Genetic relationships between local Brazilian goat breeds based on mtDNA D-loop region similarity

Abstract

Aim of study: Our objective was to investigate the mitochondrial DNA of local Brazilian goats to gain insights into the genetic composition of this precious genetic resource.Area of study: The study was developed in BrazilMaterial and methods: We analyzed a hypervariable region of the mitochondrial DNA of 83 goats belonging to four local Brazilian breeds, including Canindé (CAN-RN), Moxotó (MOX-CE), Marota (MAR-PI) and Azul (AZU-PE) as well as of exotic breeds raised in different states of the Federation. Sequences related to local Brazilian goats showed a dispersed distribution throughout the median-joining network, and clustering with sequences of exotic breeds occurred in some haplotypes. The obtained sequences were analyzed and compared with different haplogroups (A, B1, B2, C, D, F, and G) available on GenBank.Main results: The local Brazilian goat breeds showed significant diversity, with 16 (0.8240) haplotypes. Population structure analysis revealed substantial differences among breeds (p < 0.05). Mitochondrial lineage A was observed in Brazilian goats. Phylogeny showed European goats as the dominant stock for Brazilian goats, but there weare some haplotypes within haplogroup A, clustering with African and Asian haplotypes.Research highlights: These results could be suitable for creating a strategic conservation program, potentially benefitting future breeding programs.

Genetic Divergence of Local Goats in Ninh Thuan Province Vietnam

“…Many studies reported lineage A as an old lineage, widely distributed in Asian, European and African goat breeds (Pereira et al, 2005;Royo et al, 2009;Vacca et al, 2010). Recently, investigations of domestic goats in Brazil (Silva et al, 2019) and Arabia (Al-Araimi et al, 2017) reported that most belonged to maternal lineage A. More than 90% of the world's goats were identified as belonging to lineage A (Wang et al, 2015;Deng et al, 2018;Ganbold et al, 2020;Nguluma et al, 2021).…”

Recursos Genéticos De Caprinos: Cenário E Sustentabilidade

“…As pesquisas retratam caprinos das raças locais: Moxotó, Azul, Canindé, Repartida, Marota e Graúna, os estudos ocorreram no Nordeste do Brasil (GINJA et al, 2017;MENEZES et al, 2020;MOURA et al, 2019;NERI et al, 2018;PAIM et al, 2019;SILVA et al,2019).…”

“…A grande variedade de cabras locais representa um importante reservatório genético e que áreas distantes dos centros de domesticação apresenta uma diversidade genética significativa que pode beneficiar os programas de conservação (SILVA et al, 2019). Os autores continuam descrevendo que esses resultados podem ser adequados para a criação de um programa de conservação estratégico, potencialmente beneficiando futuros programas de melhoramento.…”

Diversity Analysis and Genetic Relationships among Local Brazilian Goat Breeds Using SSR Markers

“…The genetic makeup of the Brazilian goat breeds has been influenced by breeds of the Iberian Peninsula and even West African [ 21 , 30 , 31 , 32 ], promoting gene flow between the Iberian Peninsula, northern Africa, and the Canary Islands and Cape Verde [ 33 , 34 , 35 ]. Currently, Brazilian goat breeds are genetically distinct with a clear differentiation even from their possible ancestors [ 1 , 6 , 36 , 37 , 38 ]…”

“…The genetic makeup of the Brazilian goat breeds has been influenced by breeds of the Iberian Peninsula and even West African [21,[30][31][32], promoting gene flow between the Iberian Peninsula, northern Africa, and the Canary Islands and Cape Verde [33][34][35]. Currently, Brazilian goat breeds are genetically distinct with a clear differentiation even from their possible ancestors [1,6,[36][37][38] As pointed out before, the Brazilian goat herds are very concentrated in one specific region, so that gene flow among breeds must be shared, especially considering that the herd book is either not ongoing or is very rudimentary.…”
