“…Allelic variation of wheat storage proteins, which directly form a part of wheat gluten, provide a basis for studying relationships between the particular gluten proteins and wheat's bread-making properties. Although protein markers have been supplanted by DNA markers in many cases and various molecular methods are regularly used as breeding tools in marker-assisted selection (MAS) systems, protein alleles remain highly effective for wheat breeding purposes as genetic markers for the prediction of technological (baking) parameters (Zheleva et al 2007).…”

Using vertical electrophoresis, a set of 22 biotypes heterogeneous according to their gliadin alleles as well as their low-molecular-weight (LMW) and high-molecular-weight (HMW) glutenin subunits were identified in 10 winter wheat varieties registered in the Czech Republic. The effects of individual biotypes and their specific allelic compositions on 16 grain quality parameters were investigated. Inter-varietal differences in particular quality parameters (Zeleny sedimentation, farinograph water absorption, several values of the solvent retention capacity test) were significantly greater than the differences detected among biotypes of each variety. Special attention was given to the LMW glutenin subunits and gliadin alleles and to mutual interactions responsible for significant differences in the tested grain parameters. The results revealed at least one case of significant differences in grain quality parameters among biotypes of eight heterogeneous wheat varieties. This work unambiguously indicates that the high prevalence of wheat biotype(s) with significantly poorer values in some grain parameters can also decrease the expected technological quality of the original wheat variety. In particular, multi-line wheat varieties carrying alleles Glu-B1 (6+8) and Glu-B1 (7+9) or Glu-B3j and Glu-B3g can indicate the possibility of some significant changes in grain quality parameters.

Alfalfa (Medicago sativa L.) is a perennial and outcrossing species, widely grown as a forage legume for hay, pasture and silage. The genetic engineering approaches involve the transfer of useful or novel gene(s) into alfalfa to improve desired traits. The recent development of genetic engineering is extensively applied to basic and applied research for alfalfa improvement, including improvement of herbicide resistance, reinforcement of the resistance to biotic and abiotic stresses, production of novel compounds, improved yield for industrial and/ or pharmaceutical proteins and renewable energy sources. On the other hand, alfalfa forage needs to possess additional fermentable carbohydrates, proteins with a balanced amino acid profile that are gradually degraded in the rumen of domestic livestock, and zero anti-nutritional factors, which are the major concerns of recent interest in alfalfa. However, an advance of transgenic approach is contentious, requiring vigilant experimental methods and design to contest bio-safety challenges. More importantly, the technology of clustered regularly interspaced short palindromic repeats (CRISPR) is rapidly growing and might be a game player or changer in alfalfa. The present review can enable us to identify the proper direction, get familiar with new research methods and success of genetic engineering technology in alfalfa, to produce maximally improved cultivars.

Durum wheat genotypes including 7 landraces and 17 breeding varieties were studied. Polyacrylamide gel electrophoresis under acidic conditions of pH 3.1 was used to study gliadin and glutenin polymorphisms. In total, 32 gliadin and 8 high molecular weight glutenin alleles were identified. The contribution of B genome (58.5%) to the allelic variation of durum wheat varieties was higher than of A genome. The cluster analysis delineated genotypes into four main clusters. According to cluster analysis, legitimacy identifying the distribution of botanical varieties through the tree was observed. The study confirms the suitability of biochemical markers for cultivar identification and genetic relation study in durum wheat genotypes.
