to have a role in sugar accumulation. BAIV pallalogues,
Lin5, Lin6, and Lin7 are present in tomato fruit, and
Lin6 was expressed specifically in sink organs and its
expression greatly increased with increases in sink
activity (Godt and Roitsch, 1997). Four AIV pallalogues
are present in the tomato; the expressions of two of these
pallalogues were correlated closely with sugar accumulation
in fruit (Husain et al., 2003)
