Bacterial Leaf Streak Diseases of Plants: Symptom Convergence in Monocot Plants by Distant Pathogenic Species.

Bacterial leaf streak (BLS) is a disease of monocot plants caused by on small grains, on maize and sorghum, and on rice. These three pathogens cause remarkably similar symptomology in their host plants. Despite causing similar symptoms, BLS pathogens are dispersed throughout the larger phylogeny.

Current Understanding of the History, Global Spread, Ecology, Evolution, and Management of the Corn Bacterial Leaf Streak Pathogen, pv. .

Bacterial leaf streak of corn, caused by pv. , has been present in South Africa for over 70 years, but is an emerging disease of corn in North and South America. The only scientific information pertaining to this disease on corn came from work done in South Africa, which primarily investigated host range on other African crops, such as sugarcane and banana.

Genomic Acquisitions in Emerging Populations of pv. Infecting Corn in the United States and Argentina.

pv. is an emerging bacterial plant pathogen that causes bacterial leaf streak on corn. First described in South Africa in 1949, reports of this pathogen have greatly increased in the past years in South America and in the United States.

The endonuclease domain of Bacillus subtilis MutL is functionally asymmetric.

DNA mismatch repair is an evolutionarily conserved repair pathway that corrects replication errors. In most prokaryotes and all eukaryotes, the mismatch repair protein MutL is a sequence-unspecific endonuclease that nicks the newly synthesized strand and marks it for repair. Although the sequence of the endonuclease domain of MutL is not conserved, eukaryotic MutLα and prokaryotic MutL share four conserved motifs that define the endonuclease site of the protein.
