Crop improvement for yield and drought tolerance is challenging due to the complex genetic nature of these traits and environmental dependencies. This study reports that transgenic over-expression of Zea mays AR GOS1 (ZAR1) enhanced maize organ growth, grain yield, and drought-stress tolerance. The ZAR1 transgene exhibited environmental interactions, with yield increase under Temperate Dry and ...

The viral genome-linked protein, VPg, of potyviruses is involved in viral genome replication and translation. To determine host proteins that interact with Sugarcane mosaic virus (SCMV) VPg, a yeast two-hybrid screen was used and a maize (Zea mays) Elongin C (ZmElc) protein was identified. ZmELC transcript was observed in all maize organs, but most highly in leaves and pistil extracts, and ZmEl...

More than 50% of agricultural land is threatened by water erosion in the Czech Republic. With respect to soil erosion, maize (Zea mays L.) belongs most problematic crops; one possibilities increase protection against intercropping. In this study, we attempted find out effects individual intercrops and their mixtures (sown 4–6 weeks after sowing maize) or a mixed culture (maize plus lupine) on l...

Active K(+) influx was studied in apical segments from maize (Zea mays L., hybrid lines XL 342) and pea (Pisum sativum L. var Laxton superbo) seedlings pretreated with the herbicide chlorsulfuron (2-chloro-N-[(4-methoxy-6-methyl-1,3,5-triazin-2-yl) aminocarbonyl]benzenesulfonamide).Even though both plants were sensitive to chlorsulfuron, a strong inhibition of K(+) uptake only was evident in ma...

introduction: the area under cultivation and yield of crops are affected by various factors, some of which are controllable and some others are uncontrollable. controllable factors are divided into two types of price and non-price factors. among the price factors, prices of agricultural products and inputs play an important role in expanding the cultivation area. uncontrollable factors also hav...

This research covered three villages in Kura local Government Area of Kano State. The study described the socio-economic characteristics of maize producers and their production techniques and also determined the profitability and resource use efficiency in the maize production. Structured questionnaires were used for primary data collection and 40 small scale producers were purposively selected...

Gene expression differences between divergent lineages caused by modification of cis regulatory elements are thought to be important in evolution. We assayed genome-wide cis and trans regulatory differences between maize and its wild progenitor, teosinte, using deep RNA sequencing in F1 hybrid and parent inbred lines for three tissue types (ear, leaf and stem). Pervasive regulatory variation wa...

Samples of haploid and hybrid seed from three different maize donor genotypes after maternal haploid induction were used to test the capability of automated near-infrared transmission spectroscopy to individually differentiate haploid from hybrid seeds. Using a two-step chemometric analysis in which the seeds were first classified according to genotype and then the haploid or hybrid status was...

This opinion reports on an evaluation of a risk assessment for placing on the market the genetically modified herbicide tolerant and insect resistant maize MON89034 x NK603 for food and feed uses, import and processing. Conventional breeding methods were used in the production of maize MON89034 x NK603 from inbred lines of the respective parental events. The structural integrity of the inserts ...

Bio-fertilizers are naturally occurring soil bacteria that aggressively colonize plant roots and benefit plants by providing growth promotion. This investigation was aimed at determining the effect of Nitroxin bio-fertilizer application on growth, inoculation and yield production of corn hybrids. An experiment was conducted as split plot on the basis of randomized complete block design with fou...
