Whole‐genomic DNA amplifications from individually isolated sweet sorghum microspores

Applications in Plant Sciences, Volume 10, Issue 6, November-December 2022., 2022
Abstract Premise Sorghum is a multi‐use crop, the efficient breeding of which requires the development of new genetic tools. One such tool could be the genetic assessment of free microspores, which are released just after the tetrad stage of pollen development.

Strategies of tolerance reflected in two North American maple genomes

The Plant Journal, Volume 109, Issue 6, Page 1591-1613, March 2022., 2022
SUMMARY Maples (the genus Acer) represent important and beloved forest, urban, and ornamental trees distributed throughout the Northern hemisphere. They exist in a diverse array of native ranges and distributions, across spectrums of tolerance or decline, and have varying levels of susceptibility to biotic and abiotic stress.

Hydroxyproline-O-Galactosyltransferases Synthesizing Type II Arabinogalactans Are Essential for Male Gametophytic Development in Arabidopsis

Frontiers in Plant Science, 2022
In flowering plants, male reproductive function is determined by successful development and performance of stamens, pollen grains, and pollen tubes. Despite the crucial role of highly glycosylated arabinogalactan-proteins (AGPs) in male gamete formation,

NETWORKED2‐subfamily proteins regulate the cortical actin cytoskeleton of growing pollen tubes and polarised pollen tube growth

New Phytologist, Volume 231, Issue 1, Page 152-164, July 2021., 2021
Summary We have recently characterised NET2A as a pollen‐specific actin‐binding protein that binds F‐actin at the plasma membrane of growing pollen tubes. However, the role of NET2 proteins in pollen development and fertilisation have yet to be elucidated.

Dynamics of Calcium during In vitro Microspore Embryogenesis and In vivo Microspore Development in Brassica napus and Solanum melongena

Frontiers in Plant Science, 2017
Calcium is widely known to have a role as a signaling molecule in many different processes, including stress response and activation of the embryogenic program.

Microsporogenesis and microgametogenesis of the Argentinian species ofPodocarpus(Podocarpaceae) [PDF]

Botanical Journal of the Linnean Society, 1996
Abstract The development of the microsporangium and male gametophyte of three species of Podocarpus was studied with light microscopy (LM) and the morphology of pollen with scanning and transmission electron microscopy (SEM and TEM). During early stages, the male cone is covered with coriaceous scales.

Differential Expression Profiling Reveals Stress-Induced Cell Fate Divergence in Soybean Microspores

Plants, 2020
Stress-induced microspore embryogenesis is a widely employed method to achieve homozygosity in plant breeding programs. However, the molecular mechanisms that govern gametophyte de- and redifferentiation are understood poorly.

Microsporogenesis, microgametogenesis and pollen morphology of Passiflora spp. (Passifloraceae) [PDF]

Botanical Journal of the Linnean Society, 2002
Microsporogenesis, microgametogenesis and pollen morphology of six species of genus Passiflora L. belonging to three subgenera (Passiflora, Dysosmia, Decaloba) were studied with light and scanning microscopy; P. caerulea was also examined with transmission microscopy.

Quantitative assessment of DNA replication to monitor microgametogenesis in Plasmodium berghei

Molecular and Biochemical Parasitology, 2009
Targeting the crucial step of Plasmodium transition from vertebrate host to mosquito vector is a promising approach to eliminate malaria. Uptake by the mosquito activates gametocytes within seconds, and in the case of male (micro) gametocytes leads to rapid DNA replication and the release of eight flagellated gametes.
