Endogenous polyamine profiles in different tissues of Coffea sp., and their levels during the ontogeny of fruits

Polyamines are essential compounds for
growth and development in plants. An attempt has been
made to find out the endogenous polyamine profiles in
various parts and during the ontogeny of fruit formation of
two commercially important Coffea species viz., arabica
and canephora. Putrescine (Put), spermine (Spm) and
spermidine (Spd) are the predominant polyamines during
the ontogeny of fruit and their level increased with the
advancement of fruit development. However, in the initial
stages of flower and fruit development Spm levels were
found to be decreased. Elevated levels of major polyamines
Put, Spd, and Spm were observed in zygotic embryos than
in somatic embryos. Along with this cadavarine (Cad) and
other biogenic amines viz., tyramine (Tyr) and tryptamine
(Try) were also found during the ontogeny of fruit in
C. canephora. In this study the enodogenous polyamine
profiles in coffee tissues and beans have been addressed.
