“…This later family provides additional opportunities for increasing polymorphism resulting from its neutral nature at evolution level and its high tolerance to mutations. One cause of this variability may be the linkage of the hordein loci to the Mla locus, which specifies the resistance to different races of powdery mildew (Oram et al 1975).…”

“…From the crosses between the 6 high lysine lines, the presence of five different genes leading to shrivelled seeds are indicated, the genes in mutants 29 and 86 being allelic. In addition, the results show that the five genes are unlinked, with the possible exception of the two in Hiproly and two in mutant 56, where the equal number of smooth and shrivelled F,-seeds indicate a recombination value of approximately 25 %.The close relationship, observed in the present investigation, between grain filling and DBCP,,.,, the results of DOLL (1975), ORAM et al (1975 and the discovery of a high lysine mutant associated with the shrunken endosperm condition caused by the gene seg I (ESLICK and HOCKETT 1975) seem to justify the assumption that the two characters are at least in part governed by the same genes. A similar relationship is also present in the high lysine mutant Opaque-2 in maize (BALINT et a].…”

Thirteen characters describing the seed proteins and yield capacity of four normal and six high lysine barley lines were investigated in a diallel cross. For all the lines there was a highly significant negative correlation between content of crude protein and its dye‐binding capacity per unit of protein. The average regression coefficient was ‐0.027 in the normal lysine lines. In the high lysine mutant 1508 it was ‐0.060 and ‐0.038 in the remaining high lysine lines. For all characters except two, significant differences were revealed between the averages of the normal and the high lysine lines. When four of the high lysine mutant lines were compared with their respective mother lines, significant differences were detected for most of the characters. On the basis of classification of the F2‐seeds from the complete diallel cross for grain filling, it was shown that the six high lysine lines contain five different recessive genes leading to shrivelled seeds. These genes seem to be independent, except in Hiproly and the mutant 56, where linkage between two of them was indicated. Due to the close negative relationship between the degree of grain filling and the dye‐binding capacity of the seed proteins, a pleiotropic action for the two characters is inferred.

“…Shrunken seed endosperm is associated with the pleiotropic effects of the lys3.a gene 20 , which is located on chromosome 7 21 . Apart from showing a drastic change in protein composition, the lys3.a mutant also contains higher amounts of free amino acids and sugars 22 . The lys3.a gene is most likely found in the cluster of hordein genes 23 , 24 .…”

The development of crop varieties tolerant to growth temperature fluctuations and improved nutritional value is crucial due to climate change and global population growth. This study investigated the metabolite patterns of developing barley seed as a function of genotype and growth temperature for ideal vegetable protein production and for augmented β-glucan production. Seeds from three barley lines (Bomi, lys3.a and lys5.f) were sampled eight times during grain filling and analysed for metabolites using gas chromatography-mass spectrometry (GC-MS). The lys3.a mutation disrupts a regulator gene, causing an increase in proteins rich in the essential amino acid lysine, while lys5.f carries a mutation in an ADP-glucose transporter gene leading to a significant increase in production of mixed-linkage β-glucan at the expense of α-glucan. Unique metabolic patterns associated with the tricarboxylic acid cycle, shikimate-phenylpropanoid pathway, mevalonate, lipid and carbohydrate metabolism were observed for the barley mutants, whereas growth temperature primarily affected shikimate-phenylpropanoid and lipid metabolism. The study applied recently developed GC-MS metabolomics methods and demonstrated their successful application to link genetic and environmental factors with the seed phenotype of unique and agro-economically important barley models for optimal vegetable protein and dietary fibre production.
