Fibrillin protein function: the tip of the iceberg?

Trends Plant Sci. 2011 Aug;16(8):432-41. doi: 10.1016/j.tplants.2011.03.014. Epub 2011 May 14.


Fibrillins are nuclear-encoded, plastid proteins associated with chromoplast fibrils and chloroplast plastoglobules, thylakoids, photosynthetic antenna complexes, and stroma. There are 12 sub-families of fibrillins. However, only three of these sub-families have been characterized genetically or functionally. We review evidence indicating that fibrillins are involved in plastoglobule structural development, chromoplast pigment accumulation, hormonal responses, protection of the photosynthetic apparatus from photodamage, and plant resistance to a range of biotic and abiotic stresses. The area of fibrillin research has substantial growth potential and will contribute to better understanding of mechanisms of plant stress tolerance and plastid structure and function.
