Induction of Wheat Resistance to STB by the Endophytic Fungus and .

Background: blotch (STB) caused by fungus , is one of the important wheat ( L.) diseases difficult to control because of the lack of wheat resistant cultivars. The use of biological control agents is one possible way for triggering host plant resistance to biotic and abiotic stresses.

Genetic diversity of Acidovorax oryzae in a single site in Mazandaran province, Iran.

Brown stripe, incited by Acidovorax oryzae is one of the most important and widespread diseases in rice (Oryza sativa) nurseries in Iran. Rice seedlings showing brown stripes were collected from suburb areas in southern Sari. Bacteria were isolated on plates of sorbitol neutral red agar.

Isolation, Molecular Identification, and Mycotoxin Production of Species Isolated from the Rhizosphere of Sugarcane in the South of Iran.

Knowledge of the genetic diversity detected among fungal species belonging to the genus is of key importance for explaining their important ecological role in the environment and agriculture. The current study aimed to identify species occurring in the rhizosphere of sugarcane in the South of Iran, and to investigate their mycotoxin profiles. One-hundred and twenty-five strains were isolated from the soil of eight major sugarcane-producing sites, and were molecularly identified using sequences of partial -tubulin () and partial calmodulin () genes.

Bacteria-triggered systemic immunity in barley is associated with WRKY and ETHYLENE RESPONSIVE FACTORs but not with salicylic acid.

Leaf-to-leaf systemic immune signaling known as systemic acquired resistance is poorly understood in monocotyledonous plants. Here, we characterize systemic immunity in barley (Hordeum vulgare) triggered after primary leaf infection with either Pseudomonas syringae pathovar japonica (Psj) or Xanthomonas translucens pathovar cerealis (Xtc). Both pathogens induced resistance in systemic, uninfected leaves against a subsequent challenge infection with Xtc.

Over-expression of the cell death regulator BAX inhibitor-1 in barley confers reduced or enhanced susceptibility to distinct fungal pathogens.

BAX inhibitor-1 (BI-1) is a conserved cell death regulator protein that inhibits mammalian BAX-induced cell death in yeast, animals and plants. Additionally, HvBI-1 suppresses defense responses and resistance to the powdery mildew fungus Blumeria graminis f.sp.
