Abstract:

The genus, Leucadendron, of the Cape Proteaceae family, is made up of over 70 dioecious species that vary in their degree of sexual dimorphism. Males are generally more highly ramified (branched) with smaller leaves compared to corresponding females. It has been hypothesised that sexual dimorphism in Leucadendrons is linked to serotiny (a fire-adapted reproductive strategy), where highly serotinous females may incur extra resource costs in order to keep their transpiring cones alive between fires. This hypothesis predicts that the female morphology might be associated with more efficient resou

A morphometric analysis of herbarium specimens identified qualitative and quantitative characters unambiguously diagnostic for S. lancifolia. These included the presence of glands on the phyllaries; long, wide-diameter rhizomes; thick stems; and a long pappus on disk fl

Abstract:

Nature creates high performance materials under modest conditions, i.e., neutral pH and ambient temperature and pressure. One of the most significant materials is the plant cell wall. The plant cell wall is a composite of oriented cellulose microfibrils reinforcing a lignin/hemicellulose matrix. In principle, the plant cell wall composite is designed much like a synthetic fiber-reinforced polymer composite. Unlike synthetic composites, the plant cell wall has an excellent combination of high modulus, strength, toughness and low density that originates in the optimal interactions between th

Abstract:

Mitosis and meiosis of five Plantago species were analyzed. Plantago argyrea, P. patagonica and P. wrightiana contain 2n = 20 chromosomes and P. rhodosperma and P. virginica 2n = 24 chromosomes. Similar modes of evolution of the karyotypes of the 2n = 20 species are suggested. All species are presumed to be tetraploid, arising from 2n = 10 and 2n = 12 ancestors. Structural changes in the karyotype of 2n = 12 species could produce one or more large chromosomes resulting in a decrease in chromosomes from 6 to 5. Consequently, chromosome lengths in 2n = 10 and derived 2n = 20 species could be inc

Abstract:

Morphological and growth observations made on landraces of African yam bean (AYB) used in this study confirm that this species is the most morphologically variable in the genus (Potter, 1992). Morphological characters such as seed colour, stem colour, internode length, leaf size and number of leaves per plant were found to vary between landraces. Growth and development was controlled by both genotype and environment. Flowering was observed only when plants were grown at 25°C, rather than at 30°C, with a 12 h photoperiod. Tuber formation occurred only in AYBS and not in other landraces. Growth

Abstract:

Bambara groundnut (Vigna subterranea (L.) Verdc.) is an important underutilised legume crop, grown mainly by female subsistence farmers in Africa under traditional low input agricultural systems. Bambara groundnut is known as being of high nutritional value, as an atmospheric nitrogen fixer and to possess high levels of drought, pest and disease tolerance. Bambara groundnut is a predominantly self-pollinated crop and is grown as locally adapted landraces. These are expected to exist as non-identical inbred lines and are generally low yielding.

Ballistosporic and statismosporic basidiosporogenesis however, has not been critically compared.

The fine structure of the basidiospores of Pluteus cervinus and Agrocybe acericola is described using TEM, SEM, and light microscopy.The basidiospore wall of Pluteus cervinus is bipartite.

Spores are uninucleated with the nucleus closely appressed to the cell membrane, located at the base of the spore near the hilar appendage. Mitochondria with few, well-delineated plate-like cristae are present. E

As a plant operating the C3 photosynthetic pathway and commonly grown under tropical conditions of high light intensity and temperature, rice (Oryza sativa) displays high levels of photorespiration, to the detriment of photosynthetic efficiency.

Abstract:

Cornichon (CNI) proteins are a conserved family of proteins among eukaryotes, from Erv14 in the yeast Saccharomyces cerevisiae to CNI homologs (CNIHs) in mammals and plants. Erv14 functions as a cargo receptor of coat protein complex II (COPII) for protein trafficking from the endoplasmic reticulum (ER) to the Golgi apparatus, en route to their final destinations. By interacting with specific cargo proteins, CNI proteins regulate key steps of embryo polarity in Drosophila, budding in yeast, and synaptic transmission in the mammalian brain.

Palms provide valuable commercial resources in the tropics and are dominant species in tropical lowland forests. While general biology of palms is well studied, there are gaps in the literature on palm growth through life stages and in response to environmental conditions. Literature gaps on palm growth could be caused by the slow growth of palms; it is difficult to monitor morphology and architecture for the periods of time necessary to capture changes.

Abstract:

The characteristic curd phenotype of the Brassica cauliflower consists of proliferating, arrested inflorescence and floral meristems. Recent analysis of the similar phenotype in the ap1-1/cal-1 mutant of the related crucifer Arabidopsis thaliana has led to speculation that the orthologous genes from Brassica oleracea L. may be responsible for this characteristic trait. Application of molecular genetic analysis to this hypothesis allows the presentation of a genetic model based on specific, mapped loci of BoCAL and BoAP 1.

Abstract:

Thesis (MTech (Agriculture))--Cape Peninsula University of Technology, 2017.<br>Cowpea (Vigna unguiculata (L.) Walp) is an important grain and fodder legume grown around the world. It is a dual purpose grain legume crop, providing food for man and livestock. Cowpea is identified as a potential crop to diversify food production, minimize production input by improving soil fertility and improve micronutrients of seed, therefore, improving human nutrition. There is limited information available on cowpea production and suitable agronomic practices including planting date to best suit different en

Abstract:

Carnivorous plants perform as both producers and consumers. Botanical carnivory has evolved in sunny, moist, nutrient-poor environments, and the primary nutrient supplied by prey is proposed to be nitrogen. There is a trade-off between carnivorous and photosynthetic structures which corresponds to degree of carnivory expression and available nutrients. This study was conducted on the hooded pitcher plant, Sarracenia minor, which is a facultative wetland plant and Florida-threatened species. Sarracenia minor is considered a specialist myrmecophage and ants characterize the majority of attracted

Mestrado em Engenharia Florestal e dos Recursos Naturais - Instituto Superior de Agronomia<br>A rizosfera é uma zona importante em termos de actividade e diversidade microbiana, onde ocorrem associações benéficas entre plantas e microorganismos, e é fundamental na produção agrícola. Ao proliferarem num meio complexo e heterogéneo como o solo, as raízes desenvolvem-se de forma estruturada, mas flexível, por forma a optimizar suas funções. Factores endógenos, como fisiologia e genética da planta, bem como factores exógenos abióticos e bióticos são elementos determinantes. Neste estudo propo

Abstract:

The development of wheat cultivars with unique quality traits is of major importance to the Australian wheat grower. Varietal diversity and flour quality of wheat are determined by genes and their products - proteins. Therefore, characterisation of the grain proteins will lead to discovery of potential protein markers for varietal identification and desirable quality attributes such as hardness, dough strength and extensibility. In order to screen the identified protein markers among thousands of breeder’s lines, specific high throughput detection methods are needed. In this study, a proteomi
