated ...
