In Vitro Live Cell Imaging Reveals Nuclear Dynamics and Role of the Cytoskeleton During Asymmetric Division of Pollen Mitosis I in Nicotiana Benthamiana

Cytoskeleton, EarlyView.
ABSTRACT Pollen is a male gametophyte of angiosperms. Following meiosis, the microspore undergoes an asymmetric division called pollen mitosis I (PMI), which produces two cells of different sizes: a large vegetative cell and a small generative cell. Polarized nuclear migration and positioning during PMI are important for successful pollen development ...

Longevity and germination of Juniperus communis L. pollen after storage

Scientific Reports, 2021
Pollen storage belongs among the most important activities associated with pollen handling. It overcomes the differences in pollen shedding and ovule receptivity during controlled pollination experiments.

Mapping the US Bridgebuilding Field: Situating Organizations in the Ecosystem of Social Change

Conflict Resolution Quarterly, EarlyView.
ABSTRACT This article explores the ecosystem of bridge‐building initiatives in the United States. Drawing on an original database of 223 organizations, interviews with 7 staff across 6 organizations, and a literature review related to bridge‐building, polarization, and collective action, we first describe the range of existing initiatives and their ...

Pollen production, viability and in vitro pollen germination of different litchi (Litchi chinensis) genotypes

The Indian Journal of Agricultural Sciences, 2018
Litchi (Litchi chinensis Sonn.) is one of the important commercial fruits of the subtropical region. Its short flowering period couple with narrow genetic base serves as the major constraints in litchi genetic improvement.

Pollen viability in Quercus robur L.

Archives of Biological Sciences, 2017
The variability of viability (germination rate and the length of pollen tubes) of fresh pedunculate oak (Quercus robur L.) pollen grains was studied in vitro on a medium containing 15% sucrose. Spatial variability was studied by sampling fresh pollen grains from a total of thirteen trees at four different sites in the area of Belgrade ...

The collision of feminisms, sexuality, and trafficking in persons in the Caribbean—A place for Kempadoo

Feminist Anthropology, EarlyView.
Abstract The existence and development of feminist scholarship and practice have been revisited by feminist anthropologists and sociologists exploring it among the gendered cultural and historical dynamics of the Caribbean. Feminist Caribbeanists’ pioneering efforts that fit within this theoretical family have challenged the Global North status quo to ...

Development and in vitro evaluation of chitosan nanoparticles encapsulating Phoenix dactylifera L. (Ajwah) seed extract with supporting in silico molecular docking analysis

Food Biomacromolecules, EarlyView.
Abstract This research describes the engineering of chitosan nanoparticles (CS NPs) via ionic gelation to encapsulate Ajwah seed extract (ASE), repurposing a plant waste product for its documented antioxidant and anticancer potential. Physicochemical analysis confirmed the formation of stable nanoparticles with hydrodynamic diameters between 152.3 and ...

Selection for persistence of endophyte‐free meadow fescue under intensive grazing versus frequent mowing

Grassland Research, EarlyView.
Cattle grazing meadow fescue pasture in remnant oak savanna near Fennimore, Wisconsin. Abstract Background Meadow fescue (Schedonorus pratensis (Huds.) P. Beauv.) is highly adapted to managed rotational grazing systems with sufficient rest periods to promote regrowth and sward longevity.

User‐Relevant Climate Indices and Associated Uncertainties From Transient Convection‐Permitting Climate Model Projections

International Journal of Climatology, EarlyView.
A transient ensemble of convection‐permitting climate simulations is used to compute bias‐corrected user‐relevant climate indices for Germany under recent and future climate conditions, both considering high spatial resolution and uncertainty estimations. For high temperature indices, a clear increase is observed, for example, for hot days and tropical
