Allelic Variation of Puroindolines Genes in Iranian Common Wheat Landraces
Huertas-García, Ana B.; Guzmán, Carlos; Tabbita, Facundo; Álvarez, Juan B. (MDPI, 2022)Wheat is one of the most widely grown crops in the world. One of the traits that defines wheat quality is grain hardness, which is determined by puroindolines (PINA and PINB) proteins encoded with Pina-D1 and Pinb-D1 genes. ... -
Amylose content and starch properties in emmer and durum wheat lines with different waxy proteins composition
Guzmán, Carlos; Caballero, Leonor; Álvarez, Juan B.; Yamamori, Makoto (Wiley, 2011)BACKGROUND: Emmer wheat is a neglected crop that can be used in the breeding of modern durum wheat for quality. One important aspect of this quality is the starch composition, which is related to the waxy proteins. A ... -

Genetic variation for waxy proteins and amylose content in Spanish spelt wheat (Triticum spelta L.)
Guzmán, Carlos; Caballero, Leonor; Moral, Ana; Álvarez, Juan B. (Springer, 2010)Spelt wheat is a neglected crop that could be used in the quality breeding of modern common wheat. One important aspect of this quality is the starch composition which is related to the waxy proteins. A collection of 420 ... -

Martín, Ángela; Mattioni, Claudia; Molina, Juan Ramón; Álvarez, Juan B.; Cherubini, Marcello; Herrera Machuca, Miguel Ángel; Vilani, F.; Martín, Luis Miguel (Springer, 2011)The current need for forest conservation and management has driven a rapid expansion of landscape genetics approach. This discipline combines tools from molecular genetics, landscape ecology and spatial statistics and is ... -
Molecular characterisation of the Wx-B1 allelic variants identified in cultivated emmer wheat and comparison with those of durum wheat
Guzmán, Carlos; Caballero, Leonor; Álvarez, Juan B. (Springer, 2011)Emmer wheat is a neglected crop that could be used in the breeding of modern durum wheat for quality, one important aspect of which is the starch composition that is related to the waxy proteins. A collection of 87 accessions ... -
Molecular characterization and diversity of the Pina and Pinb genes in cultivated and wild diploid wheat
Guzmán, Carlos; Caballero, Leonor; Martín, Ángela; Álvarez, Juan B. (Springer, 2011)Grain hardness is one of the most important characteristics of wheat quality. Soft endosperm is associated with the presence of two proteins in the wild form, puroindoline a and b. The puroindoline genes and their derived ... -
Molecular characterization of a new waxy allele with partial expression in spelt wheat
Guzmán, Carlos; Caballero, Leonor; Yamamori, Makoto; Álvarez, Juan B. (Springer, 2012)Starch composition which is dependent on the waxy protein, the enzyme responsible for amylose synthesis in the grain, is an important aspect of the wheat quality. In this report, we describe the characterization of a novel ... -
Molecular characterization of a novel waxy allele (Wx-A u 1a) from Triticum urartu Thum. ex Gandil.
Guzmán, Carlos; Álvarez, Juan B. (Springer, 2012)Granule Bound Starch Synthase I, or waxy protein, is the sole enzyme responsible for the accumulation of amylose during the development of starch granules in wheat. The full coding region of the waxy (Wx) gene was sequenced ... -
Potential Use of Wild Einkorn Wheat for Wheat Grain Quality Improvement: Evaluation and Characterization of Glu-1, Wx and Ha Loci
Huertas-García, Ana B.; Castellano, Laura; Guzmán, Carlos; Álvarez, Juan B. (MDPI, 2021)Wild einkorn (Triticum monococcum L. ssp. aegilopoides (Link) Thell.) is a diploid wheat species from the Near East that has been classified as an ancestor of the first cultivated wheat (einkorn; T. monococcum L. ssp. ... -
