Identification of NBS-LRR Resistance Gene Analogues (RGA) from Rose (IIHRR13-4) Resistant to Powdery Mildew (Podosphaera pannosa (Wallr.:Fr.) de Bary)

A barley powdery mildew resistance QTL on 7HL resides in a cluster of NBS-LRR genes

Specific Mapping of Disease Resistance Genes in Tetraploid Cut Roses

Control of fungal diseases is a major constraint of cut-rose cultivation in greenhouses and in transportation around the world. Therefore, development of resistant cultivars is a promising way to reduce the use of chemicals required for controlling the diseases. Genetic analyses and breeding for resistance, however, are hampered by the high degree of heterozygosity and the polyploid nature of c...

Identification and characterization of a NBS–LRR class resistance gene analog in Pistacia atlantica subsp. Kurdica

P. atlantica subsp. Kurdica, with the local name of Baneh, is a wild medicinal plant which grows in Kurdistan, Iran.  The identification of resistance gene analogs holds great promise for the development of resistant cultivars. A PCR approach with degenerate primers designed according to conserved NBS-LRR (nucleotide binding site-leucine rich repeat) regions of known disease-resistance (R) gene...

Isolation and characterization of NBS–LRR resistance gene analogues from mango

The nucleotide-binding site (NBS)-leucine-rich repeat (LRR) gene family is a class of R genes in plants. NBS genes play a very important role in disease defence. To further study the variation and homology of mango NBS-LRR genes, 16 resistance gene analogues (RGAs) (GenBank accession number HM446507-22) were isolated from the polymerase chain reaction fragments and sequenced by using two degene...

Characterization of a TIR-NBS-LRR gene associated with downy mildew resistance in grape.

Grapevine downy mildew, caused by Plasmopara viticola, is a devastating disease that results in considerable economic losses as well as environmental damage through the repeated application of fungicides. The nucleotide-binding site leucine-rich repeat gene family functions in plant immunoactivity against various pathogens and pests. In this study, the 5' and 3' ends of the resistance gene homo...
