| axillary bud | - |
Vitis vinifera | - |
| axillary bud | accumulation of product resveratrol | Vitis vinifera | - |
| leaf | low accumulation of product resveratrol, highest level of stilbene synthase mRNA and protein among the tissues analyzed | Vitis vinifera | - |
| leaf | highest STS content, lowest resveratrol content | Vitis vinifera | - |
| additional information | immunohistochemical analysis of the tissue-specific distribution of STS in different organs, overview. Distribution of resveratrol and STS in grape is organ-specific and tissue-specific. Highest content of resveratrol occurs in the stem phloems, followed by axillary buds, roots, stem xylems, shoot tips and petioles; and lowest in leaves | Vitis vinifera | - |
