- Ph.D. Biochemistry, Texas A&M University, 1999
Research Interests
Dr. Larkin's research focuses on the molecular and chemical ecology of
native plant species, in particular their interaction with their environment
and response to habitat fragmentation. It includes both specific events,
such as the effect of temperature on the expression of allelic variants of a
single enzyme (Granule Bound Starch Synthase) and broader events, such as
the genetic relationships among populations in fragmented habitats. Some of
the plant species studied include rice (Oryza sativa L.), shoalgrass
(Halodule beaudettei), turtlegrass (Thalassia testudinum) bundleflower
(Desmanthus virgatus) and Kleberg's bluestem (Dichanthium annulatum). His
research involves characterization of genomic and organellar DNA variation
and expression through DNA sequencing, Amplified restriction Fragment Length
Polymorphism (AFLP), Random Amplification of Polymorphic DNA (RAPD), and
Microsatellite (STR) analysis. Field, molecular and environmental data are
used to examine how plants respond and, eventually, adapt to their
environments.
