Investigator(s):

Corlett RT

Department:

Source(s) of Funding:

Start Date:

07/2005

 

Abstract:

Seed dispersal by birds has a major influence on both plant persistence in forest fragments and forest recovery in deforested areas. A decade of research in Hong Kong has identified the major seed dispersal agents, but attempts to measure the spatial and temporal variation in fruit removal rates have been confounded by spatial and temporal variation in fruit characteristics and abundance. The aim of this project is to design a standard "artificial fruit" that can be used to compare frugivory rates between sites, microhabitats and seasons. Each fruit design will be tested with captive birds and under close observation in the field to assess if frugivore responses are similar to - or, at least, correlated with - their responses to natural wild fruits.

Abstract:

Molecular systematics of fungi, particularly of the Ascomycota, relies heavily on the use of nuclear ribonsomal DNA. Use of these genes does not resolve all relationships with this phylum. This study aims to address these problems by elucidating the modes and rates of molecular evolution for 10 genes in taxa of the Sordariomycetes. Results can provide valuable information for the selection of alternatives to nuclear ribosomal DNA and lead to a more thorough understanding of evolutionary processes in the Ascomycota, and fungi in general.

Abstract:

Guignardia/Phyllosticta are specious genera including plant pathogenic fungi whose classification is primarily based on few morphological characters. Insufficient morphologies, physiological specialization, cultural variation and overlapping host ranges cause problems to plant pathologist in species identification. Previous rDNA sequence data have been inadequate to resolve species and generic relationships. To date, their taxonomy, especially species that occur as economically important plant pathogens, remains equivocal and poorly understood. This study will examine type species of these fungi and will eventually result in a world monograph. Fresh material of important pathogens and generic types will be obtained and where necessary epitypes with living ex-types designated. We will also re-evaluate phylogenetic relationships of these fungi aimed at redefining the morphological concepts using a morphological and molecular approach, the latter based on several genes (Beta Tubulin, Histone, Mitochondrial encoded genes, translation elongation factor). A small number of taxa will be studied in the initial research, however, a larger number of taxa possessing diverse morphologies will eventually be studied. Sequencing and cladistic analyses of several genes for deriving independent hypotheses of character homology, evolutionary rate of these genes and their impact on phylogenetic estimation will be considered. From a pathological point of view, the identification of DNA sequences that are highly specific to a plant pathogen will aid in the development of PCR-based diagnostic tools that are more sensitive and specific than the classical methods used to identify a pathogen. For instance, the translation elongation factor has successfully been used to classify species of Fusarium and is economically extremely important. Such developments will permit further improvement of crops and crop management practices. Objectives: 1. To re-examine all Guignardia/Phyllosticta species and where necessary designate a living epitype for important pathogens and generic types (the initial studies will deal with about 40 species). 2. To investigate the evolutionary relationships of Guignardia/Phyllosticta based on a multigene phylogenetic approach. 3. To assess the mode of evolution of several genes and the phylogenetic significance of specific morphological characters at generic, species and below species level. 4. To locate a specific gene sequence that can be used to distinguish between species in the genus. Introduction Guignardia (Viala and Ravaz, 1892) is a loculascomycetous genus and along with its anamorph Phyllosticta are widespread and important plant pathogens. The placement of Guignardia at the familial level is unresolved and the genus was placed in the Botryosphaeriaceae (Dothideales) by Kirk et al. (2001) and Mycosphaerellaceae, (Mycosphaerellales) by Eriksson (2005). Species of Guignardia have been recorded as endophytes, plant pathogens and saprobes (Raabe et al., 1981; Baayen et al., 2002; Glienke-Blanco et al., 2002). It may be that they are usually endophytes (asymptomatic inhabitants of living plants) but switch their lifestyle to pathogens when the plant becomes stressed or saprobes when the plant senesces. Furthermore, although Guignardia and Phyllosticta species are repeatedly isolated as endophytes from plants, it is not clear whether they comprise one or several taxa. The most notable work on Guignardia/Phyllosticta species have been carried out on pathogens. Guignardia baccae causes false black rot of grapevine, while G. citricarpa causes black spot of leaves and fruit of Citrus species and G. aesculi causes brown leaf mold of Horse Chestnut. The anamorph is also an equally important pathogenic genus: Phyllosticta ampelicida causes leaf spot of Ivy; Phyllosticta capitalensis causes leaf spots of orchid leaves; Phyllosticta sojicola causes leaf spot on soybean; and Phyllosticta vaccinii causes early rot of cranberry fruit. Both P. passifloramaculans and P. superficialis have been reported on Passiflora edulis in Brazil (Batista & Vital 1952, Mendes et al. 1998), but none of the three species reported on Passiflora spp. were accepted in the most recent revision of the genus (van der Aa & Vanev 2002). Species numbers in both genera are also problematic. The probable number of species in Guignardia is 40 species (Kirk et al., 2001), however more than 313 species epithets can be found in Index Fungorum (2005) of which 35 have been transferred to other genera. Similarly Phyllosticta probably has 46 species but there are 2885 epithets in the Index Fungorum. There is considerable taxonomic confusion in Guignardia and its anamorph Phyllosticta and because of their important as plant pathogens this confusion should be resolved. This study therefore aims to clarify the phylogenetic relationships and to contribute to the understanding of Guignardia and Phyllosticta species. In this study, the potential genomic sources of beta tubulin, histone, translation elongation factor and mitochondrial encoded genes (e.g. cytochrome B and mtSSU) will be explored. These genes provide sufficient genetic characters and are characterized by domains that evolve at appropriate rate that would be indispensable as genetic markers within and among closely related pathogenic species. We present a different perspective on the systematics of these asexual fungi by taking into account morphology, and by investigating the molecular evolution of these genes and their effects on phylogeny reconstruction. Problems pointed out by previous researchers in this field will be considered and our experiment will be moderated by careful choice of appropriate characters for use at different levels, adequate taxon sampling, and application of proper methods of analysis. With emphasis on molecular phylogenetic evidence from genes sharing different functions and origins, results will permit a more accurate re-evaluation of the phylogenetic significance of morphological characters; assess the modes and rates of evolution of molecular evolution of these genes; and help establish some anamorph-teleomorph connections as well as hypotheses of character evolution. This first part of the study will provide publishable results in high impact factor journals. A major long term component this study will be to re-examine all type material of species in Guignardia/Phyllosticta. The study will involve locating and borrowing material from international herbaria and making careful examination in the laboratory. This approach will allow a redefinition of species and generic concepts based on morphological examination and molecular analysis. In the case of important pathogens and generic types living material will be recollected from the type location and the same host. This living material will be isolated and cultures used from molecular work. Material will be designated an epitype where necessary and ex-types deposited in international culture collections as representative living species for future study. The eventaul outcome of this study will be a monograph of Guignardia/Phyllosticta.

