From the Research
The common genera under the tribe Erwinieae include Erwinia, Pantoea, and Tatumella, with Erwinia being the most well-known genus in this tribe, containing important plant pathogens like Erwinia amylovora. These genera are classified within the family Enterobacteriaceae and share similar biochemical and genetic characteristics, such as being gram-negative, rod-shaped bacteria that are typically motile and facultatively anaerobic 1.
Key Characteristics of Erwinieae Genera
- Erwinia is the most well-known genus, containing important plant pathogens like Erwinia amylovora, which causes fire blight in apple and pear trees 2.
- Pantoea is another significant genus that includes both plant pathogens and beneficial species, with Pantoea agglomerans being a notable example that can be both beneficial as a biocontrol agent and occasionally pathogenic 3.
- Tatumella is a less common genus but still recognized within Erwinieae, and these genera are important in agriculture due to their ability to cause diseases in various crops, though some species have been developed as biological control agents against other plant pathogens 4.
Importance in Agriculture
Their importance in agriculture stems from their ability to cause diseases in various crops, though some species have been developed as biological control agents against other plant pathogens 5.
Recent Findings
Recent studies have provided novel insights into the phylogenetic arrangement, plasmid diversity, and streptomycin resistance of Erwinia amylovora, highlighting the complexity and diversity of this genus 1.
