Rice (Oryza sativa L.) is most commonly cultivated food grain crop in India as well over the world. susceptible to many destructive diseases, among them bacterial diseases reported major constrain their production which causes significant yield loss. Major affecting viz., Bacterial leaf blight (BLB) (Xanthomons oryzae pv. oryzae), streak (BLS) (Xanthomonas oryaze oryzacola) and panicle (BPB) (B...

Plants are constantly challenged by a wide range of pathogens and have therefore evolved an array of mechanisms to defend against them. In response to these defense systems, pathogens have evolved strategies to avoid recognition and suppress plant defenses (Brown and Tellier, 2011). Three recent reports dealing with the resistance of rice to Xanthomonas oryzae have added a new twist to our unde...

Formycin B, an inosine analogue, inhibits the incorporation of radioactive adenosine, uridine and thymidine, but none of formic acid, orotic acid and inorganic phosphoric acid into the cellular nucleic acid of Xanthomonas oryzae. The biochemical effects are readily reversed when formycin B is removed. Cell-free extract from the organism is entirely insensitive to formycin B in respect to phosph...

The rice XA21 receptor kinase confers robust resistance to the bacterial pathogen Xanthomonas oryzaepv. oryzae (Xoo). We developed a detached leaf infection assay to quickly and reliably measure activation of the XA21-mediated immune response using genetic markers. We used RNA sequencing of elf18 treated EFR:XA21:GFP plants to identify candidate genes that could serve as markers for XA21 activa...
