Identifying Urban Sources as Cause of Elevated Grass Pollen Concentrations using GIS and Remote Sensing [PDF]

, 2013
We examine here the hypothesis that during flowering, the grass pollen concentrations at a specific site reflect the distribution of grass pollen sources within a few kilometres of this site.We perform this analysis on data from a measurement campaign in

The connection of pollen concentrations and crowd-sourced symptom data: new insights from daily and seasonal symptom load index data from 2013 to 2017 in Vienna

World Allergy Organization Journal, 2018
Background Online pollen diaries and mobile applications nowadays allow easy and fast documentation of pollen allergy symptoms. Such crowd-sourced symptom data provides insights into the development and the onset of a pollen allergy.

Pollen Sporoplasts: Dissolution of Pollen Walls [PDF]

Plant Physiology, 1985
4-Methylmorpholine N-oxide monohydrate (MMNO.H(2)O), a potent solvent for polysaccharides, is an effective vehicle for release of membrane-enclosed male gametophytes (sporoplasts) from spore walls. This release occurs in minutes when pollen (Lilium longiflorum Thunb.) is suspended in a melt of MMNO.H(2)O at 75 degrees C. Continued heating at 75 degrees

Impact of homogenization and protein extraction conditions on the obtained tobacco pollen proteomic patterns

Biologia Plantarum, 2011
Mature pollen grain represents a highly desiccated structure with an extremely tough cell wall. Thanks to it, it resists common proteomic protocols. Instead, a robust homogenization has to be performed since proteins are needed to burst out of the cell ...

Understanding emissions of ammonia from buildings and the application of fertilizers: an example from Poland [PDF]

Biogeosciences, 2015
A Europe-wide dynamic ammonia (NH3) emissions model has been applied for one of the large agricultural countries in Europe, and its sensitivity on the distribution of emissions among different agricultural functions was analyzed by comparing with ...

Proteases with caspase 3-like activity participate in cell death during stress-induced microspore embryogenesis of Brassica napus

The EuroBiotech Journal, 2019
Microspore embryogenesis is a model system of plant cell reprogramming, totipotency acquisition, stress response and embryogenesis initiation. This in vitro system constitutes an important biotechnological tool for haploid and doubled-haploid plant ...

Pectin De-methylesterification and AGP Increase Promote Cell Wall Remodeling and Are Required During Somatic Embryogenesis of Quercus suber

Frontiers in Plant Science, 2019
Somatic embryogenesis is a reliable system for in vitro plant regeneration, with biotechnological applications in trees, but the regulating mechanisms are largely unknown.

Pollen characterisation of Maltese honey [PDF]

, 2013
In 2004 and 2005, pollen characterisation of 35 samples of honey collected from the islands of Malta and Gozo, was carried out with the aim to identify the botanical origin of honey produced on these islands.
