Electrical Capacitance versus Minirhizotron Technique: A Study of Root Dynamics in Wheat-Pea Intercrops.

This study evaluated the concurrent application and the results of the root electrical capacitance (C) and minirhizotron (MR) methods in the same plant populations. The container experiment involved three winter wheat cultivars, grown as sole crops or intercropped with winter pea under well-watered or drought-stressed conditions. The wheat root activity (characterized by C) and the MR-based root length (RL) and root surface area (RSA) were monitored during the vegetation period, the flag leaf chlorophyll content was measured at flowering, and the wheat shoot dry mass (SDM) and grain yield (GY) were determined at maturity.

Development of a New A -Genome-Specific Single Nucleotide Polymorphism Marker Set for the Molecular Characterization of Wheat-Triticum monococcum Introgression Lines.

We identified 1247 polymorphic single nucleotide polymorphisms between Triticum monococcum and wheat. We identified 191 markers validated across all seven chromosomes of T. monococcum.

Unlocking the Genetic Diversity and Population Structure of a Wild Gene Source of Wheat, , and Its Relationship With the Heading Time.

Understanding the genetic diversity of , a valuable source of agronomical useful genes, may significantly facilitate the introgression breeding of wheat. The genetic diversity and population structure of 86 genotypes were investigated by 32700 DArT markers with the simultaneous application of three statistical methods- neighbor-joining clustering, Principal Coordinate Analysis, and the Bayesian approach to classification. The collection of accessions was divided into five groups that correlated well with their eco-geographic habitat: A (North Africa), B (mainly from Balkans), C (Kosovo and Near East), D (Turkey, Crimea, and Peloponnese), and E (Azerbaijan and the Levant region).

Cytomolecular discrimination of the A chromosomes of Triticum monococcum and the A chromosomes of Triticum aestivum using microsatellite DNA repeats.

The cytomolecular discrimination of the A- and A-genome chromosomes facilitates the selection of wheat-Triticum monococcum introgression lines. Fluorescence in situ hybridisation (FISH) with the commonly used DNA probes Afa family, 18S rDNA and pSc119.2 showed that the more complex hybridisation pattern obtained in T.

Molecular cytogenetic identification and phenotypic description of a new synthetic amphiploid, (AAGGAA).

Flow cytometric chromosome sorting from diploid progenitors of bread wheat, T. urartu, Ae. speltoides and Ae. tauschii.

Chromosomes 5A (u) , 5S and 5D can be isolated from wild progenitors, providing a chromosome-based approach to develop tools for breeding and to study the genome evolution of wheat. The three subgenomes of hexaploid bread wheat originated from Triticum urartu (A(u)A(u)), from a species similar to Aegilops speltoides (SS) (progenitor of the B genome), and from Ae. tauschii (DD).
