Abstract
Aspects of the disclosure relate to plants, such as Solanaceae plants containing one or more branching events of a mutant Solyc04g005320 gene (or a homolog thereof), a mutant Solycl2g038510 gene (or a homolog thereof), and a mutant Solyc03gl 14840 gene (or a homolog thereof), as well as methods of producing such plants. In some aspects, such plants have one or more improved traits, such as modified inflorescence architecture, modified flower number, modified fruit number, higher yield, higher quality products, and higher fruit productivity.
Claims16
A genetically-altered tomato plant comprising:
- a mutant Solyc04g005320 gene comprising the sequence of SEQ ID NO:
- 4 or a mutant Solyc04g005320 gene comprising at least 99% sequence identity with the sequence of SEQ ID NO:
- 4,
- wherein the mutant Solyc04g005320 gene is a null allele, and
- wherein the genetically-altered tomato plant exhibits increased inflorescence complexity, increased flower production, and increased fruit production relative to a wild-type tomato plant.
A method for producing a genetically-altered tomato plant comprising:
- introducing a mutation into a Solyc04g005320 gene to produce a mutant Solyc04g005320 gene comprising the sequence of SEQ ID NO:
- 4 or a sequence comprising at least 99% sequence identity with the sequence of SEQ ID NO:
- 4 in a tomato plant, thereby producing the genetically-altered tomato plant containing the mutant Solyc04g005320 gene,
- wherein the mutant Solyc04g005320 gene is a null allele, and
- wherein the genetically-altered tomato plant exhibits increased inflorescence complexity, increased flower production, and increased fruit production relative to a wild-type tomato plant.
