In addition pericarp cell wall loosening by XET may be required to maintain tissue pressure essential to normal growth and development. The Nahuatl (the language used by the Aztecs) word tomatl gave rise to the Spanish word tomate, from which the English word tomato derived. The species originated in western South America and Central America. In this work, we present an extended characterization of the proteome of the tomato pericarp at its ripe red stage. The locules are surrounded by the pericarp. The tomato is fleshy due to the pericarp walls and skin. The pericarp includes the inner wall, columella; the radial wall, septa; and the outer wall. Tomato fruits from all stages were dissected into three regions, and measured fresh weights of skin (exocarp, approximately 250 mg), outer pericarp region (hypodermis and outer mesocarp): the first 2 mm inside the skin (1–1.5 g), and inner pericarp region (mesocarp): 3–10 mm inside the skin (1–1.5 g), were extracted fresh or after freezing in liquid N and storage at −65 °C. 0000011310 00000 n Finally there are several seeds in each tomato. trailer << /Size 418 /Info 347 0 R /Root 353 0 R /Prev 1174977 /ID[<9c1569ebb4a601d046002052964564e1>] >> startxref 0 %%EOF 353 0 obj << /Type /Catalog /Pages 350 0 R /Metadata 348 0 R /Names 354 0 R /PageLabels 346 0 R >> endobj 354 0 obj << /Dests 344 0 R >> endobj 416 0 obj << /S 635 /T 819 /E 878 /L 894 /Filter /FlateDecode /Length 417 0 R >> stream 2.
