Última Mapping aluminum tolerance loci in cereals: A tool available for crop breeding Electron. J. Biotechnol. Inostroza-Blancheteau,Claudio; Soto,Braulio; Ibáñez,Cristian; Ulloa,Pilar; Aquea,Felipe; Arce-Johnson,Patricio; Reyes-Díaz,Marjorie. Aluminum (Al) toxicity is the main factor limiting crop productivity in acidic soils around the world. In cereals, this problem reduces crop yields by 30-40%. The use of DNA-based markers linked to phenotypic traits is an interesting alternative approach. Strategies such as molecular marker-assisted selection (MAS) in conjunction with bioinformatics-based tools such as graphical genotypes (GGT) have been important for confirming introgression of genes or genomic regions in cereals but also to reduce the time and cost of identifying them through genetic selection. These biotechnologies also make it possible to identify target genes or quantitative trait loci (QTL) that can be potentially used in similar crops to increase their productivity. This review...

Suelo Nutr. Veg. Inostroza-Blancheteau,Claudio; Soto,Braulio; Ulloa,Pilar; Aquea,Felipe; Reyes-Diaz,Marjorie. Aluminum (Al) toxicity is one of the main factors limiting crop productivity in acid soils around the world. In cereals, this problem can affect between 30 and 40% of crop yields. One way to reduce the toxic effect of Al is to neutralize the acidity with calcareous amendments. However, this practice is demanding and not very effective. An alternative is the search for genetic variability in the genome of cropping grasses and/or their wild relatives to resist Al. The development of biotechnology and molecular genetics approach has facilitated the understanding of the physiological, genetic and molecular bases in the process of ameliorating these species. This review presents the main physiological mechanisms of Al resistance and the genetic and molecular...
