Colletotrichum sublineola is a filamentous fungus that causes anthracnose disease on sorghum. We report a draft whole-genome shotgun sequence and gene annotation of the nuclear genome of this fungus using Illumina sequencing.
Paecilomyces hepiali is an endoparasitic fungus that commonly exists in the natural Cordyceps sinensis Here, we report the draft genome sequence of P. hepiali, which will facilitate the exploitation of medicinal compounds produced by the fungus.
The fungus Rhizopus oryzae which belong to the order Mucorales is a unique test agent to study the effects of metabolic alterations on infection since it behaves differently in the metabolically normal and abnormal host. This fungus was originally isolated at autopsy from a diabetic patient who died with cerebral mucormycosis.' We have shown in previously reported experiments that inoculation o...
In a survey for Cryphonectria and Chrysoporthe species on Myrtales in South Africa, a fungus resembling the stem canker pathogen Chrysoporthe austroafricana was collected from native Syzygium cordatum near Tzaneen (Limpopo Province), Heteropyxis canescens near Lydenburg (Mpumalanga Province) and exotic Tibouchina granulosa in Durban (KwaZulu-Natal Province). The fungus was associated with dying...
Magnaporthe oryzae, the fungus causing rice blast disease, should contend with host innate immunity to develop invasive hyphae (IH) within living host cells. However, molecular strategies to establish the biotrophic interactions are largely unknown. Here, we report the biological function of a M. oryzae-specific gene, Required-for-Focal-BIC-Formation 1 (RBF1). RBF1 expression was induced in app...
Inoculation of the grapevine (Vitis amurensis Rupr.) with the arbuscular mycorrhizal (AM) fungus Glomus versiforme significantly increased resistance against the root-knot nematode (RKN) Meloidogyne incognita. Studies using relative quantitative reverse transcription-PCR (RQRT-PCR) analysis of grapevine root inoculation with the AM fungus revealed an up-regulation of VCH3 transcripts. This incr...
Fungus-growing ants (Attini: Formicidae) engage in an obligate mutualism with fungi they cultivate for food. Although biologists have been fascinated with fungus-growing ants since the resurgence of natural history in the modern era, the early stages of research focused mainly on the foraging behavior of the leaf-cutters (the most derived attine lineage). Indeed, the discovery that the ants act...
Leucoagaricus gongylophorus, the symbiotic fungus of the leaf-cutting ants, degrades starch, this degradation being supposed to occur in the plant material which leafcutters forage to the nests, generating most of the glucose which the ants utilize for food. In the present investigation, we show that laboratory cultures of L. gongylophorus produce extracellular alpha-amylase and maltase which d...
Giving and receiving: measuring the carbon cost of mycorrhizas in the green orchid, Goodyera repens.
Direct measurement of the carbon (C) 'cost' of mycorrhizas is problematic. Although estimates have been made for arbuscular and ectomycorrhizal symbioses, these are based on incomplete budgets or indirect measurements. Furthermore, the conventional model of unidirectional plant-to-fungus C flux is too simplistic. Net fungus-to-plant C transfer supports seedling establishment in c. 10% of plant ...
today, rocky monuments are being exposed to different physical, chemical and biological factors and therefore going to be ruined. one of physical destructive factors is growing of fungus and lichens on the rocks. this research aims to make use of silver nano-particles produced through microbial method in order to prevent growth and progression of fungus detached from rocky surfaces in meymand h...
