Areas of Research

Bud dormancy is an integral component of growth cycling, productivity and winter survival in perennial plant systems. It is an adaptive strategy for the survival of drought, high temperature, low temperature and freeze-dehydration stress. In a changing climate timing of dormancy induction and release are critical for sustainable production. Dormancy is not a static state, rather a dynamic phase of plant development that impacts the geographical range, yields and management strategies of many woody species, including grapevines (Vitis). My lab’s research programs are focused on the genetic, physiological and phenotypic aspects of grapevine bud dormancy, cold hardiness and chilling fulfillment. Specifically, to identify genes, pathways and genetic architecture which impact sustainable production of grapevine and other perennial systems. This knowledge is key to marker assisted selection of new materials, and identifying existing cultivars that are well-adapted to changing northern temperate environments and development of management strategies for sustainable production.

• Proteome development in grapevine bud during dormancy induction.
• Grapevine bud proteins and protein functional categories up-regulated in long (paradormant buds) and short (endodormant buds) photoperiods.

• QTL mapping for enological traits.
• Grapevine bud proteins and protein functional categories up-regulated in long (paradormant buds) and short (endodormant buds) photoperiods.

• Grapevine bud dormancy.
• Paradormancy maintenance and endodormancy induction in grapevine.

• Unraveling the genetic underpinnings of the adventitious root system architecture (RSA) is important for improving own-rooted and grafted grapevine sustainability for a changing climate. 
• Root morphology QTL hotspots and enriched gene networks are identified.

• Three grape berry enological traits mapped to candidate genes using an F2 mapping population.
