Abstract:
Ganoderma root disease in the community forest of sengon is one of the limiting factor to increase the productivity of sengonwood. This disease has been reported in West Java, East Java, South Sumatra and South Kalimantan. The survey was conducted to determine the existence of Ganoderma root disease in three sengon fields in Sleman, Yogyakarta. The existence of Ganoderma root disease was recognized based on the symptoms of diseased plants and the present of Ganoderma basidiocarp on the diseased sengon stem. The survey results on three sengon fields was succeed in finding diseased plants and also the basidiocarp of Ganoderma on the basal of the diseased plant stem. Symptoms that have been found was either dead or dying trees (few leaves left). The basidiocarp of Ganoderma on the diseased plants varies in characteristic while its young and mature. The basidiospores is ellipsoid, truncate, rough (coarsely echinulated), and double-walled. The Ganoderma colony was white and turned to yellow orange from the center. Based on this study the Ganoderma root disease in sengon plants has developed in Sleman, Yogyakarta. The presence of dead or dying trees with few leaves left between healthy sengon trees and the presence of Ganoderma basidiocarp in diseased trees are indicator of the presence of root disease in the sengon field caused by Ganoderma.

Abstract:
Ganoderma is a cosmopolitan genus of mushrooms, which can cause root and butt rot diseases on many tree species. Members of this genus are particularly diverse in tropical regions. Some Ganoderma spp. are medicinally active and therefore are used to treat human diseases or as a dietary supplement. In this study, three Ganoderma strains were collected in tropical southern Thailand. Phylogenetic analyses of combined ITS, LSU, TEF1α and RPB2 sequence data indicated that the three strains grouped in a distinct lineage within laccate Ganoderma. One strain was collected from Surat Thani Province clustered in the G. casuarinicola clade with high statistical support (MLBS = 100% / MPBS = 98% / PP = 0.96), while the other two strains of Ganoderma, collected from Nakhon Si Thammarat Province, formed a distinct well-supported clade (MLBS = 100% / MPBS = 100% / PP = 1.00) and are described here as a new species. Ganoderma casuarinicola is reported here as a new record to Thailand. Morphological differences of the two taxa and their closely related taxa are discussed. Colour photographs of macro and micro morphological characteristics and a phylogenetic tree to show the placement of the new record and new species are provided.

Abstract:
Herbal plants can be used to treat and prevent life-threatening diseases, such as prostate cancer, infections and other diseases. The findings from traditional medicine and the use of medicinal plants can help control and treat most problems due to prostate diseases. The aim of this study was to identify and report the most important medicinal plants that affect prostate disorders. Based on the results of the review of numerous articles indexed in the databases ISI, Scopus, PubMed, Google Scholar, etc., a number of plants have been reported to be used in the treatment and prevention of diseases, inflammation, infection, and cancer of the prostate gland. The plants include Panax ginseng, Arum palaestinum, Melissa officinalis, Syzygium paniculatum, Coptis chinensis, Embelia ribes, Scutellaria baicalensis, Tripterygium wilfordii, Salvia triloba, Ocimum tenuiflorum, Psidium guajava, Ganoderma lucidum, Litchi chinensis, Saussurea costus, Andrographis paniculata, Magnolia officinalis and Prunus africana. Phytochemical investigations have examined the therapeutic effects of medicinal plants effective on prostate cancer and their possible mechanisms of action and clinical effects as well as the use of active flavonoids in production of herbal drugs. Due to the active ingredients and important flavonoids of these plants, they can be used in production of herbal drugs that prevent and treat infections, inflammation and cancer of the prostate gland, and reduce the metastasis of prostate cancer cells, reducing the patients’ suffering and pain.

