AbstractPhytochrome-mediated light and temperature perception has been shown to be a major regulator of fruit development. Furthermore, chromatin remodelling via DNA demethylation has been described as a crucial mechanism behind the fruit ripening process; however, the molecular basis underlying the triggering of this epigenetic modification remains largely unknown. Here, an integrative analyses of the methylome, siRNAome and transcriptome of tomato fruits from phyA and phyB1B2 null mutants was performed, revealing that PHYB1 and PHYB2 influences genome-wide DNA methylation during fruit development and ripening. The experimental evidence indicates that PHYB1B2 signal transduction relies on a gene expression network that includes chromatin organization factors (DNA methylases/demethylases, histone-modifying enzymes and remodelling factors) and transcriptional regulators, ultimately leading to altered mRNA profile of photosynthetic and ripening-associated genes. This new level of understanding provides insights into the orchestration of epigenetic mechanisms in response to environmental cues affecting agronomical traits in fleshy fruits.

Cuticle Thickness

The cuticle of a plant plays an important role in many physiological events of fruit development and ripening. Despite this, little is known about cuticle formation and development. We include a detailed morphological study at the microscopic level of cuticle during fruit growth and ripening using tomato as a fruit model. In addition, a study of the differences in cuticle thickness and composition during development is included. The four genotypes studied in this work showed a similar timing of the main morphological events: initiation of epidermal differentiation, changes in the distribution of the lipid, pectin and cellulose material within the cuticle, appearance of pegs, beginning of cuticle invaginations, maximum thickness and loss of polysaccharidic material. Fruit growth, measured by fruit diameter, showed a positive correlation with the increase of cuticle thickness and the amount of cuticle and their cutin and polysaccharide components per fruit unit during development. By contrast, cuticle waxes showed a different behaviour. Two important characteristics of cuticle growth were observed during tomato fruit development. First, the amount of cuticle per surface area reached its maximum in the first 15 days after anthesis and remained more or less constant until ripening. Second, there was a significant loss of polysaccharidic material from the beginning of ripening (breaker stage) to full red ripe.
