The examination of the genomic architecture of indigenous sheep in relation to climate change facilitates the identification of genetic diversity and adaptability hotspots, which can contribute to the enhancement of conservation efforts for animal genetic resources. Using ovine50K SNP chips of 832 samples from 32 breeds from various climatic zones, the genomic insight of native sheep breeds sampled from different climatic zones is presented, a finding that can be utilized in the development of climate specific adapted sheep breeds. Results of this study underscore that, although the breeds under study exhibit significant genetic diversity, there is an alarming decline in this diversity, as evidenced by the effective population size. African breeds distinctly positioned themselves on one facet of PCA 1, without any overlap, signifying their unique genomic structures. Conversely, European indigenous sheep breeds display a rich genetic variation; however, a pronounced admixture was noted in several breeds, compromising their genetic distinctiveness. While the studied breeds exhibited some levels of inbreeding, analysis runs of homozygosity (ROH) patterns suggest that these breeds past ancestral inbreeding events may be more influential than recent ones. This was shown by deficiency of long ROHs (24-48 and > 48 mb). Also, the ROH patterns showed that these breeds underwent different historical development stages. Over 400 genes were potentially linked to climate change adaptation. Intriguingly, the majority of these genes are exclusive to specific climate-based populations, underscoring the unique adaptive capacities inherent to each studied group. Notably, a significant proportion of these genes are associated with immune responses, emphasizing the imperative of breeding disease-resistant livestock in the current context of climate change. Analysis of landscape genomics revealed that rainfall and temperature are likely drivers of adaptation in these population. Interestingly, nine genes (HLF, ATP5MC2, SCD5, GSTA1, STAT1, TARBP2, ADIG, PLIN1, ABHD5) with diverse functions related to immunity, growth, and development were found to be located near SNPs that were significantly associated with these climatic variables. This study reinforces the notion that while indigenous sheep breeds retain substantial genetic diversity, it is diminishing, potentially due to suboptimal genetic management or admixture events. Furthermore, our findings highlight the innate capability of native sheep breeds to adapt to climatic change, positioning them as invaluable resources for breeding traits associated with climate resilience, thereby enhancing the overall robustness of sheep populations.Tétel Szabadon hozzáférhető Genomic diversity level and relationship of selected European indigenous sheep breedsSchroder Figueira, Leticia; Kusza, Szilvia; Wanjala, George; DE--Természettudományi és Technológiai Kar--Biológiai és Ökológiai IntézetThrough history, wars, famines, climatic events, and diseases have led to mass death of animals. To replenish this numbers, it was necessary that new animals were brough in from other places leading to the wide variety of breeds we see today. Sheep have been effectively adapted to a variety of habitats and to the specialized production through animal husbandry and directed mating. It is anticipated that selection will change the target population's allele frequencies for the functional mutations and any nearby SNPs (Single Nucleotide Polymorphism). As a result, the genetic study of sheep traits contributes to our understanding of biological processes in mammalian species as well as other species. The aim of this thesis is to understand the genetic relationship between selected European native sheep breeds from the analysis of medium density, genome wide SNPs markers.Tétel Szabadon hozzáférhető Heat Stress: Can Animals be Stressed but still be Healthy?(2023) Astuti, Putri Kusuma; Fajardo, Roland; Wanjala, George; Kichamu, Nelly; Ohran, Husein; Badaoui, Bouabid; Bagi, Zoltán; Kusza, SzilviaTétel Szabadon hozzáférhető Impacts of climate change on sheep genetic diversity: a review(2020) Wanjala, George; Bagi, Zoltán; Jávor, András; Kusza, SzilviaTétel Szabadon hozzáférhető Insights into the genomic homogeneity of Moroccan indigenous sheep breeds though the lens of runs of homozygosity(2024) Kusza, Szilvia; Badaoui, Bouabid; Wanjala, GeorgeTétel Korlátozottan hozzáférhető Lake Balaton as a geographical barrier for gene flow between wild boar populations in Hungary.Wanjala, George; Kusza, Szilvia; Mihalik, Bendegúz; DE--Mezőgazdaság- Élelmiszertudományi és Környezetgazdálkodási KarDespite of the large number of literature on genetic diversity of Sus scrofa in Europe, little is known about the genetic differences between wild boar populations in South (Kecel-Imrehegy) and Northern parts of Lake Balaton and the effect of the Lake to gene flow. Therefore, the study aims to establish genetic variability of wild boar populations between sampling site in Veszprém and Bács-Kiskun counties and to investigate effects of lake Balaton to gene flow. Earlier developed thirteen STR and sex identification microsatellite markers were used to amplify DNA isolated from 38 samples of wild boar populations between the hunting sites of Kecel-Imrehegy and North of Balaton (18 and 20, respectively). Result analysis showed low observes and Expected heterozygosity (Hobs=0.42±0.21 and H exp=0.45±0.25) and a low intrapopulation average gene diversity (Gdv= 0.35 and Gdv=0.4) for NorthBalaton and South Balaton Populations respectively. Plotting by PAST v2.17.c software failed to separate the two populations distinctively, however, it shows a small, non- significant difference. As expected we conclude that the two studied populations were genetically similar. This point out high gene flow between the populations despite being separated by Balaton and a long distance (150km apart) and hence no correlation between genetic and geographical distance.Tétel Szabadon hozzáférhető Leveraging Agri-advocacy to promote animal genetic diversity for climate change mitigation: Kenya and Tanzania perspective(2024) Wanjala, George; Pius, Lenox Omondi; Strausz, Péter; Kusza, Szilvia
