Alternaria genus is an important pathogen in plants, and their allergens are one of the most important causes of respiratory allergic diseases in Europe. Alternaria fungal spore concentrations were studied in the air of Don Benito, Plasencia and Zafra (SW Iberian Peninsula), from February 2011 to December 2014, using Hirst spore traps. Daily and ho...

Self-Incompatibility (SI) is a genetically controlled mechanism that prevents self-fertilisation and thus encourages outbreeding and genetic diversity. During pollination, most SI systems utilise cell-cell recognition to reject incompatible pollen. Mechanistically, one of the best-studied SI systems is that of Papaver rhoeas (poppy), which involves...

Self-incompatibility (SI) is used by many angiosperms to reject 'self' pollen and avoid inbreeding. In field poppy (Papaver rhoeas), SI recognition and rejection of 'self' pollen is facilitated by a female S-determinant, PrsS, and a male S-determinant, PrpS. PrsS belongs to the cysteine-rich peptide (CRP) family, whose members activate diverse sign...

Pollen tube growth is essential for plant reproduction. Their rapid extension using polarized tip growth provides an exciting system for studying this specialized type of growth. Self-Incompatibility (SI) is a genetically controlled mechanism to prevent self-fertilisation. Mechanistically, one of the best-studied SI systems is that of Papaver rhoea...

El desarrollo de redes aerobiológicas en España se ha realizado a nivel de las comunidades autónomas. En Extremadura el muestreo llevado a cabo por la Universidad de Extremadura comenzó en 1993 con la estación de Badajoz (BA). Dos localidades han tenido muestreo de forma temporal, Cáceres (CC 1996-2001) y Mérida (ME 1996-1998). En la actualidad se...

During an international campaign organized in Munich (Germany) in 2021 to test the performance of automatic pollen traps, we ran four manual Hirst-type pollen traps in parallel. All 4 Hirst-type pollen traps were set and monitored on a weekly basis for the entire campaign to 10 L/min using the same standard hand-held rotameter. Afterwards, a hand-h...

To benefit allergy patients and the medical practitioners, pollen information should be available in both a reliable and timely manner; the latter is only recently possible due to automatic monitoring. To evaluate the performance of all currently available automatic instruments, an international intercomparison campaign was jointly organised by the...

Glycosylphosphatidylinositol-anchored proteins (GPI-APs) are tethered to the outer leaflet of the plasma membrane where they function as key regulators of a plethora of biological processes in eukaryotes. Self-incompatibility (SI) plays a pivotal role regulating fertilization in higher plants through recognition and rejection of "self" pollen. Here...

En este estudio aerobiológico se analizaron las partículas de origen fúngico que se transportan de forma pasiva a través del aire. Éstas pueden ocasionar problemas de biodeterioro de documentos, objetos y edificios, problemas de salud en humanos y animales y también fitopatologías en plantas en las que se centran los objetivos de este trabajo. Las...
