GpaR Drives Type III Secretion and Virulence Through Direct Activation of the HrpG-HrpX Cascade in Xanthomonas oryzae pv. oryzicola. [PDF]

Mol Plant Pathol
GpaR directly activates hrpG and hrpX, triggering the HrpG–HrpX cascade to promote virulence in rice and induce the hypersensitive response in nonhost plants, revealing a key upstream regulator of type III secretion and pathogenicity in Xanthomonas oryzae pv. oryzicola. ABSTRACT Xanthomonas oryzae pv. oryzicola (Xoc), the causal agent of bacterial leaf

Large- and small-scale population structure of Xanthomonas oryzae pv. oryzicola, a bacterial pathogen of rice [PDF]

Applied and Environmental Microbiology
Xanthomonas oryzae pv. oryzicola is a pathogen of rice responsible for bacterial leaf streak, a disease that can cause up to 32% yield loss. While it was first reported a century ago in Asia, its first report in Africa was in the 1980s.

Transcriptomic analysis of rice cultivars with distinct resistance mechanisms to Xanthomonas oryzae pv. oryzicola reveals novel components and candidate genes associated with bacterial leaf streak [PDF]

Frontiers in Plant Science
Xanthomonas oryzae pv. oryzicola causes bacterial leaf streak, a rice disease that can lead to substantial yield losses. Although an xa5-based signaling pathway is known to confer resistance to this disease, alternative stable and broad-spectrum ...

Guardians or Gateways? The Intricate Relationship Between Plant Cell Walls and Pathogenic Xanthomonas. [PDF]

Mol Plant Pathol
An overview of the intricate interactions between Xanthomonas and the plant cell wall during the infection process. ABSTRACT Plants have evolved a complex cell wall (CW) providing support and protection against environmental constraints, including constant attacks from pests and pathogens.

Xanthomonas Type III Effector XopN Targets Scaffold Protein OsRACK1B to Suppress Rice Immunity. [PDF]

Mol Plant Pathol
During infection, XopN is translocated into host cells and competes with OsRap2.6 for binding to OsRACK1B. This competitive interaction interferes with the formation of the OsRACK1B–OsRap2.6 subcomplex, thereby weakening plant resistance. ABSTRACT Bacterial leaf streak (BLS), caused by Xanthomonas oryzae pv.

XocR, a LuxR solo required for virulence in Xanthomonas oryzae pv. oryzicola [PDF]

Frontiers in Cellular and Infection Microbiology, 2015
Xanthomonas oryzae pv. oryzicola (Xoc) causes bacterial leaf streak (BLS) in rice, a serious bacterial disease of rice in Asia and parts of Africa. The virulence mechanisms of Xoc are not entirely clear and control measures for BLS are poorly developed ...

A Transcription Activator-Like Effector Tal7 of Xanthomonas oryzae pv. oryzicola Activates Rice Gene Os09g29100 to Suppress Rice Immunity [PDF]

Scientific Reports, 2017
Xanthomonas oryzae pv. oryzicola (Xoc) and X. oryzae pv. oryzae (Xoo) cause bacterial leaf streak (BLS) and bacterial leaf blight (BLB) in rice, respectively. Unlike Xoo, endogenous avirulence-resistance (avr-R) gene interactions have not been identified
