“…Most of the estimations on the carotenoid content made on tritordeum did not provide detailed information about the individual composition of the pigment profile due to the lack of specificity of the traditional analytical methods employed for the characterisation of carotenoids in cereals. By means of estimations such as YPC, levels of carotenoids in the order of 5 to 6 times higher (in the range of 11-13 µg/g) have been found in tritordeum with respect to common wheat (2 µg/g) and 2 to 3 times higher with respect to durum wheat (5-6 µg/g) (Álvarez et al 1995;Martín et al 1999), which is comparable to the levels reported for Einkorn wheat. In an extensive study which evaluated a total of 35 primary lines of tritordeum together with their respective parental lineage, 27 H. chilense accessions and 19 durum wheat cultivars, the average levels of carotenes (µg/g of β-carotene equivalents, determined as YPC) for the amphiploid continued to be in the order of 2 times higher than durum wheat parent, but 3 times lower than the average of H. chilense (Álvarez et al 1999).…”

Cereals are considered to be a major source of carbohydrates and proteins as well as minor micronutrients such as mineral, vitamins and antioxidants, including carotenoids. Carotenoids are natural lipophilic pigments biosynthesized mainly by plants, and certain bacteria and fungi. Cereals, although having a low carotenoid content when compared with the majority of fruits and vegetables, may have an important impact in the nutritional status of consumers. The daily consumption of cereals, and products derived from them, by a large part of the population, especially in underdeveloped and developing countries, makes cereals a contributor of carotenoids which should not be overlooked and must be taken into consideration in biofortification strategies. In the present manuscript, we revise the existing information about the composition and distribution of carotenoids in cereals, highlighting factors which alter their profile, such as domestication of wild varieties, genotype, storage, milling and processing techniques. Strategies for stimulating the carotenoid content in cereals, either by means of traditional breeding methods or by genetic manipulation, are also discussed.

“…In fact, from the crosses between H. chilense and diploid, tetraploid and hexaploid wheats originated fertile amphiploids, noted as Tritordeums (ÂTritordeum Ascherson et Graebner). Hexaploid tritordeum (2n ¼ 6x ¼ 42, AABBH ch H ch ) shows promising characteristics as a new crop (Martín et al 1999) having some potential for breadmaking (Alvarez et al 1995;Alvarez and Martín 1996). The influence of endosperm storage proteins on breadmaking quality makes necessary the study of this component in both tritordeum and H. chilense: in fact some authors (Alvarez et al 1993(Alvarez et al , 1999a studied the endosperm storage proteins from hexaploid tritordeum using SDS-PAGE and acid-PAGE methods.…”

Hordeum chilenseRoem. et Schult. shows interesting characteristics for breeding, such as disease or pest resistance and has high variability for endosperm storage proteins, valuable for the improvement of the breadmaking quality of both tritordeum and wheat. Knowledge of the genetic structure and the level of H. chilense genetic diversity within its distribution zone may be important to decide on breeding strategies as well as management procedures. The pattern of genetic variation within and among different regions of the distribution area of H. chilense, was analysed by endosperm storage proteins (gliadin and low-molecularweight glutenin subunits). Several analyses were performed including AMOVA, direct correlation between phenotypic and geographic distance matrices and spatial genetics differentiation. Most genetic diversity was caused by differences among individuals within a population, although all the analyses performed suggest the existence of a low degree of differentiation within regions. Correlation values between phenotypic and geographic distances were low but significant. The spatial genetics analysis revealed that the average phenotypic distances of each of the spatial distance class were not lower (or higher) than that expected by chance. These results are explained by their neutral behaviour towards a selection of endosperm storage proteins and could be very useful in optimising future sample collecting strategies.

“…Primary tritordeums exhibit enormous genetic variability for many valuable agronomic and quality traits. For example, the grain and flour from tritordeum has similar functional properties to bread wheat [ 1 ], but with higher pigment content [ 2 , 3 ]. Most of this genetic variability can be attributed to H. chilense , a wild relative of cultivated barley ( H. vulgare L.) that occurs exclusively in Chile and Argentina which is highly polymorphic both morphologically and biochemically.…”

Comparative genomic analysis and expression of the APETALA2-like genes from barley, wheat, and barley-wheat amphiploids

et al. 2009

View full text Add to dashboard Cite

Background: The APETALA2-like genes form a large multi-gene family of transcription factors which play an important role during the plant life cycle, being key regulators of many developmental processes. Many studies in Arabidopsis have revealed that the APETALA2 (AP2) gene is implicated in the establishment of floral meristem and floral organ identity as well as temporal and spatial regulation of flower homeotic gene expression.
