Endophytic Colletotrichum (Sordariomycetes, Glomerellaceae) species associated with Citrus grandis cv. “Tomentosa” in China
Colletotrichum species are well-known plant pathogens, saprobes, endophytes, human pathogens and entomopathogens. However, little is known about Colletotrichum as endophytes of plants and cultivars including Citrus grandis cv. “Tomentosa”. In the present study, 12 endophytic Colletotrichum isolates...

Zusammenfassung: | Colletotrichum
species are well-known plant pathogens, saprobes, endophytes, human pathogens and entomopathogens. However, little is known about
Colletotrichum
as endophytes of plants and cultivars including
Citrus grandis
cv. “Tomentosa”. In the present study, 12 endophytic
Colletotrichum
isolates were obtained from this host in Huazhou, Guangdong Province (China) in 2019. Based on morphology and combined multigene phylogeny [nuclear ribosomal internal transcribed spacer (ITS), glyceraldehyde-3-phosphate dehydrogenase (
gapdh
), chitin synthase 1 (
chs-1
), histone H3 (
his3
) actin (
act
), beta-tubulin (β-
tubulin
) and glutamine synthetase (
gs
)], six
Colletotrichum
species were identified, including two new species, namely
Colletotrichum guangdongense
and
C. tomentosae
.
Colletotrichum asianum
,
C. plurivorum
,
C. siamense
and
C. tainanense
are identified as being the first reports on
C. grandis
cv. “Tomentosa” worldwide. This study is the first comprehensive study on endophytic
Colletotrichum
species on
C. grandis
cv. “Tomentosa” in China. |
