OPTIMIZATION OF PARTICLE BOMBARDMENT CONDITIONS FOR RICE (Oryza sativa L.) TRANSFORMATION

Correlation Studies in Rice (Oryza sativa L.)

Seventy genotypes of rice (Oryza sativa L.) were evaluated during Kharif 2012 to study the nature and extent of correlation among yield and yield attributing characters, days to 50 per cent flowering, days to maturity, number of effective tillers per plant, plant height, panicle length, number of grains per panicle, 1000-grain weight, grain yield per plant, kernel length, kernel breadth and L/B...

Agrobacterium-mediated transformation of White Ponni, a non-basmati variety of indica rice (Oryza sativa L.)

We report successful Agrobacterium-mediated transformation of a popular rice variety White Ponni, a non-basmati indica rice (Oryza sativa L.). Scutellumderived calluses of White Ponni were transformed with Agrobacterium strain LBA4404 (pSB1) harbouring the binary vector pMKU-RF2 with rice chi11 gene. Five independent transgenic White Ponni plants were ge nerated from hygromycin-resistant callus...

The extent of linkage disequilibrium in rice (Oryza sativa L.).

Despite its status as one of the world's major crops, linkage disequilibrium (LD) patterns have not been systematically characterized across the genome of Asian rice (Oryza sativa). Such information is critical to fully exploit the genome sequence for mapping complex traits using association techniques. Here we characterize LD in five 500-kb regions of the rice genome in three major cultivated ...

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

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...
