Abstract
Transposable elements (also known as ‘jumping genes’) are mobile genetic elements that can move from one locus in the genome to another. It was Barbara McClintock who discovered transposable elements when she was studying a particular variegation pattern of pigmentation in maize kernels. Initially the phenomenon of transposition was considered to be an anomalous feature unique to maize. In the years that followed we have learnt that transposons are found in all species, and in fact, transposable elements contribute to a large fraction of the genome in most eukaryotes.
In addition to moving from one locus to another in the genome, transposable elements can also cause a wide variety of genome rearrangements. In this seminar we will discuss the different kinds of rearrangements, the mechanism of rearrangements, the implications of such rearrangements, and the utility of such rearrangements in chromosome engineering.
Background biography of speaker:
Lakshminarasimhan Krishnaswamy obtained his BSc in Botany from The American College, Madurai, India. He joined the National Centre for Biological Sciences (NCBS), Bangalore, India, for his MSc and studied differential expression of genes in the brain of epileptic rats. However he realized he wasn’t comfortable doing research using animals and decided to move back to plants. He pursued his Ph.D. under the guidance of Dr. Thomas Peterson at Iowa State University, Ames, Iowa, USA, where he studied transposon mediated genome rearrangements in Arabidopsis. Then he moved to University of Missouri, Columbia, Missouri, USA, for a postdoctoral stint in Dr. James Birchler’s lab. Here he was involved in a project generating minichromosomes in maize. He has recently joined the School of Science, Monash University Sunway campus, where he enjoys teaching and is aspiring to establish a research lab to develop transposon based tools for genome engineering.
Convenor: Prof. Dr. Wickneswari Ratnam, PPSSSA, FST
