Hordoindolines, the tryptophan-rich polypeptides affecting grain hardness in barley, appeared as three pairs of polypeptides in the acidic polyacrylamide gel electrophoresis (A-PAGE) and two-dimensional A-PAGE × SDS-PAGE patterns of starch-granule proteins from 18 barley cultivars. On capillary RP-HPLC/nESI-MS/MS spectrometry, one pair of polypeptides was(More)
Nectarines play a key role in peach industry; the fuzzless skin has implications for consumer acceptance. The peach/nectarine (G/g) trait was described as monogenic and previously mapped on chromosome 5. Here, the position of the G locus was delimited within a 1.1 cM interval (635 kb) based on linkage analysis of an F2 progeny from the cross 'Contender' (C,(More)
Four perennial wheat genotypes derived from crosses between Triticum aestivum and Thinopyrum elongatum, Th. intermedium or Th. ponticum were grown in Central Italy over 2 years of testing, and compared for their agronomical, biochemical, nutritional and technological traits with three commercial common wheat cultivars. Perennial wheat derivatives were(More)
Among cereals, Avena sativa is characterized by an extremely soft endosperm texture, which leads to some negative agronomic and technological traits. On the basis of the well-known softening effect of puroindolines in wheat kernel texture, in this study, indolines and their encoding genes are investigated in Avena species at different ploidy levels. Three(More)
Vromindolines, a family of oat starch-bound proteins responsible for the extremely soft endosperm of this cereal, are characterized by a tryptophan-rich domain and ten conserved cysteine residues, as it was observed in the starch-bound proteins from other cereals, and proved to be specific of the genus Avena. Two-dimensional electrophoresis of vromindolines(More)
BACKGROUND The availability of the peach genome sequence has fostered relevant research in peach and related Prunus species enabling the identification of genes underlying important horticultural traits as well as the development of advanced tools for genetic and genomic analyses. The first release of the peach genome (Peach v1.0) represented a high-quality(More)
Oat kernels exhibit an extra-soft texture, a trait recently demonstrated to be largely modulated by starch-bound tryptophan-rich 2S proteins, the vromindolines. In this study, fractionation by two-dimensional electrophoresis of starch-bound proteins in 25 oat (Avena sativa) cultivars and 11 diploid or tetraploid Avena species revealed novel 2S proteins(More)
