Tissue-specific expression of the transcription factor, Nitf, in different tissues and organs of tomato seedlings grown under nutrient-sufficient hydroponical conditions. Lanes 1 and 2, Roots. Because the root system was relatively large, different parts of the roots were harvested and bulked. Lane 3, Older leaves harvested from below middle trusse of the plants. These are completely functioning leaves, healthy, not showing any aging symptoms. Lane 4, Young leaves harvested from the top of the plants. They were barely fully expanded. Lane 5, Flowers. Lane 6, Old stems. Main stems harvested from bottom part of the plants, directly above the root. Lane 7, Young stems. Main stems harvested from the top part of the plants. Lane 8, Unripe fruits. Green tomato fruits of various sizes. All tissues were harvested from the same plants at the same physiological age.
