Our lab is focused on both applied and basic aspects of plant water and nutrient physiology and management.

 

Plant water use and stress physiology

Our group uses a number of model species to identify the genetic basis for improved water use efficiency (WUE) in plants (Yoo et al., 2009). Recent work (Yoo et al., 2010) provides exciting evidence for the role of stomatal development on WUE and water stress tolerance in plants. Ongoing projects in the lab are focused on the identification and characterization of flowering time transcription factors that may also regulate WUE, identification of WUE genes in the model species Thellungiella halophila, the identification of QTL associated with WUE in maize, and the effect of transpiration rate on nutrient uptake in plants.

 

Plant nutrition

Our work on plant nutrition is undertaken to provide science-based recommendations to growers in Indiana and throughout the U.S. Published research has resulted in refined protocols for tissue (HortSci, 2010) and container (HortTech, 2009) nutrient sampling, and ongoing research has provided the basis for reducing container production fertilizer rates. Currently, we are also utilizing stable isotopes to track nitrogen fates in container plants.
