Transcriptional profiling of wheat and wheat-rye addition lines to identify candidate genes for aluminum tolerance
A large-scale expression profiling study was performed to investigate candidate genes associated with the two quantitative trait loci for aluminum (Al) tolerance (Alt1 and Alt2). They have been identified in r...

Characterization, genetic diversity, phylogenetic relationships, and expression of the aluminum tolerance MATE1 gene in Secale species
Aluminum (Al) is the main limiting factor for crop production in acidic soils. Efflux of organic acids is one of the mechanisms that determine Al-tolerance, and an Al-activated citrate transporter (multidrug a...

The ScAACT1 gene at the Q alt5 locus as a candidate for increased aluminum tolerance in rye (Secale cereale L.)
Soluble aluminum (Al3+) is a major constraint to plant growth in highly acidic soils, which comprise up to 50% of the world’s arable land. The primary mechanism of Al resistance described in plants is the chelati...

From the rye Alt3 and Alt4 aluminum tolerance loci to orthologous genes in other cereals
The major limit to plant growth in acid soils is the presence of toxic aluminum (Al) cations, which limit growth by inhibiting root elongation. Aluminum tolerance in rye is controlled by (at least) four indepe...

Characterization of sequence polymorphisms from microsatellite flanking regions in Vitis spp
Single nucleotide polymorphisms or SNPs are the most abundant form of genetic variation in the genome of plants and animals. Microsatellites are hypervariable regions of genome, while their flanking regions ar...

Candidate gene identification of an aluminum-activated organic acid transporter gene at the Alt4 locus for aluminum tolerance in rye (Secale cereale L.)
Among cereal crops, rye is one of the most tolerant species to aluminum. A candidate gene approach was used to determine the likely molecular identity of an Al tolerance locus (Alt4). Using PCR primers designed f...

Some Homogeneous Rings Associated to Finite Morphisms
In this article we present a new technique to handle the study of homogeneous rings of a projective variety endowed with a finite or a generically finite morphism to another variety Y whose geometry is easier to ...

Optimising The Size of Sampling Units in an Area Frame
Area frame sampling is an important tool for area change estimation in agricultural and environmental problems. The cost-efficiency of the unit size chosen for the survey can be assessed through the intraclust...

Molecular markers linked to the aluminium tolerance gene Alt1 in rye (Secale cereale L.)
Rye has one of the most efficient group of genes for aluminium (Al) tolerance among cultivated species of Triticeae. This tolerance is controlled by at least two independent and dominant loci (Alt1 and Alt3) loc...

Chromosomal location of PCR fragments as a source of DNA markers linked to aluminium tolerance genes in rye
To identify and locate rye DNA sequences homologous to three wheat c-DNAs (wali1, wali2 and wali5) whose expression is induced by aluminium (Al) stress, we designed three pairs of specific primers. They were used...

Genetic control of aluminium tolerance in rye (Secale cereale L.)
Aluminium (Al) tolerance in roots of two cultivars (“Ailés” and “JNK”) and two inbred lines (“Riodeva” and “Pool”) of rye was studied using intact roots immersed in a nutrient solution at a controlled pH and ...

A map of rye chromosome 4R with cytological and isozyme markers
The progeny of two crosses between a structural heterozygote for a reciprocal translocation (4RL/5RL) and a homozygote for the standard chromosome arrangement and of four crosses between standard chromosome ho...

Rapid identification of Triticeae genotypes from single seeds using the polymerase chain reaction
An easy and quick protocol has been developed for DNA analysis via PCR. Single cereal endosperm or small leaf pieces can be separately processed in several PCR reactions. The resultant PCR patterns are equival...

NADH dehydrogenase: a new molecular marker for homoeology group 4 in Triticeae. A map of the 4RS chromosome arm in rye
Structural gene loci encoding the monomeric isozymes nicotin adenin dinucleotide dehydrogenase (NADH dehydrogenase or NDH) have been located on the 4AL, 4Bα, and 4DS chromosome arms of Triticum aestivum cv “Chine...

Biochemical evidence of a translocation between 6 RL/7 RL chromosome arms in rye (Secale cereale L.). A genetic map of 6R chromosome
The segregation of different isozymic loci was investigated in backcrosses and F2s in rye. The leucin aminopeptidase-1 (Lap-1), Aconitase-1 (Aco-1), Esterase-6 (Est-6), Esterase-8 (Est-8), and Endopeptidase-1 (Ep...

A map of rye chromosome 2R using isozyme and morphological markers
The segregation of isozymic loci for leaf peroxidases (L2Per) has been investigated in backcrosses and F2 offspring of rye lines having purple seeds (Ps) and monstrosum ears (mo). The Ps, L2Per-3b, mo, and L2Per-...

Chromosomal location of adenylate kinase isozymes in Triticeae species
One system of monomeric adenylate kinase isozymes, designated ADK, was observed in Triticum aestivum and in five diploid Triticeae species. The gene loci Adk-a, Adk-b and Adk-d were located on 7AL, 7BL and 7DL Tr...
