Genetical and physiological studies of gibberellic acid insensitivity in semidwarf rye

Hereditas (2008)

Andreas Börner G. Melz John R. Lenton

Because of the breeding value of gibberellic acid (GA3) insensitive semidwarf genotypes in wheat, a screening for GA3 response within a collection of semidwarf ryes was initiated and up to now four genotypes ('Moskowskij Karlik', 'Gülzow kurz', 'R18', 'Dwarf C) were found to be insensitive to applied gibberellic acid. In contrast to wheat, where all of the known alleles for GA insensitivity are (partially) dominant, the genetical studies did show that these four genotypes are carrying recessive alleles. Furthermore, it was found that the alleles of 'Moskowskij Karlik' and 'R18 seem to have the same locus on chromosome 5R, whereas the GA insensitivity of 'Gülzow kurz' and 'Dwarf C' is governed by two alleles of a different locus on chromosome 7R. None of the identified alleles was located on chromosome 4R, which could have been expected from the homoeologous relationships to wheat chromosomes 4B and 4D, which are critical for GA insensitivity. Studies on endogenous levels of gibberellins are in accordance with the genetical results, and suggest the GA insensitivity in rye to be caused by a different mechanism, compared to wheat.

Characterization of Hordeum vulgare – Hordeum bulbosum chromosome substitution lines by restriction fragment length polymorphism analysis

Genome (1993)

Gail M. Timmerman‐Vaughan R. A. Pickering G. Melz

Plants obtained from crosses between Hordeum vulgare and H. bulbosum were previously analyzed cytologically and for isozyme composition. They were identified as possessing substitutions of one or more H. vulgare chromosomes by their H. bulbosum homoeologues. To confirm their constitution and assess the merits of molecular techniques, chromosome-specific probes developed for the Triticeae were hybridized to Southern blots of DNA extracted from these plants and their parents. The hybridization patterns in the substitution plants confirmed that particular chromosomes of H. vulgare were replaced by their H. bulbosum homoeologues. For most probes, heterozygosity between pairs of H. bulbosum chromosomes was recorded. A possible duplication involving H. bulbosum homoeologues of barley chromosomes 4 and 7 was observed. Although molecular and cytological methods for analyzing chromosomally engineered plants are complementary, molecular probes may uncover differences not discernible using light microscopy or isozyme analysis.Key words: Hordeum vulgare, Hordeum bulbosum, chromosome substitutions, restriction fragment length polymorphism.

Identification of the Chromosomes in the ‘Esto’ Set of Rye Trisomics

Plant Breeding (1988)

G. Melz R. Schlegel J. Sybenga

Abstract The original identification of the chromosomes involved in each of the lines of the act of primary trisomics of winter rye variety ‘Esto’ does not correspond with recent results of gene localization studies. Using known morphological marker genes, N‐banding and test crossing with the standard translocation tester set, a more precise identification was possible. In the nomenclature of the Triticinae, the lines can be designated as follows: A = 7R; B = 5R; C = 2R; D = 3R; E = 4R; F = 6R; G = 1R.

Identification of the First Rye‐Cytoplasmic Rye‐Wheat‐Addition Using LAP‐Isozymes

V. Thiele R. Buschbeck A. Seidel G. Melz

Abstract Rye‐cytoplasmic rye‐wheat‐additions were produced by double backcrossing rye‐cytoplasmic tetraploid triticale with an inbred line of diploid rye cv. ‘Esto’. Addition 6B was identified using LAP‐isozymes.

Chromosomal location of genes controlling lactate dehydrogenase in rye, wheat, and barley

Genome (1992)

V. Thiele G. Melz

The chromosomal location of lactate dehydrogenease (LDH) genes in rye, barley, and wheat was investigated using the disomic standard addition sets of 'Chinese Spring' – 'Imperial' (wheat–rye) and 'Chinese Spring' – 'Betzes (wheat–barley) and the monosomic rye–wheat additions, respectively. Gel electrophoresis was performed on 5% polyacrylamide gels. Diagnostic bands for LDH isozymes were present only in zone 2. Genes controlling LDH isozymes in rye were found to be located on rye chromosome 4R (Ldh-R1and Ldh-R2) and in barley on chromosome 4H v (Ldh-H1 and Ldh-H2). Because of the incomplete rye–wheat addition set, only one gene for LDH isozymes of wheat could be located (wheat chromosome 4B; Ldh-B1). In the three cereal species investigated, LDH genes are located generally on homoeologous group 4 chromosomes.Key words: gene location, lactate dehydrogenase, Secale cereale, Triticum aestivum, Hordeum vulgare.
