Excess nitrogen responsive HvMADS27 transcription factor controls barley root architecture by regulating abscisic acid level.

ABSTRACT: Nitrogen (N) is an important element for plant growth and development. Although several studies have examined plants' response to N deficiency, studies on plants' response to excess N, which is common in fertilizer-based agrosystems, are limited. Therefore, the aim of this study was to examine the response of barley to excess N conditions, specifically the root response. Additionally, genomic mechanism of excess N response in barley was elucidated using transcriptomic technologies. The results of the study showed that barley MADS27 transcription factor was mainly expressed in the roots and its gene contained N-responsive cis-regulatory elements in the promoter region. Additionally, there was a significant decrease in HvMADS27 expression under excess N condition; however, its
