The fungus Fusarium fujikuroi causes “bakanae” disease of rice due to its ability produce gibberellins (GAs), but it is also known for producing harmful mycotoxins. However, the genetic capacity whole arsenal natural compounds and their role in fungus' interaction with remained unknown. Here, we present a high-quality genome sequence F. that was assembled into 12 scaffolds corresponding chromosomes described fungus. We used along ChIP-seq, transcriptome, proteome, HPLC-FTMS-based metabolome...
Scientific communication is facilitated by a data-driven, scientifically sound taxonomy that considers the end-user's needs and established successful practice. In 2013, Fusarium community voiced near unanimous support for concept of represented clade comprising all agriculturally clinically important species, including F. solani species complex (FSSC). Subsequently, this was challenged in 2015 one research group who proposed dividing genus into seven genera, FSSC described as members...
The filamentous fungal ascomycete Colletotrichum magna causes anthracnose in cucurbit plants. Isolation of a nonpathogenic mutant this species (path-1) resulted maintained wild-type levels vitro sporulation, spore adhesion, appressorial formation, and infection. Path-1 grew throughout host tissues as an endophyte retained the range, which indicates that genetics involved pathogenicity specificity are distinct. Prior infection with path-1 protected plants from disease caused by...
ABSTRACT Strawberry anthracnose was observed for the first time in Israel 1995. The disease reached epidemic proportions Israeli nurseries and production fields 1995 1996. Using morphological cultural characteristics, species responsible identified as Colletotrichum acutatum. A reliable semi-selective medium, amended with iprodione lactic acid, used to isolate fungus from infected tissues. In addition, C. acutatum subsequently isolated necrotic roots of stunted, chlorotic plants that...
The invasive Asian ambrosia beetle Euwallacea sp. (Coleoptera, Scolytinae, Xyleborini) and a novel Fusarium that it farms in its galleries as source of nutrition causes serious damage to more than 20 species live trees pose threat avocado production (Persea americana) Israel California. Adult female beetles are equipped with mandibular mycangia which fungal symbiont is transported within from the natal galleries. Damage caused xylem associated disease symptoms include sugar or gum exudates,...
Species of the Fusarium fujikuroi species complex (FFC) cause a wide spectrum often devastating diseases on diverse agricultural crops, including coffee, fig, mango, maize, rice, and sugarcane. Although within FFC are difficult to distinguish by morphology, their genes share 90% sequence similarity, they can differ in host plant specificity life style. also produce structurally secondary metabolites (SMs), mycotoxins fumonisins, fusarins, fusaric acid, beauvericin, phytohormones...
Anthracnose disease caused by Colletotrichum species is a major constraint for the shelf-life and marketability of avocado fruits. To date, only C. gloeosporioides sensu lato aenigma have been reported as pathogens affecting in Israel. This study was conducted to identify characterize associated with anthracnose determine their survival on different host-structures The pathogen survived over-wintered mainly fresh dry leaves, well twigs orchard. A collection 538 isolates used this initially...
Fusarium oxysporum f.sp. cubense (Foc) is considered one of the most devastating soilborne fungal pathogens banana worldwide. Foc causing mortality to Cavendish group bananas, and belonging unique vegetative compatibility (VCG) 01213/16 has been termed tropical race 4 (TR4) currently renamed F. odoratissimum. The pathogen that was first detected approximately 50 years ago in South East Asia, since spread countries within greater Mekong subregion Australia. Recently, disseminated India,...
Anthracnose is one of the major fungal diseases strawberry occurring worldwide. In Israel, disease caused primarily by species Colletotrichum acutatum. The pathogen causes black spot on fruit, root necrosis, and crown rot resulting in mortality transplants field. host range specificity C. acutatum from was examined pepper, eggplant, tomato, bean, under greenhouse conditions. fungus recovered all plant over a 3-month period but symptoms only strawberry. Epiphytic endophytic (colonization)...
Abstract A nonpathogenic mutant ofColletotrichum magna (path-1) was previously shown to protect watermelon (Citrullus lanatus) and cucumber (Cucumis sativus) seedlings from anthracnose disease elicited by wild-type C. magna. Disease protection observed in stems of path-1-colonized cucurbits but not cotyledons, indicating that path-1 conferred tissue-specific and/or localized protection. Plant biochemical indicators a systemic (peroxidase, phenylalanine ammonia-lyase, lignin, salicylic acid)...
Isolates of Colletotrichum spp. from almond, avocado, and strawberry Israel isolates the pink subpopulation almond United States were characterized by various molecular methods compared with morphological identification. Taxon-specific primer analysis grouped avocado within species C. gloeosporioides U.S. Israeli acutatum. However, isolates, previously identified morphologically as gloeosporioides, reacted acutatum-specific primers. Arbitrarily primed polymerase chain reaction A+T-rich DNA...
This study was conducted to identify the species of Colletotrichum infecting tamarillo, mango, and passiflora in Colombia assess whether cross-infection between host is occurring. Isolates spp. from tamarillo (n = 54), 26), mango 15) were characterized by various molecular methods morphological criteria. Morphological characterization grouped isolates as C. acutatum gloeosporioides. Species-specific primer analysis reliable confirmed grouping (besides Tom-6) Man-76) However, DNA not...
One hundred twenty isolates of Colletotrichum gloeosporioides from avocado (6 U.S. and 57 Israeli isolates) almond (57 fruits were compared by various molecular methods a pathogenicity assay in order to determine the genetic diversity host specificity between among different populations. DNA eight additional anthracnose also compared. PCR amplification genomic with four primers produced uniform banding patterns for all geographic locations Israel. DNAs distinct isolates. In contrast, Israel...
A green fluorescent protein (GFP)‐expressing strain of Fusarium oxysporum f.sp . melonis race 1·2 (FOM 1·2‐GFP) was used to visualize infection a susceptible melon cultivar, Ein Dor (ED). At 1–2 days post‐inoculation (d.p.i.), the fungus grew on root epidermis and adhered epidermal cell borders. By day 4, mycelium crossed cortex endodermis through narrow pores in walls reached xylem vessels, where it sporulated produced secondary hyphae that upwards. Colonization dynamics ED seedlings were...
Crown and root rot of strawberry, caused by Macrophomina phaseolina, have become predominant soilborne diseases strawberry in Israel over the past 5 years. In total, 151 isolates pathogen were isolated from infected plants commercially grown cultivars onto a modified agar medium for genus Macrophomina. Sclerotia viability declined more rapidly soil maintained at 25°C or temperatures fluctuating 18 to 32°C under greenhouse conditions, compared with sclerotia kept 30°C. After 30 40 weeks...
The primary objective of this study was to characterize Fusarium spp. associated with the economically devastating mango malformation disease (MMD) in Mexico. In all, 142 strains were isolated from symptomatic inflorescences and vegetative tissues eight geographically diverse Mexican states 2002 through 2007. Initially, all isolates screened for genetic diversity using appolymerase chain reaction random amplified polymorphic DNA markers grouped into seven distinct genotypes. Based on results...
