Low temperatures impact dormancy status, flowering competence, and transcript profiles in crown buds of leafy spurge.

ABSTRACT: Leafy spurge (Euphorbia esula) is an herbaceous perennial weed that produces vegetatively from an abundance of underground adventitious buds. The objectives of this study were to determine how mimicking natural seasonal conditions (photoperiod and temperature) under controlled environmental conditions affect dormancy and flowering competence; to determine molecular mechanisms associated with well-defined phases of seasonal dormancy transitions based on transcript profiles obtained by microarray analysis; and to link mechanisms regulating induction and release of endodormancy and flowering competence. Reduction in temperature (27 to 10°C) and photoperiod (16 to 8 h) over a three-month period induced a para- to endo-dormant transition in crown buds. An additional eleven weeks of prolonged c
