Mutant, non-naturally occurring, or transgenic plant cell: (i) encodes a neoxanthin synthase and encodes SEQ ID NO: 1 or SEQ ID NO: 1. A polynucleotide comprising, consisting of, or consisting essentially of a sequence having at least 60% sequence identity to SEQ ID NO: 6; (ii) a polypeptide encoded by the polynucleotide of (i); (iii) a polypeptide having at least 66% sequence identity with SEQ ID NO: 2 or having at least 60% sequence identity with SEQ ID No. 7; Or (iv) a construct, vector or expression vector comprising the isolated polynucleotide (i), wherein the expression or activity of the neoxanthin synthase is regulated relative to the control or wild-type plant. |
