Abstract
P. ficuserectae, a new nonfluorescent, phytopathogenic pseudomonad species, is described. The bacterium produces dark brown, water-soaked spots on the leaves and stems of F. erecta Thunb., resulting in defoliation or shoot blight on severely infected plants. The colonies on nutrient agar plates are white, circular and 3-4 mm in diameter after 6 days. P. ficuserectae is similar to P. amygdali in many properties. The differences between these 2 spp. include size of colonies on agar plates, hydrolysis of Tween 80, production of H2S, utilization of ribose, raffinose, mannitol, sorbitol and malonate, and pathogenicity. The DNA base composition of the type strain of P. ficuserectae, strain L7, is 59 mol% guanine plus cytosine. The specific epithet of this new species reflects the pathogenicity of the bacterium on F. erecta Thunb.