Abstract:
Molecular and immunological methods were applied for detecting the <i>Ganoderma</i> disease of coconut. Polyclonal antibodies (PAbs) raised against basidiocarp protein of <i>Ganoderma</i> were used. For the polymerase chain reaction (PCR) tests, the primer generated from the internal transcribed spacer region one (ITS 1) of ribosomal DNA gene of <i>Ganoderma</i>, which produced a PCR product of 167 bp in size, was used. Apparently healthy palms in two coconut gardens were tested for <i>Ganoderma</i> disease by ELISA test using basidiocarp protein antiserum. Field trials were laid out in these early-diagnosed palms for the management of the disease. Based on the ELISA results, <i>Pseudomonas fluorescens</i> + <i>Trichoderma viride</i> with chitin amended treatments arrested the multiplication of the pathogen and within 6 months showed an optical density (OD) below the level of infected plants. Integrated Disease Management (IDM) and fungicide tridemorph treated palms showed OD values below infection level within 7 months, and <i>T. harzianum</i> and <i>P. fluorescens</i> + <i>T. viride</i> treated palms showed OD values below infection level in 8 months.

Abstract:
One of the diseases that attack oil palm plants is stem rot disease. Control efforts that can be done is to use rhizosphere fungi from oil palm plants in peat soils. This study aimed to select fungi from rhizosphere of oil palm plants in peat soil based on morphological characteristics and test their potential as biological agents against Ganoderma boninense. This research was conducted by exploration, observation and experiment by using complete randomized design (RAL). The parameters observed were macroscopic characteristics of fungi from oil palm rhizosphere, disease severity index, fungus inhibition power from oil palm rhizosphere to G. boninense, colony diameter and growth rate of high antagonist rhizosphere fungus, hyperparasitic type of fungus from rhizosphere of oil palm plant with G. boninense and the morphological characteristics of fungi from high antagonist rhizosphere in macroscopic and microscopic. The results showed that 12 rhizosphere fungi isolates and 4 isolates were antagonist to G. boninense. Isolate J5 has a high antagonist power of 70.26% and is a genus Trichoderma, isolate J7 belongs to the genus Trichoderma, isolate J10 genus Aspergillus and isolate J12 genus Mucor.

Abstract:
Ganoderma lucidum is a medicinal mushroom widely used in Eastern countries and currently in global scale. Its fruiting body and mycelium are composed by polysaccharides, triterpenes and more than 200 secondary metabolites. These compounds exhibit a range of bioactivities, such as anti-inflammatory, antitumorigenic, antibacterial and antifungal action. Several scientific publications have demonstrated the potential and performance of G. lucidum compounds in the control of diseases in animals and humans. However, there is a lack of information on the effect of their compounds on the phytopathogens control, whether directly or by activating plant defense mechanisms. In the search of new molecules that has induced activity and disease control, this study was aimed to evaluate the bioactive compounds produced by G. lucidum through liquid culture under elicitation to control powdery mildew (Erysiphe diffusa) in soybean plants. The compounds tested were: C01-distilled water, C02-copper oxychloride (1 L ha-1), FC01-filtered mycelial growth of G. lucidum without elicitation, FC02-G. lucidum filtration of lignin elicitation and FC03-G. lucidum filtration from SA elicitation. The upper part of the plant was sprayed at 20 % (v/v) concentration and 10 mL per plant were applied. All data were analyzed using R&reg; software. The Ganoderma filtrates have shown the induction of resistance potential in soybean plants by the activation of phytoalexins, activation of the enzyme phenylalanine ammonia-lyase, increase of phenolic compounds, peroxidases and chitinase activity, such induction has specificity in relation to time activation and association with elicitors. New studies should be considered, seeking to identify and isolate the active principles present in the filtrates, as well as to evaluate the action of these substances in other pathosystems of agricultural interest.

