The cob operon encodes functions needed for the biosynthesis of adenosylcobalamin (Ado-B12). Propanediol induces transcription of the cob operon and the neighboring pdu operon, which encodes proteins for the B12-dependent degradation of propanediol. Expression of the cob (but not the pdu) operon is repressed by exogenous cyanocobalamin. Evidence is provided that cob operon repression is signale...

To control organ shape, plant cells expand differentially. The organization of the cellulose microfibrils in the cell wall is a key determinant of differential expansion. Mutations in the COBRA (COB) gene of Arabidopsis, known to affect the orientation of cell expansion in the root, are reported here to reduce the amount of crystalline cellulose in cell walls in the root growth zone. The COB ge...

The field experiment was carried out during Rabi season of 2022 at the Crop Research Farm, Department Agronomy, Naini Agricultural Institute, Sam Higginbottom University Agriculture, Technology And Sciences, Prayagraj (U.P.) India, to study effect bio- fertilizers and zinc sulphate on growth yield Maize. treatments consist Bio-fertilizers PSB, Azotobacter, PSB + Azotobacter ZnSO4 (20, 25, 30 kg...

The present investigation was carried out to assess genetic variability parameters, correlation coefficient analysis, path analysis in 21 maize genotypes for 15 quantitative traits viz Days 50% tasseling, silking, anthesis – silking interval, 75% maturity, Plant height (cm), Ear Cob length girth weight (g), Number of grain rows per cob, grains row, 100 Biological yield plant Harvest index (%), ...

An experiment was conducted including 20 genotypes of maize during Kharif season 2020-21. All characters under study showed highly significant variation. High values genotypic and phenotypic coefficients variation were observed for the like anthesis silking interval, grain yield per plant, biological yield, number grains row, rows cob, harvest index ear height. Biological plant height, height h...

Tools that provide improved ability to relate genotype to phenotype have the potential to accelerate breeding for desired traits and to improve our understanding of the molecular variants that underlie phenotypes. The availability of large-scale gene expression profiles in maize provides an opportunity to advance our understanding of complex traits in this agronomically important species. We bu...
