Abstract
The present disclosure provides the identification of promoters that are preferentially active in tobacco axillary buds. Also provided are tobacco plants comprising reduced or no sucker growth. Also provided are methods and compositions for producing tobacco plants comprising reduced or no sucker growth.
Claims17
A nucleic acid molecule comprising a promoter active in axillary bud tissue, but not active in a tobacco seed, wherein said promoter:
- (a) comprises SEQ ID NO:
- 257;
- and
- (c) is operably linked to a heterologous nucleic acid molecule.
A tobacco plant comprising a nucleic acid molecule comprising a promoter, wherein said promoter:
- (a) comprises SEQ ID NO:
- 257;
- and
- (b) is operably linked to a heterologous nucleic acid molecule,
- wherein said tobacco plant comprises no suckers or reduced suckers after topping as compared to a control tobacco plant of the same variety when grown under comparable conditions, wherein said control tobacco plant lacks said promoter operably linked to said heterologous nucleic acid molecule.
