«While the artemisinic acid pathway in A. annua is confined to
the glandular hairs on the plant, leading to low yields of artemisinin, our COSTREL tobacco lines produce it in their chloroplasts and therefore the whole leaf,» says lead author and postdoctoral researcher Paulina Fuentes.
Cats do not appear to be affected by conformational differences of the pinnae, as seen with the Scottish fold.3 Excessive
hair in the canal, as seen in poodles and schnauzers, can also decrease ventilation and form
hair mats that retain debris and create obstructions.7 Shar - peis have stenotic canals that may be predisposed to higher humidity levels and secretions, leading to overgrowth of normal microbial inhabitants.1, 7 An increase in
glandular tissue can lead to an increase in cerumen production and debris accumulation, which seems to be more common in cocker spaniels, springer spaniels, and Labrador retrievers.1, 7
