Abstract
The present invention relates to a polynucleotide encoding a mutated patatin phospholipase protein, which mutated protein leads to an improved haploid induction rate. The invention further relates to the mutant patatin phospholipase protein and to methods and compositions for improved plant breeding using haploid induction. Sorghum plants which are capable of haploid induction with improved induction performance are described.
Claims18
A mutated polynucleotide encoding a mutated patatin phospholipase protein wherein the said protein comprises aspartic acid (D) at position 41 instead of glycine (G).
A mutated patatin phospholipase protein, comprising an amino acid substitution from glycine (G) to aspartic acid (D) at position 41.
A sorghum haploid inducer line comprising one or more mutations in the endogenous gene encoding a patatin phospholipase,
- wherein the one or more mutations lead to at least the amino acid substitution from glycine (G) to aspartic acid (D) at position 41 of the papatin phospholipase protein.
