Gene pyramiding enhances durable blast disease resistance in rice
Effective control of blast, a devastating fungal disease of rice, would increase and stabilize worldwide food production. Resistance mediated by quantitative trait loci (QTLs), which usually have smaller individual effects than R-genes but confer broad-spectrum or non-race-specific resistance, is a promising alternative to less durable race-specific resistance for crop improvement, yet evidence...
متن کاملThe wheat durable, multipathogen resistance gene Lr34 confers partial blast resistance in rice.
The wheat gene Lr34 confers durable and partial field resistance against the obligate biotrophic, pathogenic rust fungi and powdery mildew in adult wheat plants. The resistant Lr34 allele evolved after wheat domestication through two gain-of-function mutations in an ATP-binding cassette transporter gene. An Lr34-like fungal disease resistance with a similar broad-spectrum specificity and durabi...
متن کاملSmall RNAs and Gene Network in a Durable Disease Resistance Gene—Mediated Defense Responses in Rice
Accumulating data have suggested that small RNAs (sRNAs) have important functions in plant responses to pathogen invasion. However, it is largely unknown whether and how sRNAs are involved in the regulation of rice responses to the invasion of Xanthomonas oryzae pv. oryzae (Xoo), which causes bacterial blight, the most devastating bacterial disease of rice worldwide. We performed simultaneous g...
متن کاملDevelopment of Dominant Rice Blast Pi-ta Resistance Gene Markers
genotypes can be easily identified (Huang et al., 1997; Hittalmani et al., 2000). A PCR-based Pi-ta gene marker Incorporation of resistance genes into existing rice (Oryza sativa is useful in marker-assisted selection breeding since it L.) cultivars is a powerful strategy and is commonly applied in breeding rice resistance to blast disease [caused by Pyricularia grisea Sacc. is the part of resi...
متن کاملNatural variation of rice blast resistance gene Pi-d2.
Studying natural variation in rice resistance genes of cultivated and wild rice relatives can predict resistance stability to rice blast fungus. In the present study, the protein coding regions of the rice R gene Pi-d2 in 35 rice accessions, including Oryza sativa L. subsp. indica Kato (Aus), indica (IND), temperate japonica (TEJ), tropical japonica (TRJ), aromatic (ARO); subgroups of Oryza sat...
