Zusammenfassung:
The genus Pseudomonas includes pathogenic species P. syringae, which can be found
in various agricultural environments and which can affect a wide variety of plants,
causing significant economic losses when the environmental conditions for its proliferation
are optimal. Comprehensive characterizations of phytopathogenic bacteria
belonging to the genus Pseudomonas are scarce in Argentina. In this work, the tabtoxin‐
producing strain Pseudomonas S5, isolated from oat, was identified as a P. syringae
through biochemical tests such as the LOPAT test, and genetic tests such as the
analysis of the small subunit ribosomal RNA gene (16S rRNA) sequence and repetitive
elements, using BOX and ERIC primers. It was also determined that this phytopathogen
is potentially capable of infecting other crops of agricultural importance for our
region, such as soybean. This ability to infect different hosts gives it an adaptive advantage
that allows it to endure seasonal changes in the environment where it lives.
Our work contributes to the physiological classification of the phytopathogen P. syringae
S5 isolated from our region, as well as to the knowledge about its range of
potential hosts.
