CC   -!- FUNCTION: Seems to not be involved in heat resistance (By similarity).
CC       Unable to mediate restriction of long-distance movement of the
CC       pathogenic tobacco etch virus (TEV) without causing a hypersensitive
CC       response or inducing systemic acquired resistance. {ECO:0000250,
CC       ECO:0000269|PubMed:20478894, ECO:0000269|PubMed:22723957}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Single-pass membrane
CC       protein {ECO:0000250}. Note=Present in sieve elements. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the small heat shock protein (HSP20) family.
CC       {ECO:0000255|PROSITE-ProRule:PRU00285}.
CC   -!- CAUTION: Has been shown to be active in cv. Columbia (AC Q9M670) due to
CC       naturally occurring sequence variation in this strain. The sequence
CC       shown is from strains cv. Ct-1 and cv. Ga-0. {ECO:0000305}.
