“…It was not until 1987, when the first BFB outbreak occurred in the Mariana Islands (Wall and Santos, 1988) and entire fields of watermelon were lost as a result of fruit infection, that the destructive potential of this pathogen was appreciated. Additional outbreaks in commercial watermelon fields followed rapidly, including high yield losses in Florida, Indiana, Delaware and Texas (Black et al, 1994;Evans and Mulrooney, 1991;Latin and Rane, 1990;Somodi et al, 1991). BFB outbreaks in the USA in the mid-1990s led to numerous lawsuits filed by growers against vegetable seed companies.…”

“…2), mainly through international production and the sale of contaminated seeds. To date, BFB outbreaks have been reported in the Americas, Asia, Europe, Africa, the Middle and Far East, and Australia (Amadi et al, 2009;Black et al, 1994;Burdman et al, 2005;Evans and Mulrooney, 1991;Holeva et al, 2010;Latin and Rane, 1990;Mirik et al, 2006;O'Brien and Martin, 1999;Palkovics et al, 2008;Park et al, 2008;Ren et al, 2006;Schaad et al, 2003;Somodi et al, 1991;Walcott et al, 2004). Alarmingly, it is also possible that the pathogen can be spread via the seeds of nonhost plants.…”

“…citrulli was first recovered from watermelon foliage at the USDA plant introduction station, Griffin, GA in 1965 (Webb and Goth, 1965; Schaad et al., 1978); however, in 1989 a highly aggressive strain was recovered from outbreaks in commercial watermelons in Florida (Somodi et al., 1991). Subsequently, numerous costly BFB outbreaks occurred throughout south‐eastern and mid‐western USA between 1989 and 1994 (Latin and Rane, 1990; Jacobs et al., 1992; Black et al., 1994).…”

Using DNA fingerprinting by pulse-field gel electrophoresis and repetitive extragenic pallindromic (REP)-polymerase chain reaction (PCR), two distinct groups were confirmed among 64 Acidovorax avenae subsp. citrulli strains collected from a range of cucurbitaceous hosts in the USA, China, Taiwan, Thailand, Canada, Australia, Brazil and Israel. Eighty-two percent of the group I strains were recovered from non-watermelon hosts and the subspecies type strain was the only member of this group that utilized l-leucine as a sole carbon source. On the contrary, 94% of the group II strains were recovered from watermelon and 96% of them utilized l-leucine. Two-week-old watermelon cv. Crimson sweet, cantaloupe cv. Athena, pumpkin cv. Lumina and squash cv. Early yellow crookneck seedlings were susceptible to A. avenae subsp. citrulli strains representing each group with the exception of the subspecies type strain. Overall, seedlings of watermelon cv. Crimson Sweet were most susceptible to A. avenae subsp. citrulli infection followed by cantaloupe, pumpkin and squash. Group II strains were more aggressive watermelon than on other hosts. On the contrary, group I strains were moderately aggressive on all cucurbit hosts tested.

“…citrulli, which causes bacterial fruit blotch (BFB) of cucurbits (Schaad et al 1978;Willems et al 1992). Since the outbreaks in commercial watermelon fields in the USA from the late 1980s to the 1990s (Black et al 1994;Evans and Mulrooney 1991;Hamm et al 1997;Jacobs et al 1992;Latin and Rane 1990;Somodi et al 1991), BFB has gained great importance. The disease has been observed in many countries and in other cucurbits such as melon (Isakeit et al 1997;Sowell 1981), squash (Langston et al 1999;Martin and Horlock 2002), and cucumber .…”

Bacterial fruit blotch of cucurbits is a destructive disease caused by Acidovorax avenae subsp. citrulli, which is a typical seedborne pathogen. In seed health testing for this disease, we have detected many strains of Acidovorax with some differences from A. avenae subsp. citrulli. Their 16S rRNA sequences were divided into six types. The most common sequence was completely consistent with that of A. avenae subsp. avenae originally isolated from rice. The other sequences were over 99% similar but not identical to those of A. avenae subsp. avenae and A. avenae subsp. citrulli. Some commercialized antibodies against A. avenae subsp. citrulli reacted with several of these strains. Some of these strains incited yellow spots or brownish water-soaked lesions mainly on young true leaves of cucumber and squash after spray inoculation. Histological observations showed that these strains entered the leaf tissues of cucurbit plants through stomata and multiplied in the intercellular spaces of parenchymatous tissues as well as in the vascular tissues. The amount of bacterial multiplication and spread in the tissues differed among the strains, presumably reflecting their ability to induce symptoms. These isolated strains are therefore different from A. avenae subsp. citrulli, and their potential threat to the cultivation of cucurbits is lower than that of A. avenae subsp. citrulli.
