Abstract
This disclosure provides tobacco plants that exhibit altered photosynthesis as well as methods of making and using such plants.
Claims20
A method of making a Nicotiana tabacum plant, comprising:
- selecting a N. tabacum plant comprising a non-natural mutation in an endogenous nucleic acid sequence selected from the group consisting of SEQ ID NOs:15 and 17;
- crossing or selfing said selected N. tabacum plant to produce at least one progeny seed;
- and
- obtaining at least one progeny N. tabacum plant grown from said progeny seed,
- wherein said obtained progeny N. tabacum plant comprises said non-natural mutation.
2 more elements
A Nicotiana tabacum plant, or part thereof, comprising an altered photosynthesis phenotype and reduced activity of a polypeptide selected from the group consisting of SEQ ID NOs:16 and 18;
- wherein said altered photosynthesis phenotype is selected from the group consisting of a reduced concentration of thylakoid membranes in the photosystems, a reduced amount of total chlorophyll, an increased ratio of chlorophyll a to chlorophyll b, and an increased biomass;
- wherein said reduced or increased amounts are in comparison to a N. tabacum plant having wild-type activity of a polypeptide selected from the group consisting of SEQ ID NOs:16 and 18.
A Nicotiana tabacum plant, or part thereof, comprising a mutation in an endogenous nucleic acid, the wild type endogenous nucleic acid encoding a sequence selected from the group consisting of SEQ ID NOs:16 and 18.