Abstract:
Ganoderma species are one of the most widely researched fungi because of their reported potent bioactive properties. Although there is much information related to American, European and Asian isolates, little research has been conducted on Australian Ganoderma isolates. Ganoderma may only be imported into Australia under strict quarantine conditions, therefore, the isolation of a native strain that possesses bioactivity may be industrially and commercially significant. Three Australian species of this wood-decomposing fungus were isolated in northern Queensland. In this study, they have been identified as three separate species. Further, they have been studied to determine their optimal growth conditions in liquid culture and assessed for their antibacterial properties. Phylogeny inferred from the Internal Transcribed Spacer Regions (ITS) from the DNA sequences resolved the three Australian Ganoderma species into separate clades. Two isolates were identified to be isolates of Ganoderma cupreum (H1) and Ganoderma weberianum (H2). The third isolate could only be identified to the genus level, Ganoderma species, due to the lack of informative data that could be used for comparison. The effects of short term and long term storage on the viability of the fungi were investigated on agar plates, agar slants and balsa wood at varying temperatures ranging from 10 to 45�C. The most appropriate storage conditions were determined to be �80�C on balsa wood chips for periods of up to 2 years without subculture, and on agar slants at 4�C for up to a maximum of eight weeks. Light was observed to be detrimental to the survival of Ganoderma H1 and Ganoderma H2 during storage. Growth trials using potato dextrose agar plates determined the optimal temperature and pH for mycelial growth to be 30�C and a pH of 6, for all isolates. Subsequent growth trials in liquid media found that glucose, as the carbohydrate source, supported the greatest mycelial growth of Ganoderma H1 and Ganoderma H2 and that galactose and fructose supported the greatest growth of Ganoderma H3. Abstract ii Aqueous (hot water) and organic (hexane (HEX), dichloromethane (DCM), ethyl acetate (EtOAc), methanol (MeOH)) extracts from the liquid cultivated mycelium were assessed for their antibacterial activity using disc diffusion assays. Extracts from the mycelium of Ganoderma H1 exhibited activity against a greater number of Gram positive bacteria than those from Ganoderma H2 and H3. Subsequent studies on the DCM and EtOAc extracts from Ganoderma H1 determined the MIC and MBC against a number of Gram positive bacteria, including Bacillus cereus, B. subtilis, Enterococcus faecalis, Streptococcus pyogenes, Staphylococcus aureus, S. epidermidis and Listeria monocytogenes, as well as Clostridium species, including Clostridium perfringens, C. sporogenes and C. difficile, and some methicillin resistant Staphylococcus aureus (MRSA) strains. Time course growth assays confirmed that the DCM and EtOAc extracts predominantly exhibited bactericidal activity. Finally, the active compounds were determined to be terpenoid in structure with some phenolic groups attached.

Geographically, Arizona can be divided roughly into four areas, southwest, central, southeast, and northern. These regions correspond with four climatic zones, allowing a large and diverse number of plants to be grown for landscaping purposes. But, interestingly, in this desert environment many of the parasitic diseases in landscape plants are caused by a limited number of plant pathogens. This publication discusses some of those diseases that are sufficiently important to the urban plants in all areas Arizona.

Abstract:
Herbal medicine is now globally accepted as an authenticated alternative system of therapy in the form of pharmaceuticals, functional foods, and nutraceuticals; a trend recognized and supported by the World Health Organization (WHO). For decades herbal drugs have shown to be promising for a number of diseases and their use has been supported by physicians and patients for their improved therapeutic benefits as they have less adverse effects when compared with many modern medicines. In this thesis, it was decided to explore the therapeutic potential of n- hexane, DCM and methanol crude extracts from the Nigella sativa plant obtained by using novel Soxhlet extraction. The studies have been conducted on the antibacterial activity of these crude extracts of Nigella sativa and also demonstrated the in vitro antitumour potential of the above crude extracts of the plant. The results indicated that hexane extract of Nigella sativa seeds showed the most potent antibacterial and antitumour activity. The research also aimed at designing novel drug delivery systems for herbal constituent. Lipid emulsion (Intralipid) as a drug carrier was selected to carry the hexane extract obtained from one Soxhlet cycle extraction from the Nigella sativa seeds and determined its antitumour effects. This herbal formulation was investigated using both in vitro and in vivo target systems. Both, in vitro and in vivo findings showed that the Intralipid could carry the active ingredient(s) of the hexane extract across the filtered membrane and the drug carrier (IL) showed the minimal toxicity. Furthermore, the possibility of using ultrasound to enhance the cytotoxicity of the herbal drug formulation was explored using both in vivo and in vitro target system. The results suggested that ultrasound enhanced the therapeutic potential of the antitumour herbal drug in both the systems.

