Complete Genome Sequence of an N-Acyl Homoserine Lactone Producer, Breoghania sp. Strain L-A4, Isolated from Rhizosphere of Phragmites australis in a Coastal Wetland.

The Breoghania sp. strain L-A4 was isolated from the rhizosphere of Phragmites australis in the Qinhaungdao coastal wetland in China. Here, we present the complete genome sequence of strain L-A4, which consists of a chromosome of 5,029,620 bp with a G+C content of 64.53% and 4,964 coding DNA sequences. This strain was the first detected to produce N-acyl homoserine lactone (AHL) signals in a member of this genus.
