Stress tolerance and delayed senescence in plants

摘要

The novel constructs and methods of this invention improve tolerance in plants to environmental stresses and senescence. Nucleic acids encoding a plant farnesyl transferase are described, as are transgenic plants and seeds incorporating these nucleic acids and proteins. Also provided are non-naturally occurring mutations in the gene encoding farnesyl transferase which enhance drought tolerance in the plants, improve resistance to senescence and modify growth habit.

主权项

1. A plant having a non-natural loss-of-function mutation in the gene encoding farnesyl transferase beta, wherein said mutation is due to a T-DNA insertion or fast neutron mutagenesis and results in reduced farnesyl transferase beta activity in said plant.