Abstract:
A new disease affecting potatoes was first detected in Mexico in 1993. Affected plants had aerial symptoms similar to those caused by potato purple top and psyllid yellows, but tubers had internal brown discoloration when sliced and dark stripes and streaks when processed to produce potato chips. The disease has been found in many potato production areas in Guatemala, Mexico, Honduras, New Zealand and the United States. The disease, termed Zebra Chip (ZC), has been associated with the presence of heavy infestations of the potato-tomato psyllid (Bactericera cockerelli). In 2009, a research group in New Zealand discovered that a new disease in tomato and pepper plants was caused by Candidatus Liberibacter solanacearum (Lso) and subsequently this same bacterium was associated with ZC in potato samples from Texas. The objectives of this study were: to assess the accumulation of Lso in various potato organs, to determine the effect of plant age on detection of Lso, symptom development and plant death, and (iii) to determine the effect of phosphorous acid on the development of ZC. Results from these studies showed significant differences in Lso populations between above and below ground tissues of the potato plant, with Lso populations in stolons and tubers being three to four times higher than those of leaf tissue and over seventy times greater than in stems. Time for detection of Lso by PCR in potato leaves of different ages at the time of inoculation ranged from 21 to 26 days after inoculation, symptoms development took 23 to 36 days. Plant death, took 24 to 47 days in plants of different age groups at the time of inoculation. In plants 15 weeks old at the time of inoculation, Lso was detected after 14 days in one plant out of 18; in plants 16 weeks old at the time of inoculation, Lso was detected after seven days in two plants out of 18. Phosphorous acid applications had no effect on the populations of Lso in potato tubers, onset of symptoms or plant death. All tubers showed ZC symptoms, making them unacceptable for the market.

Full text
Abstract:
The fungus Botrytis cinerea is an opportunistic pathogen on a wide variety of crops, causing disease known as grey mould through infections via wounds or dead plant parts. Synthetic fungicides for controlling this disease are fast becoming ineffective due to the development of resistance. This, coupled with consumers world wide becomng increasingly conscious of potential environment and health problems associated with the build up of toxic chemicals, (particularly in food products), have resulted in pressure to reduce the use of chemical pesticide volumes as well as its residues. An emerging alternative to random synthesis is the study and exploitation of naturally occurring products with fungicidal properties. There have been reports on the uses of synthetic fungicides for the control of plant pathogenic fungi. When utilized in two-way mixtures, such fungicides may maintain or enhance the level of control of a pathogen at reduced rates for both components utilized in combinations, or alone at normal rates. For this study it was hypothesize that the addition of plant extracts may enhance the antifungal efficacy of the synthetic strobilurin fungicide, kresoxim-methyl against Botrytis cinerea.