Abstract:

To determine fluctuating asymmetry (FA) of T. japonica based on the morphological characteristics of their scutum and tergum, with an estimation of measurement errors; to compare the level of FA of T. japonica collected from three different shore levels (low, mid and high) of two polluted sites and two clean sites; to test the relationship between the level of pollutants (e.g. heavy metals) and the degree of FA in T. japonica. The present results will enable us to identify the key factor(s), which affect the FA in T. japonica and answer whether or not FA can be used as a reliable pollution indicator.

Abstract:

Research BackgroundMetallothioneins (MTs) are a group of low molecular weight, soluble, cysteine-rich and heat-stable proteins, which are induced by and bind a variety of trace metals such as Ag, Cd, Cu, Hg and Zn (Roesijadi 1992; Dallinger et al. 1997). They have important and unique roles in homeostasis of essential metals (e.g. Zn and Cu) and detoxification of toxic metals (e.g. Cd and Hg). Correspondingly, they have been proposed as potential biomarkers for metal contamination in the aquatic environment. Recently, the Working Group on Biological Effects of Contaminants (WGBEC) of the International Council for the Exploration of the Sea (ICES) has recommended MT as one of the priority biomarkers (in fish and bivalve molluscs) for biomonitoring programmes at national or international level (ICES, 2003). Over the last five years, the PI has demonstrated that the concentration of total MTs is a good predictor of bioavailable fractions of Cu and Cd in the marine gastropods Littorina littorea and Nucella lapillus (Leung & Furness 1999a,b; Leung et al. 2001, in press), and the MT level in the molluscs is only moderately influenced by physical factors (e.g. salinity and temperature; Leung et al. 2000, Leung & Furness 2001a) and biotic factors (e.g. growth; Leung et al. 2001), making MTs as prospective biomarkers for metal contamination. Nevertheless, previous studies have showed that MTs and MT-like proteins (MTLPs) in common biomonitor species, such as bivalve and gastropod molluscs, can also be induced by exposure to other non-metal stressors such as oxidative or xenobiotic substances (Viarengo et al. 1999; Leung & Furness, 2001b). For instance, the freshwater fish, Carassius cuvieri exposed to violent air-pumping stress for 6 days exhibited time-dependent induction of two different isoforms of MTs (i.e. ccMT-1 and ccMT-2) in their livers and kidneys that might be associated with the release of endogenous factors, such as glucocorticoids (Muto et al. 1999). To date, however, characteristics and functions of MTs or MTLPs induced by non-metal stressors in molluscs are still poorly understood. Study ObjectivesThis study is, therefore, designed to investigate, for the first time, the characteristics and function of various MT-isoforms in the common biomonitors, Perna viridis (green lipped mussels) and Thais clavigera (rock shells) which are induced by exposure to non-metal stressors including oxidative substances (e.g. exposure to hydrogen peroxide) and xenobiotics (e.g. organotin compounds). These MT-isoforms will be characterised using advance proteomic techniques and compared to those induced by MT-inducing metals such as Cd, Cu and Zn. To test whether or not these non-metal induced MT-isoforms play significantly protective functions, i.e., serving as antioxidants, cellular biomarkers such as RNA/RNA ratio and activities of antioxidant enzymes will also be examined in these model organisms.Cited ReferencesDallinger R, Berger B, Hunziker P, Kägi JHR (1997).

