No, I did not. Further, no BR1 proteins were among the top hits when
searching with the 30K superfamily consensus sequences.

The entire non-redundant protein sequence database was searched by Blast
using the movement protein consensus sequences. Yes, a few plant proteins
appeared on the list, but nothing strikingly significant.