Abstract:
The work presented in this thesis is in two areas - study of novel pathogens resulting from new encounters between crop and native species and 'mining' for plant virus resistance genes in the model legume Medicago truncatula. The history of agriculture in Western Australia (WA) is less than 150 years old. All major broadacre and horticultural crops grown in WA have been introduced from overseas. These introduced horticultural and field crops potentially carry pathogens which may be transferred to infect native vegetation. Conversely, cultivated plants are vulnerable to infection by pathogens present in indigenous plants. This potential for new disease encounters is compounded by expansion of agriculture to crop new land and by predicted climate changes. These changes may provide selective advantage to a particular pest or disease, enabling infection to increase and so increase crop losses or damage native species. Global trade in agricultural produce also increases the potential for introduction of exotic pathogens. The focus of the first part of the research was to look for new pathogens of crops and native plants in WA. A series of field trips to study diseases in horticultural crops and native vegetation were made in the agricultural regions of Carnarvon, Broome, Kununurra, Perth and the surrounding metropolitan area. Although the initial focus was on virus diseases, the work expanded to study phytoplasma-associated diseases, because of their widespread occurrence and clear symptoms. In the agricultural region around Kununurra the potyvirus Bean common mosaic virus (BCMV) was found infecting Phaseolus vulgaris crops. Sequencing of isolates collected provided the first reliable molecular confirmation of the presence of BCMV in Australia. In joint work with K. Bayliss three commercial Paulownia tree plantations near Perth were found exhibiting symptoms of Witches'-Broom disease. The Paulownia trees were found to be associated with 'Candidatus Phytoplasma australiense' 16SrXII group. Chickpeas in the Kununurra region were found with symptoms of stunting, little leaf and proliferating branches and tested positive for phytoplasma. Sequencing confirmed the presence of a phytoplasma with high similarity to the 16SrII group 'Ca Phytoplasma aurantifolia' (peanut witches broom group). This is the first molecular evidence for a phytoplasma-associated disease in chickpea. Red clover (Trifolium pratense), several other pasture legumes and paddy melon (Cucumis myriocarpus) with symptoms of diminished leaf size, pallor, rugosity, leaf deformation, shoot proliferation and stunting were observed amongst pasture plots in south-western Australia. All species with these symptoms were positive for a phytoplasma resembling 'Ca Phytoplasma australiense, 16SrXII group. This association was confirmed for red clover and paddy melon by subsequent nested PCR and sequence analysis. This is the first time that 'Ca. Phytoplasma australiense, 16SrXII group, has been reported infecting these hosts in southern WA. Snakebean (Vigna unguiculata var. sesquipedalis) and tomato (Lycopersicon esculentum) plants with phytoplasma-like symptoms were found in the horticultural region at Broome. The symptoms on snakebean were typical of phytoplasma disease. Sequence analysis identified that the agent associated with the symptoms as a strain of sweet potato little leaf strain V4 (SPLL-V4) phytoplasma (16SrXII group, strain of 'Ca Phytoplasma australiense'). SPLL phytoplasma has not been reported in snakebean or tomato in this isolated agricultural region. In a survey in the Gascoyne region phytoplasma-like symptoms were found in tomato, eggplant and papaya. Previously in this region plants had been found to be associated with peanut witches broom phytoplasma 16SrII group 'Ca Phytoplasma aurantifolia'. Phytoplasma-like symptoms which included bunchy growth, witches' broom and 'little leaf' were observed in Allocasuarina fraseriana (Western Sheoak, Casuarina) and Acacia saligna (Acacia, Orange Wattle) trees in Kings Park and Botanic Garden Perth WA. Phytoplasma-associated disease was confirmed for the first time in native Australian casuarina and acacia trees in WA. Based on the identification of these phytoplasma associated diseases in WA, phytoplasma-associated diseases can be divided into two zones, because phytoplasma 16SrII group was found mostly in the north west of WA and the 16SrXII group in the south west of WA. This work has added to knowledge of the extent and distribution of phytoplasma disease in WA: it is concluded that crop-associated phytoplasma disease originated from native vegetation. The aim of the second part of the research was to screen and map a virus resistance gene in the model legume M. truncatula to better understand host/pathogen interactions of legume-infecting viruses. Natural resistance genes found in