Roles of mitochondrial energy dissipation systems in plant development and acclimation to stress.

abstract：BACKGROUND AND AIMS:Lomatium dissectum (Apiaceae) is a perennial, herbaceous plant of wide distribution in Western North America. At the time of dispersal, L. dissectum seeds are dormant and have under-developed embryos. The aims of this work were to determine the requirements for dormancy break and germination, to cha...
