Dr. John D Goeschl, PhD.

John D. Goeschl, PhD. earned his PhD in Plant Physiology at the University of California at Davis conducting research with Dr. Harlan Pratt, he helped to prove that ethylene is a natural hormone causing fruit ripening.

For his doctoral dissertation he took his research further and proved that ethylene is also a growth hormone in plants.

During 18 years at Texas A&M University he was a member of an interdisciplinary team developing detailed mathematical models of plant processes such as photosynthesis, phloem transport, and sink metabolism in roots, stems, fruits and seeds.

In a joint project with the Duke University Phytotron, his team developed a unique method using the short-lived isotope Carbon-11 to study carbon flow dynamics in plants.

Based on discoveries made with that technology, he is currently studying the effects of environmental factors such as light, drought stress, and atmospheric CO2 on photosynthetic productivity and the control of flowering and fruit-set in plants.

Examples of his 33 publications are:
