Wild relatives of barley disperse their seeds at maturity by means of their brittle rachis. In cultivated barley, brittleness of the rachis was lost during domestication. Nonbrittle rachis of occidental barley lines is controlled by a single gene (btr1) on chromosome 3H. However, nonbrittle rachis of oriental barley lines is controlled by a major gene(More)
About 12,000 years ago in the Near East, humans began the transition from hunter-gathering to agriculture-based societies. Barley was a founder crop in this process, and the most important steps in its domestication were mutations in two adjacent, dominant, and complementary genes, through which grains were retained on the inflorescence at maturity,(More)
BACKGROUND CONTEXT Although the influence of genetics on the process of disc degeneration is well recognized, in recently published studies, there is a wide variation in the race and selection criteria for such study populations. More importantly, the radiographic features of disc degeneration that are selected to represent the disc degeneration phenotype(More)
Finger millet (Eleusine coracana L.) is a hardy cereal known for its superior level of tolerance against drought, salinity, diseases and its nutritional properties. In this study, attempts were made to unravel the physiological and molecular basis of salinity tolerance in two contrasting finger millet genotypes viz., CO 12 and Trichy 1. Physiological(More)
MITE, TRIM and SINEs are miniature form transposable elements (mTEs) that are ubiquitous and dispersed throughout entire plant genomes. Tens of thousands of members cause insertion polymorphism at both the inter- and intra- species level. Therefore, mTEs are valuable targets and resources for development of markers that can be utilized for breeding, genetic(More)
Paithumbase is an established database for identifying the phenotypic variations of the mungbean germplasm accessions preserved in the National Pulses Research Centre, Tamil Nadu Agricultural University. This database provides information on both quantitative and qualitative traits of the mungbean germplasm. The database architecture was built with a GUI(More)
The genetic divergence among 105 indigenous maize germplasms was assessed by employing Mahalanobis D 2 analysis based on four characteristics viz., plant height, cob height, cob length and number of kernel rows per cob. The genotypes were grouped into four clusters. Cluster IV was the largest with 53 genotypes followed by cluster II with 32 genotypes. The(More)
PURPOSE Although the exact mechanisms that lead to degenerative disc disease (DDD) are not well understood, a significant genetic influence has been found. Focusing on DDD that occurs in young adults can be valuable in determining the exact role of genetic predisposition to DDD. METHODS Patients (<40 years) with lumbar disc degeneration were evaluated(More)
‘Kavuni’ a traditional brownish black rice variety is known for its anti-diabetic properties and is grown under limited areas of Tamil Nadu, India. The present study was aimed at profiling the nutritional and therapeutic values of Kavuni grains in comparison with three other popularly eaten white rice varieties of Tamil Nadu viz., CO 50, IR64 and White(More)
