Spatiotemporal regulation of anther's tapetum degeneration paved the way for a reversible male sterility system in cotton. [PDF]

open access: yesPlant Biotechnol J
Summary Male sterility is an important agronomical trait in self‐pollinating plants for producing cost‐effective F1 hybrids to harness the heterosis. Still, large‐scale development and maintenance of male sterile lines and restoring fertility in F1 hybrids pose significant challenges in plant hybrid breeding.

Embryology of Swainsona formosa (Fabaceae): Anther and Ovule Development

open access: yesHayati Journal of Biosciences, 2005
Our study showed that floral morphology and anatomy in Swainsona formosa were typical of leguminous flower. The anthers were found to be tetrasporangiate, with a 3-layered wall below the epidermis. The wall was comprised of a layer of endothecium, middle

PsEND1 Is a Key Player in Pea Pollen Development Through the Modulation of Redox Homeostasis

open access: yesFrontiers in Plant Science, 2021
Redox homeostasis has been linked to proper anther and pollen development. Accordingly, plant cells have developed several Reactive Oxygen Species (ROS)-scavenging mechanisms to maintain the redox balance.

Anther development and formation of dehiscence pore in Rhododendron × pulchrum

open access: yesGuangxi Zhiwu
Flowers of Rhododendron have unique poricidal dehiscence anther, but the formation of the dehiscence pore and the mechanism of pollen releasing are not fully known.

Transcription factor MYB26 is key to spatial specificity in anther secondary thickening formation [PDF]

open access: yes, 2017
Successful fertilization relies on the production and effective release of viable pollen. Failure of anther opening (dehiscence), results in male sterility, although the pollen may be fully functional.

On the Reproductive Potential in Primula veris L. (Primulaceae): Embryological Features, Pollen and Seed Viability, Genetic Diversity

open access: yesPlants, 2021
Primula veris (Primulaceae) is a valuable medicinal plant. The main characteristics for assessing the reproductive potential (embryological features; mode of reproduction; pollen and seed viability) and the genetic diversity of populations of the species

Development of the pollen in the antarctic flowering plant Colobanthus quitensis (Kunth) Bartl.

open access: yesActa Agrobotanica, 2012
Colobanthus quitensis (Kunth) Bartl. produced two types very small bisexual fl owers. In the Antarctic natural conditions chasmogamic and cleistogamic fl owers most often form fi ve stamina with short fi laments.

Histological characterization of anther structure in Tetep-cytoplasmic male sterility and fine mapping of restorer-of-fertility gene in rice.

open access: yesPLoS ONE, 2022
Cytoplasmic male sterility (CMS) is a maternally inherited trait that inhibits plants from producing or releasing viable pollen. CMS is caused by mitochondrial-nuclear interaction, and can be rescued by introducing functional nuclear restorer-of ...

Microsporogenesis, microgametogenesis, and pollen grain morphology of Fouquieria fasciculata (Fouquieriaceae, Ericales)

open access: yesBotan‪ical Sciences, 2023
Background: Embryology of the male reproductive structures in Fouquieriaceae has been poorly studied. The ontogeny of the anther wall, microsporogenesis, microgametogenesis, and pollen morphology were described in detail for Fouquieria fasciculata ...
