Tomato (Solanum lycopersicum L.) is one of the most
important horticultural crops. It has long served as a model
system for studying fleshy fruit development and ripening
owing to its relatively small genome, ease of genetic
manipulation, well‐characterized developmental mutants,
and relatively short life cycle. Tomato belongs to the climacteric
class of fruits, which includes banana, apple, and pear.
Most climacteric fruits show increased ethylene production
at or just before the onset of ripening and require ethylene
to complete the process (Alexander and Grierson, 2002).
Therefore, ethylene synthesis, perception, and signalling are
very important events for fruit ripening. The pathway of ethylene
biosynthesis has been determined (Adams and Yang,
1979). The key enzyme is 1-aminocyclopropane-1-carboxylic
acid (ACC) synthase (ACS), which regulates the production
of ACC from S-adenosylmethionine (SAM) (Alexander and
Grierson, 2002; Prasanna et al., 2007).
