Mexico is one of the five largest producers of papaya worldwide,
but losses caused by pathogens, mainly fungus, at the
pre- and post-harvest stages are often more than 50% of the
crop. Papaya anthracnose, caused by three different species
of the Colletotrichum genus in Mexico, occupies a preponderant
place in this problem. Although two of these species,
C. gloeosporiodes and C. truncatum, have been characterized
morphologically and genotypically, this has not occurred with
C. magnum, the third species involved, about which there is
very little information. Because of this, it is vital to know its
genetic characterization, much more so considering that the
studies carried out on the other two species reveal a wide genetic
diversity, differences in pathogenicity and in the response
to fungicides of the different strains characterized.
In this work, Colletotrichum spp. isolates were collected at
different papaya orchards in the south-southeast of Mexico.
C. magnum isolates identified by species-specific primers
were characterized by morphological and molecular approaches.
Differences in colony characteristics resulted in five
morphological groups. AP-PCR, DAMD and ISSR markers
were found to be very efficient for revealing the interspecific
variability of this species. The high genetic variability found
in the accessions of C. magnum was linked to the geographical
area where they were collected. Isolates from Chiapas State
were the most variable, showing point mutations in the ITS1-
ITS2 region. These results will enable a better phytosanitary
management of anthracnose in papaya in this region
of Mexico.

Abstract

This study characterized Clavispora lusitaniae strains isolated
from different stages of the processing and early fermentation
of a henequen (Agave fourcroydes) spirit produced in
Yucatan, Mexico using a molecular technique. Sixteen strains
identified based on morphological features, obtained from
different substrates, were typed molecularly. Nine different
versions of the divergent D1/D2 domain of the large-subunit
ribosomal DNA sequence were identified among the
C. lusitaniae strains. The greatest degree of polymorphism
was found in the 90-bp structural motif of the D2 domain.
The MSP-PCR technique was able to differentiate 100% of
the isolates. This study provides significant insight into the
genetic diversity of the mycobiota present during the henequen
fermentation process, especially that of C. lusitaniae,
for which only a few studies in plants have been published.
The applied MSP-PCR markers were very efficient in revealing
polymorphisms between isolates of this species.
