Accumulation of seed storage proteins and the taxonomy ofPoaceae

Comparison of Agronomic Characters, Total Seed Storage Proteins and their use for Genotypes Discrimination in the Kentucky Bluegrass (Poa PratensisL.)

“…These results are in agreement with electrophoretic protein studies that are previously performed (2,7,12,28,29). Also unpublished results of Van Dreven showed that in Kentucky bluegrass a correlation was found between similarities in esterase banding patterns of seed samples obtained by IEF and morphological characteristics.…”

“…While genotype 1 was placed in the first group, genotypes 9 and 11 that were only 4% different constituted the second group. Group III consisted of 4 genotypes (P. pratensis 3,5,7,8) which were 100% similar. At the same time this group was 90% similar to groups I and II.…”

Phylogenetic origin of Beckmannia (Poaceae) inferred from molecular evidence

“…In addition, their affinity is substantiated by their morphological, anatomical, and cytological similarities (Reeder, 1953). The close relationship between Beckmannia and Alopecurus is also supported by seed storage protein data (Chen et al, 1997). Hence, Beckmannia is closely related to Alopecurus.…”

N-terminal amino acid sequences of prolamins encoded by the alleles at the Pro1 and Pro2 loci in foxtail millet, Setaria italica (L.) P. Beauv.

“…This suggests that alleles at the Pro1 locus and those at the Pro2 locus have not arisen from an identical ancestral gene. The x-type and y-type prolamins encoded by alleles at the Pro2 locus showed homology with prolamin of Echinochloa crus-galli (83.3% with the x-type prolamin and 72.7% with the y-type prolamin, respectively) (Chen et al, 1997) and α -zein-like prolamins of maize (zein) (for 22kDa, 57.1% and 61.5%; for 19kDa, 50.0% and 46.2%), sorghum (kafirin) (57.1% and 53.8%) and Job's tears (coixin) (64.3% and 46.2%), assuming five to six residues as gaps (Ottoboni et al, 1993;Marks et al, 1985). Therefore, the x-type and y-type prolamins were designated as "α-zein-like prolamin".…”

“…b Reference: data of prolamin of Echinochloa crus-galli from Chen et al (1997), 22kDa α-zein, α-kafirin and α-coixin from Ottoboni et al (1993), 19kDa α-zein from Marks et al (1985) and pennisetin (prolamin of peral millet) from Bietz (1982). c Valine and leucine were detected at residue 8 with molar ratio of 1.75/1, and isoleucine and valine were found at position 23 with molar ratio of 2.75/1.…”
