Distribution of Geotrichum candidum citrus race in citrus groves and non-citrus fields in Japan

First Report of Sour Rot on Post-harvest Oriental Melon, Tomato, Cucumber, Potato, Pumpkin and Carrot Caused by Geotrichum candidum

“…Korea (Park, 1961;Song, 1997;Hyun, 2002). However, it has been known to have ability to infect several postharvest plants, such as citrus fruit (Suprapta et al, 1995;Butler et al, 1988), peach (Crisosto et al, 2004Wells, 1977), tomato (Oladiran et al, 1993), apple, pear, egg plant, carrot, cucumber, guava, melon, papaya, pumpkin, sponge gourd and turnip (Fatima et al, 2009;Saude et al, 2005) throughout whole countries. This is first report of sour rot on vegetables like oriental melon, tomato, cherry tomato, cucumber, potato, pumpkin and carrot caused by G. candidum.…”

Differentiation of pathogenic and nonpathogenic isolates of Geotrichum candidum sensu Suprapta et al. (1995) on citrus fruit based on PCR-RFLP analysis of rDNA ITS and PCR using specific primers designed in polygalacturonase genes

“…In Japan, however, the sexual stage has not yet been found, and development of the stage also has not been demonstrated. In recent work on citrus sour rot, G. candidum citrus race is commonly cited to indicate the citrus sour rot pathogen Mor et al 1984;Baudoin and Eckert 1985;Chalutz and Wilson 1990;Wild 1992;Suprapta et al 1995Suprapta et al , 1996aNakamura et al 2001Nakamura et al , 2003; therefore, in this article, we adopt the name of G. candidum sensu Suprapta et al (1995). In addition, because, in plant pathology, the term race is used to express strains that show different pathogenicity on different cultivars, the terms citrus race and noncitrus race are not appropriate.…”

“…Butler et al (1965) reported that the pyridoxine Abstract Pathogenic and nonpathogenic isolates of Geotrichum candidum sensu Suprapta et al (1995) that affect citrus fruit are indistinguishable morphologically. In this work, differentiation of the two pathogenicity types based on the internal transcribed spacer regions of ribosomal DNA (rDNA-ITS) and polygalacturonase (PG) genes was attempted.…”

“…In 1965, Butler et al designated G. candidum as the causal agent of citrus sour rot and they gave the term of citrus race to this pathogen to differentiate it from the noncitrus isolates based on pathogenicity on citrus fruit and physiological characteristics, although citrus race and noncitrus isolates are indistinguishable morphologically (Butler et al 1965). Suprapta et al (1995) referred to the noncitrus isolates as noncitrus race. Later on, Butler et al (1988) also designated the causal agent of citrus sour rot as Geotrichum citri-aurantii (Ferr.)…”

“…Differentiation of pathogenic and nonpathogenic isolates of Geotrichum candidum sensu Suprapta et al (1995) on citrus fruit based on PCR-RFLP analysis of rDNA ITS and PCR using specifi c primers designed in polygalacturonase genes have been used to designate the pathogen. In 1965, Butler et al designated G. candidum as the causal agent of citrus sour rot and they gave the term of citrus race to this pathogen to differentiate it from the noncitrus isolates based on pathogenicity on citrus fruit and physiological characteristics, although citrus race and noncitrus isolates are indistinguishable morphologically (Butler et al 1965).…”
