Abstract
The invention relates to materials and methods for increasing the sucrose purity and total sugar content in stalks of sorghum plants at maturity. The methods involve an inbred or an F1 hybrid transgenic sorghum plant containing transgenes that affect developmental stages such as spikelet meristem identity, establishment of floral meristem identity, or floral organ initiation, development, or function.
Claims22
A sorghum plant, said plant comprising an exogenous nucleic acid comprising a regulatory region operably linked to a plant sterility sequence, wherein said plant sterility sequence affects a developmental stage selected from the group consisting of i) spikelet meristem identity, ii) establishment of floral meristem identity, and iii) floral organ initiation, development, or function;
- wherein the stalk of said sorghum plant has a sucrose purity that is higher at maturity than that of a corresponding control plant that lacks said exogenous nucleic acid.
A plurality of F1 transgenic sorghum seeds, said seeds comprising an exogenous nucleic acid comprising a promoter operably linked to a plant sterility sequence, wherein said plant sterility sequence affects a developmental stage selected from the group consisting of i) spikelet meristem identity, ii) establishment of floral meristem identity, and iii) floral organ initiation, development, or function;
- wherein F1 sorghum plants grown from said F1 seeds express said plant sterility sequence, and wherein stalks of said F1 sorghum plants have a sucrose purity that is higher at maturity than that from corresponding control plants that lack said exogenous nucleic acid.
