Areas of Interest
Plant Molecular and Cellular Biology
Our lab uses molecular genetic techniques to study plant cell biology and development. One organism studied is Arabidopsis thaliana, a member of the mustard family that has become an important model system for plant molecular biology. This area of research concentrates on the functional analysis of a family of genes encoding zinc finger proteins. The zinc finger motif is a DNA-binding domain found in transcription factors from a variety of plants and other non-green organisms. Little is known about the function of zinc finger proteins in higher plants.
Additional research is directed to applying the knowledge and tools developed for Arabidopsis, such as the germ-line transformation technique, to related plants. A primary focus in this regard is an analysis of the signal transduction pathway for flowering in biennials. The crucifer Barbarea verna is an obligate biennial; the cold, photoperiod, and hormone requirements for flowering in B. verna are being analyzed. A transformation protocol for B. verna is being developed, ultimately to study the effect of overexpression of Arabidopsis genes known to induce precocious flowering.
