“…Bioactive gibberellins are not only essential regulators for barley growth and development, but are also essential for malting and brewing [23]. It is expected that the deletion of the HvGA20ox2 gene in sdw1.a allele would result in reduced GA biosynthesis during the malting process.…”

BackgroundThe dwarfing gene sdw1 has been widely used throughout the world to develop commercial barley varieties. There are at least four different alleles at the sdw1 locus.ResultsMutations in the gibberellin 20-oxidase gene (HvGA20ox2) resulted in multiple alleles at the sdw1 locus. The sdw1.d allele from Diamant is due to a 7-bp deletion in exon 1, while the sdw1.c allele from Abed Denso has 1-bp deletion and a 4-bp insertion in the 5’ untranslated region. The sdw1.a allele from Jotun resulted from a total deletion of the HvGA20ox2 gene. The structural changes result in lower gene expression in sdw1.d and lack of expression in sdw1.a. There are three HvGA20ox genes in the barley genome. The partial or total loss of function of the HvGA20ox2 gene could be compensated by enhanced expression of its homolog HvGA20ox1and HvGA20ox3. A diagnostic molecular marker was developed to differentiate between the wild-type, sdw1.d and sdw1.a alleles and another molecular marker for differentiation of sdw1.c and sdw1.a. The markers were further tested in 197 barley varieties, out of which 28 had the sdw1.d allele and two varieties the sdw1.a allele. To date, the sdw1.d and sdw1.a alleles have only been detected in the modern barley varieties and lines.ConclusionsThe results provided further proof that the gibberellin 20-oxidase gene (HvGA20ox2) is the functional gene of the barley sdw1 mutants. Different deletions resulted in different functional alleles for different breeding purposes. Truncated protein could maintain partial function. Partial or total loss of function of the HvGA20ox2 gene could be compensated by enhanced expression of its homolog HvGA20ox1 and HvGA20ox3.

“…Between them, noteworthy are: barley [10], buckwheat [3] (although it is not a cereal grain, it is usually grouped with other cereals because of a similarity in cultivation and utilization) and peas [7]. Grains of barley and buckwheat are used to produce frequently consumed groats and flakes [3, 10, 11] and pea seeds are consumed by humans principally as green immature seeds [7, 11]. Phenolic acids are the most important and the largest group of antioxidants in terms of incidence in cereal grains [6, 10, 11] and peas [7].…”

“…They consist of two subgroups, i.e., hydroxybenzoic and hydroxycinnamic acids [5, 9]. The forms of salicylic, p-hydroxybenzoic, vanillic, protocatechuic, p-coumaric, syringic, ferulic and sinapic acids have been identified in barley grains [10, 11]. The bran-aleurone fraction of buckwheat contains bound syringic, p-hydroxybenzoic, vanillic and p-coumaric acids [6].…”

The aim of the study was to determine whether phenolic compounds in some varieties of buckwheat, winter and spring barley and peas can be used as factors which distinguish selected cultivars and varieties of plant material. It was observed that the content of total phenolics might be useful as a cultivar-distinguishing factor for all the plant materials analyzed, but it was a distinguishing factor for only some varieties. Individual cultivars and varieties were best distinguished by the content of syringic acid. The levels of syringic and vanillic acids were in reverse proportion to the total amount of phenolics soluble in methanol and a positive correlation between syringic and ferulic acid was observed. Moreover, the protein content of plant material was analyzed and a significant (p ≤ 0.05) correlation between this component and ferulic and vanillic acids was noted.

Barley semidwarf allele sdw1.d improves malting quality indirectly in a near isogenic line

Background and ObjectivesMalt barley is a specialty crop in which quality characteristics are as important as grain yields. Short stature genes used to increase grain yields in barley have variable effects on malt quality. Effects of sdw1.d semidwarf gene on malting quality were examined using a near isogenic line (NIL) in six field trials.Findingssdw1.d increased malt extract percentage significantly in five trials by 1.7% and decreased test weight (2.0–3.5 kg) in three trials. Grain weight increased in three trials where lodging was common while decreasing in two where lodging was not severe and not changing in one. Diastatic power of sdw1.d NIL was significantly higher in four trials and similar in two trials compared to recurrent parent Tokak. No change was observed for α‐amylase activity.ConclusionsThe lack of reports indicating a direct association of Sdw1 mutants with diastatic power and the presence of quantitative trait locus (QTL) around the Sdw1 gene in numerous studies implied that higher diastatic power of the NIL could be due to linkage rather than the pleiotropic effect of sdw1.d.Significance and NoveltyImproved malting quality of the NIL appeared to be the result of indirect effects of sdw1.d due to reduced lodging and linkage with diastatic power QTL.
