Transcriptome-wide association study and eQTL analysis to assess the genetic basis of bulb-yield traits in garlic (Allium sativum).

ABSTRACT:

Background

Garlic bulbs are abnormal expanding axillary buds that are rarely found among vascular plants. Bulb-yield is one of the valuable agronomic traits of garlic. However, due to the large genome size and a strictly asexual life cycle in the cultivars, the genetic basis of the yield traits are poorly understood in garlic.

Results

In the present study, we carried out an association mapping for three yield traits of garlic bulbs: bulb weight (BW), diameter (BD), and the number of garlic cloves (CN), using the recently proposed transcriptome-referenced association study. In total 25, 2, and 30 single nucleotide polymorphisms (SNPs), were identified in the transcripts to be associated with BW, BD, and CN traits, respectively. Of the transcripts with associated SNPs, the exp