Abstract:

The oxidative damages caused by reactive oxygen species, such as superoxide radical, hydroxyl radicals and peroxyl radicals, on lipids, proteins and nucleic acids may trigger various chronic diseases such as coronary heart diseases, atherosclerosis, cancer and aging (Willett, 1991; Finkel & Holbrook, 2000). The health promoting effect of antioxidants from plants is thought to arise from their protective effects by counteracting reactive oxygen species. Epidemiological studies have demonstrated an inverse association between intake of antioxidants and mortality from age-related diseases such as coronary heart diseases and cancer (Gey, 1990; La Vecchia, 2001). Chinese medicinal herbs have been used to treat human diseases in China for centuries. People are becoming increasingly interested in Chinese medicinal herbs because of their low toxicity and good therapeutic performance. In recent years, studies on antioxidant activity of Chinese medicinal herbs have increased remarkably due to increased interest in their potential of being used as a rich and natural source for extracting antioxidant compounds (Liu & Ng, 2000; Ou et al, 2003; Cai, 2004; Tang et al, 2004). Chinese medicinal herbs contained a wide variety of natural antioxidants such as phenolic acids, flavonoids and tannins, which possess diverse biological activities such as promoting blood circulation, elevating immune function, anticancer and anti-aging (Cai, 1999; Shen, 2000). These activities may be related to their antioxidant activity (Chung et al, 1998; Yim & Ko, 2002). Our recent study showed that the stem of Polygonum multiflorum Thunb (Ye Jiao Teng) possessed very strong antioxidant activity, an even more potent antioxidant capacity (approximate 2 times) than its root (He Sou Wu), which is a famous Chinese medicinal herb that has been used as a tonic and an anti-aging agent (Wong, 2006). This result has been proved further by three different extract methods (boiling water, 80% methanol, and 50% ethanol) and three antioxidant evaluation methods (ferric reducing antioxidant power assay, Trolox equivalent antioxidant capacity assay, and Folin-Ciocalteu method) in our laboratory recently. With the assumption that antioxidant activity is the chief activity responsible for the health benefits of the root of P. multiflorum Thunb, the stem of this medicinal plant is therefore likely to possess greater health benefits than the root. Furthermore, the stem of P. multiflorum Thunb is available at a low cost and thus provides an economic source of natural antioxidants. However, no report on the antioxidant components of the stem of P. multiflorum Thunb could be found in the literature. Therefore, isolation and characterization of its individual antioxidant components is very interesting and important. The objectives of the proposed research are: (1) to find out antioxidant components in the stem of P. multiflorum Thunb; (2) to identify molecule structures of the compounds with antioxidant activity; (3) to establish a high-speed counter-current chromatographic method for the preparation of pure antioxidants from the crude extract of the stem of P. multiflorum Thunb. In order to achieve the objective, several issues need to be addressed: (1) How to isolate and purify antioxidant components in the herb? (2) How to identify molecule structures of the compounds with antioxidant activity? (3) How to prepare pure antioxidants from the crude extract of this herb? Findings from the proposed study will provide scientific basis for the better and wider use of this herb. It is hoped also that new antioxidant compounds might be found from the proposed study.

Project Title:

Heat shock protein expression profiles in marine intertidal organisms in response to heat stress

Investigator(s):

Williams GA, Leung KMY

Department:

Ecology & Biodiversity

Source(s) of Funding:

Small Project Funding

Start Date:

11/2003

 

Abstract:

To optimize heat shock protein detection and quantification in different tissues of intertidal marine invertebrates (barnacles, mussels and limpets); to establish the in situ profile of heat shock protein (hsp) expression with relation to time and temperature; to explore the relevance of chaperone molecules in biogeographical distribution and habitat partitioning of intertidal organisms; to determine the cellular heat shock response of intertidal organisms under controlled laboratory experiments and the relevance of acclimatization in thermotolerance threshold; to test the hypothesis that organisms found at different tidal levels will exhibit different hsp expression profiles; to test the hypothesis that laboratory acclimatization will alter the thermotolerance threshold and hsp expression profiles of organisms.
