Fuente: WIPO "tomato" A member of the Solanum species, such as a tomato (Solanum lycopersicum) plant, is provided that exhibits a jointless phenotype, wherein the plant comprises a Jointless-2 (j2) allele that is defined by the removal or disruption of a splice site within the SlMBP21 (Solyc12g038510) gene The removal or disruption of a splice site results in the complete or partial loss of at least one exon in an mRNA transcribed from a SlMBP21 gene (Solyc12g038510). More particularly, the removal or disruption of a splice site results in the complete or partial loss of exon 5 in an mRNA transcribed from a SlMBP21 gene (Solyc12g038510). The removal or disruption of a splice site may be carried out using precision breeding techniques.
