the symbiotic effect of piriformospora indica on induced resistance against bakanae disease in rice (oryza sativa l.)

The symbiotic effect of Piriformospora indica on induced resistance against bakanae disease in rice (Oryza sativa L.)

The root endophytic fungus, Piriformospora indica, colonizes roots of a large number of plant species including Cereals and Brasicaceae. There are several reports indicating that P. indica protects roots from different path- ogens. In the present study, rice plants were pre-inoculated with P. indica and were subsequently infected with Fusarium proliferatum, as the causal agent of root rot and c...

Straighthead Disease of Rice (Oryza sativa L.) Induced by Arsenic

SSR mapping of brown planthopper resistance gene Bph9 in Kaharamana, an Indica rice (Oryza sativa L.).

The brown planthopper (BPH) is one of the most serious insects pests of rice, and the host resistance has been recognized as one of the most economic and effective measures for BPH management. In this study, we conducted a molecular-based genetic analysis of Bph9 in Kaharamana, a Sri Lanka rice variety resistant to BPH insects of East and Southeast Asia. An F2 segregating population composed of...

Population structure analysis and association mapping of blast resistance in indica rice (Oryza sativa L.) landraces.

Rice blast caused by Magnaporthe oryzae is one of the most devastating rice diseases worldwide. To understand the genetic diversity of indica landrace accessions and identify simple sequence repeat (SSR) markers that are associated with blast resistance, a population of 276 indica landraces from across the world was constructed. This population was then used to evaluate the blast-resistance phe...

Studies on improved Agrobacterium-mediated transformation in two indica rice (Oryza sativa L.)

Agrobacterium tumefaciens strain EHA 105 carrying binary vector pCAMBIA 1301 was used for transformation in two economically important highly recalcitrant indica rice cultivars HKR-46 and HKR126. High concentrations of acetosyringone in the Agrobacterium culture and co-cultivation medium proved to be indispensable for successful transformation. Embryogenic scutellar calli were used for transfor...
