Expression of 3-hydroxy-3-methylglutaryl coenzyme a reductase in maize as influenced by light and bleaching herbicides
… is highly expressed in 4-day-old etiolated seedlings of normal ('DeKalb XL72AA'), dwarf (<u>d₅</u>), and albino (<u>lw₃</u>) maize (<u>Zea mays</u> L.). HMGR activity of maize seedlings appeared to be exclusively associated with the microsomal rather than the plastidic fraction of maize …

Studies With Triazoles to Alleviate Drought Stress in GreenHouse-Grown Maize (Zea mays) Seedlings
… often sporadic and unreliable, can expose young maize seedlings to severe drought. Through the use of plant growth regulators (PGR), maize seedlings can perhaps be altered to elicit responses that mimic drought adaptation mechanisms. A series of studies conducted in the laboratory and greenhouse …

Characterization of Maize Cytochrome P450s
Messenger RNAs encoded by other maize P450 clones (CYP71C1, CYP51, CYP73A7, CYP73A6, CYP92A1, CYP95A1, and the ESTs 6c06b11 and 7c02c12) were also characterized with regard to their induction response to naphthalic anhydride and triasulfuron treatment. In addition, maize seedlings were also …

Expression of maize genes on a specific chromosome in the presence of a foreign genome.
Oat-maize addition (OMA) lines are derived from oat x maize sexual hybrids in which individual maize chromosomes have been retained in embryo-rescued plants containing a full complement of oat chromosomes. The maize Affymetrix microarray was used to analyze transcripts from three independently …

Mixed infections of maize dwarf mosaic virus and cucumber mosaic virus in maize
Maize plants collected in three geographically distinct regions of South Africa were found to be doubly infected with maize dwarf mosaic (MDMV) and cucumber mosaic virus (CMV). A mixed infection of these two viruses could be maintained in maize plants grown under laboratory conditions. The …

Chemometric Analysis of Multivariate Liquid Chromatography Data: Applications in Pharmacokinetics, Metabolomics, and Toxicology
… liquid chromatography separations with DAD. Maize seedlings were analyzed, specifically focusing on indole-3-acetic acid (IAA) and related compounds. Window target testing factor analysis was used to identify the spectral groups represented by the standards in the mutant and wild-type …

6-deoxy-6-amino chitosan: A plant defence priming biopolymer that enhances resistance against Botrytis cinerea in tomato and Fusarium verticillioides in maize
… properties in the tomato/Botrytis cinerea and maize/ Fusarium verticillioides pathosystems. In the B. cinerea pathosystem, various concentrations of aminochitosan were assessed for their antifungal effectiveness against B. cinerea growth and sporulation. Additionally, in planta studies were …

An investigation of Fusarium verticillioides infection in maize using physiological and molecular approaches
Abstract Maize (Zea mays L.) is an important staple food crop in sub-Saharan Africa providing food security to millions of people. Fusarium verticillioides is an important fungal pathogen that infects maize and causes 'Fusarium Ear Rot' which decreases maize kernel yield and quality. In addition, …

MOLECULAR APPROACHES TO ANALYZE HORIZONTAL RESISTANCE AMONG PLANT SPECIES (MAIZE, SOYBEAN, AND ARABIDOPSIS) TO SYNTENIC FUSARIAL PATHOGENS (F. GRAMINEARUM AND F. VIRGULIFORME)
… resistance in different plant species (mainly in maize, soybean, and Arabidopsis); identify and clone disease resistance genes; decipher their quantitative responses to Fusarial pathogens and mycotoxin deoxynivalenol (DON); identified genes that were transcriptionally regulated when the plants …

Phenotypic and biochemical characterisation of the causal agent of bacterial leaf streak of maize
Maize is the staple food for a majority of people in Southern Africa, but plant diseases are responsible for at least 10% of crop production losses. Bacterial leaf streak (BLS) of maize was first reported in South Africa in 1949 and has not been reported elsewhere. Very little is known about the …

A new approach for delivery of entomopathogenic fungi for plant protection against insect pests and plant diseases via maize seed : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
… from the fungal isolates where then used to coat maize seed, to determine the effect of each fungal isolate –plant interaction on plant growth and resistance to insect and disease damage. In presence of the grass grub Costelytra giveni (Coleoptera: Scarabaeidae) and the maize disease fungus, …

CHARACTERIZATION OF PROTEOMIC CHANGES IN CROPS DURING METABOLIC ADAPTATION TO DIFFERENT NITROGEN INPUTS
… in Arabidopsis and in model crops, such as maize, rice and tomato. Nevertheless, analogies and peculiarities remain to be verified in other crop species. For instance, nitrogen nutrition has been only slightly investigated in perennial plants, and proteomics has been rarely applied in this …

Systems Evaluation of Shallow Anhydrous Ammonia Placements, Rates, and Timing on Maize Plant Uniformity, Yield and N Use Efficiency
… their fertilizer management practices during maize (<em>Zea mays</em> L.) production. With the advent of precision guidance systems, maize farmers in various tillage systems have more options in pre-plant nutrient banding relative to the intended crop rows or throughout the entire growing …
