I will seek out a link or try to get permission to include the paper in this blog so that everyone can read it. In the meantime, here is the concluding paragraph sent to me me by two different attendees:
In conclusion, results from this study are consistent with the presence of several plant species according to cpDNA barcodes and distinct human mtDNA haplogroups. Overall DNA data were compared with historical information to verify whether the geographic areas of origin and distribution of land plant species (embryophytes) and human mitochondrial haplogroups are coherent with the proposed temporal and spatial paths of the Turin Shroud. Our experimental findings and additional clues pose a further difficulty to those who postulate a central European origin and a historical interval corresponding to the Middle Ages of the Relic.
from, as explained earlier in the paper:
… pollen grains, cell debris and other minuscule organic specimens, such as plant-derived fibers and blood-like clots found into the dusts sampled in the Turin Shroud by STURP Members. In particular, the dust particles analyzed in this study belong to different filters of the back of the Turin Shroud, also corresponding to the areas face, hands, buttocks and feet.
