Understanding the molecular mechanism of weed adaptation to climate changes: the case of Silverleaf Nightshade (Solanum elaeagnifoglium)
In the Mediterranean, climate change is already affecting animal and plant production challenging our efforts to secure food for the region. Over the past decades, climate change has induced transformations in the weed flora of arable ecosystems in Europe. For instance, thermophile, late-emerging and certain opportunistic weeds have become more abundant in some cropping systems influencing production and reducing the areas for animal grassing.
Solanum elaeagnifoglium is a thermophilic weed, member of the Solanaceae family, devastating the rural areas in Northern Greece. In order to understand the molecular mechanisms rendering S. elaeagnifoglium so resistant to siccity and abiotic stress, we performed full sequencing of its transcriptome. This work, recently published in BMC Genomics, presents an in depth analysis of the genes involved in the production of secondary metabolites rendering the plant resistant to insects and plant pathogens.
This is one of the many genomic efforts of the Institute of Applied Biosciences to understand the biology of important organisms affecting the local economy.
