Plant Phenotyping by Vibrational Spectroscopy of Pollen

Plant traits, in the form of observable morphological, biochemical and physiological features, relate directly to the functional and reproductive success of plants in their environments. For that reason, plant phenotyping is the cornerstone of botany and all plant related studies: from agronomy and forestry to ecology and global climate research. POLLEN project has developed and standardised vibrational spectroscopy for identification and biochemical characterization of plant pollen.

Pollen and spores are abundant and widespread in all sorts of environments, from terrestrial, aquatic and atmospheric ecosystems, all the way to urban and indoor environments. Pollen and spores are the reproductive structures (microorganisms) of plants and fungi, and thus have key function during plant and fungal life cycles. In the form of microfossils they are present in all types of soil and rock sediments, and thus their identification is vital for the reconstruction of past environments and for the understanding of the causes of environmental changes. Therefore, monitoring of these microorganisms is important for management of environment, including pollution, biodiversity and climate impact on wild and cultivated communities (including agronomy and forestry). Moreover, monitoring is vital due to their, often harmful, impact on society, by causing diseases, food spoilage and material decomposition. For example, aerollergenic pollens and spores trigger respiratory diseases in susceptible individuals that are affecting 20% of European population (with the increased prevalence), causing multibillion costs of medical treatments and reduced work productivity. For the last century, palynology (the science of pollen and spores) has been limited by laborious, slow and costly methods.

POLLEN project has developed and standardised vibrational spectroscopy for identification and biochemical characterization of plant pollen. In addition to analysis of pollen, the project has established the same methodologies in analyses of plant and fungal spores. The original methodologies developed in the project have enabled objective identification and comprehensive characterisation of pollen and spores. A novel spectroscopy-based approach for screening, monitoring and analysis of these microorganisms has the potential to expand current knowledge and research, and to advance industrial and social applications by providing new insights on plants and fungi. By implementing spectroscopy-based approach, POLLEN project has created a paradigm shift that will advance palynology into new scientific and applied fields.
