Descrição: Analysis of 2479 ESTs from Vitis vinifera berry tissue and 2438 from leaf revealed that 1% of the ESTs match to known Vitis proteins, 72% to plant proteins, 11% to non-plant, and 16% had no match ( P[ N]>0.5). The levels of redundancy were similar in the leaf and berry libraries. Only 12% of the genes matched by the ESTs were common to both libraries indicating marked differences in the genes expressed in the two tissues. The abundance of transcripts with predicted cellular roles in leaf and berry were estimated by classifying the primary BLAST matches to known proteins (score >80) into functional categories. Thirty-six percent of the leaf transcripts were involved in photosynthesis, compared to 3% in the berry. This is a much higher proportion of transcripts involved with a function limited to specialized cells, than was found when transcripts of 33 human tissues were compared using a similar approach, suggesting plant cells may involve their cellular machinery to a greater extent in specialized activities than animal cells. Relatively enhanced expression of specific transcription factors, and genes involved in defense, detoxification, stress response, proteolysis, trafficing, and signal transduction, suggests berry tissue is actively engaged in responding to environmental stimuli.
