Abstract
Molecular dissection of an adaptive epigenetic memory mechanism in norway spruce
Highlights
In Norway spruce, environmental conditions during the reproduction can greatly influence progeny performance
We found that the temperature during post meiotic megagametogenesis and seed maturation shift the growth cycle program of the embryos in the seeds, resulting in significant and long lasting phenotypic changes in the progeny
Traits that are affected include the timing of dehardening and bud burst in the spring; leader shoot growth cessation in the summer, and bud set and cold acclimation in the autumn
Summary
In Norway spruce, environmental conditions during the reproduction can greatly influence progeny performance.
