Abstract
A tomato plant exhibiting a facultative parthenocarpy is provided. The plant comprises a loss-of-function mutation in a SlAGL6 gene and alternatively or additionally characterized by an average fruit weight/plant at least about the same as that of a non-parthenocarpic tomato of the same genetic background under fertilization permissive conditions of the non-parthenocarpic tomato. Also provided are methods of producing such plants and processed products produced from same.
Claims11
A tomato plant exhibiting a facultative parthenocarpy having a loss-of-function mutation in a homozygous form in a coding sequence of SlAGAMOUS-LIKE 6 (SlAGL6) gene,
- wherein said plant further exhibits (i) for fruits selected weighing minimum 8 grams each a fruit yield/plant at least about the same as that of a seed-bearing, non-parthenocarpic tomato of the same genetic background when grown together under identical conditions, wherein said about is defined as ±10%, and (ii) an average fruit weight/plant at least about the same as that of a seed-bearing, non-parthenocarpic tomato of the same genetic background when grown together under identical conditions, wherein said about is defined as ±10%, and wherein said loss of function mutation comprises (I) a mutation comprising a 175 nucleotide deletion, comprising the last 98 nucleotides of intron 1, all of exon 2 (76 nucleotides), and the first nucleotide of intron 2, or (II) a C268/t mutation in said SlAGL6 gene, said mutation resulting in a premature stop codon in said coding sequence.
