Endophytes were found in all four anticancer plant species
with a total of 355 endophytes isolated from the 699 tissue segments
used. Endophytes were mostly recovered from P. bleo
(203 isolates), followed by O. diffusa (68 isolates), C. citratus
(49 isolates) and M. koenigii (35 isolates) (Fig. 1). It was also
observed that for all four plants, a higher number of endophytes
were recovered from leaf tissues than in stem tissues
(Fig. 1). This was most evident in P. bleo where 190 isolates
were found in leaf tissues compared to only 13 isolates from
stem tissues (Fig. 1). Due to the large number of endophytes,
the isolates were further grouped into 89 morphotypes with
each morphotype comprising of isolates with similar morphological
and cultural characteristics. P. bleo have the most morphotypes
(40 morphotypes), followed by O. diffusa (25 Colletotrichum (12 morphotypes), Fusarium (4 morphotypes),
Penicillium (2 morphotypes) and Phoma (1 morphotype).
