Development and validation of the OVATE gene-based functional marker to assist fruit shape selection in tomato.

ABSTRACT: Fruit size, shape and colour are important determinants of fruit quality in tomato. Among the different genetic factors, the OVATE gene is a key regulator of fruit elongation in tomato. The loss-of-function recessive ovate allele results from a functional single nucleotide polymorphism (SNP) in the second exon of the gene to produce fruit elongation and variable fruit shapes in different genetic backgrounds. The mutation has also been associated with increased fruit firmness, a desirable trait for processing purpose of tomato. However, the recessive nature of this important mutant allele makes its identification and utilization in breeding programme difficult. Hence, we developed the OVATE gene-based functional marker using the tetra-primer amplification refractory mut
