Gene conferring resistance

In conclusion, sequence analysis may be useful for the rapid detection of STR resistance in MDR M. tuberculosis strains, which in turn could contribute to better control strategies of TB in Vietnam. Other molecular mechanisms associated with STR resistance in STR-resistant strains without mutations in the rpsL and rrs genes need to be further investigated.

Resistance to third-generation cephalosporins, often mediated by extended-spectrum beta-lactamases (ESBLs), is a considerable issue in hospital-associated infections as few drugs remain for treatment. ESBL genes are often located on large plasmids that transfer horizontally between strains and species of Enterobacteriaceae and frequently confer resistance to additional drug classes.

Fusarium head blight (FHB) is a problem of great concern in small grain cereals, especially wheat. A quantitative trait locus (QTL) for FHB resistance (FHB_SFI) located on the long arm of chromosome 2D in the spring wheat genotype Wuhan 1 is a resistance locus which has potential to improve the FHB resistance of bread wheat since it confers effective resistance to wheat breeding lines.

Antimicrobial peptides play important roles in both plant and animal defense systems. Moreover, over-expression of CaAMP1 (Capsicum annuum antimicrobial protein 1), an antimicrobial protein gene isolated from C. annuum leaves infected with Xanthomonas campestris pv. vesicatoria, confers broad-spectrum resistance to hemibiotrophic bacterial and necrotrophic fungal pathogens in Arabidopsis.

The IWGSC strategy for construction of the reference sequence of the bread wheat genome is based on first obtaining physical maps of the individual chromosomes. Our aim is to develop and use the physical map for analysis of the organization of the short arm of wheat chromosome 5B (5BS) which bears a number of agronomically important genes, including genes conferring resistance to fungal diseases.

ERECTA (ER) is a leucine-rich repeat-receptor-like kinase gene (LRR-RLK) encoding a protein isolated from Arabidopsis. Although the regulatory functions of ER genes have been widely explored in plant development and disease resistance, their roles in drought stress responses remain to be clarified.

Pseudomonas aeruginosa (PA) is an opportunistic Gram-negative bacterium that causes serious life threatening and nosocomial infections including pneumonia. PA has the ability to alter host genome to facilitate its invasion, thus increasing the virulence of the organism. Sphingosine-1- phosphate (S1P), a bioactive lipid, is known to play a key role in facilitating infection.

Cultivated peanut (Arachis hypogaea L.) is an important oil and protein crop, but it has low disease resistance; therefore, it is important to reveal the number, sequence features, function, and evolution of genes that confer resistance. Nucleotide-binding site–leucine-rich repeats (NBS–LRRs) are resistance genes that are involved in response to various pathogens.

Two highly effective genes for leaf rust resistance viz., Lr24, Lr28 were selected for pyramiding in the background of a susceptible but high yielding bread wheat variety DWR 162. The screening against most virulent pathotype of leaf rust 77-5 (121R63-1) indicated that both the genes confer a high degree of seedling resistance.

A study on effect of jasmonate on disease progression as well as induction of defensin gene (PDF1.2) was carry out to explore the effectiveness of Jasmonic acid in triggering defence within the host tissues. The disease severity and expression of PDF1.2 gene was examined after treatment containing Jasmonic acid and pathogen to two ecotypes of Arabidopsis at different time intervals. Methyl jasmonate treatment was found to be effective in decreasing the disease incidence by lowering the disease index in both susceptible (WS) and tolerant ecotype (Col). Transcripts of PDF1.
