Abstract
The present disclosure provides compositions and methods related to improving trichome characteristics in tobacco plants. Plants comprising non-natural mutations in genes involved in trichome growth are provided, as are products and cured tobacco material made from said plants. Plants comprising RNAi constructs against genes involved in trichome growth are provided, as are products and cured tobacco material made from said plants. Methods of making and using the provided plants are also provided.
Claims23
A modified tobacco plant, or part thereof, comprising a non-natural mutation in an endogenous nucleic acid molecule, wherein the endogenous nucleic acid molecule encodes a HAIRPLUS1a (NtHAP1a) protein comprising the amino acid sequence of SEQ ID NO:
- 1, and wherein expression or activity of the NtHAP1a protein is reduced in the modified tobacco plant as compared to a control tobacco plant lacking the non-natural mutation when grown under comparable conditions.
A modified tobacco plant, or part thereof, comprising a non-natural mutation in an endogenous nucleic acid molecule, wherein the endogenous nucleic acid molecule encodes a HAIRPLUS1b (NtHAP1b) protein comprising the amino acid sequence of SEQ ID NO:
- 2, and wherein expression or activity of the NtHAP1b protein is reduced in the modified tobacco plant as compared to a control tobacco plant lacking the non-natural mutation when grown under comparable conditions.
A modified tobacco plant, or part thereof, comprising a non-natural mutation in an endogenous nucleic acid molecule, wherein the endogenous nucleic acid molecule encodes a HAIRPLUS2 (NtHAP2) protein comprising the amino acid sequence of SEQ ID NO:
- 3, and wherein expression or activity of the NtHAP2 protein is reduced in the modified tobacco plant as compared to a control tobacco plant lacking the non-natural mutation when grown under comparable conditions.
