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.

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.

High Temperature Has Negative Impact on Pollen Development in Chili Pepper (Capsicum annuum L.) cv. Tanjung-2

Jurnal Ilmu Pertanian Indonesia, 2020
The development of male reproductive organ in plants is seriously affected by the adverse abiotic stresses. In this study, we investigated pollen development, particularly at microsporogenesis and micro gametogenesis stages of chili pepper (Capsicum ...

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.

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.

The male germ unit association is independently regulated of GUM in Arabidopsis thaliana. [PDF]

Plant Direct
Abstract Cytoplasmic projections (CPs) formed by the generative and sperm cells link the male gametes with the vegetative cell (VC) nucleus, which are required to build the male germ unit (MGU) assemblage in the angiosperm pollen grain. As molecular and genetic controls underlying CP development and formation of the MGU are unknown, it was hypothesized

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.

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.

Scanning and transmission electron microscopy ofEimeria maximamicrogametogenesis

Parasitology, 1981
SUMMARYThe structure and development of microgametocytes ofEimeria maximafrom chicks killed during the 6th day of infection were examined using transmission and scanning electron microscopy. Initially, nucleoli disappear and the surface of the microgametocyte invaginates.
