The 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 کاملGene 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 Lr34 multipathogen resistance gene confers resistance to anthracnose and rust in sorghum
The ability of the wheat Lr34 multipathogen resistance gene (Lr34res) to function across a wide taxonomic boundary was investigated in transgenic Sorghum bicolor. Increased resistance to sorghum rust and anthracnose disease symptoms following infection with the biotrophic pathogen Puccinia purpurea and the hemibiotroph Colletotrichum sublineolum, respectively, occurred in transgenic plants expr...
متن کاملThe Mediation Mechanism for Flood-Induced Rice Blast Field Resistance
Rice blast, an erratic niche disease incited by Magnaporthe grisea Cav., frequently limits rough rice yields and grower cultivar options in Arkansas rice production areas. Scientists poorly understand why some blast-susceptible varieties such as ‘Newbonnet’, ‘LaGrue’, ‘Mars’, and ‘Cypress’ become increasingly more blast resistant if grown in continuously flooded soil. A greenhouse depth-of-floo...
متن کاملNatural Variation at the Pi-ta Rice Blast Resistance Locus.
ABSTRACT The resistance gene Pi-ta protects rice crops against the fungal pathogen Magnaporthe grisea expressing the avirulence gene AVR-Pita in a gene-for-gene manner. Pi-ta, originally introgressed into japonica rice from indica origin, was previously isolated by positional cloning. In this study, we report the nucleotide sequence of a 5,113-base pair region containing a japonica susceptibili...
