Two TAL Effectors of Xanthomonas citri pv. malvacearum Induce Water Soaking by Activating GhSWEET14 Genes in Cotton.

Bacterial blight of cotton (BBC) caused by Xanthomonas citri pv. malvacearum (Xcm) is an important and destructive disease affecting cotton plants. Transcription activator-like effectors (TALEs) released by the pathogen regulate cotton resistance to the susceptibility.

Constructed Rice Tracers Identify the Major Virulent Transcription Activator-Like Effectors of the Bacterial Leaf Blight Pathogen.

Xanthomonas oryzae pv. oryzae (Xoo) injects major transcription activator-like effectors (TALEs) into plant cells to activate susceptibility (S) genes for promoting bacterial leaf blight in rice. Numerous resistance (R) genes have been used to construct differential cultivars of rice to identify races of Xoo, but the S genes were rarely considered.

Comparative Transcriptomic Analysis of Wheat Cultivars in Response to pv. and Its T2SS, T3SS, and TALEs Deficient Strains.

pv. causes bacterial leaf streak disease on small grain cereals. Type II and III secretion systems (T2SS and T3SS) play a pivotal role in the pathogenicity of the bacterium, while no data are available on the transcriptomic profile of wheat cultivars infected with either wild type (WT) or mutants of the pathogen.

Detection and Diagnosis of Bacterial Leaf Streak on Small Grain Cereals: From Laboratory to Field.

Bacterial leaf streak of small-grain cereals is an economically important disease of wheat and barley crops. The disease occurs in many countries across the globe, with particular importance in regions characterized by high precipitation or areas in which sprinkler irrigation is used. Three genetically distinct lineages of the Gram-negative bacterium ( pv.

A transcription activator-like effector is trapped in nonhost plants for immunity.

pv. (), the causal agent of bacterial leaf blight in rice, delivers transcription activator-like effector (TALE) proteins into host cells to activate susceptibility or resistance () genes that promote disease or immunity, respectively. Nonhost plants serve as potential reservoirs of genes; consequently, nonhost genes may trap TALEs to trigger an immune response.

Genomics-Enabled Novel Insight Into the Pathovar-Specific Population Structure of the Bacterial Leaf Streak Pathogen in Small Grain Cereals.

The Gram-negative bacterium infects a wide range of gramineous plants with a notable impact on small grain cereals. However, genomics-informed intra-species population structure and virulence repertories of the pathogen have rarely been investigated. In this study, the complete genome sequences of seven strains representing an entire set of genetic diversity of two pathovars pv.

TALE-triggered and iTALE-suppressed Xa1-mediated resistance to bacterial blight is independent of rice transcription factor subunits OsTFIIAγ1 or OsTFIIAγ5.

Xa1-mediated resistance to rice bacterial blight, caused by Xanthomonas oryzae pv. oryzae (Xoo), is triggered by transcription activator-like effectors (TALEs) and suppressed by interfering TALEs (iTALEs). TALEs interact with the rice transcription factor OsTFIIAγ1 or OsTFIIAγ5 (Xa5) to activate expression of target resistance and/or susceptibility genes.

Identification of a virulence tal gene in the cotton pathogen, Xanthomonas citri pv. malvacearum strain Xss-V-18.

Background: Bacterial blight of cotton (BBC), which is caused by the bacterium Xanthomonas citri pv. malvacearum (Xcm), is a destructive disease in cotton. Transcription activator-like effectors (TALEs), encoded by tal-genes, play critical roles in the pathogenesis of xanthomonads.

Transcription Activator-Like Effectors Diversity in Iranian Strains of .

Bacterial leaf streak caused by different pathovars of is the most important seedborne bacterial disease of small grain cereals. However, variations in the virulence-associated genomic areas of the pathogen remain uninvestigated. In this study, the diversity of transcription activator-like effectors (TALE) was investigated using the Southern blotting of HIdigested genomic DNAs in the Iranian strains of .

Tal1 in pv. Contributes to Virulence in Bacterial Leaf Streak of Wheat.

pv. () causes bacterial leaf streak (BLS) of important cereal crops, including wheat () and barley (). Transcription activator-like effectors (TALEs) play vital roles in many plant diseases caused by spp.
