Loss of vesicle

Screening for no-heat mutants in Capsicum collections and populations is a common practice for pepper breeders, as capsaicinoid accumulation is unique to the members of genus. A second locus for control of capsaicinoid production exists in at least two other species, C. chinense and C. chacoense [82], and the mutation that revealed this second locus is called loss of vesicle (Lov). The blisters on the placental surface that fill with capsaicinoids are absent in these no-heat mutants. The gene product and map location of this mutation are not known.
