Linkage Disequilibrium (LD) Analysis in Alfalfa (Medicago sativa L.) Populations Spreading in Different Geographies of the World

Abstract

Cultivated alfalfa
(
Medicago sativa L.)
was derived from Medicago sativa
species complex as a result of breeding efforts.  New efforts have focused on to determine the
DNA polymorphisms based on molecular markers and to link these polymorphisms
with related phenotype recently. Especially, the relationships between
genotypes and phenotypes are evaluated as Linkage Analysis and Association
Mapping Studies. On the basis of information, in this study, Linkage
Disequilibrium (LD) analysis was also performed using 31 SSR markers for the 70
populations. For the LD analysis, 23 of the 31 markers identified the physical
distances on the 8 chromosomes of the alfalfa. Distances of 103 loci on 8
chromosomes were determined based on Medicago
truncatula
genome. A significant
(p<0,0001) LD value
was not observed in these populations for the evaluated markers.

Abstract

Kültür yoncası
(
Medicago sativa L.), ıslah
çalışmaları sonucunda Medicago sativa
tür kompleksinden geliştirilmiştir. Son zamanlarda, yonca bitkisindeki
çalışmaların moleküler markörler temelinde DNA polimorfizmlerini belirlemeye ve
bu polimorfizmlerle ilişkili olan fenotipler arasında bağlantı kurmaya
odaklandığı bilinmektedir. Özellikle genotipler ve fenotipler arasındaki
ilişkiler, Bağlantı Analizleri ve İlişki Haritalama çalışmaları şeklinde
değerlendirilmektedir. Bilgiler temelinde bu çalışmada; 70 populasyon için 31
SSR markörü kullanılarak Bağlantı Eşitsizliği (Linkage Disequilibrium, LD)
analizi de gerçekleştirilmiştir. Bağlantı Eşitsizliği analizi için; 31
markörden 23 tanesinin yonca’nın 8 kromozomu üzerindeki fiziksel mesafeleri
belirlenmiştir. 8 kromozom üzerinde 103 lokustan oluşan mesafeler Medicago truncatula genomu temel
alınarak saptanmıştır. Değerlendirilen markörler için; bu populasyonlarda
önemli
(p<0,0001) bir Bağlantı Eşitsizliği (LD) değeri gözlenmemiştir.
