Secondary cell-wall assembly in flax phloem fibres: role of galactans.

abstract：:In order to change the sugar status during seed development a yeast-derived invertase gene was expressed in cotyledons of Vicia narbonensis. As a result, sucrose decreased whereas hexoses accumulated. We analysed cell structure and cellular differentiation in cotyledons expressing the yeast-invertase. Transgenic cells...
