Abstract:

Forty-four actin genes from five angiosperm species, whose evolutionary relationships are well characterized, were PCR-cloned and sequenced. Phylogenetic analysis of 34 of these actin genes, along with those previously published, indicate that plant actin genes are monophyletic and underwent a rapid radiation early in land plant evolution. Six sets of putative orthologues have been identified and their sequences were used to calculate rates of evolution. The synonomous rate of substitution $(5.44\times10\sp{-9}$/site/year) is similar to that of other nuclear protein-encoding genes but the non-

Abstract:

Late Cretaceous angiosperm leaf floras from the Antarctic Peninsula have been studied and described for the first time. The Hidden Lake Formation (Coniacian) and Santa Marta Formation (Santonian-early Campanian) floras were preserved within shallow marine strata exposed on James Ross Island. This area was located at approximately 65°S during the Late Cretaceous. These fossils represent the remains of vegetation growing in the southern high latitudes on an emergent volcanic arc. The plants probably grew on the delta top and along the edge of streams. The leaf fossils are preserved as isolated a

Abstract:

Genome size (GS) is a fundamental trait influencing cellular, developmental and ecological parameters, and varies c. 2400- fold in angiosperms. This astonishing range has the potential to influence a plant's nutrient demands, since nucleic acids are amongst the most phosphate and nitrogen demanding cellular biomolecules, and hence its ability to grow and compete in environments where macronutrients are limited. Angiosperm GS are strongly skewed towards small genomes, despite the prevalence of polyploidy in the ancestry of most if not all angiosperm lineages. This thesis examines the hypothesis

Abstract:

BACKGROUND:Most studies inferring species phylogenies use sequences from single copy genes or sets of orthologs culled from gene families. For taxa such as plants, with very high levels of gene duplication in their nuclear genomes, this has limited the exploitation of nuclear sequences for phylogenetic studies, such as those available in large EST libraries. One rarely used method of inference, gene tree parsimony, can infer species trees from gene families undergoing duplication and loss, but its performance has not been evaluated at a phylogenomic scale for EST data in plants.RESULTS:A gene

Strelitziaceae is a tropical monocot family comprising three genera and seven species: Ravenala Adans and Phenkospermum Endl., which are monotypic, and five species of Strelitzia Aiton.

Unlike most plant pigments, which degrade after cell death, aril pigments in the family persist for decades. Chemical properties of the compounds are unusual, and do not match those of known pigment classes (caroteno

Abstract:

Avocado is an economically important crop with ~ 60-70 % oil, by dry weight, in its fruit mesocarp tissue. The steady increase in global demand for avocado (9% per year) has driven interest to identify the biochemical and molecular factors that regulate its triacylglycerol (TAG, oil) biosynthesis. Using 454- and Illumina-based RNA-Seq approaches, we examined the transcriptional basis for TAG biosynthesis in developing mesocarp of avocado, in relation to other seed and non-seed tissues. Deep transcriptional profiling data allowed us to identify several transcripts that were differentially repre

The mechanism by which plants synthesize and store high amounts of triacylglycerols (TAG) in tissues other than seeds is not well understood.

Persea americana (avocado), a basal angiosperm with unique features that are ancestral to most flowering plants, stores ~ 70 % TAG per dry weight in its mesocarp, a nonseed tissue.

Ecologists and evolutionary biologists have long recognized that species diversity is unequally distributed among angiosperm lineages.

Species within Valerianaceae, found in the South American Andes, appear to be an example of such a rapid radiation. Although much attention has been paid to the phylogeny of the South American species of Valerianaceae, there is still a great deal of uncertainty regarding species rela

A plant’s genetic toolkit governs its selection of beneficial symbionts and the developmental extent of these intimate interactions.

Abstract:

Angiosperm seed development requires co-ordinated development of the embryo and a second zygotic tissue, the endosperm. In Arabidopsis thaliana, the endosperm is ephemeral and is largely consumed by the embryo during seed development. In addition to a role in embryo nutrition, it is also likely that the endosperm may play a more direct role in signalling to the embryo to regulate development. Despite their importance for embryo development, these processes are very poorly understood. The ZHOUPI (ZOU) gene provides an important tool to address these problems.
