abstract = {Fleshy fruits are very varied, whether in terms of their
composition, physiology, or rate and duration of growth. To
understand the mechanisms that link metabolism to
phenotypes, which would help the targeting of breeding
strategies, we compared eight fleshy fruit species during
development and ripening. Three herbaceous (eggplant,
pepper, and cucumber), three tree (apple, peach, and
clementine) and two vine (kiwifruit and grape) species were
selected for their diversity. Fruit fresh weight and biomass
composition, including the major soluble and insoluble
components, were determined throughout fruit development and
ripening. Best-fitting models of fruit weight were used to
estimate relative growth rate (RGR), which was significantly
correlated with several biomass components, especially
protein content (R=84), stearate (R=0.72), palmitate
(R=0.72), and lignocerate (R=0.68). The strong link between
biomass composition and RGR was further evidenced by
generalized linear models that predicted RGR with R-values
exceeding 0.9. Comparison of the fruit also showed that
climacteric fruit (apple, peach, kiwifruit) contained more
non-cellulosic cell-wall glucose and fucose, and more
starch, than non-climacteric fruit. The rate of starch net
accumulation was also higher in climacteric fruit. These
results suggest that the way biomass is constructed has a
major influence on performance, especially growth rate.},
