Inheritance of the storage protein (gliadin and glutenin) genes of Triticum macha Dek. et Men. and their allelism to Triticum aestivum L. genes have been studied. A close homology of at least chromosomes 1A and 1B of the two species has been found. Results confirm a very close relationship between T. macha and T. aestivum.Key words: seed storage proteins, genetic analysis, chromosome homology, relationship of Triticum macha Dek. et Men. and Triticum aestivum L.

The objective of our study was to determine the composition of high-molecular weight-glutenin subunits (HMW-GS) in 120 cultivars of common wheat (Triticum aestivum L.). Fourteen alleles and 34 allelic compositions were detected using sodium dodecyl sulphate-polyacrylamide gel electrophoresis. The most frequent HMW-GS alleles at the Glu-A1, Glu-B1 and Glu-D1 loci were null (57.1%), 7+9 (43.3%) and 5+10 (61.9%), respectively. However, low-frequency HMW-GS alleles were also observed, such as 13+16, 20, 21, 7 and 18, encoded by the Glu-B1 locus, and 4+12, encoded by the Glu-D1 locus. The wheat–rye 1BL.1RS translocation was identified in 25 cultivars, using acid polyacrylamide gel electrophoresis. The Glu-score varied greatly, and some lines reached the maximum value of 10.

ABSTRACT: Seed germination is a complex process controlled by many factors, in which physical and biochemical mechanisms are involved and the mobilization of reserves is crucial for this process to occur. Although, seed reserve mobilization is usually thought to be a post-germination process, seed reserve proteins mobilization occurs during germination. This study quantified seed proteins of bean genotypes during different hydration times, in order to understand the process of protein mobilization and whether there is relationship of this biochemical component with seed vigor. This study was conducted using seeds with different levels of vigor, genotypes with highest (13, 42, 55 and 81) and lowest (07, 23, 44, 50, IPR-88-Uirapurú and Iapar 81) physiological quality. High vigor genotypes showed greater efficiency in hydrolysis and mobilization of protein component, because they presented low globulins content in cotyledons at radicle protrusion in relation to low vigor genotypes (07, 23 and 50). The protein alpha-amylase inhibitor, observed in all genotypes, is involved with the longer time needed for radicle protrusion, according to the band intensity difference in genotypes 07, 44 and Iapar 81.

Agronomical Traits

Chinese landraces of wheat (Triticum aestivum L. em Thell.) have had significant contributions not only to wheat production, but also to wheat improvement. Mazhamai is one of the most distinctive landraces, and has been used as a foundation parent in developing many outstanding improved cultivars in China. The objective of this study was to determine the genetic relationships of eight wheat landraces with the name Mazhamai, collected from wheat-producing regions with various geographical and microgeographic environments using morphological and agronomical traits, the composition of their gliadins and high-molecular-weight glutenin subunits (HMW-GS) and microsatellite markers. These homonymous accessions of Mazhamai differed, to some extent in their morphological and agronomical traits, gliadin composition, and microsatellite markers, but not for the HMW-GS and similar profiles for 52 of the SSR markers. This suggests that genetic variation must have occurred during the long-term growing of the Mazhamai accessions in various geographical regions. Furthermore, microsatellite analysis also revealed that the B genomewas more variable than the A and D genomes and chromosomes 2A and 2B were the most variable chromosomes among the Mazhamai accessions. However, chromosomes 1A, 1D, 2D, 5B, and 7A were conserved for the SSR loci used in the study. Key words: Wheat landraces, Mazhamai, genetic relationship, gliadin, glutenin, microsatellites

Genetic diversities of 106 Avena accessions, including diploid, tetraploid and hexaploid species, derived from different countries were characterized based on seed storage proteins polymorphism using SDS-PAGE. A total of 24 protein bands and 72 protein patterns were detected in all 106 accessions. The genetic similarity value varied from 0.50 to 1.00. The seed storage protein patterns were largely independent of environmental fluctuation. Accessions of the same species or with identical genome constitutions had the same or similar protein patterns. Relatively lower within-species variations were observed compared with among-species variations. The AACCDD genome hexaploid species and the AA genome diploid species were more divergent than other species, with percentages of polymorphic bands of 85.7% and 61.1% respectively. In the AA genome diploid species, the AsAs genome diploids displayed higher variations than the modified AA genome diploid species. Clustering results showed a close relationship between the hexaploid species and the AACC genome tetraploid species. The AABB genome tetraploid species were similar to the AsAs genome diploid species, with the exception of the species A. agadiriana with AABB genome constitution, which showed a close relationship with the AcAc genome diploid species A. canariensis and the polyploid species carrying the A and C genomes.
