Starches of Oryza sativa L. japonica and Oryza sativa L. indica

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...

Genetic analysis of heterotic loci detected in a cross between indica and japonica rice (Oryza sativa L.)

The study on the genetic basis of heterosis has received significant attention in recent years. In this study, using a set of introgression lines (ILs) and corresponding testcross F(1) populations, we investigated heterotic loci (HL) associated with six yield-related traits in both Oryza sativa L. subsp. indica and japonica. A total of 41 HL were detected on the basis of mid-parent heterosis va...

Genome-wide analysis of histone modifications: H3K4me2, H3K4me3, H3K9ac, and H3K27ac in Oryza sativa L. Japonica.

While previous studies have shown that histone modifications could influence plant growth and development by regulating gene transcription, knowledge about the relationships between these modifications and gene expression is still limited. This study used chromatin immunoprecipitation followed by high-throughput sequencing (ChIP-Seq), to investigate the genome-wide distribution of four histone ...

Iron Bioavailability and Arsenic Uptake in Rice (Oryza sativa L.)

Construction of Microsatellite Linkage Map and Detection of Segregation Distortion in Indica Rice (oryza Sativa L.)

High density molecular linkage map is a prerequisite to identify the quantitative traits loci. Construction of linkage maps, using mapping populations derived from two major subspecies: indica and japonica in rice, have been reported. However, limited work was conducted in indica subspecies. Present studies focused to construct a molecular map based on indica × indica (Shaheen Basmati × Pokkali...
