Genetic polymorphism of histone H1.z in duck erythrocytes

Biochemical Journal (1993)

Jan Pałyga Ewa Górnicka‐Michalska Andrzej Kowalski

Three different phenotypes of erythrocyte histone H1.z were detected in several lines of duck by using two-dimensional PAGE. Electrophoresis and inheritance data have shown that two co-dominant alleles, z1 and z2, encode two proteins which differ slightly in their apparent molecular masses. Allele z1 was very abundant and was found at a frequency at least 0.94, while allele z2 was very rare and was present at a frequency of less than 0.06. Limited chemical and enzymic cleavages appeared to indicate that the allelic forms of histone H1.z differed in the C-terminal regions of their molecules.

Linker Histone H1.b is Polymorphic in Grey Partridge (Perdix perdix)

Zeitschrift für Naturforschung C (2011)

Andrzej Kowalski Jan Pałyga Ewa Górnicka‐Michalska

This study was aimed at characterizing allelic variations of erythrocyte histone H1.b by comparing the electrophoretic patterns of histone H1.b from individuals of grey partridge (Perdix perdix) population. As two alloforms, H1.b1 and H1.b2, were discerned in the screening gels, the histone H1.b was regarded to be a polymorphic protein encoded by a gene with two codominant alleles, b1 and b2, at a locus. The tested population was found to be at Hardy-Weinberg equilibrium (chi2 = 0.834, p = 0.361), with only a minor heterozygote deficiency (fixation index F = 0.136). Since the histone H1.b alloforms were identified in a two-dimensional gel containing sodium dodecyl sulfate, with no significant differences in their migration pattern in an one-dimensional acetic acid polyacrylamide gel, we assumed that the H1.b alloforms possessed a similar net charge and differed in their apparent molecular weights. A comparison of N-bromosuccinimide-cleaved and alpha-chymotrypsin-digested products of histone H1.b alloforms revealed slight differences in the velocity of C-terminal peptides and a similarity in migration of their N-terminal peptides in one-dimensional sodium dodecyl sulfate-polyacrylamide gel. Therefore, it seemed that the histone H1.b alloforms might differ in this amino acid sequence in a protein segment between N-bromosuccinimide cleavage site and the very C-terminus.

Results from London's Distance-Based Charging Trials

15th World Congress on Intelligent Transport Systems and ITS America's 2008 Annual MeetingITS AmericaERTICOITS JapanTransCore (2008)

Nicholas O Williams Andrzej Kowalski

These trials aimed to investigate the feasibility of introducing alternative distance-based charging schemes to operate within London’s extended Congestion Charging Zone. The trials aimed to study: the feasibility of gathering journey/charging data under real conditions, the ability to OBUs to report journey data, vendors to support volunteers in Central London and journey patterns inside Central London. These latest trials used 500+ volunteer drivers going about their normal day to day business and driving routes and in ways which were unknown a priori to the trials team. Earlier trials used dedicated drivers, routes and trials infrastructure to gather data, whilst here existing vendors’ infrastructure was employed. Over three months, valuable data were obtained on driver patterns by route, distance, time of day and class of vehicle and provided insightful information on the capabilities of GNSS based systems.

A variety-specific arrangement of histone H1 subtype (H1.b and H1.z) polymorphic variants in differently plumaged quails

British Poultry Science (2020)

Andrzej Kowalski Sebastian Knaga

1. This study was undertaken to evaluate genetic diversity among three varieties of Japanese quail (British Range, English White and Tuxedo) differing in plumage colour. The level of genetic variation was rated through the histone H1 polymorphic loci (H1.b and H1.z) containing quantitatively similar (P > 0.05) isoforms (H1.b1, H1.b2 and H1.z1, H1.z2) that form both homozygous (b1, b2 and z1, z2) and heterozygous (b1b2 and z1z2) phenotypes.2. The complete set of histone H1 phenotypes were characteristic of the British Range and Tuxedo varieties. Phenotypes b2 and z2 were not detected in the English White variety. A lack of the former phenotypes resulted in excess of heterozygotes at loci H1.b (F = −0.563) and H1.z (F = −0.562), pointing to the presence of outbreeding.3. The English White variety deviated from Hardy–Weinberg proportions (H1.b – Χ2 = 7.61, P < 0.05 and H1.z – Χ2 = 5.84, P < 0.05), in contrast to the British Range variety (H1.b – Χ2 = 0.86, P > 0.05 and H1.z – Χ2 = 0.86, P > 0.05) and Tuxedo (H1.b – Χ2 = 1.6, P > 0.05 and H1.z – Χ2 = 1.6, P > 0.05). The estimated values of the FST index for loci H1.b (0.073) and H1.z (0.099) indicate a moderate genetic diversity of the quail population.4. The distinct array and distribution of histone H1 phenotypes among quail varieties suggested that histone H1 allelic variants might have an individual impact on characteristic pigmentation of poultry.
