Transcriptomic analysis of maize developing earshoot, IBMRIL X IHP1 hybrid

ABSTRACT: Maize earshoot is a metabolic sink espcially related to nitrogen metabolism. Studies on the transcriptomic and metabolic changes occuring in earshoot can provide interesting answers about the nitrogen metabolic potential of the maize variety under study. Intermated B73 X Mo17 recombinant inbred lines (IBMRIL) belong to a predominantly used mapping population. Illinois high protein (IHP) line is a metabolic extreme with respect to nitrogen mebolism with around 30% seed protein. Developing earshoots from this genotype grown at nitrogen-deficient and nitrogen-sufficient conditions were sampled, processed and analyzed through microarray technology. IBMRIL population was crossed to IHP to find the allelic interaction related to nitrogen metabolism. Microarray experiment was conducted using the developing earshoots from IBMRIL X IHP1 lines that deffered in their grain yield significantly. Keywords: Yield response Technical replicates, dye swaps, technical replicates of dye swaps, no biological replicates

Genetic factors that respond to N in maize leaf tissue

Project description:Genotype and nitrogen-dosage effect on maize leaves collected at V8 leaf stage B73 is a model maize genotype while Illinois high protein line (IHP) is a metabolic extreme selected for higher grain protein concentration. It is a well known fact that the leaves serve as source and earshoot as a sink. Microarray analysis of V8 leaf collected from B73 and IHP genotypes grown at vairable nitrogen applications.

Transcriptomic analysis of maize developing earshoot from tropical maize hybrid genotypes native to Nigeria

Project description:Tropical maize genotypes are well known for their traits of late flowering and higher biomass. Carbon/Nitrogen balance in these genotypes is significantly different from temperate genotypes. Microarray analysis of gene expression changes occuring in developing earshoots was done and results were compared with the temperate genotype microarray analysis, previously conducted. A low yielding variety was used as a reference against three high yielding varities. Keywords: Genotype response Technical replicates, dye swaps, technical replicates of dye swaps, no biological replicates

ZmNRT1.1B (ZmNPF6.6) determines nitrogen use efficiency via regulation of nitrate transport and assimilation in maize

Project description:Nitrate (NO3-) is crucial for optimal plant growth and development and often limits crop productivity at the low availability. In comparison with model plant Arabidopsis, the molecular mechanisms underlying NO3- acquisition and utilization remain largely unclear in maize. In particular, only a few genes have been exploited to improve nitrogen use efficiency (NUE). Here, we demonstrated that NO3--inducible ZmNRT1.1B (ZmNPF6.6) positively regulated NO3--dependent growth and NUE in maize. We showed that the tandem duplicated proteoform ZmNRT1.1C is irrelevant to maize seedling growth under nitrate supply, however, loss-of-function of ZmNRT1.1B significantly weakened plant growth under adequate NO3- supply in both hydroponic and field conditions. 15N-labeled NO3- absorption assay indicated that ZmNRT1.1B mediated high-affinity NO3--transport and root-to-shoot NO3- translocation. Furthermore, upon NO3- supply, ZmNRT1.1B promotes cytoplasmic-to-nuclear shuttling of ZmNLP3.1 (ZmNLP8), which co-regulates the expression of genes involved in NO3- response, cytokinin biosynthesis and carbon metabolism. Remarkably, overexpression of ZmNRT1.1B in modern maize hybrids improved grain yield under nitrogen (N) limiting fields. Taken together, our study revealed a crucial role of ZmNRT1.1B in high-affinity NO3- transport and signaling and offers valuable genetic resource for breeding nitrogen use efficient high-yield cultivars.
