WebJan 1, 1991 · Two cuts, one vertical and one horizontal, separated tissue flaps pointing towards and away from the original direction of the roots. New vessels (and other vascular tissues) formed only in the flap connected with the young leaves pointing in the original direction of the roots. WebJun 28, 2008 · At the tissue level, findings showed wild type cotyledons had a random stomatal pattern, whereas gl1–1 and try240 cotyledons had ordered and clustered stomatal patterns, respectively. Regardless of overall pattern type, c . 10% of the stomatal population – those closest to one another – were always ordered, the result of genes regulating ...
