Rice blast resistance gene,Pi54provides broad-spectrum resistance against different strains ofMagnaporthe oryzae. Understanding the cellular localization of Pi54 protein is an essential step towards deciphering its place of interaction with the cognateAvr-gene. In this study, we investigated the sub-cell...
Bacterial leaf blight (BLB) disease, caused byXanthomonas oryzaepv. oryzae (Xoo),is one of the most serious diseases in most rice growing countries due to its high epidemic potential and destructiveness to high-yielding cultivars in both temperate and tropical regions [1]. Bacterial leaf blight ...
Management of crop diseases through disease resistance is acknowledged to be the most desirable and profitable approach. In order to develop cultivars with built-in resistance, the knowledge about the methods of assessing the levels of resistance to dise
A total of 37 resistance genes against Xoo has been identified in rice. Of these, ten BLB resistance genes have been mapped on rice chromosomes, while 6 have been cloned, sequenced and characterized. Diversity analysis at the resistance gene level of this disease is scanty, and the landraces ...
The utilization of host-resistant cultivars carrying major resistance (R) genes is the most economic and efficient strategy to manage BLB disease, and which also has a neutral effect on the environment (Singh et al., 2001; Jena and Mackill, 2008). The IR62266 rice variety, which carries ...
PMQR prevalence in natural, clinical and community settings, is a priority in the combat with resistance against quinolones and other antibiotics such as β-lactams. Three types of PMQR genes have been discovered: the pentapeptide-encoding qnr genes such as qnrA17, qnrB8, qnrS18, qnrC19, ...

Many of these defenses are controlled by development- or metabolism-related genes that trigger a long lasting systemic acquired resistance (SAR) to defend the plant against a broad spectrum of pathogens. Glutamate synthase (GOGAT) is a key enzyme in the synthesis of glutamate. Glutamate is a ...
