Markov segmentation is a method of identifying compositionally different subsequences in a given symbolic sequence. We have applied this technique to the DNA sequence of the human X chromosome to analyze its compositional structure. The human X chromosome is known to have acquired DNA through distinct evolutionary events and is believed to be composed of(More)
BACKGROUND Several tools are available to identify miRNAs from deep-sequencing data, however, only a few of them, like miRDeep, can identify novel miRNAs and are also available as a standalone application. Given the difference between plant and animal miRNAs, particularly in terms of distribution of hairpin length and the nature of complementarity with its(More)
Single feature polymorphisms (SFPs) are microarray-based molecular markers that are detected by hybridization of DNA or cRNA to oligonucleotide probes. With an objective to identify the potential polymorphic markers for drought tolerance in pigeonpea [Cajanus cajan (L.) Millspaugh], an important legume crop for the semi-arid tropics but deficient in genomic(More)
While scientific publishing is not typically taught to undergraduate students, we believe that an in-depth exposure to this topic might prove useful to those contemplating careers in neuroscience research or scientific writing and publishing. Here we describe a course designed to introduce students to most aspects of online publishing, from the details of(More)
Rice contains genetically and ecologically diverse wild and cultivated species that show a wide variation in plant and leaf architecture. A systematic characterization of leaf anatomy is essential in understanding the dynamics behind such diversity. Therefore, leaf anatomies of 24 Oryza species spanning 11 genetically diverse rice genomes were studied in(More)
Vincristine sulphate (VCS) is a vinca alkaloid obtained from the periwinkle plant (Catharanthus roseus) is the most widely recognized chemotherapeutic medications utilized for the treatment of a few types of malignancies. Moreover, VCS is a potent anticancer agent and drug of choice for the treatment of childhood and adult acute lymphocytic leukemia,(More)
This study set out to identify and characterize transcription factors regulating photosynthesis in rice. Screening populations of rice T-DNA activation lines led to the identification of a T-DNA mutant with an increase in intrinsic water use efficiency (iWUE) under well-watered conditions. Flanking sequence analysis showed that the T-DNA construct was(More)
