“…Thus, a candidate gene for the QTL at ~ 165 Mb could be GRMZM2G031200, which is located ~ 0.3 Mb away from the significant SNP and is a NAC transcription factor involved in secondary cell wall biosynthesis [68]. One possible candidate gene for the QTL at 150 is the laccase gene GRMZM2G146152, orthologous to AtLac17 that affects lignin content [65] and is located ~ 0.7 Mb away from the significant SNP. Regarding the genes in the region of the QTL at ~ 155 Mb, GRMZM2G140817 (C3H2) is located ~ 0.4 Mb distant from the significant SNP and is related to C3H1 that controls the phenylpropanoid flux.…”

BackgroundCorn borers constitute an important pest of maize around the world; in particular Sesamia nonagrioides Lefèbvre, named Mediterranean corn borer (MCB), causes important losses in Southern Europe. Methods of selection can be combined with transgenic approaches to increase the efficiency and durability of the resistance to corn borers. Previous studies of the genetic factors involved in resistance to MCB have been carried out using bi-parental populations that have low resolution or using association inbred panels that have a low power to detect rare alleles. We developed a Multi-parent Advanced Generation InterCrosses (MAGIC) population to map with high resolution the genetic determinants of resistance to MCB.ResultsWe detected multiple single nucleotide polymorphisms (SNPs) of low effect associated with resistance to stalk tunneling by MCB. We dissected a wide region related to stalk tunneling in multiple studies into three smaller regions (at ~ 150, ~ 155, and ~ 165 Mb in chromosome 6) that closely overlap with regions associated with cell wall composition. We also detected regions associated with kernel resistance and agronomic traits, although the co-localization of significant regions between traits was very low. This indicates that it is possible the concurrent improvement of resistance and agronomic traits.ConclusionsWe developed a mapping population which allowed a finer dissection of the genetics of maize resistance to corn borers and a solid nomination of candidate genes based on functional information. The population, given its large variability, was also adequate to map multiple traits and study the relationship between them.

“…However, this step would require the conversion of feruloylCoA to coniferaldehyde by CCR, which is expressed at a relatively low level in the pericarp. Ferulic acid might result from the transformation of caffeic acid by the action of an O-methyl transferase (OMT), either a COMT or another OMT, possibly a ZRP4-type OMT (Barrière et al, 2016 ). We identified maize proteins sharing sequence similarity with AtCSE (caffeoyl shikimate esterase) (Vanholme et al, 2013 ) that converts caffeoyl shikimic acid into caffeic acid.…”

“…The genes investigated here correspond to an updated list of maize genes established by Courtial et al ( 2013 ) and Barrière et al ( 2016 ) with a focus on genes potentially encoding enzymes involved in the synthesis and radical coupling of feruloylated arabinoxylans and monolignols. Maize orthologs to genes whose functions are known in other species were identified by a sequence similarity search based on protein sequences using the BlastP tool of the MaizeGDB with e-value lower than e-75 (Courtial et al, 2013 ).…”

“…In this report, the feruloylated arabinoxylan content of grain tissues (pericarp and endosperm) from the maize B73 line was measured and compared with those of 18 other maize lines. We determined the stages of development where the deposition of feruloylated arabinoxylans occurs in B73 grains, and we have used published and publicly available data to monitor the expression of genes associated with feruloylated arabinoxylan and lignin (Sekhon et al, 2011 ; Courtial et al, 2013 ; Barrière et al, 2016 ). Our study of maize pericarp highlights the expression of cell wall genes involved in the synthesis of feruloylated arabinoxylans, and as a consequence, we propose several robust candidate genes involved in ferulate and arabinoxylan synthesis and in the feruloylation and the cross-linking of xylans.…”

Cell walls are comprised of networks of entangled polymers that differ considerably between species, tissues and developmental stages. The cell walls of grasses, a family that encompasses major crops, contain specific polysaccharide structures such as xylans substituted with feruloylated arabinose residues. Ferulic acid is involved in the grass cell wall assembly by mediating linkages between xylan chains and between xylans and lignins. Ferulic acid contributes to the physical properties of cell walls, it is a hindrance to cell wall degradability (thus biomass conversion and silage digestibility) and may contribute to pest resistance. Many steps leading to the formation of grass xylans and their cross-linkages remain elusive. One explanation might originate from the fact that many studies were performed on lignified stem tissues. Pathways leading to lignins and feruloylated xylans share several steps, and lignin may impede the release and thus the quantification of ferulic acid. To overcome these difficulties, we used the pericarp of the maize B73 line as a model to study feruloylated xylan synthesis and crosslinking. Using Fourier-transform infra-red spectroscopy and biochemical analyses, we show that this tissue has a low lignin content and is composed of approximately 50% heteroxylans and approximately 5% ferulic acid. Our study shows that, to date, maize pericarp contains the highest level of ferulic acid reported in plant tissue. The detection of feruloylated xylans with a polyclonal antibody shows that the occurrence of these polysaccharides is developmentally regulated in maize grain. We used the genomic tools publicly available for the B73 line to study the expression of genes within families involved or suggested to be involved in the phenylpropanoid pathway, xylan formation, feruloylation and their oxidative crosslinking. Our analysis supports the hypothesis that the feruloylated moiety of xylans originated from feruloylCoA and is transferred by a member of the BAHD acyltransferase family. We propose candidate genes for functional characterization that could subsequently be targeted for grass crop breeding.

“…Maize crop is important in terms of its total production that is estimated around 800 million tons per year, and is widely distributed cereal after wheat and rice (Nafziger, 2010). Most maize grain produced is used as animal feed; and as raw material for many industrial uses, including bio-fuel production (Helander et al, 2015;Barrière et al, 2016). Maize is rich in carbohydrate, and good in protein and crude fiber content (Qamar et al, 2017).…”

Jordan Valley is considered as one of the main intensified irrigated agricultural areas in Jordan with high use of fertilizers especially of nitrogen source which lead to increased ground water pollution with nitrate. A field trial was conducted at the National Agricultural Research Center in Jordan Valley, North West Amman. Six soil treatments with organic cattle manure at the following rates were applied in summer 2014 and 2015: 0 (control), 8, 12, 16 and 20 tons ha −1. Treatments were arranged in a completely randomized block design using four replicates. Nitrogen fertilizer from ammonium sulphate, as source of nitrogen, labeled with 1% 15 N isotope was added at a rate of 75 kg ha −1. The objective of this study was to evaluate the effect of different rates of organic cattle manure on nitrogen uptake from ammonium sulphate fertilizer by grains of maize (Zea mays L.) plants using 15 N isotope-tracer technology. It was found that nitrogen use efficiency was decreased as the amount of applied cattle manure increased owing to the high competition of organic versus mineral nitrogen. Whereas cattle manure positively affected the uptake of Zn, Fe and Cu by maize grains, causing increased mineral uptake instances, the uptake of K, P and Ca was not or slightly affected by cattle manure at various levels. The results of the present study could be beneficial for the development of an efficient fertilization schedule that would satisfy maize plant requirement of major elements, in particular N without its accumulation in the soil and the subsequent hazards to environment.
