“…Therefore, they should be properly recognized as "family memberspecific" motifs, which might be cis-acting elements that confer additional regulatory properties to the basic, structurally invariant, I-G functional unit. This was suggested by the recent finding of a fruit-specific nuclear factor that binds to an IB-overlapping element (F-box) in tomato rbcS-3A (Meier et al, 1995). …”

“…The locular tissue is indeed capable of photosynthetic activity (Laval-Martin et al, 1977) and shows high promoter activity of Rubisco genes (Meier et al, 1995), despite its localization in locules surrounded by carpel walls (Fig. 4).…”

“…Since most of the studies to date have focused on the entire fruit or on the carpel wall, how the different fruit tissues contribute to fruit growth and affect fruit quality remains poorly understood. There are nevertheless some indications of early tissue specialization in the fruit, since structural and biochemical changes such as cell size (Mohr and Stein, 1969;Gillaspy et al, 1993), endoreduplication level (Joubès et al, 1999), photosynthesis (Laval-Martin et al, 1977;Meier et al, 1995), starch accumulation (Schaffer and Petreikov, 1997), cell wall polysaccharides (Cheng and Huber, 1996), and flavonoid composition (Muir et al, 2001) show great variation among the different fruit tissues. These data suggest coordinated expressions of genes with specific roles in the control of growth and regional differentiation in the various tissues of the developing fruit.…”

Changes in Transcriptional Profiles Are Associated with Early Fruit Tissue Specialization in Tomato

The cell expansion phase contributes in determining the major characteristics of a fleshy fruit and represents two-thirds of the total fruit development in tomato (Solanum lycopersicum). So far, it has received very little attention. To evaluate the interest of a genomic scale approach, we performed an initial sequencing of approximately 1,200 cell expansion stage-related sequence tags from tomato fruit at 8, 12, and 15 d post anthesis. Interestingly, up to approximately 35% of the expressed sequence tags showed no homology with available tomato expressed sequence tags and up to approximately 21% with any known gene. Microarrays spotted with expansion phase-related cDNAs and other fruit cDNAs involved in various developmental processes were used (1) to profile gene expression in developing fruit and other plant organs and (2) to compare two growing fruit tissues engaged mostly in cell division (exocarp) or in cell expansion (locular tissue surrounding the seeds). Reverse transcription-polymerase chain reaction analysis was further used to confirm microarray results and to specify expression profiles of selected genes (24) in various tissues from expanding fruit. The wide range of genes expressed in the exocarp is consistent with a protective function and with a high metabolic activity of this tissue. In addition, our data show that the expansion of locular cells is concomitant with the expression of genes controlling water flow, organic acid synthesis, sugar storage, and photosynthesis and suggest that hormones (auxin and gibberellin) regulate this process. The data presented provide a basis for tissue-specific analyses of gene function in growing tomato fruit.After ovule fertilization, early tomato (Solanum lycopersicum) fruit development is characterized by a period of cell division followed by cell expansion, resulting in the formation of large vacuolated cells (Mohr and Stein, 1969). Cell expansion is the longest phase in fruit development and may contribute to 90% of the increase in fruit weight, depending on the cultivar. In addition, cell expansion contributes, along with ripening, to the major structural, biochemical, and physiological changes that characterize a fleshy fruit. The cell wall changes associated with cell enlargement and the continuous accumulation in the vacuole of water, sugars, organic acids, and other compounds are necessary to maintain the turgor pressure of the expanding cells. In addition, these physiological processes contribute significantly to the flavor, texture, and overall attractiveness of the ripe fruit. The succession of the different phases of tomato fruit development is not, however, as clear cut as described above. It varies greatly according to the fruit tissue considered (Joubès et al., 1999). Tomato fruit is a complex organ composed of two or more carpels separated by a radially orientated tissue called septum, which results from the fusion of two adjacent carpel walls (or pericarp). The pericarp encloses the locular cavity containing the seeds attached to a central pa...

“…However, highresolution expression profiles in the homologous system are available only for selected members of the RbcS and Lhc families, specific organs, and few species (e.g. Jefferson et al, 1987;Langdale et al, 1988;Silverthorne and Tobin, 1990;Bansal et al, 1992;Meier et al, 1995;Fleming et al, 1996), and are lacking for any of the RbcS and Lhc genes in Arabidopsis.…”

Unique and Overlapping Expression Patterns among Members of Photosynthesis-Associated Nuclear Gene Families in Arabidopsis

Light provides crucial positional information in plant development, and the morphogenetic processes that are orchestrated by light signals are triggered by changes of gene expression in response to variations in light parameters. Control of expression of members of the RbcS and Lhc families of photosynthesis-associated nuclear genes by light cues is a paradigm for lightregulated gene transcription, but high-resolution expression profiles for these gene families are lacking. In this study, we have investigated expression patterns of members of the RbcS and Lhc gene families in Arabidopsis (Arabidopsis thaliana) at the cellular level during undisturbed development and upon controlled interference of the light environment. Members of the RbcS and Lhc gene families are expressed in specialized territories, including root tip, leaf adaxial, abaxial, and epidermal domains, and with distinct chronologies, identifying successive stages of leaf mesophyll ontogeny. Defined spatial and temporal overlap of gene expression fields suggest that the light-harvesting and photosynthetic apparatus may have a different polypeptide composition in different cells and that such composition could change over time even within the same cell.
