Diversity and evolution of microsporogenesis in basal angiosperms and monocots

open access: yes, 2013
Le grain de pollen, gamétophyte mâle, est le produit de la méiose mâle. Il présente une structure extrêmement diversifiée chez les Angiospermes. Afin d’étudier cette diversité, nous avons centré notre étude sur le type apertural. Défini par le nombre, la

High temperature injury and auxin biosynthesis in microsporogenesis

open access: yesFrontiers in Plant Science, 2013
Plant reproductive development is more sensitive than vegetative growth to many environmental stresses. High temperature (HT) injury is becoming an increasingly serious problem due to recent global warming. In wheat, barley, and other crops, the early phase of anther development is most susceptible to HT.

Anther Ontogeny and Microsporogenesis in <i>Helianthus annuus</i> L. (Compositae)

open access: yes, 2015
In this study, anther ontogeny and microsporogenesis were analysed in Helianthus annuus L. The undifferentiated anther is ovoid-shaped and the differentiation starts with the appearance of archesporial cells. Mature anthers are tetrasporangiate.

Abnormal cytokinesis in microsporogenesis of Brachiaria humidicola (Poaceae: Paniceae). [PDF]

open access: yes, 2018
Microsporogenesis was evaluated in the Brachiaria humidicola collection of the Embrapa Beef Cattle Center, represented by 60 acessions. One acession (H121) presented an abnormal pattern of cytokinesis that had never been reported in this genus. Among 900

Cytogenics, morphology and viability of Borreria spinosa (Rubiaceae) pollen grains

open access: yesCuadernos de investigación UNED
Introduction: Borreria spinosa is a herbaceous plant considered a weed in agricultural crops, although it also has potential in apiculture. Despite its agronomic importance, its cytogenetic and palynological traits are poorly known. Objective: To do the

Effects of virus infection on microsporogenesis and seed fertility in Capsicum

open access: yes, 1959
A study of the effects of infection with mosaic and leaf roll viruses on microsporogenesis and seed fertility in three varieties of Capsicum annuum L. showed that the infected plants had the following features.

Disturbances in microsporogenesis and pollen g rain development in Gagea lutea (L.) Ker. Gaw.

open access: yes, 2006
The meiotic division of microsporocytes and pollen grain development in Gagea lutea (L.) Ker.-Gaw. (Liliaceae) with fluorescence microscope (excitation light 400 nm) was observed after squashing the anthers in DAPI solution (fluorochrom dying DNA). Up to
