*No End in Sight, Mysteries of the Telomeric Variation in Plants*


*Date:* Friday, October 3

*Time:* 12:00 pm-1:00pm

*Location: *Genomics Auditorium 1102


*Abstract:*
One of the most fascinating phenomena in evolutionary biology is the rapid
evolution of molecular complexes with conserved functions across the tree
of life. Because developmental processes are highly conserved across
eukaryotes, a naive evolutionary expectation is that the genes involved in
those processes would also be under high selective constraint and evolve
extremely slowly. The telomere, for example, is one such conserved
molecular complex. The telomere has crucial functions of protecting
chromosome ends and one might expect the components of the telomere would
be highly conserved and constrained from evolutionary change. However, in
this talk I will introduce the fascinating variation observed in plant
telomeres. I will present recent results from my group that highlights the
highly variable telomere length polymorphism and telomere sequence
variation from plant species Arabidopsis, rice, maize, and monkeyflowers.
>From our results I propose a biological link between the telomere and plant
