(University of Pretoria, 2005-05-20)Please read the summary in the section 02back (Appendix 1) of this document
-
(University of Pretoria, 2005-05-19)Please read the abstract in the section 00front of this document
-
(University of Pretoria, 2014)Cowpea production is severely affected by environmental stress factors, particularly drought. More drought-tolerant crops are therefore urgently required for future improvement of food production in Mozambique. To increase ...
-
(University of Pretoria, 2013)Activity and transcription profiles of two classes of cysteine proteases, papain- and legumain-like cysteine proteases, as well as their potential inhibitors, cysteine protease inhibitors (cystatins), were investigated in ...
-
(University of Pretoria, 2010-11-23)A symbiotic association between leguminous roots and soil fixing nitrogen bacteria is required for legume nodule formation. The primary function of nodules is the fixation of nitrogen from the atmosphere into an accessible ...
-
(University of Pretoria, 2010-10-24)Sorghum (Sorghum bicolor L. Moench) ranks fifth worldwide in production among cereals. It is a major staple food for millions in Africa and Asia, and a major livestock feed grain in developed countries. However, the sorghum ...
-
(University of Pretoria, 2016)Banana Xanthomonas wilt (BXW) remains a major problem to banana production in the East and Central African region. This PhD study evaluated the expression of stacked Hrap (hypersensitive response assisting protein) and ...
-
(University of Pretoria, 2008-11-11)Bacillus thuringiensis (Bt) is a gram-positive common soil bacterium that produces crystals (Cry) containing proteins that are toxic to certain insects, in particular larvae of Lepidoptera and Diptera. The Bt toxin in the ...
-
(University of Pretoria, 2012-11-21)The suitability of a plant-based transient expression system using the agro-infiltration technique was compared to an Escherichia coli (E. coli)-based expression system to produce the VP1 protein from Serotype O, South ...
-
(University of Pretoria, 2012-06-07)Early maturity is one of the most important aerial growth traits next to bunch size, in determining banana productivity. However, low seed fertility in banana and the lack of breeding lines limit the application of ...
-
(University of Pretoria, 2011-10-24)The Non-expressor of pathogenesis-related1 gene (NPR1) mediates the induction of pathogenesis-related (PR) gene products, vital for resistance in plants. In this study, the role of two previously isolated Cavendish banana ...
-
(University of Pretoria, 2006-12-05)Plant cysteine proteinase inhibitors or also called phytocystatins inhibit the action of cysteine proteinases in plants. These proteinases are involved in many developmental processes by degrading proteins. In this study ...
-
(University of Pretoria, 2006)Bananas and plantains (Musa spp.) are cultivated commercially as a dessert fruit and by small-scale farmers as a staple food crop in many countries of the world. Sustainable production, however, is threatened by a number ...
-
(University of Pretoria, 2009-10-29)For centuries people have used plants as medicine or food additives with varying success to cure and prevent diseases. Written records about medicinal plants date back at least 5 000 years to the Sumerians. According to ...

(University of Pretoria, 2003)Please read the abstract in the section 00front of this document
-
(University of Pretoria, 2011-09-22)Novel conserved amino acid variations of papaya cystatin (PC) were investigated by amino acid substitutions using oryzacystatin-I (OCI) as a model plant cystatin for comparison. These amino acid residues in the conserved ...
-
(University of Pretoria, 2012)Drought causes considerable reduction of legume productivity and significantly threatens the food security, and this situation is expected to be aggravated due to climate change. In soybean and common bean, water resource ...

(University of Pretoria, 2005-01-17)Please read the abstract in the section 00front of this document
-
(University of Pretoria, 2009-04-16)The protein encoded by the Nonexpressor of pathogenesis-related gene 1 (NPR1) also referred to as Non inducible immunitiy 1 (NIM1) or Salicylic acid insensitive 1 (SAI1) is a co-transcriptional regulator. The NPR1 gene ...
-
(University of Pretoria, 2012-09-14)Lodging is a key agronomic problem in E. tef. due to morpho-physiological features, such tall and slender phenotype of the plant. Gibberellins metabolic genes are key targets in the control of plant height. Plant growth ...
