“…Most importantly, a very closely linked PCR-based marker, pTA248 is available for marker-assisted selection of the gene (Ronald et al 1992). Many earlier studies have shown that through marker-assisted breeding, Xa21 can be successfully introgressed into elite rice varieties (Joseph et al 2004;Gopalakrishnan et al 2008;Sundaram et al 2008Sundaram et al , 2009Perumalsamy et al 2010;Pandey et al 2013) and into hybrid rice parental lines (Chen et al 2001;Liyong et al 2003;Basavaraj et al 2010;Hari et al 2011Hari et al , 2013.…”

DRR17A is a stable wild-abortive cytoplasmic male sterile line with medium-slender grain type. DRR17A and its maintainer line DRR17B are highly susceptible to two of the major rice diseases, bacterial blight (BB) and blast. To improve DRR17B for resistance against BB and blast, we have introgressed a major dominant gene each conferring resistance against BB (Xa21) and blast (Pi54) into CH Balachiranjeevi, S.

“…Majority of these genes give complete race-specific resistance to the pathogen. The genes have either been introgressed singly or pyramided in breeding for BLB resistance in rice [16]. Due to artificial and natural selection of BLB resistant genes, the bacterial races keep evolving.…”

Marker-assisted selection and gene pyramiding are very important breeding strategies for conferring broad spectrum and durable resistance against diseases causing yield loss in rice. One such disease causing major set backs in rice production is bacterial leaf blight (BLB) caused by the pathogen Xanthomonas oryzae pv. oryzae. Molecular markers are very essential in both markerassisted selection and pyramiding of genes, hence, many molecular marker techniques have already been developed. Presently, the most commonly used ones are DNA-based markers also known as molecular markers. The molecular markers are classified into two major categories based on the techniques used for detecting them. These are hybridization and polymerase chain reaction-based markers. Other types of markers available include the morphological (traditionally based) and biochemical (enzyme-based) markers. Host plant/varietal resistance is the most suitable means for controlling BLB disease of rice. Marker-assisted gene pyramiding has the potential to accelerate the breeding programmes and guarantee the durability of resistance conferred in the host plant. Therefore, this paper uncovers the utilization, economic importance, limitations and future prospects of marker-assisted selection and gene pyramiding for resistance to BLB disease of rice.

“…Of these R genes, nine of the R genes have been cloned and characterized (Xa1, Xa3/Xa26, xa5, xa13, Xa10, Xa21, Xa23, xa25, and Xa27) encoding different types of proteins, suggesting multiple mechanisms of R-gene-mediated Xoo resistance [7,8,10,11,13,14,[19][20][21]. Most of these genes provide complete and race-specific resistance to Xoo and have been used singly or in combination in rice breeding for BB resistance [22][23][24][25][26][27][28][29][30][31][32]. Since the bacterial races tend to evolve continually, influenced by the artificial and natural selection of genes resistant to BB, it is required to explore critically the new resistant resources to combat the evolved races.…”

Rice is an important food crop for half the world's population and has been in cultivation for over 10,000 years. During the last few decades, rice has evolved intricate relationships with associated pathogens and pests, bacterial blight (BB) being one of the most important among them. Utilization of resistant varieties with agricultural management practices is a more effective way to control BB. Of the 42 different resistance (R) genes identified to confer BB resistance, 9 have been isolated and cloned, whereas a few of the avirulence genes and a large number of candidate pathogenicity genes have been isolated from Xanthomonas oryzae pv. oryzae. The complete genome sequences of two different rice subspecies japonica and indica and three different races of BB pathogen are available. Therefore, the interaction between rice-Xoo could be deciphered and pave a way to study the molecular aspects of bacterial pathogenesis and host counter measures like innate immunity and R gene-mediated immunity. Although several of the type III effectors of Xoo have been characterized and the host targets of a few of them identified, a relatively large number of candidate effectors remain to be studied and their functional analysis may provide key for developing broad spectrum and durable resistance to BB.
