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.

Article Synopsis
  • A whole-genome QTL study on tomatoes revealed 73 meta-QTL regions linked to resistance against bacterial and fungal diseases, significantly narrowing the confidence intervals (CIs) of the original QTLs.
  • The analysis examined 491 previously reported QTLs from 40 studies, leading to the identification of 29 MQTLs for bacterial resistance and 44 for fungal resistance, with CIs reduced by 4.1-fold and 6.7-fold, respectively.
  • 73 genes associated with plant defense responses were found within the MQTL regions, highlighting potential candidate genes for breeding programs focused on enhancing resistance to diseases in tomatoes.

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.

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.

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.

Bacterial wilt of dry beans (family Fabaceae) caused by the actinobacterial agent pv. is one of the most important diseases threatening edible legume production around the globe. Despite the economic losses due to the bacterial wilt disease, the pathogen has not so far been investigated for its genomic features, pathogenicity determinants, and virulence strategies.

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 .

This study provides a phylogeographic insight into the population diversity of strains causing bacterial leaf streak disease of small-grain cereals in Iran. Among the 65 bacterial strains isolated from wheat, barley, and gramineous weeds in eight Iranian provinces, multilocus sequence analysis and typing (MLSA and MLST) of four housekeeping genes (, , , and ), identified 57 strains as pv. undulosa, while eight strains were identified as pv.
