This large class of organic hydrocarbons is distributed among all cellular organisms, including fungi. The different classes of terpenes produced by fungi are mono, sesqui, di- and triterpenes, although triterpene ergosterol is the main sterol identified in cell membranes of these organisms. The availability of genomic data from members in the Ceratocystidaceae enabled the detection and characterization of the genes encoding the enzymes in the mevalonate and ergosterol biosynthetic pathways. Using Citation: Sayari, M.; van der Nest, a bioinformatics approach, fungal orthologs of sterol biosynthesis genes in nine different species M.A.; Steenkamp, E.T.; Rahimlou, S.; of the Ceratocystidaceae were identified.

These fungi are mainly known as saprobes although some have been associated with disease symptoms. Six fungal isolates with typical culture characteristics of Huntiella spp. were collected from wounds on native forest trees in Greece and South Africa. The aim of this study was to identify these isolates, using morphological characters and multigene phylogenies of the rRNA internal transcribed spacer (ITS) region, portions of the β-tubulin (BT1) and translation elongation factor 1α (TEF-1α) genes.

Abstract In India pea is the second greatest protein source followed by chickpea for the people of the country, over the years due to pathogen attack and climate change, the yield of pea has reduced categorically which generated great concern among scientists, policymakers, and common people thus resulting into the development of strategies to assess the impact and severity of the disease spread around the country various measures were taken into the account to find out the best method to control the disease. It has been found that pea is most susceptible to fungal pathogens. After reviewing the literature it is deduced that there are enormous species of fungi reported showing beneficial as well as harmful relationships with the pea and other crop plants worldwide. Disease in the pea plant is mainly caused by microorganisms like fungi, bacteria, and some nematodes, but much of the losses are occurred due to fungal pathogens (generally soil-borne).

  • Black Root Rot of Cotton in Australia: the Host, the Pathogen and Disease Management
    CSIRO PUBLISHING Crop & Pasture Science, 2013, 64, 1112–1126 Review http://dx.doi.org/10.1071/CP13231 Black root rot of cotton in Australia: the host, the pathogen and disease management Lily L. Pereg Research Group of Molecular Biology, School of Science and Technology, University of New England, Armidale, NSW 2351, Australia. Email: [email protected] Abstract. Black root rot is a seedling disease caused by the soil-borne fungal pathogen Thielaviopsis basicola, a species with a worldwide distribution. Diseased plants show blackening of the roots and a reduced number of lateral roots, stunted or slow growth, and delayed flowering or maturity. It was first detected in cotton in Australia in 1989, and by 2004, T. basicola reached all cotton-growing regions in New South Wales and Queensland and the disease was declared as an Australian pandemic. This review covers aspects of the disease that have implications in black root rot spread, severity and management, including the biology and ecology of T. basicola, host range and specificity, chemical and biological control of T. basicola in cotton cropping systems, and crop rotations and host resistance. This review is of special interest to Australian readers; however, the incorporation of ample information on the biology of the pathogen, its interactions with plants and it relation to disease management will benefit readers worldwide. Received 1 July 2013, accepted 4 November 2013, published online 18 December 2013 Australian cotton plants, and delayed flowering or maturity. Belowground Cotton belongs to the genus Gossypium in the Malvaceae family symptoms include blackening of the roots and reduced number (USDA 2013b), and of the 17 native species of Gossypium in of lateral roots (Allen 2001).

  • A New Genus and Species for the Globally Important, Multihost Root Pathogen Thielaviopsis Basicola
    Plant Pathology (2017) Doi: 10.1111/ppa.12803 A new genus and species for the globally important, multihost root pathogen Thielaviopsis basicola W. J. Nela , T. A. Duongb , B. D. Wingfieldb, M. J. Wingfielda and Z. W. de Beera* aDepartment of Microbiology and Plant Pathology, Forestry and Agricultural Biotechnology Institute (FABI), University of Pretoria, Pretoria 0002; and bDepartment of Genetics, FABI, University of Pretoria, Pretoria 0002, South Africa The plant pathogenic asexual fungus Thielaviopsis basicola (Ascomycota) causes black root rot on many important agricultural and ornamental plant species. Since its first description in 1850, this species has had a tumultuous taxo- nomic history, being classified in many different genera. Thus far, DNA-based techniques have not played a significant role in identification of T. basicola and have been used only to confirm its placement in the Microascales. This investi- gation reconsidered the phylogenetic placement of T. basicola, using DNA sequence data for six different gene regions. It included 41 isolates identified as T. basicola from 13 geographical locations worldwide. Phylogenetic analyses showed that these isolates grouped in a well-supported lineage distinct from other genera in the Ceratocystidaceae, here described as Berkeleyomyces gen. nov. The data also provided robust evidence that isolates of T. basicola include a cryptic sister species. As a result, this report provides a new combination as B. basicola comb. nov. and introduces a new species as B. rouxiae sp. nov. Keywords: black root rot, phylogenetics, reference specimen, taxonomy Introduction In the late 1800s a sexual state, Thielavia (Th.) basi- cola Zopf, was described for T. basicola (Zopf, 1876).

  • ABSTRACT BECKER, LINDSEY ELIZABETH. Increased Flower
    ABSTRACT BECKER, LINDSEY ELIZABETH. Increased Flower Production and Plant Weight of Calibrachoa x hybrida by the Soil Fungus Mortierella elongata. (Under the direction of Dr. Marc A. Cubeta). Calibrachoa (Calibrachoa x hybrida), is a flowering ornamental plant, commonly known as a mini-petunia or million bells and is rapidly gaining popularity as a flowering bedding and hanging plant. It has a range of desirable horticultural characteristics, including attractive flowers, range of flower colors, drought tolerance, and plant habit. The saprobic fungus Mortierella elongata isolated as an endophyte from Populus deltoides (eastern cottonwood) roots has been shown to increase seedling growth of corn, red oak and tomato in pasteurized sand and untreated field soil. In this context, we conducted two greenhouse experiments in 2017 to evaluate the effect of potting media amendments of millet colonized with M. elongata at 1 and 2% (v/v) on plant growth of Calibrachoa cv. ‘Kabloom Deep Blue’ rooted cuttings. Plants were assessed weekly for flower production and at 86 days post inoculation for above/below ground dry weight. M. elongata isolate 624- significantly increased the number of flowers produced for inoculum volumes 1 and 2% over a period of 3- 5 weeks for both experiments and increased above and belowground plant dry weight during experiment 1. Our findings suggest that M. elongata 624- consistently promotes flower production of Calibrachoa. Calibrachoa, valued for its aesthetic qualities, requires constant surveillance for disease symptoms. Susceptibility of Calibrachoa to the soilborne fungal pathogen Thielaviopsis basicola (causal agent of black root rot) is informally well-known but has not been the subject of comprehensive investigation.
