Abstract:

The proportion of resources which an organism devotes to reproduction has been assumed to be of great evolutionary and ecological significance. However, in previous studies of reproductive allocation (RA) in plants, there has been no consensus of precisely what is being measured nor how it should be measured. An attempt was made to determine the 'best' method of measuring RA and then apply this to a range of species with differing ecological strategies. Under nutrient stress caused by a low N treatment Taraxacum officinale and Poa annua were found to maintain their RA despite up to 4 fold redu

Abstract:

Analysis of photomorphogenic mutants and transgenic plants provides further insights into the roles of individual phytochrome species. The presence of a significant early-flowering response to low R/FR ratio has been reveled in Arabidopsis phyB mutants, that are also homozygous for a late-flowering mutation. This firstly, implicates at least one other novel phytochrome species, in addition to phytochrome B, in the low R/FR ratio-mediated early- flowering response. Secondly, identifies features that are likely to represent a loss-of-function mutant in this novel phytochrome species. Examination

Flowering plants exhibit a particular pattern of seasonal cycle to suit the changing seasons for maximum survival and reproduction success. Temperature plays a key role in controlling flowering time of many plants. Fragaria vesca f. vesca is seasonal flowering and runnering. While it is not known to require vernalisation to flower, cool and cold temperatures affect its vegetative and reproductive development. An F. vesca VIN3-like (FvVIL) mRNA was isolated and characterised. It has a PHO finger domain, a FNIII domain and a VIO domain, which characterise the VIN3 family genes of Arabidopsis tha

The angiosperm order Malpighiales includes \(\sim 16,000\) species and constitutes up to 40% of the understory tree diversity in tropical rain forests. Despite remarkable progress in angiosperm phylogenetics during the last 20 years, relationships within Malpighiales have remained poorly resolved, possibly due to its rapid rise during the mid-Cretaceous. Using phylogenomic approaches, including analyses of 82 plastid genes from 58 species, we identified 12 new clades in Malpighiales and substantially increased resolution along the backbone (Chapter 1).

Abstract:

Flowering is controlled by a series of signals integrated to regulate gene expression and coordinate development. The flowering hormone FLOWERING LOCUS T (FT) positively regulates flowering while the highly homologous TERMINAL FLOWERING 1 (TFL1) negatively regulates flowering. FT is recruited to the promoter in a complex with FD, a transcription factor belonging to the bZIP family, and 14-3-3. This complex is called flowering activating complex (FAC). Here TFL1 is shown to form a complex with 14-3-3 proteins and FD that has striking similarity to the FAC. By probing the extended loop of TFL1 a

Thesis (MSc)--University of Stellenbosch, 2005.<br>ENGLISH ABSTRACT: The aim of this study was to elucidate the control of flowering in Protea spp. The main factor that makes studying flowering in this diverse genus so challenging is the fact that most Protea spp. and their commercial hybrids have very dissimilar flowering times. The carbon input into floral organ formation and support is expensive as flowers from Protea spp are arranged in a very large ‘flowerhead’ (50 mm by 130 mm for ‘Carnival’) that can take up to two months to develop fully. Therefore the carbon needed for structural

Abstract:

Environmental signals such as photoperiod and temperature provide plants with seasonal information, allowing them to time flowering to occur in favourable conditions. Most ecotypes of the model plant Arabidopsis thaliana flower earlier in long photoperiods and after prolonged exposure to cold (vernalization). The vernalized state is stable through mitosis, but is not transmitted to progeny, suggesting that the vernalization signal may be transmitted via a modification of DNA such as cytosine methylation. The role of methylation in the vernalization response is investigated in this thesis.

On average, achenes mature in 22 days and are dispersed 53 days after flowering.
