Temporal and spatial expression of genes involved in DNA methylation during reproductive development of sexual and apomictic Eragrostis curvula [PDF]

, 2017
Recent reports in model plant species have highlighted a role for DNA methylation pathways in the regulation of the somatic-to-reproductive transition in the ovule, suggesting that apomixis (asexual reproduction through seeds) likely relies on RdDM ...

Pollen calendars: a guide to common airborne pollen in Andalusia

Aerobiologia, 2015
This paper presents pollen calendars for the capital cities of the eight provinces of Andalusia (south of Spain) based on the airborne pollen counts recorded in a 10-year historical database. Pollen calendars are useful in the prevention and diagnosis of hay fever, in that they enable the timing and severity of the pollen season to be clearly defined ...

Climate change and perennial crop production: Evidence of yield impact and adaptation in California

American Journal of Agricultural Economics, EarlyView.
Abstract Perennial crops are economically important. They contribute to food security, providing essential nutrients that are often lacking in annual crops, and provide additional environmental benefits compared with annual crops. Despite their importance, empirical research on the impacts of climate change and adaptation on perennial crops remains ...

Risk of injury associated with the sedative potential of second‐generation antihistamines: A nationwide retrospective cohort study

British Journal of Clinical Pharmacology, EarlyView.
Abstract Aim Individual second‐generation antihistamines may possess differential sedative potential due to the variability in central histamine receptor H1 occupancy. This study aimed to evaluate whether the sedative potential of second‐generation antihistamines is associated with the risk of injury during Japan's pollen season. Methods We conducted a
