Kernel weight is a critical factor that essentially affects maize (Zea mays) yield. In natural inbred lines, popcorn kernels exhibit overtly smaller sizes compared to dent corn kernels, and kernel weight, which controlled by multiple genetic loci, varies widely. Here, we characterized major quantitative trait locus on chromosome 1, responsible for controlling (qKW1) size. The qKW1 encodes protein containing seven in absentia domain with E3 ubiquitin ligase activity, expressed prominently...
Grain oil content is negatively correlated with starch in maize general. In this study, 282 and 263 recombinant inbred lines (RIL) developed from two crosses between one high-oil normal dent inbreds were evaluated for grain its correlation under four environments. Single-trait QTL single-population joint-population analysis, multiple-trait both detected, compared the result obtained related F2∶3 populations. Totally, 20 detected. No was simultaneously detected across all ten cases. at bins...
Abstract Popping volume (PV), flake size (FS) and popping rate (PR) are three important characteristics in popcorn ( Zea mays L.). We developed 259 F 2:3 lines from a cross between dent corn inbred ‘Dan232’ ‘N04’ that were grown during spring summer to evaluate the characteristics. Fifteen quantitative trait loci (QTL) detected on chromosomes 1, 2, 5, 6, 7 8 using composite interval mapping. The numbers of QTL 4 5 for PV, FS PR, respectively, with phenotypic variance explained ranging 4.9%...
Kernel weight is a critical agronomic trait in maize production. Many genes are related to kernel but only few of them have been applied breeding and cultivation. Here, we identify novel function mitogen-activated protein kinase 6 (ZmMPK6) the regulation weight. was reduced zmmpk6 mutants increased ZmMPK6-overexpressing lines. In addition, starch granules, content, grain-filling characteristics were also affected by ZmMPK6 expression level. mainly localized nucleus cytoplasm, widely...
Plant height (PH) is one of the most important traits in maize breeding programs. In popcorn, inferior plant can be improved with dent/flint corn germplasm. current study, a total 259 F2:3 families, developed from cross between dent inbred and popcorn inbred, were evaluated for 4 PH traits. Quantitative trait loci (QTLs) each detected using composite interval mapping methods. addition, genetic interrelationships investigated multiple-trait joint analysis ear (EH), top (TH). total, 6, 5, 2, 6...
ADP ‐ribosylation factors ( ARFs ) are small GTP ‐binding proteins that regulate a wide variety of cell functions. Previously, we isolated new ARF , ZmArf2 from maize Zea mays ). Sequence and expression characteristics indicated might play critical role in the early stages endosperm development. In this study, investigated function by analysis its activity subcellular localization. We also over‐expressed Arabidopsis measured organ size counted numbers. The levels five size‐associated genes...
As a newly identified category of DNA transposon, helitrons have been found in large number eukaryotes genomes. Helitrons contributed significantly to the intra-specific genome diversity maize. Although many characteristics maize well documented, sequence an intact autonomous has not In addition, process gene fragment capturing during transposition characterized.The whole sequences inbred line B73 were analyzed, 1,649 helitron-like transposons including 1,515 helAs and 134 helBs identified....
Members of the ADP-ribosylation factor family, which are GTP-binding proteins, involved in metabolite transport, cell division, and expansion. Although there has been a significant amount research on small their roles functions regulating maize kernel size remain elusive. Here, we identified ZmArf2 as factor-like family member that is highly conserved during evolution. Maize zmarf2 mutants showed characteristic smaller size. Conversely, overexpression increased Furthermore, heterologous...
Maize with high grain protein and oil contents offers great advantages for human food animal feed.In this study, of 282 263 F 7:8 recombinant inbred lines (RILs) 2 crosses were evaluated in 4 environments within between populations.The RILs developed from an high-oil maize line normal dent lines.A total 16 single-population QTLs 19 joint-population identified content, 21 detected protein-oil each the tested combination.Most content greatly influenced by variation among populations...
Triosephosphate isomerase (TPI) is an enzyme that functions in plant energy production, accumulation, and conversion. To understand its function maize, we characterized a maize TPI mutant, zmtpi4. In comparison to the wild type, zmtpi4 mutants showed altered ear development, reduced kernel weight starch content, modified granule morphology, amylose amylopectin content. Protein, ATP, pyruvate contents were reduced, indicating ZmTPI4 was involved glycolysis. Although subcellular localization...
Grain weight is one of the most important yield components and a developmentally complex structure comprised two major compartments (endosperm pericarp) in maize (Zea mays L.), however, very little known concerning coordinated accumulation numerous proteins involved. Herein, we used isobaric tags for relative absolute quantitation (iTRAQ)-based comparative proteomic method to analyze characteristics dynamic proteomics endosperm pericarp during grain development. Totally, 9539 were identified...
