“…Genome-wide association study (GWAS) is often referred as a "hypothesis-generating" analysis and could serve as a first step to gaining novel understanding of mechanisms of NUE by studying genetic variations of the entire genome instead of only targeting specified genes of interest (Ali et al, 2021;Özdemir et al, 2021). Although numerous above-ground crop traits have been determined to be closely correlated with NUE as well as identifying associated genes conferring high NUE in pre-breeding research (Yang et al, 2014;Han et al, 2016;Karunarathne et al, 2020a), a great study gap is present in relevant below-ground activities due to difficulties in phenotyping root traits under field conditions and dynamics in soil N status (Garnett et al, 2009;Plett et al, 2020).…”

Nitrogen (N) fertilizer is one of the major inputs for grain crops including barley and its usage is increasing globally. However, N use efficiency (NUE) is low in cereal crops, leading to higher production costs, unfulfilled grain yield potential and environmental hazards. N uptake is initiated from plant root tips but a very limited number of studies have been conducted on roots relevant to NUE specifically. In this review, we used barley, the fourth most important cereal crop, as the primary study plant to investigate this topic. We first highlighted the recent progress and study gaps in genetic analysis results, primarily, the genome-wide association study (GWAS) regarding both biological and statistical considerations. In addition, different factors contributing to NUE are discussed in terms of root morphological and anatomical traits, as well as physiological mechanisms such as N transporter activities and hormonal regulation.
