RNA-Seq-Based Transcriptome Profiling of Early Nitrogen Deficiency Response in Cucumber Seedlings Provides New Insight into the Putative Nitrogen Regulatory Network

Abstract: Nitrogen (N) is both an important macronutrient and a signal for plant growth and development. However, the early regulatory mechanism of plants in response to N starvation is not well understood, especially in cucumber, an economically important crop that normally consumes excessive N during production. In this study, the early time-course transcriptome response of cucumber leaves under N deficiency was monitored using RNA sequencing (RNA-Seq). More than 23,000 transcripts were examined in cucumber leaves, of… Show more

“…On the contrary, Trevisan et al (2011) reported that the BR receptor-like kinase BRI1 expression was down-regulated after 5 days of nitrate depletion in maize. Similarly, the BRI1 kinase inhibitor 1 gene BKI1, a negative regulator involved in the BR signaling pathway, was up-regulated under N deficiency in cucumber (Zhao et al 2015). These apparently conflicting data might be explained considering that BRs perform diverse functions by sharing signaling pathways with other phytohormones.…”

“…The NGS technology and particular RNA-seq methods started to be widely used for studying important breeding traits in cucumber (Table 1) such as fruit development [75,76], parthenocarpy [77], trichomes formation that function in plant defense against biotic and abiotic stresses [78], early regulatory mechanism of plants in response to N starvation and transcriptome response of cucumber leaves under N deficiency [79], mechanism of melatonin-induced lateral root formation in cucumber under salt stress [80] and also flower sex expression [81,82].…”

“…Genes coding for miR399 and miR530 are differentially expressed upon nitrogen starvation [440]. RNA-Seq analysis of nitrogen-deficient cucumber plants showed that 196 genes associated with photosynthesis and cell wall metabolism are down regulated while 168 genes associated with antioxidant synthesis, flavonoid and phenylpropanoid biosynthesis are up regulated [441].…”
