RESEARCH EXPERIENCE The Role of TLH genes in telomere maintenance
[Jan 2007 to Dec 2008]
The ends of linear chromosomes have evolved into specialized, multi-functional chromatin domains. These domains include the telomere proper, which typically consists of simple repetitive DNA sequences and the proteins that bind to them, and the subtelomeric region, a less well-defined domain which often includes more complex repetitive DNA elements. Telomeric repeats and their binding proteins are well conserved and their function is, in principle, understood. In contrast, subtelomeric elements vary among species and even among varieties of a single species, and their functions are unknown. We are using Aspergillus nidulans to study the function of telomere-linked helicase (TLH) genes, which are conserved, fungal-specific subtelomeric sequences. As part of our investigation to study tlhA function,multiple tlhA::Af pyrG mutants were created, each of which exhibited the same two phenotypes: slow colony growth and defective ascosporogenesis. Based on our observations we speculate that telomeric heterochromatin represses TLH and other subtelomeric genes during vegetative growth and further speculate that changes in telomere structure during ascosporogenesis underlie the enhanced TPE phenotype we observe during sexual reproduction. This work was done under the guidance of Dr. Peter M. Mirabito, Department of Biological Sciences, University of Kentucky.
Interaction of CG14011 product with HOAP protein
[Aug 2006 to Dec 2006]
Drosophila Heterochromatin protein (HP1) complex contains subunits of the Origin Recognition Complex, known to bind and recruit DNA replication factors to specific sequences in the initiation of DNA replication. The association of this heterochromatin protein with DNA replication proteins suggests a mechanism for linking the process of heterochromatin assembly to that of DNA replication. This complex contains a second previously uncharacterized DNA-binding activity that we have designated as HP1/ORC-Associated Protein (HOAP). We have found this protein to function in the assembly of a specific heterochromatic structure at chromosome ends that prevents them from undergoing end-toend fusions. A Two Hybrid Screen of cDNA library with HOAP gave a list of possible candidates of which CG14011 is a testes specific gene. To confirm the interaction of the HOAP protein with CG14011 gene product, an co precipitation assay was done using radioactively in vitro translated CG14011 gene and HOAP protein. The result of interaction between the two proteins have been conclusively demonstrated. This work was done under the guidance of Dr. Rebecca Kellum, Department of Biological Sciences, University of Kentucky. Reconstitution of Dihaploids from Leaf Tissue of Anther Derived Haploids and Molecular Characterization [January 2006-June 2006] Haploid plants have many uses in genetics and plant breeding research. There are numerous ways of producing individuals which include twin selection, wide crossing, and in vitro techniques such as anther culture, pollen culture and ovule culture, which rely on our ability to divert tissues with gametic (haploid, n) chromosome number to develop as sporophytes while retaining the haploid chromosome complement. However, haploid plants are shorter than diploids, weaker, and sterile because of univalent chromosomes. However, it happens with some haploid plants that the meiotic division takes place in macrosporogenesis and microsporogenesis and these results in spontaneous development of a fertile diploid plant. It was indicated that ‘aged’ plant portions might be useful in developing diploids by way of tissue culture techniques. Thus the problem was to locate cells, in selected haploid plants, that were capable of dividing and organizing into normal diploid plants. Several plant components were tested to determine their usefulness in production of diploids from haploids that had grown to the flowering stage as part of their selection procedure. It was found that leaf mid veins from aged leaves (those that remained on the plants 3 to 4 weeks after attaining full expansion) when cultured in chemically defined media gave rise to diploids which were normal in appearance; self fertile and produced diploid progeny. In a period of 3 months, anther derived haploids were raised and were subjected to leaf mid vein culture by optimizing media favoring development of dihaploids. A large number of haploids have been cultured to produce dihaploids. This work was done under the guidance of Dr.Sarala, Biotechnology Division, Central Tobacco Research Institute, Rajahmundry.
