REPRODUCTIVE ISOLATION OF TRITICUM BOEOTICUM AND TRITICUM URARTU AND THE ORIGIN OF THE TETRAPLOID WHEATS

American Journal of Botany, 1976
The diploid wheats Triticum boeoticum and T. urartu are sympatric with one another throughout the geographic range of the wild tetraploids. Reciprocal crosses between ecogeographic types within each diploid species gave viable seed, but interspecific crosses consistently gave viable seed only when T. boeoticum was the female parent.

Genetic diversity in wild diploid wheats Triticum monococcum var. boeoticum and T. urartu (Poaceae)

Theoretical and Applied Genetics, 1989
The genetic diversity of two wild diploid wheat species, Triticum monococcum var. boeoticum and T. urartu, was assessed using starch gel electrophoresis. Genetic diversity is uniformly low in both species. Number of alleles per locus was very low with a mean of 1.22 for T. monococcum var. boeoticum and 1.19 in T. urartu.

Diversity and distribution of Rc1 alleles in Triticum urartu from the Middle East

Genetic Resources and Crop Evolution, 2017
Rc1 (red coleoptile) encode a R2R3-MYB transcription factor TaMYB-A1 in common wheat, but the homologous genes have not been reported in Triticum urartu or Triticum monococcum, both species being sources of the ancient A genome. In this study, four alleles were discovered in 120 T. urartu accessions, and two alleles from nine T.

Triticum urartu MTP1: its ability to maintain Zn2+ and Co2+ homeostasis and metal selectivity determinants

Plant Cell Reports, 2018
TuMTP1 maintains Zn2+ and Co2+ homeostasis by sequestering excess Zn2+ and Co2+ into vacuoles. The mutations NSEDD/VTVTT in the His-rich loop and I119F in TMD3 of TuMTP1 restrict metal selectivity. Mineral nutrients, such as zinc (Zn) and cobalt (Co), are essential or beneficial for plants but can be toxic at elevated levels.

Genetic variability of the wild diploid wheat Triticum urartu revealed by RFLP and RAPD markers

Theoretical and Applied Genetics, 1997
Genetic variability among 49 accessions of Triticum urartu was estimated by RFLP and RAPD marker analyses, and the two data sets were compared. One T. timopheevii accession and two accessions of T. durum and T. aestivum, respectively, were included to identify T. urartu accessions closely related to these polyploid wheats.