M. truncatula could then be used to locate similar genes in grain legumes (e.g. chickpea and lupins) for practical applications. M. truncatula is a model legume which has a relatively small genome. International consortia have been established to develop genomic resources for M. truncatula. The M. truncatula core collection (from SARDI, South Australia) totalling 230 accessions was screened for resistance/susceptibility to four legume-infecting viruses: Alfalfa mosaic virus (AMV), Cucumber mosaic virus (CMV), Bean yellow mosaic virus (BYMV) and Subterranean clover mottle virus (SCMoV). Five plants from each of the 230 phenotypically distinct members of the M. truncatula core collection were challenged with one isolate of each virus using infectious sap together with five uninoculated control plants for each accession. The symptoms that developed were recorded and virus presence was confirmed by ELISA for inoculated and systemic leaves. Accessions that were potentially resistant were retested to check for escapes. The result from this screen was that 5 accessions were potentially resistant to AMV, 56 to BYMV, 21 to CMV and 42 to SCMoV. The remaining accessions were susceptible to all four viruses with symptoms which ranged from no apparent symptoms (symptomless systemic infection) to highly susceptible and plant death. In continuing work with DAFWA (Dr R. Jones) accessions potentially resistant to AMV, BYMV and CMV are being challenged with additional isolates to check for the presence of genes providing broader resistance. The Sobemovirus SCMoV was chosen for further study because it is the most widespread viral pathogen of subterranean clover pastures in Australia. It is also a high titre, mechanically transmitted virus which gave the least escapes on infection. SCMoV has a linear, single-stranded positive-sense RNA genome of 4.25 Kb. Making use of natural resistance is an effective means to reduce pasture losses caused by SCMoV. From the screen of the core collection of M. truncatula, amongst the lines resistant to SCMoV a single dominant hypersensitive resistance was detected in line DZA-315. To accelerate mapping of the SCMoV resistance gene, an F8 RIL population of a cross between the resistant line (DZA-315) and a susceptible line (Jemalong-J6, A-17) was sourced and obtained from INRA Toulouse. A total of 166 RILs were phenotyped for resistance and susceptibility to SCMoV. Resistant and susceptible lines showed parental phenotypic symptoms with 84 being susceptible and 82 being resistant. This indicated the presence of a single resistance (R) gene. This phenotypic data was combined with genotypic data (76 polymorphic molecular markers) already available for this RIL population to provide a framework map. Mapmaker and Mapmanager mapping programs were used to locate the position of the resistance gene. This framework map indicated a position for the resistance gene on the long arm of chromosome 6. Additional polymorphic SSR markers flanking the R gene locus on chromosome 6 were used to map the position of the R gene more closely. These SSR markers were developed from a parental cross of M. truncatula line A17 and A20 at UC Davis and from a parental cross between line A17 and DZA 315 developed at INRA Toulouse. Ten new polymorphic SSR markers were identified and located on the long arm of chromosome 6 after analysis of the F8 RIL population. When combined with the other phenotypic and genotypic data a more accurate map position for the SCMoV R gene was obtained. The results indicate that the R gene to SCMoV is located on the long arm of M. truncatula chromosome 6 between position 35 to 38 centimorgans (cM). The closest marker to the SCMoV R gene is marker mtic153 which is about 2.3 cM away. From existing maps of M. truncatula most of the R genes located in this region are of the TIR-NBS-LRR type and occur in R gene clusters. A series of BACs that span the region of interest have been identified in which SCMoV R gene should be present. M. truncatula has been used as a model legume to study a number of symbiotic (e.g. rhizobium) and pathogenic interactions (e.g. fungal and nematode), but this is the only example of its use to study legume-virus interactions. The results obtained indicate the potential of using M. truncatula as a model to study resistance response to other legume viruses and provide a firm basis for identifying the hypersensitive R gene that confers resistance to SCMoV.

Abstract:
One of the more important uses of the “99 Diseases of Hydrocarbon Process Equipment”(1) is to determine how to safely operate process pressure equipment. Such a work process thereby minimizes the impact of any potential degradation mechanisms (the 99 Diseases), by establishing the appropriate boundaries for long and short-term safe process operation. Such boundaries are called Integrity Operating Windows (IOW’s)(1).
