Agent-Based Modeling of Pollen Competition [PDF]

open access: yes, 2018
Non-random mating in Arabidopsis Thaliana is, at least in part, due to intense competition between pollen grains to fertilize the limited number of ovules.

Wavelet Based Fractal Analysis of Airborne Pollen

open access: yes, 1998
The most abundant biological particles in the atmosphere are pollen grains and spores. Self protection of pollen allergy is possible through the information of future pollen contents in the air.

Nuclear Entanglement: New Insights Into the Role of Cytoskeleton and Nucleoskeleton in Plant Nuclear Function

open access: yesCytoskeleton, EarlyView.
ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

Automation of pollen analysis using a computer microscope : a thesis presented in partial fulfilment of the requirements for the degree of Master of Engineering in Computer Systems Engineering at Massey University [PDF]

open access: yes, 2004
The classification and counting of pollen is an important tool in the understanding of processes in agriculture, forestry, medicine and ecology. Current pollen analysis methods are manual, require expert operators, and are time consuming.

Making Two out of One: Kinesin Motors Driving Plant Cell Division

open access: yesCytoskeleton, EarlyView.
ABSTRACT The Kinesin superfamily of microtubule dependent motors is present in all eukaryotes. Not all of the subfamilies are represented in all kingdoms, and the ones that are do not always show conserved functions. Tight control of the cytoskeleton is essential for proper progression and completion of mitosis and cytokinesis, and key functions are ...

Pollen

open access: yes, 2023
When you are inhaling pollen, your body has been penetrated by a little package of plant sperm. Pollen grains are multicellular organisms that contain male sex cells, and their job is to get this sperm to the egg to facilitate fertilization. For that, they hitch a ride on insects or trust their fate to wind, water, and any other moving means, including

Effect of sucrose on in-vitro pollen germination of Gloriosa superba L. - a medicinal plant from the Garhwal Himalaya, India

open access: yesEnvironment Conservation Journal, 2017
Pollen germination and pollen tube growth are prerequisites for fertilization in seed bearing plants. The present study deals with the morphology, production, pollen-ovule ratio, and effect of sucrose on in-vitro germination of pollen grains of Gloriosa ...

A Tobacco Homolog of DCN1 is Involved in Cellular Reprogramming and in Developmental Transitions [PDF]

open access: yes, 2011
Plant proteomes show remarkable plasticity in reaction to environmental challenges and during developmental transitions. Some of this adaptability comes from ubiquitin-mediated protein destruction regulated by cullin-RING E3 ubiquitin ligases (CRLs ...
