dc.description.abstract |
Citrus leaves and fruits exhibiting disease
symptoms ranging from greasy spot, yellow spot, small
or large brown spot, black dot, and brown dot were
sampled from Fujian, Guangdong, Guizhou, Hunan,
Jiangxi, Yunnan, Zhejiang provinces and the Guangxi
Zhuang Autonomous Region in China. In total 82 isolates
representing various cercosporoid genera were
isolated from these disease symptoms, which were supplemented
with eight Citrus cercosporoid isolates
collected from other countries. Based on a morphological
and phylogenetic study using sequence data from
the nuclear ribosomal DNA’s ITS1-5.8S-ITS2 regions
(ITS), and partial actin (act), b-tubulin (tub2), 28S
nuclear ribosomal RNA (28S rDNA) and translation
elongation factor 1-a (tef1) genes, these strains were
placed in the following genera: Cercospora, Pallidocercospora,
Passalora, Pseudocercospora, Verrucisporota and Zasmidium.
All isolates tended to be sterile, except the
Zasmidium isolates associated with citrus greasy spotlike
symptoms, which subsequently were compared
with phylogenetically similar isolates occurring on
Citrus and other hosts elsewhere. From these results
four Zasmidium species were recognized on Citrus,
namely Z. indonesianum on Citrus in Indonesia, Z. fructicola and Z. fructigenum on Citrus in China and
Z. citri-griseum, which appears to have a wide host range
including Acacia, Citrus, Eucalyptus and Musa, as well as
a global distribution. |
