TAILIEUCHUNG - Integrated physiologic, genomic and transcriptomic strategies involving the adaptation of allotetraploid rapeseed to nitrogen limitation

Nitrogen (N) is a macronutrient that is essential for optimal plant growth and seed yield. Allotetraploid rapeseed (AnAnCnCn, 2n = 4x = 38) has a higher requirement for N fertilizers whereas exhibiting a lower N use efficiency (NUE) than cereal crops. | Integrated physiologic genomic and transcriptomic strategies involving the adaptation of allotetraploid rapeseed to nitrogen limitation .den color inherit .ttnd ol .ttnd ul .ttnd dl padding 0 0px 0 20px .ttnd hr margin 10px 0px .ttnd a href javascript void 0 .ttnd a href color inherit dtextscript p text-align left dtextscript img vertical-align middle Zhang et al.

Allotetraploid lt br gt rapeseed AnAnCnCn 2n 4x 38 has a higher requirement for N fertilizers whereas exhibiting a lower N use efficiency lt br gt NUE than cereal crops. N limitation adaptation NLA is pivotal for enhancing crop NUE and reducing N fertilizer use lt br gt in yield production. Therefore revealing the genetic and molecular mechanisms underlying NLA is urgent for the lt br gt genetic improvement of NUE in rapeseed and other crop species with complex genomes. lt br gt Results In this study we integrated physiologic genomic and transcriptomic analyses to comprehensively characterize lt br gt the adaptive strategies of oilseed rape to N limitation stresses. Under N limitations we detected accumulated anthocyanin lt br gt reduced nitrate NO3 and total N concentrations and enhanced glutamine synthetase activity in the N-starved rapeseed lt br gt plants. High-throughput transcriptomics revealed that the pathways associated with N metabolism and carbon fixation lt br gt were highly .
