The fungal genus Monilinia comprises several aggressive and economically important plant pathogens. The aim of this study was to examine Monilinia species that belong to the Disjunctoriae group and are specifically pathogenic to Vaccinium hosts. 23 samples of Vaccinium hosts showing symptoms of infection with Monilinia sp. were collected in the years 2004 – 2009. Monilinia species were isolated...

The fruits showing brown rot symptom on dwarf flowering almond were found in Gongju, Chungchungnam-Do in Korea in July 2005. Small water-soaked lesions on the fruits were initiated, and gradually developed to soft rot covered with gray conidia. Then the diseased fruits were shrunk and became grayish-black mummies. A fungus was isolated from the diseased fruit and its morphological, cultural and...

In recent years, safer methods for the control of fruit postharvest pathogens have been investigated and heat treatment could represent an effective and safe approach for managing postharvest decay such as Monilinia rots. In the present study, the effect of hot water treatment (HWT) (60◦C for 30 and 60 s) on brown rot was investigated. More specifically, the influence of HWT was determined in i...

In this study, 145 peaches and nectarines displaying typical brown rot symptoms were collected from multiple provinces in China. A subsample of 26 single-spore isolates were characterized phylogenetically and morphologically to ascertain species. Phylogenetic analysis of internal transcribed spacer (ITS) regions 1 and 2, glyceraldehyde-3-phosphate dehydrogenase (G3PDH), β-tubulin (TUB2) reveale...

Monilia polystroma is the conidial form of an unknown apothecial ascomycete closely related to Monilinia fructigena, from which it has so far been distinguished by molecular means. Although M. fructigena and the other brown-rot species, M. fructicola and M. laxa, are known on various continents, Monilia polystroma was identified in Japan and initially known only in that country. A recent publis...

The genus Acanthaleyrodes Takahashi is reported for the first time from India. Acanthaleyrodes elevatus sp. n. is described from Bridelia retusa in Kerala, India, with a key to puparia of Acanthaleydes species. The new species differs in its exceptionally elevated eighth abdominal tergite, circular vasiform orifice and eight pairs of subdorsal setae. The generic characteristics of Acanthaleyrod...

The filamentous fungus, Lambertella corni-maris (L. corni-maris), a mycoparasite on Monilinia fructigena, produces the antibiotics, lambertellols A (1), B (2), and lambertellin (3), in a substantial amounts under acidic conditions, whereas these antibiotics were hardly detected when the fungus was cultured on a potato-sucrose (PS) medium without added acids. Our investigations also revealed tha...

known as denmert) caused total loss of its fungicidal activity towards Sphaerotheca fuliginea and Monilinia fmctigena. These workers suggested that the co-ordination of the heterocyclic meta-nitrogen atom of buthiobate to a cationic receptor site may be important for its fungicidal activity. The cationic receptor site mentioned would appear to be the Fez+ of the cytochrome P-450 catalysing step...
