Industrialization-driven surface ozone (O) pollution significantly impairs plant growth. This study evaluates the effectiveness of exogenous protectants [3 mg L⁻ abscisic acid (ABA), 400 mg L⁻ ethylenediurea (EDU), and 80 mg L⁻ spermidine (Spd)] on Trifolium repens subjected to O stress in open-top chambers, focusing on plant growth and dynamics of culturable endophytic fungal communities. Results indicate that O exposure adversely affects photosynthesis, reducing root biomass and altering root structure, which further impacts the ability of plant to absorb essential nutrients such as potassium (K), magnesium (Mg), and zinc (Zn).

Article Synopsis
- A variety of fungi can grow and invade mortar, which is a material used in building, but they do so in different ways.
- These fungi create calcium crystals and can even cause damage to the mortar by digging into it and changing its surface.
- Some fungi, like Aspergillus niger and Stemphylium sp., can grow deeper in less porous mortar, which can be important for understanding how these fungi affect buildings and structures.

Objective: To identify and registry the most important fungal spores trapped in our aerobiology station, as well as to report the prevalence of skin sensitization to these allergens.
Methods: The pollen counts were made according to standardized technique with a Burkard seven days spore trap, following the American Academy of Allergy, Asthma and Immunology (AAAAI) through National Allergy Bureau (NAB) recommendations. The trap was installed on the roof of Clinica SANNA, El GOLF, San Isidro, which is 20 m high, 12°5'54"S 77°3'6"W in the west-south of the Lima urban area.

Objetivo: To identify and registry the most important aeroallergens trapped at the aerobiology station in the city of Samborondon, Ecuador.
Methods: Pollen grains and fungal spore counts were performed according to the standardized technique with a Hirst-type collection equipment, Burkard spore trap for seven days, following the recommendations of the National Allergy Bureau (NAB) of the American Academy of Allergy Asthma and Immunology (AAAAI). The equipment was installed on the roof of the Universidad de Especialidades Espiritu Santo (UEES), 25 m above ground level, coordinates: 2°07 ́57 ́ ́S 79°52 ́06 ́ ́W, in the city of Samborondon.
