Breaking endodormancy in leafy spurge crown buds by dehydration-stress and vernalization identifies overlapping molecular networks linked to growth regulators

ABSTRACT: Persistence of the invasive perennial weed leafy spurge is mainly attributed to seasonal production of underground adventitious buds (UABs), which undergo well-defined phases of dormancy (para-, endo- and eco-dormancy). These well-defined phases of dormancy also allow UABs of leafy spurge to survive extreme seasonal variations, including dehydration-stress. Consequently, objectives of this study include understanding the effects of dehydration-stress on vegetative reproduction, flowering competence, and transcript profiles at different phases of bud dormancy. The vegetative growth potential of UABs was monitored by removing the aerial portion of dehydration-stressed plants and re-watering the root system. Further, microarray analysis was used to follow transcriptome profiles to identify cr
