“…For example, B. dothidea and B. ribis Grossenb. & Duggar have been viewed as distinct species by many due to differences in anamorph morphology (Punithalingam and Holliday 1973, MorganJones and White 1987, Rayachhetry et al 1996, Zhou and Stanosz 2001a, while others treated them as synonyms sensu von Arx and Mü ller (Witcher and Clayton 1963, Barr 1972, English et al 1975, Spiers 1977, Maas and Uecker 1984, Pennycook and Samuels 1985, Brown and Britton 1986, Smith et al 1994. A further basis for confusion is that von Arx and Müller (1975) considered B. berengeriana, which they had synonymized earlier with B. dothidea (von Arx and Müller 1954), as one of the most common species of the genus.…”

Abstract:Botryosphaeria dothidea is one of the most commonly reported species in a genus of important pathogens of woody plants. This taxon generally is accepted to represent a species complex, and hence its identity remains unclear. Previous studies either have treated B. dothidea as the valid name for B. ribis and B. berengeriana or argued for them to be separate entities. To add to the confusion, no ex-type cultures are available for either B. dothidea or B. ribis. The aim of the present study, therefore, was to recollect and characterize these fungi and designate a set of reference cultures that can be used in future studies. To this end, morphological, cultural and multi-allelic DNA sequence datasets from the rDNA (ITS 1, 5.8S, and ITS 2), ␤-tubulin and EF1-␣ genes were used to fully characterize these species. Botryosphaeria dothidea was found to be distinct from B. ribis, while B. berengeriana was retained as synonym of the former name. Furthermore, Fusicoccum aesculi is accepted as anamorph of B. dothidea, while the anamorph of B. ribis is newly described as F. ribis sp. nov. Botryosphaeria ribis could be distinguished from B. parva based on ␤-tubulin and EF1-␣ sequence data. A combined phylogeny of the three gene regions used in this study also showed that the genus Botryosphaeria rep-

“…Symptoms include gummosis and dieback of stone fruit trees in Egypt (Nattrass 1933), branch wilt and drying of grape vines in India and Iraq (Natour andAhmed 1969, Wangikar et al 1969), branch wilt, decline and death on citrus in Iraq (Alizadeh et al 2000), leaf spot diseases in India (Chandra 1974), leaf spot and dieback of mango in India and Niger (Pandey et al 1981, Reckhaus andAdamous 1987), and tip rot of bananas in Jamaica and Hawaii (Meredith 1963(Meredith , 1969. In North America F. dimidiatum has been reported in California to cause branch wilt and canker of walnut (Wilson 1947(Wilson , 1949, dieback and canker of citrus (Calavan and Wallace 1954), secondary canker infection of almond (English et al 1975) and a canker and dieback of Eucalyptus in Arizona (Matheron and Sigler 1993). The temperature minimum (15 C), optimum (30-35 C) and maximum (38-40 C) for growth of F. dimidiatum (Nattrass 1933, Wilson 1947) ranges about 5 C higher than for F. arbuti, which is 10, 25 and 30-35 C respectively (Davison 1972, Elliott 1999.…”

Pacific madrone (Arbutus menziesii) is a broadleaf evergreen tree native to western North America that has been in decline for the past 30 years. A fungus has been isolated and was verified as the cause of cankers on dying trees. It was determined to belong in the genus Fusicoccum, an asexual state of Botryosphaeria. This genus in both its sexual and asexual states commonly causes canker diseases of deciduous woody plants. Using morphological and molecular data the fungus causing cankers on Pacific madrone is characterized, described and illustrated as a new species of Fusicoccum, F. arbuti D.F. Farr & M. Elliott sp. nov. No sexual state is known for F. arbuti. Evidence from the literature, cultures and specimens suggests that F. arbuti, often mistakenly identified as Nattrassia mangiferae, has been causing madrone canker since at least 1968. Authentic isolates of Nattrassia mangiferae as the synanamorph Scytalidium dimidiatum were sequenced and determined to be different from Fusicoccum arbuti and to belong in Botryosphaeria/Fusicoccum. In addition to molecular sequence data, the morphology of the pycnidial and arthric conidial states of Nattrassia mangiferae/ Scytalidium dimidiatum resembles that of Fusicoccum. Therefore the correct name for Nattrassia mangiferae and its numerous synonyms (Dothiorella mangiferae, Torula dimidata, Scytilidium dimidiatum, Fusicoccum eucalypti, Hendersonula toruloidea, H. cypria, Exosporina fawcetii, H. agathidia, and S. lignicola) is Fusicoccum dimidiatum (Penz.)

Objective: The potential compound of taxol has been used treatment of cancer in the medical field. This study is focused on the extraction of taxol from Fusicoccum sp. Methods:The pathogenic strain was grown in MID medium for the taxol production and extracted from the Fusicoccum culture filtrate and processed to the ultraviolet (UV)-spectroscopy analysis as well as infrared (IR) spectra analysis was done, and the sample was performed to the high-performance column chromatography and further processed to the random amplified polymorphic DNA (RAPD) analysis of specific primer is PGFO1, PGFO2 are performed.Results: UV-visible spectral analysis showed maximum value for 273 nm. The result of IR-spectrum analysis to find out the functional groups present in sample and characteristic peak to conform the existences of OH group. The presence of taxol was confirmed using column chromatography. An analysis of taxol production was on the external standard of authentic taxol. The column chromatography process shows the amount of taxol production by Fusicoccum spp. 325 µg/L. RAPD analysis indicates the genetic relation among all isolates of fungus was analyzed by two random primers PGF01 and PGF02. Conclusion:The present investigation revealed that the taxol production from biological source was a significant effect, and the presence of taxol amount is analysis in Fusicoccum sp. 325 µg/L. The RAPD analysis of genetic stability of in vitro grown fungus and genotypic with two different primers shows that five fungus species with corresponding primer efficiency was amplified.
