Abstract
The present invention relates to a plant obtained by mutagenesis, such that the expression and/or the activity of the ESK1 protein and the expression and/or the activity of the TPS7 protein are diminished compared to a non-mutagenated plant. Said plant with biomass that has better digestibility maintains satisfactory growth. A further aim of the present invention is a method for preparing said plant, as well as the use of said plant for the production of biofuel.
Claims9
A plant obtained by a mutagenesis method comprising
- decreasing the expression and/or the activity
- of the protein designated ESK1 and
- of the protein designated TPS7,
- in said plant, as compared to a non-mutagenized parent plant, and the decrease in the expression and/or the activity of the ESK1 and TPS7 proteins is achieved by introducing at least one mutation in each of the genes encoding the ESK1 and TPS7 proteins in said plant, and such that:
- the non-mutagenized ESK1 protein has at least 50% identity with the sequence SEQ ID NO:
- 1 and comprising the acyl esterase and transmembrane domains, and
- the non-mutagenized TPS7 protein has at least 60% identity with the sequence SEQ ID NO:
- 2 and comprising the TPS and TPP domains.
A method for increasing the growth of a plant carrying the esk1 mutation, comprising a step of genetically modifying said plant to decrease the expression and/or the activity of the protein designated TPS7.
