1. Transgenic wheat grain comprising an exogenous polynucleotide which encodes a CslF6 polypeptide, and comprising between 3% and 8% (w/w) (1,3;1,4)-β-D-glucan (BG) which is characterised by one or both of:
a) a DP3/DP4 ratio between 1.0 and 2.3; and
b) partial water solubility such that between 8.0% and 25% of the BG of the grain is water soluble, as determined by a method that comprises treatment of a sample of wholemeal flour obtained from the grain with (i) 80% ethanol for 1 hour at 80° C., followed by (ii) solubilisation of BG in aqueous buffer for 2 hours at 37° C., and (iii) determination of the level of BG solubilised from the sample.
